摘要
武钢新3#铸机在浇注过程中存在结晶器锥度不稳定、板坯三角区裂纹等主要问题。在分析足辊工作原理的基础上,对足辊间距、结晶器下口宽度、坯壳鼓肚量等参数进行迭代计算,使不同断面条件下的结晶器足辊安装工艺参数最优化。生产实践表明,结晶器倒锥度异常变化减少50%,铸坯特裂发生率减少1/3。
The unstable change of mould taper during casting and the trigonal area crack of slab are main problems of new No.3 caster. The installing process parameters of mould foot-roller with different section sizes are optimized by means of parameter iteration calculation for foot-roller gap, width of the mould outlet, slab shell bulge, etc, on the basis of analyzing working principle of foot-roller. The practice shows that the abnormal change of mould reverse taper is decreased by 50% and trigonal area crack of slab is decreased by 1/3.
