Refractory material prepared from low-aluminum high-magnesium-silicon secondary aluminum ash and process
The invention provides a refractory material prepared from low-aluminum high-magnesium-silicon secondary aluminum ash and a process, and relates to the technical field of refractory materials, magnesite pretreatment: firstly grinding magnesite, and then calcining the magnesite at the temperature of 800-900 DEG C; secondary aluminum ash pretreatment: calcining the secondary aluminum ash at the temperature of 900-1000 DEG C; grinding and mixing: respectively grinding the calcined magnesite and secondary aluminum ash to obtain corresponding powder, mixing the ground magnesite powder and secondary aluminum ash powder, and adding an additive in the mixing process to obtain a mixture; calcining: calcining the mixture in an oxygen-enriched environment at the temperature of 1550-1750 DEG C, and cooling after calcining to obtain the refractory material. The secondary aluminum ash adopted by the invention is high-magnesium secondary aluminum ash special in Qinghai and has the characteristics of high magnesium content and high silicon content, and the secondary aluminum ash is converted into a raw material capable of preparing the refractory material, so that resources can be fully utilized, and the purposes of reducing cost and improving efficiency can be achieved for enterprises.
本发明提供一种利用低铝高镁硅二次铝灰制备耐火材料及工艺，涉及耐火材料的技术领域，菱镁砂前处理：先对菱镁砂进行研磨，然后再将菱镁砂在温度为800‑900℃下进行煅烧；二次铝灰前处理：将二次铝灰在温度为900‑1000℃下进行煅烧；研磨混合：将煅烧后的菱镁砂和二次铝灰分别进行研磨得到对应的粉末物，将其研磨后菱镁砂粉末物和二次铝灰粉末物进行混合，在混合过程中加入外加剂得到混合物；煅烧：将混合物在富氧环境中，温度为1550‑1750℃条件下进行煅烧，煅烧结束冷却得到耐火材料。本发明采用的二次铝灰是选用青海特有的高镁二次铝灰，具有镁、硅含量高的特点，将二次铝灰转化为能够制备耐火材料的原料，能够达到对资源的充分利用，还能为企业达到降本增效的目的。
