Special zirconium, corundum and mullite composite brick for roller kiln
The invention discloses a special zirconium, corundum and mullite composite brick for a roller kiln. The special zirconium, corundum and mullite composite brick comprises a first composite layer, a second composite layer and a third composite layer, the first composite layer is prepared from the following raw materials in parts by weight: 40-50 parts of zircon powder, 10-15 parts of dolomite, 3.5-5.5 parts of metal aluminum powder, 3.5-5.5 parts of metal silicon micro powder, 30-55 parts of kaolin, 3-6 parts of floating beads, 1-5 parts of cellulose dry powder and 2-6 parts of a binding agent; the second composite layer is prepared from the following raw materials in parts by weight: 36-54 parts of mullite powder, 5-8 parts of talcum powder, 30-50 parts of kaolin, 8-12 parts of a binding agent and 6-10 parts of cellulose dry powder; the invention effectively solves the problems that the perforated brick for the roller kiln is always produced from materials such as clay, high aluminum and the like before, and has the following defects in the use process: the perforated brick cannot meet the requirements of the existing roller kiln due to low working temperature, is low in refractoriness under load and is easy to crack, and has poor thermal stability and poor high-temperature thermal shock resistance.
本发明公开了辊道窑专用锆、刚玉、莫来石复合砖，包括第一复合层、第二复合层和第三复合层；所述第一复合层是由原料锆石粉40‑50份、白云石10‑15份、金属铝粉3.5‑5.5份、金属硅微粉3.5‑5.5份，高岭土30‑55份、漂珠3‑6份、纤维素干粉1‑5份和结合剂2‑6份；所述第二复合层是由原料莫来石粉36‑54份、滑石粉5‑8份、高岭土30‑50份、结合剂8‑12份和纤维素干粉6‑10份；本发明有效的解决了琨道窑用孔砖以前一直是沿用黏土、高铝等材料生产，在使用过程中存在以下缺点：工作温度偏低不能满足现有辗道窑的要求，荷重软化温度低，易破裂，二是热稳定性差﹑耐高温热冲击能力差的问题。
