合钢第二炼钢厂,在转炉炼钢过程中,积极应用SiC增碳剂增碳,效果显著.该厂于1991年开始在转炉钢过程中,试用SiC增碳剂替代生铁增碳,经过5年多时间的试用,最后确定增碳剂成分为C(55±1%)、SiC(25±5%)、P(≤0.050%)和S(≤0.05%),粒度为16mm.增碳方法,一为钢包增碳,因为炉后增碳是转炉炼钢不可缺少的工艺技术之一,可使用SiC增碳剂直接用于倒包或出钢过程包中增碳;二是当铁水硫高(S≥0.50%)、硅低(SiC0.60%)时,在兑铁水时加入SiC增碳剂1至2kg/t,可以提高铁水中S的活度,开吹后由SiC氧化反应,促使碳熔化,缩
In the second steelmaking plant of Hegang Iron and Steel Co., Ltd., carbon sequestration was actively applied to increase the carbon content in converter steelmaking process, and the plant started to use carbonation agent instead of pig iron to increase carbon during the process of converter steel starting in 1991, After more than five years of trial, the composition of the carbon remover was determined to be C (55 ± 1%), SiC (25 ± 5%), P (≦ 0.050%) and S Method, a ladle carbon, because after the furnace is carbon converter is an indispensable steelmaking technology, the use of carbon agent can be used directly in the process of inverted or tapping process of carbon; Second, when the hot metal sulfur (S≥0.50%) and low silicon (SiC0.60%), adding 1 to 2 kg / t of SiC recarburizing agent to the hot metal can increase the activity of S in the molten iron, Promote carbon melting, shrinking
