High-strength wear-resistant castable with high cost performance for blast furnace water flushing slag runner as well as preparation method and application thereof
The invention relates to a high-strength wear-resistant castable with high cost performance for blast furnace water flushing slag runner and an application thereof. The high-strength wear-resistant castable is prepared from the following raw materials in percentage by mass: 55 to 70 percent of steel slag aggregate, 10 to 15 percent of pure calcium aluminate cement, 10 to 15 percent of high-alumina cement, 5 to 10 percent of ultrafine powder, 1 to 3 percent of stainless steel fiber, 0.5 to 1 percent of chrome green, 0 to 0.2 percent of sodium tripolyphosphate, 0 to 0.12 percent of FS water reducing agent and 0 to 0.05 percent of citric acid; wherein the sodium tripolyphosphate and the FS water reducing agent are not 0 at the same time. The high-strength wear-resistant castable product is prepared by uniformly mixing according to the ratio at normal temperature, and packaging. The material is stirred by adding water into a stirrer on site, and is subjected to pouring construction, or is made into a precast block, and is transported to the site for direct installation. The product has good construction performance, only needs to be properly maintained, is used for a blast furnace water flushing slag trough lining, has the service life easily exceeding 5 years or more, and does not need to be repaired in the service period.
本发明提供一种较高性价比的高炉水冲渣沟用高强耐磨浇注料及应用，由下列原料按质量百分比组成：钢渣骨料55～70％、纯铝酸钙水泥10～15％、高铝水泥10～15％、超微细粉5～10％、不锈钢纤维1～3％、铬绿0.5～1％、三聚磷酸钠0～0.2％、FS减水剂0～0.12％、柠檬酸0～0.05％，并且三聚磷酸钠与FS减水剂不同时为0。按配比在常温下混匀、包装即得到高强耐磨浇注料产品。将该料在现场用搅拌机加水搅拌、浇筑施工，或做成预制块、运至现场直接安装。本产品施工性能良好，只需适当养护，用于高炉水冲渣沟内衬，寿命轻松超过5年以上，服役期间无需修补。
