Anti-scouring steel ladle bottom castable and production method thereof
The invention relates to an anti-scouring steel ladle bottom castable and a production method thereof, and belongs to the technical field of refractory materials. The anti-scouring steel ladle bottom castable comprises the following components: a granular material, a powder material, fused magnesite, a binding agent and an additive. The granular material is formed by mixing alumina, corundum and corundum spinel reclaimed materials; the powder material is formed by mixing corundum fine powder or micro powder, spinel fine powder or micro powder and alpha-Al2O3 micro powder; the binding agent is a mixture of calcium aluminate cement, magnesium gel and silica fume in any ratio; the additive is a mixture of a polycarboxylic acid dispersing agent, organic acid and fiber in any ratio. The steel ladle bottom working lining constructed by using the steel ladle bottom castable or the precast block has the characteristic of balanced performance, namely, the steel ladle bottom working lining has excellent anti-explosion, anti-scouring, anti-slag-corrosion, anti-stripping and thermal shock performance, the effect of prolonging the service life of the ladle lining and improving the turnover rate of the steel ladle is obvious, and the cost performance is high.
本发明涉及一种抗冲刷钢包包底浇注料及其生产方法，属于耐火材料技术领域。且所述抗冲刷钢包包底浇注料包括以下成分：颗粒料、粉料、电熔镁砂、结合剂、外加剂。所述颗粒料为矾土、刚玉、刚玉尖晶石质再生料混合组成；所述粉料为刚玉细粉或微粉、尖晶石细粉或微粉、α‑Al2O3微粉混合组成；所述结合剂为铝酸钙水泥、镁凝胶和硅灰的任意比混合物；所述外加剂为聚羧酸类分散剂、有机酸、纤维的任意比混合物。用本发明提供的钢包包底浇注料或预制块施工的钢包底工作衬具有各项性能均衡的特点，即具有优良的防爆裂、抗冲刷、抗渣侵蚀、抗剥落和热震性能，对提高包衬使用寿命和钢包周转率效果显著，且性价比高。
