Blast furnace taphole mud sleeve manufacturing method
The invention discloses a blast furnace iron notch mud sleeve manufacturing method. The method comprises the steps that S1, an old mud sleeve at a blast furnace iron notch is removed; s2, a sprue gate is manufactured; s3, the mixture is poured from a sprue gate; wherein the mixed material is formed by mixing a castable and silica sol, and the castable is prepared from the following components in percentage by mass: 70 to 74 percent of Al2O3, 15 to 17 percent of SiC, 5 to 8 percent of SiO2, 0.5 to 0.6 percent of Fe2O3, 1.5 to 2.5 percent of TiO2, 0.4 to 0.7 percent of CaO and 0.5 to 1.5 percent of C. According to the manufacturing method of the blast furnace taphole mud sleeve, the mixture of special materials is adopted for pouring, the service life of the taphole mud sleeve can be greatly prolonged, the replacement frequency of the taphole mud sleeve is reduced, and then the workload of operators can be reduced.
本发明公开了一种高炉铁口泥套制作方法，包括步骤：S1、去除高炉铁口处的旧泥套；S2、制作浇注口；S3、将混合料从浇注口进行浇注；其中，所述混合料是由浇注料和硅溶胶混合而成，浇注料包括以下质量百分比成分：Al2O3：70～74％，SiC：15～17％，SiO2：5～8％，Fe2O3：0.5～0.6％，TiO2：1.5～2.5％，CaO：0.4～0.7％，C：0.5～1.5％。本发明的高炉铁口泥套制作方法，采用特殊材料的混合料进行浇注，能够大幅提高铁口泥套的寿命，减小铁口泥套更换频次，进而可以减少作业人员工作量。
