JISCO Stainless Steel Branch successfully realized multi-furnace continuous casting of high manganese non-magnetic steel
Recently, the Stainless Steel Branch successfully realized the continuous casting of 20Mn23AIV high manganese non-magnetic steel in multiple furnaces, breaking the history of single furnace casting of this steel.
High-manganese non-magnetic steel is a high-end product made by JISCO, which is mainly used in key parts of transformer anti-magnetic. The manganese content of this steel grade is as high as 25%, which is 20 times that of conventional steel grades, and the aluminum content is as high as 2.0%, which is 260 times that of conventional steel grades. In the continuous casting and pouring process, it is easy to cause the mold slag to denature and deteriorate the performance. In addition, the steel grade has high temperature and low strength, and breakout accidents are extremely likely to occur. During the production process of some steel mills, the rate of steel breakout was extremely high, and they were eventually forced to stop development, which also made many steel mills discouraged and discouraged.
JISCO stainless steel successfully produced 20Mn23AIV high-strength non-magnetic steel using a continuous casting process in 2018, but due to the unstable casting process, single furnace casting has been adopted. The management and technical personnel of the stainless steel branch are unwilling to the status quo and breakthrough themselves. Through a large amount of data analysis and on-site tracking, through measures such as optimizing parameters and refining the process flow, the stability of the pouring process has been improved. After many on-site verifications, they finally successfully realized 20Mn23AIV The multi-furnace continuous casting of high manganese non-magnetic steel has brought the production of high manganese and high aluminum steel to a new level.
