多芯复合浇铸钢锭的硫代硫酸钠模拟实验研究
Simulation Experiment of Multi-core Composite Casting Ingot Using Na2SO3 5H20
摘要
Abstract
A multi-core composite casting process was proposed and simulated using Na2SO3 5H2O as melt to solve the problem of segregation,porosity and shrinkage in the traditional ingot.The solidification percentage of sodium thiosulfate melt was determined and the effect of core number on solidification was discussed.The results show that the preset cores in the mould can improve the nucleation on the surface of cores,increase the dendrite rain in melt,raise the proportion of fine equiaxed grains and decrease greatly the solidification time of the melt.With an increase of core number,the dendrite rain rises significantly,solidification rate is faster and the solidification structure is finer and more compact.关键词
