摘要: 为了探究高碳铬铁渣作为耐火原料应用到高铝耐磨浇注料的可行性,以高碳铬铁渣、高铝矾土、活性氧化铝微粉、SiO2微粉、纯铝酸钙水泥为主要原料,制备了高铝耐磨浇注料。研究了在不同热处理温度(110、800、1 000、1 200 ℃)下,高碳铬铁渣加入量(质量分数分别为0、20%、40%、60%、80%)对高铝耐磨浇注料结构与性能的影响。结果表明:随着高碳铬铁渣加入量的增加,试样中骨料与基质部分结合紧密,烧结性能较好,试样的体积密度和高温抗折强度逐渐增大、常温抗折强度和常温耐压强度先减小后增大;试样经800 ℃热处理后的磨损量逐渐降低,耐磨性能逐渐提高。

Abstract: In order to explore the application feasibility of high-carbon ferrochromium slag as a refractory raw material in high-alumina wear-resistant castables,high-carbon ferrochromium slag,high-alumina bauxite,activated alumina micropowder,silica micropowder and pure calcium aluminate cement were used as main raw materials to prepare high-alumina wear-resistant castables.The effects of the high-carbon ferrochromium slag addition (0,20%,40%,60%,and 80%,by mass) on the structure and properties of the castables heat treated at different temperatures (110,800,1 000,and 1 200 ℃) were studied.The results show that with the increasing high-carbon ferrochromium slag addition,the bonding between aggregates and matrix is getting tight,and the sintering is improved.The bulk density and hot modulus of rupture of the specimens increase gradually;the cold modulus of rupture and cold compressive strength first decrease and then increase.The wear loss of the samples heat treated at 800 ℃ decreases gradually,so the wear resistance improves gradually.

Key words: high-carbon ferrochromium slag, high-alumina wear-resistant castables, microstructure, wear resistance
