Low-heat-dissipation long-service-life steel ladle lining body and preparation method thereof
The invention relates to a low-heat-dissipation long-service-life steel ladle lining body and a preparation method thereof. According to the technical scheme, the steel ladle lining body is sequentially composed of a working lining, a permanent lining and a heat insulation lining from inside to outside. The preparation method of a refractory castable of a phase-change heat storage material adoptedby the refractory material for the wrapping edge of the working lining and the refractory material for the permanent lining comprises the following steps: taking 5-20 parts by mass of alumina particles and 35-55 parts by mass of alumina-alloy composite particles as aggregates, and taking 25-35 parts by mass of alumina fine powder, 4-6 parts by mass of alpha-Al2O3 micro powder, 0.1-1 part by massof silica powder and 4-6 parts by mass of calcium aluminate cement as matrixes; uniformly mixing the matrixes with 0.1-0.2 part by mass of polycarboxylic acid, performing mixing with the aggregate, adding 3-5 parts by mass of water, and performing uniform stirring to obtain the refractory castable containing the phase change heat storage material. The steel ladle lining body prepared by the methodhas the characteristics of low heat dissipation, small temperature fluctuation of the working lining and long service life of the steel ladle lining body.
本发明涉及一种低热耗散长寿命钢包衬体及其制备方法。其技术方案是：所述钢包衬体由里向外依次由工作衬、永久衬和隔热衬组成。工作衬的包沿用耐火材料和永久衬用耐火材料所采用的相变蓄热材料的耐火浇注料的制备方法是：以5～20质量份的矾土颗粒、35～55质量份的矾土‑合金复合颗粒为骨料，以25～35质量份的矾土细粉、4～6质量份的α‑AlO微粉、0.1～1质量份的硅微粉和4～6质量份的铝酸钙水泥为基质；先将基质与0.1～0.2质量份的聚羧酸混合均匀，再与骨料混合，然后加入3～5质量份的水，搅拌均匀，得到含相变蓄热材料的耐火浇注料。本发明制备的钢包衬体具有热耗散低、工作衬温度波动小和钢包衬体寿命长的特点。
