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,…
What is the major changes of 2023 global steel industry? From the OECD report found 2023 global steel performances and regional trends. Crude steel capacity uping According to a report released by the OECD, global crude steel capacity reached 2,498.6 million tonnes by the end of 2023, an increase of…
Many cracks on the wire surface are caused by the transverse and longitudinal cracks of billets and rolling process, that can reduce the generation of cracks on wire rod surface through the control the quality of raw materials and proper rolling operation procedure. 1 Billet surface longitudinal cracks, transverse cracks…
In production operation, some methods are useful for increasing the life of roller ring, if the operators pay attention on need to know correct To select suitable roller rings The hardness and wear resistance of the roll ring comes from tungsten carbide, while the toughness and strength depend on the…
