Development of EAF Steelmaking
The development of EAF steelmaking can be divided into three stages。From the beginning of small EAF specialized in smelting alloy steel, to the later change to large EAF for smelting alloy steel and plain carbon steel, until the recent ultra-high power large (AC, DC) EAF only used as scrap melting equipment.

Common Steel Rolling Method
From the metallurgical point of view, the boundary between hot rolling and cold rolling should be from the metal recrystallization temperature is generally between 450℃ to 600℃, even if it is higher than 450℃ to 600℃, it also belongs to the range of hot rolling. The rolling temperature is less than 450 to 6 Baidu and the rolling is in the range of cold rolling. In the rolling steel production, the...

Control of Rolling Mill Rolling
Controlling the rolling of the rolling mill can strengthen and toughen the steel. The essence is to control the metallurgical process (such as austenite in recrystallization, alloying elements and carbon and nitride solid solution and precipitation, phase transformation, work hardening, texture, etc.) of the steel during the whole rolling process by adjusting various rolling process parameters (su...
