Transition brick layer for ladle wall of working lining of steel ladle
The invention relates to a transition brick layer for a ladle wall of a working lining of a steel ladle, wherein the ladle wall sequentially comprises a slag line part (1) and a working layer (2) from top to bottom, the slag line part is made of a magnesia carbon brick material, and the working layer is made of a corundum spinel material; the transition brick layer (3) is built between the slag line part (1) and the working layer (2), the transition brick layer (3) is made of an Al2O3-MgO-CaO material, and the transition brick layer (3) comprises chemical components in percentage by weight as follows: 88.0%-93.0% of Al2O3, 5.0%-9.0% of MgO, 1.5%-3.0% of CaO and the balance of trace impurities. According to the invention, the brick joints between the slag line part and the working layer can be effectively controlled to be enlarged, molten steel permeation is reduced, and the service life of the steel ladle is prolonged.
本发明涉及一种用于钢包工作衬包壁的过渡砖层，所述包壁从上至下依次包括渣线部（1）和工作层（2），所述渣线部为镁碳砖材料，所述工作层为刚玉尖晶石材料；所述过渡砖层（3）砌筑在渣线部（1）和工作层（2）之间，过渡砖层（3）为Al2O3‑MgO‑CaO质材料，其化学组分按重量百分比为：Al2O3：88.0~93.0%、MgO：5.0~9.0%、CaO：1.5~3.0%，其余为微量杂质。本发明能有效控制渣线部和工作层之间的砖缝扩大，减少钢水渗入，提高钢包使用寿命。
