热水器内胆用热轧酸洗搪瓷钢的研制

Development of the Hot-rolled and Pickled Enamel Steel for Water Heater Tank

针对搪瓷用钢向着经济性、耐久性方向发展的趋势,山西太钢不锈钢股份有限公司研制了热轧酸洗搪瓷钢T330TCG热轧带钢。介绍了其化学成分设计和热连轧工艺,并对其组织和性能进行了调控。生产实践表明,试制带钢的组织为铁素体+少量珠光体,拉伸性能和冷弯性能优良,且具有良好的搪瓷性、焊接性及耐压性,能够满足用户的加工使用要求。

In view of the development trend of enamel steel toward economy and durability, the hot rolled and pickledenamel steel strip was developed in Shanxi Taigang Stainless Steel Co., Ltd. Its chemical compositions and hot tandemrolling process were designed, and the microstructure and properties were also controlled. The practice showed that themicrostructure of the tested strip is ferrite anda small amount of pearlite, excellent tensile properties and cold bendingproperties, and good enamel, weldingandpressure performance, which can meet the user＇s requirements.
