Novel scouring-resistant thermal shock-resistant impact brick and preparation method thereof, and current stabilizer
The invention relates to a novel scouring-resistant thermal shock-resistant impact brick. The brick comprises a punch-formed plate and a casting-formed body. The punch-formed plate is prepared from the following raw materials: metal silicon powder, metal aluminum powder, silicon carbide, compact corundum, aluminum-magnesium spinel and an adhesive. The punch-formed plate is integrally punched andformed by using a press machine. The casting-formed body is prepared from a castable through mold casting, vibration molding, maintenance, demolding and baking. The casting-formed body is prepared from the following raw materials: waste corundum particles, fine white corundum powder, aluminum-calcium cement micro-powder, active aluminum powder, micro-silicon powder, a water reducing agent and water. The punch-formed plate is fixed to a preset position in a mold in advance, the periphery of the punch-formed plate is filled with the castable, and the casting-formed body and the punch-formed plate are integrally formed in a pouring mode. According to the impact brick, punch forming and casting forming are combined, material combination is optimized, waste refractory materials are recycled, the scouring resistance of the impact brick is improved, and the continuous scouring resistance time of the impact brick is 3-5 times or above compared with an existing magnesia carbon brick and the like.
本发明涉及一种新型耐冲刷耐热震式冲击砖，其包括冲压成型板和浇注成型体；冲压成型板的原料组成包括：金属硅粉、金属铝粉、碳化硅、致密刚玉、铝镁尖晶石和粘合剂。冲压成型板是采用压力机一体冲压成型；浇注成型体为采用浇注料经模具浇注、振动成型、养护、脱模、烘烤制得。浇注成型体的原料组成包括废旧钢玉颗粒、白钢玉细粉、铝钙水泥微粉、活性铝粉、微硅粉、减水剂和水；冲压成型板预先固定在模具内的预定位置，使浇注料填充在冲压成型板的周围，浇注成型体与冲压成型板一体浇注成型。该冲击砖以冲压成型和浇注成型相结合，并优化材料组合，对废旧耐火材料循环使用，提高冲击砖的耐冲刷性能，耐连续冲刷时间为现有镁碳砖等的3‑5倍以上。
