It is quite important to operate a new induction furnace correctly, that could affect the service life of the induction furnace. The new furnace should be continuously smelted as much as possible to avoid thermal shock damage caused by intermittent melting and hot and cold, and generally should be continuously…
Inaugural Ceremony of the Adama Steel Expansion Project, to take place on March 8, 2022, at 3:00 p.m. in the Adama Steel Factory Compound. The prime minister Mr.Abiy Ahmed of Ethiopia attended this huge ceremony. This expansion project is capacity of 180,000 TPA rolling mill in Ethiopia, finish products rebar…
According to incomplete statistics, 2021 global new steel production capacity (excluding China) nearly 90 million tons mainly concentrated in Asia, Europe, including new long steel capacity of 14.4 million tons , new plate capacity of 14.02 million tons, new crude steel production capacity of about 53.27 million tons, new semi-finished…
Solidification of continuous casting billets will release much heat that divided three parts: superheat of steel: the heat released from the cooling of the steel from the pouring temperature to the solidification temperature; latent heat of solidification: the heat released from the cooling of the steel from the liquid phase temperature…
Why is nitrogen added to the steelmaking process? The effect of nitrogen on steel is mainly in the area of heat treatment and process properties. Both nitrogen and carbon can be incorporated into iron as an interstitial linkage to iron, and unlike carbon, nitrogen is a very good austenitic stabilizing…
DC EAF and AC EAF steelmaking process has different features The magnetic field force generated by the energized in DC EAF has strong stirring ability than the AC EAF, and DC EAF decarburization, dephosphorization, degassing reaction is faster than the AC EAF, more conducive to the operation. Because the desulfurization…
For electric furnace steelmaking process, there are 20 kinds of scrap able to be used. Carbon scrap: All kinds of carbon scrap shall not be mixed with alloy scrap, plate thickness above 2mm, wire diameter above 4mm, single weight above 0.25kg including edge scrap, cast steel parts, scrap machine parts,…
Clean steel is a steel with very strict requirements for the content of impurity elements in steel, generally requiring S,P mass fraction of less than 0.01%, and the content of hydrogen, oxygen and low melting point metals also have strict requirements. China’s current production of clean steel mainly uses the…
Longitudinal cracks on the surface of continuous casting billets leave delamination defects on the rolled sheet, which can cause breakout and waste billets.The research points out that the longitudinal cracks originate from the unevenness of the thickness of the primary billet shell on the bending moon surface of mould. The tensile…
Carbon steel ice skates are generally used by beginners at the entry level, the ice knife of different quality mainly depends on the carbon content, such as spring steel. Although the hardness of ice knives used in the same project reaches the same standard, due to different grades of steel,…
