在浇铸镇静钢时,有时在钢锭帽部发生悬挂。造成钢锭横裂。悬挂的主要原因是钢锭帽部涂层被烧损。西西伯利亚钢铁公司设计并试验了一种用作保温帽涂层的绝热剂,它含有石煤溶液、耐火粘土和亚硫酸盐液,在浇铸11.5吨重锭时,涂层厚度为10毫米。在保温帽浇满钢水后,钢水和内衬界面上长时间保持着1350—1250℃高温。这种绝热剂的熔点为1400℃。由该利组成的涂层将能使接触钢水的部分软化而产生塑性形变。该剂在起润滑作用的同时还能预防钢水在凝固过程中的收缩受阻并使钢锭不产生悬挂。由于在保
In the casting of cast steel, sometimes hanging in the ingot cap. Resulting in cross-cracking steel ingot. The main reason for hanging is that the coating of the ingot cap is burned. West Siberian Steel designed and tested a thermal insulation coating used as a thermal insulation coating, which contains stone coal solution, refractory clay and sulphite and has a coating thickness of 10 millimeters when casting 11.5 ton heavy ingots. After the insulation cap is filled with molten steel, the molten steel and the lining interface maintain a high temperature of 1350-1250 ° C for a long time. This heat insulator has a melting point of 1400 ° C. The coating consisting of this material will soften the part that touches the molten steel and cause plastic deformation. The agent can prevent the shrinkage of the molten steel during the solidification process and prevent the steel ingot from hanging while functioning as a lubricant. Due to Paul
