Cast-molded sliding plate brick for slag stopping of converter tapping hole and production method
The invention provides a cast-molded sliding plate brick for slag stopping of a converter tapping hole. The cast-molded sliding plate brick is prepared from the following raw materials: 65-78% of tabular corundum, 8-12% of magnesium-rich spinel, 3-7% of silicon carbide, 6-10% of alpha-aluminum oxide micro powder, 1-2% of pure calcium aluminate cement, 3-6% of rho-aluminum oxide micro powder and 0.05-0.2% of a water reducing agent. During production, the raw materials and the water reducing agent are weighed, stirring is conducted by a stirrer to obtain pug, pouring and vibration molding are carried out, after 24h of curing, demoulding is conducted, drying treatment is performed at 300+/-10DEG C, and then grinding and coating are conducted to obtain the product. The sliding plate brick is excellent in integrity, good in erosion resistance, stripping resistance and thermal shock resistance, high in strength and good in use performance.
本发明提供一种浇注成型的转炉出钢口挡渣用滑板砖，原料组成为：65～78％的板状刚玉、8～12％的富镁尖晶石、3～7％的碳化硅、6～10％的α‑氧化铝微粉、1～2％的纯铝酸钙水泥、3～6％的ρ‑氧化铝微粉，外加0.05～0.2％的减水剂。生产时称取各原料及减水剂，经搅拌机搅拌得泥料，浇注振动成型，养护24h后脱模，于300±10℃下干燥处理后、经磨制、涂布即得本发明产品。该滑板砖整体性优越，抗侵蚀性、抗剥落性和热震稳定性好，强度高，使用性能较好。
