The purpose of the vacuum system - for metallurgical industry

with the continuous development of vacuum technology, vacuum technology has been applied in some industrial fields, and then extended to metallurgical technology, the vacuum metallurgy. Vacuum technology innovation for metallurgy, construction and secondary metallurgy furnace productivity made an important contribution. Vacuum system satisfy certain requirements, in order to save energy of high quality steel production and reliably guarantee the vacuum degree required. Small make up plan to use this article to illustrates the application of vacuum system in metallurgical industry. I hope the following content to be of service.

'metallurgical' is extracted from mineral metal or metal compounds, and use all kinds of processing methods will be the process of metal forming has certain properties of metal materials. Metallurgical industry development has a long history. From the Stone Age to the Bronze Age that followed, and then to the establishment and development of modern metallurgy industry, people continuously explore various ways to reduce atmospheric environment and the influence of impurities of metal smelting, but it can not fundamentally solve the problem, until the emergence of vacuum metallurgy technology, has been made on the fundamental breakthrough in metallurgical technology.

use vacuum system to improve the efficiency of metallurgy.

when the vacuum technology is introduced into the metallurgical process, the surface of various materials research, which makes the research and production of vacuum metallurgy field more widely. Almost all of the metallurgical process can be added to the vacuum technology and further improvement. Since the limitation of equipment and the consideration, mature research areas include: vacuum degassing, vacuum casting, vacuum heat treatment, vacuum welding, vacuum reduction and vacuum surface treatment, etc. Here are several common vacuum are briefly introduced. System in the main application field for metallurgy.

1, vacuum degassing

vacuum degassing is mainly used in steel processing. Molten steel under atmospheric pressure usually contains the harmful gas, which can lead to defects in ingot and degrade the performance of the steel.

in order to deal with a lot of molten steel, the researchers put forward the ascension vacuum and vacuum treatment cycles. Circulation vacuum processing method combines the vacuum refining and steel circulation flow together, and has been widely used in the steel plant all over the world.

2, vacuum induction melting

vacuum induction melting is widely used in various kinds of metal materials, smelting such as heat resistant steel, bearing steel, iron, nickel alloy and stainless steel. This method can significantly improve the breaking strength of the material, temperature toughness and resistance to oxidation, therefore has been widely used steel manufacturers.

the technology is put forward and application of relatively early on. Later, with the development of large vacuum equipment, the technology is also hoping for large-scale development. At present, may be charging, achieve continuous or semi-continuous casting process such as vacuum induction melting, and won't damage the vacuum in the melting process.

3, vacuum arc melting

vacuum arc melting is a kind of the method of using arc in a vacuum heating molten metal. The vacuum melting process is very simple, but the preparation of electrodes is very important. Processed into electrode materials will be used, the chemical composition of qualified, good electrical conductivity. In addition, the vacuum metallurgy and other application fields, such as vacuum distillation, vacuum melting, etc.

well, today that's all for the application of vacuum system in metallurgical industry, will be publishing more articles, please attention!
