我厂生产的水平连铸关键零件结晶器铜套,规格有90、120、130、150、160等。结晶器铜套的关键是锥方孔加工,锥方孔的精度、表面粗糙度、形位公差要求很高,国外一般采用电解加工、冷挤压或精密仿形铣等方法;而我厂没有这些先进设备,我们采用普通机床和专用工装、百分表等进行精心加工,使其完全达到了设计要求,其表面粗糙度小于西德样品。在冶金部组织的水平连铸鉴定会上,通过了鉴定,填补了结晶器铜套生产的空白。
I plant the level of the main parts of the continuous casting mold copper sleeve, specifications are 90,120,130,150,160 and so on. Mold copper sleeve is the key to the cone square hole processing, cone square hole accuracy, surface roughness, high tolerance requirements of shape, the general use of electrolytic machining abroad, cold extrusion or precision profile milling and other methods; These advanced equipment, we use ordinary machine tools and special tooling, dial indicator and other carefully processed to fully meet the design requirements, the surface roughness less than West Germany samples. Metallurgical department in the organization of the level of continuous casting appraisal meeting, passed the appraisal, to fill the mold copper blank production.
