一、水平连续铸钢存在的问题水平连续铸钢的优点很多,但由于其中间包与结晶器直接连接这一特点,要在工业生产上得到应用,还必须解决以下几个问题: ①中间包与结晶器接合部位的耐火材料要求非常严格(一般难以达到); ②为了防止铸坯与结晶器粘结,采用立式和弧形连铸机上所用的振动方法是困难的,必须研究替代的机构; ③由于结晶器内的润滑剂从外部供应十分困难:特别是不锈钢铸坯与结晶器的摩擦阻力较大,因此,要研究独特的润滑方式。
First, the level of continuous casting problems Horizontal continuous casting steel has many advantages, but because of its tundish and mold directly connected to this feature, to be applied in industrial production, but also must solve the following problems: ① tundish And the refractory parts of the junction with the mold is very strict (generally difficult to achieve); ② In order to prevent the slab and mold bonding, the use of vertical and arc caster vibration method used is difficult, we must study alternative mechanisms ; ③ Since the lubricant in the mold is very difficult to supply from the outside: in particular, the frictional resistance between the stainless steel slab and the mold is large. Therefore, it is necessary to study the unique lubrication method.
