连续铸钢开始于立式连铸机。这种连铸机的生产能力不能满足要求,因为由于坑深,并由此引起的铸坯内部静压力使铸速受到限制,而且要管理操纵大量的辐道设备。进而发展为立弯式连铸机,其优点是,这种连铸机由于其设备高度较小,较易于在现有钢铁厂建设,而且板坯长度不再受限制。然而,就在这种情况下静压力仍妨碍了拉速的提高。弧形和椭圆形连铸机有相当低的设备高度。它最初设计是使连铸机较易于在现有炼钢厂内装设,同时在这种连铸机的设备高度上铸坯的静压力较小,而且易于控制。拉速 Continuous casting begins with vertical caster. The production capacity of this kind of caster can not meet the requirements because of the limitation of casting speed due to the deep pit and the resulting static pressure inside the slab, and the management and operation of a large number of spokes devices. The further development of the vertical caster has the advantage that the caster is easier to build at the existing steelworks due to its smaller equipment and the slab length is no longer limited. However, in this case static pressure still hinders the increase of pulling speed. Arc and oval caster machines have considerably lower equipment heights. It was originally designed to make continuous caster easier to set up in existing steel mills and at the equipment level of this continuous caster the slab has less static pressure and is easier to control.
