[China Aluminum Industry Network] correctly and standardly using terminology can correctly transmit information and better communicate and spread. However, in real life, there are often some non-standard terms and terms, and even some errors may occur. the term. Now some of the non-standard terms and usages of the aluminum industry, especially the aluminum processing industry, are listed below. If we think that the author is right, I hope to adopt it.
The original aluminum primary aluminum is called Primaryaluminium. It can also be called primary aluminum. It is defined as: siphon from an aluminum cell to liquid aluminum in a ladle (pouring ladle). Then it is poured into the mixing furnace after weighing and poured into small ingots after purification. The mass of this small ingot is usually 20kg±2kg or 15kg±2kg or large T-bar, and it can also be mixed. The furnace is melted into an alloy for press working. The ingot cast from the raw aluminum purified by the purification process is called an aluminum ingot for remelting. According to GB/T1196-2008, there are eight types of aluminum ingots for remelting. Each package of primary aluminum must be measured in pounds and filled into the production card. This work is done either automatically or manually. Therefore, the output of primary aluminum should be accurate, unless artificially falsified, modify the data, in addition, you can also calculate the yield based on the theoretical formula, and the calculated output should be close to the actual output.
In the factory, primary aluminum is often referred to as aluminum water or aluminum melt. This is not proper, because aluminum water and aluminum melt are a broad term that refers to a variety of liquid aluminum, while primary aluminum is a specific term, of course, Raw aluminum is also a kind of aluminum water.
Aluminum and aluminum metal or aluminum and aluminum in English have two ways of writing: aluminum and aluminum, the former is British, the latter is American. The United States, Canada, Mexico, and Japan use the American style, while other countries and regions use the British style, and China should use the British style. When we talk and write articles, we don't say that metal aluminum or metal magnesium should be written into metal aluminum or magnesium metal. This is what foreigners say because it is not visible from aluminum whether it is metal or non-metal. Its shape at room temperature is solid, liquid, or gaseous, so it is written as aluminum metal, and the Chinese character is really great. If you look at the name of an element, you will know its attributes and forms. For example, if you say aluminum, we know that It is a metal that is solid at room temperature. Needless to say that metal aluminum or aluminum metal, in the written material should pay more attention to this point.
Rolling and calendering There are still a small number of individuals, individual factories, and even individual authoritative institutions in the aluminum processing industry in China. Rolling or milling is called calendering. The aluminum industry has a large aluminum built in the 1970s and 1980s. The processing plant called the strip workshop as a calendering plant after the calendering workshop. However, in the standard, textbooks, and dictionaries, they did not call for calendering. The steel industry calls it rolling, but it does not call it calendering. The “calendar†clause cannot be found in the Xinhua Dictionary, and the interpretation of rolling is “the process of applying the pressure between two oppositely rotating rolls to change the shape and properties of metallic materials.†in GB/T8005.1- In 2008 (anterior part of aluminum and aluminum alloy terms: product and processing technology), “calendering†is also explained, but the explanation for milling is “in the process of processing, the metal is on the upper and lower rollers of the rolling mill. The process of rolling is carried out to produce a veneer or a strip." Therefore, do not use the term "calendering," and the term "rolling" is used for the steel industry.
Thick plates, thin plates and plates Before the year 2002, China's aluminum processing industry did not speak of heavy plates. In one year, China had a state-owned comprehensive large-scale aluminum processing company planning to build a modern thick plate production line project. The application report on the construction of the heavy plate project was proposed in the project proposal report issued by the department. Since then, the technical term “plate†has been widely circulated in the Chinese aluminum industry. In fact, neither the world aluminum industry nor the aluminum processing industry in China has ever had the term “plateâ€, in GB/T8005.1-2008 (aluminum and aluminum alloy terminology part 1: products and processing technology) Only the sheet and plate entries are listed. Thin plate definition: Thickness greater than 0.20mm and greater than 6mm plate; Thick plate definition: Thickness greater than 6mm plate. Except for North America, other countries and regions are defined as such, and North America defines thick plates as plates with thickness greater than 0.25 inches (6.35 mm). However, in the iron and steel industry, there is really a term “middle plateâ€. Their definition is: thin plates with thickness ≤ 3.0mm, plates with thickness> 3.0mm~ ≤ 20.0mm are medium plates, plates with thickness > 20.0mm~ ≤ 40.0mm. Thick plates, plates with a thickness greater than 40.0 mm are special thick plates.
It is suggested that the term “plate†should be removed to align with international practice and not to create confusion for standard formulation. We should not use this term anymore. If we think it is necessary to add this term, we should give clear explanations and definitions in the standard.
Wheels and wheels About the year before 2010, China referred to automotive aluminum wheels as hubs. It was right. Since 2010, it has changed the name of wheels. It is also correct. It is internationally known as the reason why wheels are renamed as wheels. With international standards, it is easier for international contacts and international trade. China is the world’s largest producer and exporter of aluminum wheels for automobiles and aluminum wheels for motorcycles. In 2014, the production capacity of aluminum wheels for automobiles in China exceeded 200 million pieces/year, and the output was approximately 160 million pieces. The export volume accounted for 51.5%. More than 1600 kt of aluminum alloy wheels are consumed, and about 1300 export manufacturers. China should export more aluminum wheels. The goal should be that exports account for about 80% of production. According to the data from the China Association of Automobile Manufacturers, in 2014, the production capacity of Chinese aluminum motorcycle wheels was about 100 million pieces/a, and the output was about 68,000k pieces, and the export volume accounted for about 55%.
Friction stir welding and friction stir welding (FSW)
FSW (Friction Stirwelding) was invented by the British Welding Institute (TWI) in the early 1990s. In 1999, the Norwegian company Sapa Aluminum Corporation carried out commercial welding for the first time. Now this method has become more aluminum and aluminum alloys. Advanced welding technology, China has completely mastered this technology and its equipment manufacturing technology. At present, there are two translation methods for FSW in China, one for friction stir welding and the other for friction stir welding. The former is correct, the latter is wrong, regardless of English grammar and habits, or the working principle of this method. It is wrong to say that friction stir welding is used on all occasions. It is hoped that it will be corrected. The official publication should not use the term “friction stir weldingâ€.
Compared with other current aluminum alloy welding processes, the main advantages of friction stir welding are: the welding temperature does not reach the melting point of aluminum and aluminum alloy, usually not higher than 510 °C, will not melt, but is greatly softened, so it can follow the pointer. “Flowâ€, the weld has a recrystallized structure that is more refined than the base metal. The weld is almost in the same plane as the base metal. Their mechanical properties are almost equal; the weld seam can be straight or other shapes, for cracks. Sensitive alloys can also be welded without special measures; there is no need for filler metal and shielding gas at a lower cost than conventional processes; there is no need for openings and pre-weld treatment; the welding speed is higher than that of MIG. Welding distortion is only one-twelfth that of the MIG method; all deformed aluminum alloys and cast aluminum alloys can be welded, and dissimilar metals such as copper and aluminum can be welded; heat-affected properties are higher than those of fusion welding; and conventional fusion Compared with the welding method, this method has a low welding temperature, little deformation, and no solidification cracks. It is a modern, better process for welding aluminum alloys, and can be easily welded to those that are difficult to weld. Cracked ultra-hard aluminum alloys and aluminum-lithium alloys, etc.; can weld single-side up to 75mm thick, double-sided welding 150mm workpieces, is an environmentally friendly welding process, no gas, no arc, no emission of gas; after welding No correction required; low inspection cost; high degree of automation; repeatable production; China should promote the application of friction stir welding to the extent possible.
Extrusion of round ingots and billets
Billet should be translated as round ingots, extruded round ingots, can be referred to as round ingots, but can not be translated as round rods or cast rods, because the rod's English is bar or rod. The rod is a semi-finished product, and the ingot is the raw material of the rod. The cylindrical ingots used for extrusion are said to be rods or rods, which are easily mistaken for bar materials and are semi-finished products. In the early years, a Chinese company wrote a bar that simply processed circular rods and exported rods to When re-melting ingots in the international market, fraudulent export tax rebates cause adverse effects in the international market.
Any aluminum product called "stick" must be ≥ 70% regardless of the appearance, otherwise it cannot eliminate the casting structure and cannot be regarded as a "stick". Even if the deformation rate reaches 50%, it should be regarded as an ingot, not a bar. In China, casting ingots is said to have originated from the construction and production of aluminum profiles in Guangdong Province in the mid-1980s. It is now difficult to avoid using the term "cast rod" in publications.
About the name of the foreign aluminum company The principle that should be respected when it comes to the translation of a foreign aluminum processing company is that if it has been registered with the relevant industrial and commercial department in China, the name of the registered trademark shall prevail, such as the registered name of Novelis Aluminum Corporation. Bellis Aluminum, Alcoa's registered name is Alcoa. However, I also have different opinions, such as UACJ, the registered name in China is “Nihon Aluminum Corporationâ€. This is Japanese. If this name is used, many people may not know that this is a What company, so we should use Japan United Aluminum Corporation; Hazellet company, according to the English standard pronunciation should be translated as "Hazlet" company, but he felt that "black" in Chinese is a bit unlucky, so registered as "Ha Zelit Company." If it is not registered yet, the translated name must be close to the pronunciation as well as auspicious and far-reaching, as Aleris translates as “Aili Aluminum Companyâ€. Respect for history, such as Ford Motor Co., can be translated into Ford Motor Co., but it is a former auto company that entered China. At that time, it was known as the Ford Motor Company.
"Corporation" is Japanese, and Chinese is a stock company. Actually, "company" is a transliteration of "society". It is the result of our study in Japanese. With the company's well-known term, there is no need to introduce "plant type." Club" is the foreign name.
In addition, do not use the term “noise†in everyday communication and articles and reports, and apply “noiseâ€, which is regulated by national standards. The extruder's "Container" should not be translated as "Sheng Tung".
