The process that continuous casting process produces alloy steel billets can improve the yield of alloy steel and reduce the loss of alloy elements ( some alloys contain precious metal elements). Therefore, less cutting head can reduce the production cost, and because the quality of the casting billet produced by…
The tundish as a key device in the meltshop has some actual problems especially in billet continuous casting process as follows: (1) The inner cavity shape of tundish is unreasonable. The shape of the inner cavity influences the flow of molten steel in the tundish the residence time is short,…
Key words: High-efficiency, fine slag, crushing equipment,slag The complex structure of steel slag is a combination of slag and iron, which are intermingled with each other. Under the premise of ensuring the grade of magnetically selected slag steel (slag steel particles), steel slag is crushed to 75mm after magnetic separation,…
1.Nuclear service stainless steel Nuclear service stainless steel is used in nuclear power plants and contains a large number of radioactive substances in contact with the core coolant austenitic stainless steel. Because of the high dose of neutron irradiation, so the nuclear service stainless steel has the bottom of the…
Keywords: tundish; electromagnetic induction heating; The tundish, as an important convergence point of steelmaking from intermittent operation to continuous operation, plays a very important role in process compliance, steel purification and improvement of billet quality. In recent years, the practice of continuous casting technology development also shows that the constant…
Support rolls refer to the rolls that can increase the rigidity of the work rolls and directly or indirectly bear the rolling load, which is an important part to prevent the work rolls from flexural deformation and affect the quality of plate shape. Support roll body to withstand a lot…
1.In 2023, the high-end development of special steel industry products accelerated, and the industry pattern realised significant adjustment. China Special Steel Enterprise Association statistics show that in 2023, China’s crude steel output of special steel increased slightly by 1.7% year-on-year, of which the output of special quality alloy steel rose…
A new type of tundish adopts a double shell inclusion and cover with vacuum insulation function, and is supplemented by anti-oxidation coating heat insulation technology and permanent layer castable with low thermal conductivity. The original intention of its research and development is to use the principle of vacuum insulation to…
Today (February 2) is 23 in lunar 12th month, the northern traditional XIAO NIAN. Most of the southern areas of our country XIAO NIAN is on the 24th. There is a week to go before the New Year, let’s welcome full of blessings. Little New Year is the prelude to Major…
The World Steel Association released the world 2023 crude steel data on January 25. Total world crude steel production was 1,888.2 Mt in 2023. Crude steel production in India and South Africa increased by more than 10% compared with 2022, while crude steel production in Mexico, France, Poland, Belgium, Pakistan,…
