我公司二钢厂一直采用敞口模化学封顶工艺生产沸腾钢。这种工艺生产的钢锭,热轧后常常产生一些缺陷,致使废品量增多。为此,进行了瓶口模试验。为弄清目前生产工艺下瓶口锭内部的结构、成分偏析、夹杂物状况等,我们解剖了瓶口锭,并对瓶口、敞口锭板材进行了对比分析,据此说明与浇注工艺的关系。 My company two steel mills have been using open-top chemical crown production of boiling steel. Steel ingots produced by this process often have some defects after hot rolling, resulting in an increase in the amount of scrap. To this end, a bottle die test. In order to understand the structure, composition segregation and inclusions in the bottle spindles under the current production process, we dissected the bottle spindles and compared the bottle spouts with the open ingot plates. relationship.
