Corundum and andalusite combined silicon carbide cast steel brick
The invention discloses a corundum and andalusite combined silicon carbide cast steel brick, which is prepared from the following raw materials in percentage by weight: 5 to 10 percent of 200-mesh ball clay, 1 to 8 percent of 325-mesh silicon carbide, 2 to 15 percent of 54-mesh alpha-Al2O3, 18 to 28 percent of 200-mesh tabular corundum, 15 to 25 percent of 1 to 0mm andalusite, 15 to 30 percent of 3 to 1mm low-aluminum mullite and 5 to 15 percent of 1 to 0mm tabular corundum. According to the corundum and andalusite combined silicon carbide cast steel brick, the porosity in the corundum and andalusite combined silicon carbide cast steel brick is greatly reduced to 18%, and the thermal stability is greatly improved, so that the phenomenon of fault damage is avoided at a high temperature, the pressure resistance is greatly improved to 100 MPA, the compression strength of the corundum and andalusite combined silicon carbide cast steel brick can be improved, and the service life of the corundum and andalusite combined silicon carbide cast steel brick is prolonged. Meanwhile, steel adhesion is basically avoided in the machining process, the erosion resistance is improved, waste bricks can be recycled, and therefore use of raw materials can be reduced in the production process.
本发明公开了刚玉红柱石结合碳化硅浇钢砖，是由球黏土200目5％‑10％，碳化硅325目1％‑8％，α‑AL2O3 54目2％‑15％，板状刚玉‑200目18％‑28％，红柱石1‑0mm 15％‑25％，低铝莫来石3‑1mm15％‑30％，板状刚玉1‑0mm 5％‑15％原材料组成的，该刚玉红柱石结合碳化硅浇钢砖内部的气孔率大幅下降至18％，并且热稳定性大幅提高，这样在高温中不会出现断层破坏的现象，而且耐压强大大幅提高至100MPA，这样可以提高该刚玉红柱石结合碳化硅浇钢砖的耐压强度，同时在加工时基本不沾钢，提高了抗侵蚀能力，废砖可以回收再利用，从而可以在生产过程中降低原材料的使用。
