The rate of nitrogen desorption is faster than that of deoxidation as sulphur content is low, while deoxidation rate faster than denitrogenation rate for high sulphur content; ( 3) the rates of decarburization and deoxidation are not affected by sulphur content in steel. 而当硫含量较高时,脱氧速率大于脱氮速率.(3)真空碳脱氧过程中,脱碳、脱氧速率与硫含量关系不大。
The decarburization speeds up, as the Ar blow rate increases, and the influence of argon flow rate on decarburization is greater in the low carbon zone. 随底吹氩气流量的增加,脱碳速度加大,此种作用在低碳区影响尤为明显。
Reducing heating temperature and residual oxygen percentage in the furnace, shortening time in the furnace, increasing cooling rate of γ′+ α duplex-phase range after rolling can reduce the ferrite decarburization. 降低加热温度和炉内残氧量、缩短在炉时间、提高轧后两相区冷却速度可明显降低钢的表面脱碳。
