Self-flowing castable containing recycled corundum castable and preparation method of self-flowing castable
The invention discloses a self-flowing castable containing a recycled corundum castable. The self-flowing castable comprises the following raw materials in parts by weight: 25-30 parts of recycled corundum castable with the particle size of 3-5mm, 15-20 parts of recycled corundum castable with the particle size of 1-3mm, 10-12 parts of fused corundum with the particle size of 0.5-1mm, 3-5 parts of fused corundum with the particle size of 0.2-0.5 mm, 8-10 parts of fused corundum with the particle size of 0-0.2 mm, 15-20 parts of multimodal micro powder, 3-5 parts of cement, 0.1-0.2 part of a high-efficiency water reducing agent and 3-5 parts of water. The preparation method comprises the following steps: (1) weighing the raw materials; (2) uniformly mixing the raw materials except water; and (3) adding water, and uniformly mixing to obtain the product. According to the invention, recycled waste castable particles are utilized, and through strict particle size ratio, the high-efficiency water reducing agent and proper micro powder are added for configuration, so that the castable can flow automatically and is compact without vibration.
本发明公开了一种含有回收刚玉浇注料的自流浇注料，包括以下重量份的原料：粒径为3‑5mm的回收刚玉浇注料25‑30份、粒径为1‑3mm的回收刚玉浇注料15‑20份、粒径为0.5‑1mm的电熔刚玉10‑12份、粒径为0.2‑0.5mm的电熔刚玉3‑5份、粒径为0‑0.2mm的电熔刚玉8‑10份、多峰微粉15‑20份、水泥3‑5份、高效减水剂0.1‑0.2份和水3‑5份；制备方法：(1)称取各原料；(2)将除水以外的原料混合均匀；(3)加水，混合均匀，即得。本发明利用回收废旧浇注料颗粒，通过严格的粒度配比，加入高效减水剂和合适的微粉配置，达到浇注料自流，不需要振动而致密。
