A sedimentation method is proposed to fabricate functionally graded materials (FGMs) with the continuous and smooth variations of composition. The relations between the compositional distribution of deposited body and the powder characteristics of raw materials as well as settling parameters are derived. Subsequently, the mathematical model of forming FGM based on the co-sedimentation has been established. At last, numerical simulations are conducted to explore the effects of the particle sizes of raw materials and suspension height on the compositional distribution of final products.

通过借助工序能耗概念,对板坯连铸工序的能耗值进行研究计算,得到典型板坯连铸工序能耗基准值为7.08 kgce/t铸坯.分析结果可知,板坯连铸过程水、煤气和压缩空气为主要的耗能指标项.为提高铸机工序能效指标,应该从提升铸坯的热装比,严格制定二冷配水制度和烘烤制度上出发,提高能源利用率,提升工序的现代化程度.
