Method for preparing refractory castable from waste refractory material
The invention relates to the technical field of refractory castable, in particular to a method for preparing refractory castable from waste refractory materials, which sequentially comprises the following steps: sorting: sorting the recycled waste refractory materials according to the aluminum content and condition, and removing impurities; crushing: the sorted waste refractory material is crushed, and qualified materials of 3-12 mm are screened; the aggregate comprises the following components in parts by weight: 12-40 parts of a waste refractory material, 10-18 parts of bauxite and 19-40 parts of corundum; the powder material is prepared from the following components in parts by weight: 13 to 23 parts of silicon carbide, 5 to 10 parts of asphalt, 2 to 6 parts of binding agent, 0.03 to 0.06 part of explosion-proof fiber, 0.15 to 0.28 part of boron carbide powder, 1 to 2 parts of metal aluminum powder and 0.15 to 0.24 part of water reducing agent; the adjusting material comprises 2-40 parts of high-aluminum bauxite or high-aluminum corundum; mixing: firstly, putting the powder into a stirrer, stirring for 6-8 minutes, then adding the aggregate and the adjusting material into the stirrer, and stirring for 3-5 minutes; and packaging: packaging the uniformly stirred and mixed materials.
本发明涉及耐火浇注料技术领域，利用废旧耐火材料制备耐火浇注料的方法，依次包括如下步骤：分选：将回收后的废旧耐火材料，按照含铝量和品相进行分选，去除杂质；破碎：将分选后的废旧耐火材料，进行破碎，并按照3～12mm的合格物料进行筛分；配料：按照重量份数，骨料包括：废旧耐火材料12～40份、铝矾土10～18份、刚玉19～40份；粉料包括：化硅13～23份、沥青5～10份、结合剂2～6份、防爆纤维0.03～0.06份、碳化硼粉0.15～0.28份、金属铝粉1～2份、减水剂0.15～0.24份；调整料包括高铝铝矾土或高铝刚玉2～40份；混料：先将粉料置于搅拌机内，搅拌6～8分钟，再将骨料和调整料加入搅拌机内搅拌3～5分钟；包装：将搅拌混合均匀后的物料进行包装。
