立弯型连铸机的直结晶器及二冷区的直立段为钢水凝固及带液芯的铸坯凝固提供了一个全方位对称的冷却环境,是保证结晶器及二冷段同高度铸坯的热流密度均匀的根本条件,是浇铸高质量铸坯的重要基础。立弯型连铸机使铸坯的重力最大限度地替代拉矫机的拉力,改变了铸坯的受力状态,减少铸坯承受的外力(拉坯力),对提高连铸坯的质量有着重要的作用。
Vertical bending machine of vertical bending continuous casting machine and upright section of second cooling zone provide solidification of molten steel and solidification of slab with liquid core to provide an omnidirectional symmetrical cooling environment to ensure the same height of slab The basic conditions of uniform heat flux density, is an important basis for casting high-quality slab. Vertical bending continuous casting machine to make the slab gravity to maximize the tension instead of tension straightening machine, changing the stress state of the slab, slab to reduce the external force (pull force), to improve the quality of slab has Important role.
