Converter tapping hole with long service life
The invention belongs to the technical field of iron and steel smelting, and particularly relates to a converter tapping hole with long service life. A sleeve brick of the tapping hole is an MT-18 magnesia carbon refractory brick added with an antioxidant; and a filler at the tapping hole is a mixture of fused magnesite, SiO2 micropowder, Cr2O3 powder, a water reducing agent PS10 and a suspendingagent. Aiming at the situation and problems of a tapping hole used on site at present, the material of the converter tapping hole is improved and the component proportioning scheme of a filling material of the tapping hole is optimized in the invention, so the comprehensive service life of the converter tapping hole can be effectively prolonged and the converter tapping hole is more convenient toserve for production.
本发明属于钢铁冶炼技术领域，具体涉及一种长寿命的转炉出钢口，所述出钢口的套砖为添加有抗氧化剂的MT‑18镁碳耐火砖；所述出钢口处的填充料为包括电熔镁砂、SiO2微粉、Cr2O3粉、减水剂PS10和悬浮剂的混合物。针对目前现场使用的出钢口情况和出现的问题，本发明通过对转炉出钢口的材料进行改进，并对出钢口填充物料成分配比方案进行优化，可有效延长转炉出钢口的综合使用寿命，更加方便服务于生产。
