Molochite anti-skinning castable and preparation method of prefabricated part
The invention relates to the field of refractory materials, in particular to a molochite anti-skinning castable and a preparation method of a prefabricated member. The anti-skinning castable comprises the following components in parts by weight: 50-60 parts of corundum powder, 30-40 parts of molochite sand, 10-20 parts of alumina powder, 5-10 parts of metal aluminum powder, 10-15 parts of silica sol and 5-10 parts of boron nitride, wherein the metal aluminum powder is coated with the silica sol. The molochite anti-skinning castable disclosed by the invention has good thermal shock resistance, high-temperature stability and chemical corrosion resistance, so that the molochite anti-skinning castable can adapt to a complex use environment, and meanwhile, the castable can enable the surface of the prefabricated part to be smoother and more compact in the sintering process, so that the anti-skinning effect of the prefabricated part can be improved.
本发明涉及耐火材料领域，尤其涉及一种莫来卡特抗结皮浇注料及预制件的制备方法，结皮浇注料，按照重量分数计，包括刚玉粉50~60份、莫来卡特砂30~40份、氧化铝粉10~20份、金属铝粉5~10份、硅溶胶10~15份以及氮化硼5~10份，其中：所述金属铝粉包覆在硅溶胶内部。本发明中的莫来卡特抗结皮浇注料，具有良好的热震稳定性、高温稳定性以及抗化学腐蚀，从而能够适应复杂的使用环境，同时浇注料在烧结过程中能够使得预制件的表面更加光滑致密，从而能够提升其抗结皮效果。
