Molten iron tank bottom impact area precast block and preparation method thereof
The invention relates to a molten iron tank bottom impact area precast block and a preparation method thereof. The prefabricated block is prepared from the following raw materials in parts by weight: 10-15 parts of high-alumina bauxite, 40-50 parts of regenerated iron runner material, 20-25 parts of sintered tabular corundum, 8-12 parts of silicon carbide, 2-5 parts of cement, 5-10 parts of compound alumina micro powder, 3-6 parts of silica fume, 0.1-0.2 part of high-efficiency water reducing agent, 2-4 parts of carbon-containing material, 3-5 parts of zirconium mullite and 0.1-0.3 part of explosion-proof fiber. The method is low in cost, convenient to construct, good in integrality and good in anti-erosion effect, the lining bricks are prevented from being ejected out by tank bottom iron seepage, and the conditions of brick breakage and brick falling in the use process of the molten iron tank bottom are prevented.
本发明涉及一种铁水罐罐底冲击区预制块及其制备方法，所述预制块是由下列重量份数的原料制备而成：高铝矾土10～15份、铁沟料再生料40～50份、烧结板状刚玉20～25份、碳化硅8～12份、水泥2～5份、复配氧化铝微粉5～10份、硅灰3～6份、高效减水剂0.1～0.2份、含碳材料2～4份、锆莫来石3～5份、防爆纤维0.1～0.3份。本发明成本低、施工方便、整体性好，抗侵蚀效果好，防止罐底渗铁将衬砖顶出，防止铁水罐底使用过程中出现断砖、掉砖的情况。
