介绍了换水口专用保护渣的选择和试验情况,结果表明试验渣具有较合理的黏度和熔化特性,能均匀冷却铸坯和保证润滑,预防铸坯粘结,减轻结疤,避免来不及熔化的保护渣卷入钢液形成铸坯内的大颗粒夹杂物;通过专用渣的使用,废坯减少了100.2 t/月,产生了较好的经济效益。 The selection and test conditions of the special fluxes for water changers are introduced. The results show that the test slag possesses reasonable viscosity and melting characteristics, which can uniformly cool the slabs and ensure the lubrication, prevent the slab from sticking, reduce the scars and avoid too late the melting protection Slag into the molten steel to form large particles in the slab inclusions; through the use of special slag, reducing the waste 100.2 t / month, resulting in better economic benefits.
