Abstract

The flow sheet of production for carbon and alloy structural steel

mooring chain steel

bearing steel

spring steel and HSLA steel at Huaigang is 80 t converter-90 t LF-100 t RH-wire feeding-Φ 380 ~Φ600 mm round bloom CC process. With 40 t tundish

auto control of liquid level in curved tube type mold

water spraying + fine spraying secondary cooling

M-EMS + F-EMS electromagnetic stirring and casting speed 0.3 ~0.8 m/min

the annual production capacity of round casting bloom is L 2 million ton. The characteristics of equipment and relative process optimum including tundish

mold

electromagnetic stirring and secondary water cooling and the improvement of round bloom metallurgical quality are presented in this article.
