120mm×285mm断面高效管式结晶器的研制与应用

Research and Application of High Effective Tube Mould (120mm×285mm)

莱钢炼钢厂应用高冷却强度结晶器技术,将原组合铜板式断面结晶器改造为高效管式结晶器。使用证明,高效管式结晶器实现了高拉速生产,铸坯表面质量合格率达到100%,提高了铸机生产作业率,铜管通钢量达到6000t,吨钢成本降低2～3元。

The mould technology with high cooling intensity is adopted in the steel-making plant of Laigang to transform general built-up mould to high effective tube mould. By using high effective mould, the high withdraw speed producing is realized, the surface quality of billet is 100%, the casting rate is improved, the steel passing copper tube reaches to 6000 tons and the cost of every one ton steel is reduced by 2-3 Yuan.
