大方坯连铸机关键技术

The key technology in bloom caster

论述了大方坯连铸机关键技术,其中包括辊列设计中机型选定,结晶器长度、铸机基本圆弧半径的确定、各矫直点的矫直半径、冶金长度、几何尺寸等的设计及电磁搅拌、结晶器液压振动、二冷水控制、具有动态轻压下功能的拉矫机组等,阐述了大方坯连铸机的国产化情况,为新建大方坯连铸机的技术选配和老的大方坯的连铸机的改造提供了依据。

The article discussed the main techniques of the bloom caster which include the machine type selection, the mold length, the segment radius, the straightening radius, the metallurgical length, EMS, the hydraulic mold vibration, second cooling water control and the soft-reduction. A description of the revamping of bloom casters is also presented in this article which is not only helpful for the machine selection when build- ing new bloom casters, but also helpful for the rebuilding of existing bloom casters.
