【摘要】：以高铝粉煤灰为主要原料,高碳铬铁合金渣为辅助原料,采用高温发泡法制备出一种新型粉煤灰隔热耐火砖,并系统研究了助熔剂掺量、辅助原料掺量以及发泡剂种类等对隔热耐火砖性能的影响。结果表明:借助于高温发泡法,所制备出的隔热耐火砖,其体积密度≤500 kg·m~(-3)、常温抗压强度≥6 MPa、1250℃下加热永久线变化≤2%,是一种轻质高强且低导热的隔热耐火材料。
[Abstract]:Using high alumina fly ash as main raw material and high carbon ferrochrome slag as auxiliary material, a new type of fly ash heat insulating refractory brick was prepared by high temperature foaming method. The effects of the amount of auxiliary raw materials and the kinds of foaming agents on the properties of insulating refractory brick are studied. The results show that the insulating refractory brick is prepared by means of high temperature foaming method. The volume density 鈮，
