Abstract With the development of the alloysteel and continuous casting technology at home and broad in recent years,the authors put forward some suggestions for the alloy steel bar production by using EAF steelmaking process.And the practicability of matching eight kinds of EAF with continuous casters and rolling mills to produce modern bar is also discussed.The popular trend in the world in EAF steel manufacture process (1 EAF→1 refining furnace→1 continuous caster→1 main rolling mill) is that the capacity of over 100 tons EAF is widely used.But this is too high,and it will need too many cast strands of the continuous caster on the one hand and too bigger form of section on the other,which will impose difficulty on providing the suitable rolling mill to match with it.As a result,this EAF suits the plate plant better rather than alloy bar plant.Based on the current fact that the special steel plant uses EAF to produce machinery and the products are more used in the automobile industry,5090 tons EAF is the reasonable choice to produce bar steel, and the production scale should be limited to 40×104×90×104 t/a.
