Construction process for repairing and maintaining long-life steel ladle
The invention discloses a construction process for repairing and maintaining a long-life steel ladle. The construction process comprises the following steps: (1) respectively preparing repairing materials, namely a corundum spinel repairing material for a steel ladle wall and a magnesia carbon repairing material for a steel ladle slag line; (2) a new steel ladle lining is constructed on the inner wall of the steel ladle through the corundum spinel repairing material for the steel ladle wall in a 3D printing or jetting mode, and the steel ladle slag line part is constructed through the magnesia carbon repairing material for the steel ladle slag line; and (3) after all construction in the step (2) is completed, the steel ladle is baked. The problems that an existing steel ladle is high in repairing frequency and poor in repairing effect can be solved; the process is used for regularly repairing and maintaining the steel ladle at normal temperature, so that the lining of the steel ladle recovers to the thickness of a new ladle, the steel ladle can be safely and reliably used for a long time, the labor intensity of constructors is greatly reduced, and the consumption of refractory mineral raw materials per ton of steel is reduced.
本发明公开一种长寿命钢包修复维护施工工艺，包括如下步骤：步骤(1)、分别配制修复料：钢包包壁用刚玉尖晶石修复料和钢包渣线用镁碳质修复料；步骤(2)、采用3D打印或喷注的方式在钢包内壁上利用钢包包壁用刚玉尖晶石修复料施工形成新的钢包内衬，利用钢包渣线用镁碳质修复料施工钢包渣线部位；步骤(3)、待步骤(2)的施工全部完成后，对钢包进行烘烤。本发明能够解决现有钢包修复次数多、修复效果差的问题；使用该工艺定期对钢包进行常温修复维护，使钢包内衬恢复到新包厚度，可保证钢包安全可靠的长期使用，大大降低施工人员劳动强度、降低耐火矿物原料的吨钢消耗。
