摘要: 針對包晶鋼的凝固特性,研發了高堿度、高結晶速率、低結晶溫度及低熱流密度保護渣,并在寶鋼3^#連鑄機上進行了試驗研究.現場試驗四個澆次的結果表明,使用改進渣的試驗流鑄坯無縱裂發生,而使用原渣的對比流鑄坯裂紋率達到5%.優化保護渣有效防止了鑄坯表面縱裂的發生.

Abstract: According to the solidified characteristic of peritectic steel for wide and thick slabs, mold fluxes with high basicity, high crystallization rate, low crystallization temperature and low heat flux density were developed and experimentally studied on 3^# Caster at BaoSteel. The trial results of 4 casting times showed that experimental strands produced with the developed mold fluxes had not surface longitudinal cracks, but the surface longitudinal crack ratio of strands produced with original mold fluxes was 5%. The developed mold fluxes can prevent surface longitudinal cracks in wide and thick slabs effectively.
