Silicon carbide plastic refractory for grate furnace
The invention discloses a silicon carbide plastic refractory for a grate furnace. The silicon carbide plastic refractory is prepared from the following raw materials in parts by mass: 40-45 parts of silicon carbide aggregate, 25-30 parts of silicon carbide powder, 10-15 parts of corundum aggregate, 5-10 parts of alumina micro powder, 5-8 parts of a binding agent, 1-2 parts of metal silicon powder and 0.1-0.3 part of a dispersing agent, and the binding agent is obtained by mixing an MgTiAl hydrotalcite intercalation material with silica sol. The silicon carbide plastic refractory for the grate furnace is high in strength, excellent in corrosion resistance, wear resistance and high-temperature-resistant stability and long in service life.
本发明公开了一种炉排炉用碳化硅可塑料，包括下述质量份的原料：碳化硅骨料40‑45份、碳化硅粉料25‑30份、刚玉骨料10‑15份、氧化铝微粉5‑10份、结合剂5‑8份、金属硅粉1‑2份、分散剂0.1‑0.3份；所述结合剂是将MgTiAl水滑石类插层材料与硅溶胶混合得到。本发明的炉排炉用碳化硅可塑料具备高强度、优良的耐腐蚀性、耐磨性和耐高温稳定性，使用寿命长。
