Method for prolonging service life of steel ladle
The invention relates to the technical field of metallurgy, in particular to a method for prolonging the service life of a steel ladle, which comprises the following steps: manufacturing a steel ladle tire film, preparing a castable, adding the prepared castable into a stirrer for dry mixing, then adding water, and continuously stirring until the mixture is uniformly stirred to form a casting material; according to the method, the pouring material is placed into the steel ladle tire film, overall ramming is conducted, the durable steel ladle structure is manufactured, the steps are simple, operation is easy and convenient, the durable steel ladle structure is manufactured through cooperation with the pouring material and overall ramming, the conditions of dead corners and cavities can be effectively avoided, and the service life of the steel ladle structure is effectively prolonged; the formula of the castable is optimized and adjusted: Al2O3 + MgO is greater than or equal to 83%, so that the compressive strength (1500 DEG C * 3h) is greater than or equal to 80MPa, the linear change (1500 DEG C * 3h) is +/-0.5%, the refractoriness is greater than or equal to 1750 DEG C, and the service life can be effectively prolonged.
本发明涉及冶金技术领域，具体涉及一种提高钢包使用寿命的方法，包括制作钢包胎膜，配置浇注料，并将配置好的浇注料加入搅拌机干混后，再加入水，继续搅拌，直至搅拌均匀，形成浇注材料；将浇注材料放入钢包胎膜，进行整体捣打，制成耐用钢包结构，其步骤简单，操作简便，通过配合浇注料，并整体捣打制成耐用钢包结构，可以有效避免出现死角和空洞情况，有效提高了钢包结构的使用寿命，此外，本申请通过对浇注料配方进行优化调整：Al2O3+MgO≥83％，使得耐压强度(1500℃×3h)≥80MPa，线变化(1500℃×3h)±0.5％，耐火度≥1750℃，可有效的提升使用寿命。
