摘要
以武钢程潮铁矿尾矿为主要原料,添加一定量自制的的着色助剂TM,按传统通体砖生产工艺制备黑色通体砖,探索出了一条利用铁尾矿生产低成本高档建材产品的有效途径。试验结果表明:在铁尾矿与TM的质量比=98.4∶1.6,球磨时间为36 h(球、料、水质量比=2∶1∶1),泥浆均化时间为24 h,造粒加水量为6%,粒料陈腐时间为48 h,压制压力为60 MPa,烧成温度为1 180℃,保温时间为50 m in的条件下,制得的黑色通体砖符合国家标准,其吸水率为0.30%,断裂模数为69 MPa,破坏强度为1 503 N。
With the traditional production technology and taking Chengchao iron tailings of Wusteel as the main raw materials,black body brick is prepared by adding a mount of self-developed coloring aid additives.So,the effective method of producing low-cost and high-grade building materials is explored.The tests result indicated that under the condition of the ratio of iron tailing to TM of 98.4∶1.6,ball grinding time 36 h,slurry equalizing time 24 h,water adding by 6% in pelleting,pelleting hold time of 48 h,molding pressure 60 MPa and heat preservation for 50 min at 1 180 ℃,the performance of black body brick met the national standards with water adsorption rate of 0.30%,rupture modulus of 69 MPa,damage intensity of 1 503 N.
