摘要/Abstract

摘要： 探讨了一种用于测试铝土矿尾矿碳热法制取铝硅合金中生团块真密度的方法，并用容重法验证了其可行性. 在此基础上，以抗压强度和气孔率为指标，通过单因素实验和正交实验，考察了制团压力、干粉粘结剂含量、配水量、尾矿粒度对生团块性能的影响. 结果表明，获取优质生团块的最佳工艺条件为：制团压力22.5 MPa，干粉粘结剂含量9%(w)，配水量13%(w)，尾矿粒度0.42~0.178 mm. 此时生团块的抗压强度为27.8 MPa，气孔率为18.7%.

Abstract: In order to measure true density of green pellets which were used to produce Al-Si alloy with bauxite tail by carbothermal method, a novel method was proposed and its feasibility testified by the volume-weight method. Based on the method, the influences of pressing pressure, dry agglomerant content, moisture content and particle size on the properties of green pellets were investigated by single-factor and orthogonal experiments using the compressing strength and pore ratio of green pellets as indexes. The optimum conditions for the properties of green pellets are obtained as fellows: pressing pressure 22.5 MPa, dry agglomerant content 9%(w), moisture content 13%(w) and particle size 0.42~0.178 mm. Under the optimum conditions, the compressing strength and pore ratio of green pellets are 27.8 MPa and 18.7%, respectively.

Key words: bauxite tail, green pellets, compressing strength, pore ratio, single-factor experiment, orthogonal experiment
