Method for synthesizing periclase-forsterite refractory material at low temperature
The invention discloses a method for synthesizing a periclase-forsterite refractory material at low temperature, which comprises the following steps: preparing the following raw materials in parts by weight: 8-20 parts of high-silicon magnesite, 15-30 parts of magnesium oxide raw material, 8-15 parts of talc ore and 3-8 parts of additional silica sol; the method comprises the following steps: heating high-silicon magnesite to 600-900 DEG C, preserving heat for 4-6 hours to prepare high-silicon magnesite clinker, and crushing and sieving the clinker to obtain high-silicon magnesite clinker fine powder; the high-silicon magnesite is used as a main raw material, low-grade mineral resources are fully utilized, the production cost is reduced, the production benefit is improved, in addition, in the processing process, thermal stress generated by thermal expansion and shrinkage of the refractory material is absorbed and released, slag permeation and structural stripping of the refractory material are avoided, and the quality of the refractory material is improved. And the service life of the refractory material is prolonged. The silica sol, which is one of the raw materials, has relatively small granularity and superplasticity, is beneficial to reducing the preparation temperature of the periclase-forsterite refractory material, and has the effects of saving energy and reducing consumption.
本发明公开了一种低温合成方镁石‑镁橄榄石耐火材料的方法，以重量份计，需准备以下的重量份数原料，高硅菱镁矿8‑20份、氧化镁原料15‑30份和滑石矿8‑15份，硅溶胶外加3‑8份；将高硅菱镁矿升温至600～900℃，保温4～6h，制备高硅菱镁矿熟料，将熟料经破碎、过筛，可得到高硅菱镁矿熟料细粉；本发明通过以高硅菱镁矿为主要原料，充分利用低品位矿产资源，降低生产成本，提高生产效益，另外该方式在加工过程中不仅吸收和释放了耐火材料热膨胀和收缩产生的热应力，避免熔渣渗透和耐火材料的结构剥落，延长了耐火材料的使用寿命。原料之一的硅溶胶具有较小的粒度和超塑性，利于降低方镁石‑镁橄榄石耐火材料的制备温度，具有节能降耗的作用。
