摘要

通过180 t顶底复吹转炉+LF成分控制及Ti微合金化

连铸成230 mm板坯经1200-1250℃加热

控制轧制后快速冷却至500～700℃卷取等工艺措施

山西太钢不锈钢公司成功开发了热水器内胆用热轧搪瓷钢（/%:≤0.14C

≤0.06Si

≤1.20Mn

≤0.030P

≤0.025S

≤0.10Ti）2 mm热轧钢板。结果表明

热轧钢板经850℃10 min模拟搪烧后仍具有较高的强度（Rm 366 MPa）以及良好的成型性能;热轧态晶粒均匀细小

搪烧后晶粒尺寸无明显变化

且有大量第二相粒子弥散析出;工业生产的搪瓷钢经单面搪瓷后表现出良好的抗鳞爆性能;能够满足制作热水器内胆的各项应用要求。

Abstract

With the process measures including composition controlling by 180 t LD with top-bottom blowing and Ti microalloying by LF

continuous casting into 230 mm slabs and heating at 1200 ~ 1250℃

rapid cooling after controlled rolling

coiling at 500 ~700 ℃

Shanxi Taigang Stainless Steel Co Ltd has successfully developed 2 mm hot-rolled enamel steel sheet for water heater tank (/% : ≤0.14C

≤1.20Mn. ≤0.030P

≤0.025S

≤0.l0Ti). The results show that the steel sheet after simulated enamelling at 850 ℃ for 10 min still has high strength (Rm 366 MPa) and good formability ；the hot-rolled grain is uniform and fine

and there is no obvious change in grain size after enamel

and there are a large number of second phase particles dispersed precipitation ； for commercial produced enamel steel after single-sided enamel

it shows good scale explosion resistance and can meet the application requirements of making water heater tank.
