日立造船公司技术研究所等单位研制的双辊式薄板坯连铸机,在原来1,2号试验机的基础上,3号试验机已制造成功。这种连铸机的结构和控制都比较简单,结晶器由两个水冷的铜辊构成,中间包直接设置在结晶器上方,由马达带动铜辊结晶器和拉坯辊,由控制系统使两辊同步转动。铸坯从结晶器拉出时,呈半凝固状态,再经导卫带支撑,冷却成坯。 Hitachi Shipbuilding Technology Research Institute and other units developed by the two-roll thin slab caster, on the basis of the original 1,2 test machine, No. 3 test machine has been manufactured successfully. This continuous casting machine structure and control are relatively simple, the mold consists of two water-cooled copper roller tundish set directly above the mold by the motor driven copper roller mold and casting roller control system so that the two Rolls rotate synchronously. Billet pulled out from the mold, was semi-solidified state, and then guided by the belt support, cooling into blanks.
