炼钢转炉喷溅行为的数值模拟
Numerical modeling on splashing behavior of steelmaking converter
摘要
Abstract
A compressible,non-isothermal and three-dimensional VOF model was developed to study the transport phenomena occurred during the interaction of the jets with the molten bath in a steelmaking BOF. Efforts were especially made to study the change of gas -slag -metal interface during blowing process,to reveal the formation mechanism and to quantify the rate of splashing droplet. The simulation results show that:The blowing process has an evidently unstable characteristic,and the cavities are choppy. This transient characteristics govern the generation of metal droplets and their initial spatiotemporal distribution. The splashing occurrence of droplet has two mechanisms:one is the tearing of metal sheet at the cavity edge,and the other is the direct ejectment of single droplet at the cavity edge. Blowing number fluctuates during process due to the oscillating nature of cavity,and an averaged value of 10. 0 for blowing number and 34. 4 kg·m-3 for the splashing rate are obtained under the present blowing condition.关键词
