高速浇铸对提高生产率、生产热态板坯及节约连铸能耗,是非常重要的。日本钢管公司,开发了新型连铸保护渣,实现了高速浇铸,从而保证了连铸板坯直接热轧工艺的进行。开发结果,实现了2.O米/分以上的高速浇铸(最大达2.5米/分)。使用高速浇铸保护渣必须满足下述条件: 1.保护渣耗量≥0.3公斤/米。(Vc≥2.0米/分,低粘度、低熔点)。 High-speed casting is very important for increasing productivity, producing hot slab and saving energy for continuous casting. Nippon Steel Pipe Co., Ltd. has developed a new type of continuous casting mold powder to achieve high-speed casting, thus ensuring continuous hot-rolling continuous casting slab process. Development results, to achieve 2.O m / min high-speed casting (up to 2.5 m / min). The use of high-speed mold powder must meet the following conditions: 1 flux consumption ≥ 0.3 kg / m. (Vc ≥ 2.0 m / min, low viscosity, low melting point).
