Sol combined hearth self-flowing castable
The invention provides a sol combined hearth self-flowing castable. The sol combined hearth self-flowing castable comprises the following components in percentage by mass: 70%-80% of white corundum, 8%-14% of silicon carbide, 4%-9% of alpha-aluminum oxide, 2%-8% of zirconium silica fume, 0.05%-0.3% of chromium carbide, 0.05%-0.3% of metal aluminum powder, 0.05%-0.3% of metal titanium powder, 0.01%-0.1% of organic fibers and 0.3%-1.2% of a coagulant. The sum of the mass percentages of the components is 100%. The silica sol accounts for 6-15% of the total mass of the components. According to the sol-combined hearth self-flowing castable, chromium carbide, metal aluminum powder and metal titanium powder are added, titanium-aluminum-carbon ternary layered ceramic with high melting point, high hardness, high thermal stability, high oxidation resistance and high compactness is generated in situ at high temperature in the using process, through holes are filled, and the castable has remarkably higher high-temperature performance.
本发明提供一种溶胶结合炉缸自流浇注料，包括以下质量百分比的组分：白刚玉70%‑80%、碳化硅8%‑14%、α‑氧化铝4%‑9%、锆硅灰2%‑8%、碳化铬0.05%‑0.3%、金属铝粉0.05%‑0.3%、金属钛粉0.05%‑0.3%、有机纤维0.01%‑0.1%、促凝剂0.3%‑1.2%；上述组分的质量百分比的总和为100%；还包括占上述组分总质量6%‑15%的硅溶胶。该溶胶结合炉缸自流浇注料通过加入碳化铬、金属铝粉、金属钛粉，三者在使用过程中高温下原位生成具有高熔点、高硬度、高热稳定性、高抗氧化性且致密性高的钛铝碳三元层状陶瓷，填充通孔，使浇注料具有显著更高的高温性能。
