Sol-combined high-thermal-conductivity composite steel fiber toughened refractory castable and preparation method thereof
The invention relates to the field of refractory materials, in particular to a sol-combined high-thermal-conductivity composite steel fiber toughened refractory castable and a preparation method thereof. The silicon carbide ceramic is prepared from the following raw materials in parts by mass: 40-60 parts of silicon carbide, 1-3 parts of graphite particles, 15-30 parts of steel fibers, 5-25 parts of tabular corundum, 3-5 parts of titanium nitride, 2-6 parts of fused quartz powder, 1-3 parts of silica powder, 0.17-0.30 part of a composite dispersing agent, 7.5-8.5 parts of a binding agent and 0.1-0.5 part of a hardening accelerator. The silica sol combined high-thermal-conductivity composite steel fiber toughened refractory castable for the blast furnace cooling wall, provided by the invention, has the advantages of easiness in slag adhesion, high strength, high wear resistance and capability of forming a tight combination body with the cooling wall; the method has remarkable effects of improving the slag adhering performance of the cooling wall area, prolonging the service life of the cooling wall and maintaining the blast furnace operation profile.
本发明涉及耐火材料领域，具体涉及一种溶胶结合高导热复合钢纤维增韧耐火浇注料及其制备方法。其由包括以下质量份数的原料配制而成：碳化硅40份~60份、石墨粒1份~3份、钢纤维15份~30份、板状刚玉5份~25份、氮化钛3份~5份、熔融石英粉2份~6份、硅微粉1份~3份、复合分散剂0.17份~0.30份、结合剂7.5份~8.5份、促硬剂0.1份~0.5份。本发明提供的高炉冷却壁用硅溶胶结合高导热复合钢纤维增韧耐火浇注料，该浇注料具有易挂渣、高强度、高耐磨及能够与冷却壁形成紧密结合体的优点，对于提升冷却壁区域挂渣性能、延长冷却壁使用寿命、维护高炉操作炉型具有显著效果。
