本文就绝热板的制作工艺及其性能,绝热板帽口(按原设计尺寸)浇注镇静钢的试验及其效果作了介绍。绝热板帽口在生产中推广应用,基本解决了由于原设计热帽口较小钢锭头部中心收缩过深造成的缩孔废品,钢锭头部炭的偏析获得了改善,钢锭成坯率提高了1.88%。使用绝热板帽口配以绝热盖板的成本较发热板帽口加发热剂的成本有所下降。最后,对今后帽口设计的改进提出了设想。
In this paper, the production process of insulation panels and their performance, insulation plate hat (according to the original design size) of cast steel test and its effect were introduced. Insulation plate hat in the production of popularization and application, the basic solution to the original design of the hot hat smaller head shrinkage caused by the center of the shrinkage cavity shrinkage, segregation of the head of the ingot has been improved, ingot billet increased 1.88%. The cost of using insulated cap hatch with heat-insulated cover plate is lower than the cost of heating plate cap plus heating agent. Finally, the idea of improving the design of hats is put forward.
