Preparation method of carbon-free castable added with graphite raw material and used for refining steel ladle working lining
The invention provides a preparation method of a carbon-free castable added with a graphite raw material for a refined steel ladle working lining. The preparation method of the carbon-free castable added with the graphite raw material for the refined steel ladle working lining comprises the following steps: S1, preparing raw materials: (1) preparing the raw materials: aggregate and fine materials; (2) preparing binding agents: rho-Al2O3 (aluminum oxide) and alpha-Al2O3 (aluminum oxide); and S2, molding: (1) putting the aggregate and the fine material in the step (1) into equipment according to a mass ratio of 70: 30, uniformly mixing by the equipment, carrying out material vibration casting molding, and then curing for 24 hours. The preparation method of the carbon-free castable added with the graphite raw material and used for refining the steel ladle working lining has the advantages that the content of carbon in molten steel can be reduced, and meanwhile, the average service life of a steel ladle is prolonged, so that the cost of a steel ladle refractory material per ton of steel is reduced; and the steel ladle building cost and the labor intensity of workers are reduced, and the steel ladle building time is saved.
本发明提供一种精炼钢包工作衬用加入有石墨原料的无碳浇注料制备方法。所述精炼钢包工作衬用加入有石墨原料的无碳浇注料制备方法包括以下步骤：S1、原料：(1).准备原料：骨料和细料；(2).准备结合剂：ρ‑Al2O3(氧化铝)和α‑Al2O3(氧化铝)；S2、成型：(1).将上述S1中(1)的骨料和细料按照比例70:30的质量比投入到设备中，通过设备混合均匀后，进行料振动浇注成型，然后在养护24h。本发明提供的精炼钢包工作衬用加入有石墨原料的无碳浇注料制备方法具有可以减少钢水中碳的含量,同时钢包的平均使用寿命提高了，因此降低了钢包耐火材料的吨钢成本，降低了钢包砌筑成本、工人的劳动强度和节约砌筑钢包时间的优点。
