研究似φ450mm 15CrMoG圆管坯连铸二冷工艺,并建立了二冷工艺模型。产品试制情况表明,制定的二冷工艺合理,生产的15CrMoG管坯质量优良,满足标准及用户使用要求。
Study similar to φ450mm 15CrMoG round tube billet secondary cooling process, and established a second cooling process model. Trial production of the product shows that the development of the second cold process is reasonable, the production of 15CrMoG tube quality, to meet the standards and user requirements.
