Low-cement refractory castable for pumping construction
The invention relates to a low-cement refractory castable for pumping construction, which comprises a dry material and an additive, the dry material comprises the following components in parts by weight: 55-68 parts of refractory aggregate, 12-27 parts of refractory powder, 3-10 parts of superfine powder and 1-9 parts of binding agent, the additive comprises fibers and a composite additive, the weight of the fibers is 0.01-3% of the weight of the dry material, the weight of the composite additive is 0.1-0.5% of the weight of the dry material, and the weight of the water is 5-12% of the weight of the dry material. The invention provides the low-cement refractory castable with the volume density of 2.2-2.8 g/cm3, the castable makes up the defect that the traditional low-cement refractory castable cannot be pumped, realizes the pumping of the low-cement refractory castable, is convenient for on-site pouring construction, solves the difficult problem of vertical conveying of the refractory castable of a high and large furnace body, reduces the workload of workers, and improves the pouring efficiency; and the stirred material reaches the working surface within a short time, so that the working surface can be prevented from being added with water again, and the performance of the refractory lining is effectively ensured.
本发明涉及一种用于泵送施工的低水泥耐火浇注料，其包括干料和外加剂，其中，干料以重量份计，包括以下组分：55‑68份耐火骨料、12‑27份耐火粉料、3‑10份超微粉、1‑9份结合剂，外加剂包括纤维和复合添加剂，其中纤维的重量为干料重量的0.01‑3%，复合添加剂的重量为干料重量的0.1‑0.5%，该耐火浇注料还包括水，水的重量为干料重量的5‑12%。本发明提供了一种体积密度在2.2—2.8g/cm3的低水泥耐火浇注料，该浇注料弥补了传统低水泥耐火浇注料无法泵送的缺陷，实现了低水泥耐火浇注料的泵送，便于现场的浇注施工，解决了高大炉体耐火浇注料垂直输送的难题，减少了工人的工作量，提高了浇注效率；搅拌好的材料短时间内到达工作面，可避免工作面再次加水，有效保证了耐火衬体的性能。
