摘要
根据攀钢2号板坯连铸的工艺特点，在分析了高速连铸对保护渣性能要求的基础上，研究开发出了适应高拉速浇注的连铸保护渣，工业试验结果表明，研究开发的XIZ-DT高拉速用连铸保护渣，在拉速≥1．75m／min时，结晶器内熔化状况良好，保护渣消耗量0．38-0．42kg／t，所浇铸坯表面质量良好，铸坯表面无清理率98．70％，能够满足攀钢2号板坯高速浇注的需求。
According to the process characteristics of No.2 Slab Caster, the mould fluxes were developed for NO.2 Slab continuous casting in Panzhihua Iron ＆Steel Co. Ltd. （PISCO） by analyzing the requirement of high speed continuous casting mould fluxes properties. The plant trials results showed that XIZ-DT mould fluxes has good smelting property and the mould fluxes consumption is 0.38-0.42kg/t, and non-descaling ratio of slab surface was up more than 1.75m/min. The mould fluxes can meet the demand of to 98.70% under the casting speed NO.2 high speed slab caster.
