The invention relates to a ramming material for a steel ladle and a preparation method thereof. The ramming material comprises the following components in percentage by weight: 45-55% of regenerated ramming material; 20-25% of silicon carbide powder; 10%-15% of bauxite; 3-5% of silicon nitride powder; 3-5% of bentonite; 3-5% of modified resin; and 2-5% of aluminum silicate fiber.s The preparation method comprises the following steps: (1) sorting regenerated ramming materials to remove impurities, putting the ramming materials into a crusher, and performing crushing and sieving; (2) mixing the regenerated ramming material with silicon carbide powder, bauxite, silicon nitride powder and bentonite in a mixer; and (3) uniformly mixing the rubber powder, the starch and the paper pulp powder. The ramming material is obtained by sorting the reclaimed material, removing impurities, performing crushing and mixing and compounding with other raw materials and the plasticizer, so that the recycling of high-value raw materials is achieved, the production cost is effectively reduced, the problems of poor plasticity and viscosity are solved by the plasticizer, the overall performance of the ramming material is improved, and the service life of the ramming material is prolonged.
本发明涉及一种钢包用捣打料及其制备方法，捣打料按重量比例的组份如下：再生捣打料45～55％；碳化硅粉20～25％；铝矾土10～15％；氮化硅粉3～5％；膨润土3～5％；改性树脂3～5％；硅酸铝纤维2～5％。制备方法包括：(1)将再生捣打料经拣选去除杂质，投入破碎机粉碎后过筛；(2)将再生捣打料与碳化硅粉、铝矾土、氮化硅粉、膨润土，放入混料机中混合；(3)将胶粉、淀粉和纸浆粉均匀混合。本发明采用再生料经过拣选、去除杂质后粉碎，与其它原料和增塑剂一起混合复配得到捣打料，实现高价值原材料的循环再利用，有效生产降低成本，通过增塑剂解决塑性和粘性差的问题，从而提高捣打料的整体性能和使用寿命。
