根据相似原理计算了水模喷吹参数,第一次模拟并拍照了在不同熔池搅拌能量条件下,转炉熔池中废钢运动的实际情况,使炼钢工作者对废钢在熔池中的运动有了清楚的了解。测量了废钢对熔池混匀时间和喷溅的影响,大型转炉炼钢熔池中有10%废钢,熔池混匀时间较无废钢时平均延长35.3%,铁水脱磷预处理转炉有10%废钢,熔池混匀时间平均延长62.8%。定量地研究了熔池中不同质量废钢块与悬浮能量之间的关系,为使废钢熔化有良好的动力学条件,应使熔池的搅拌能量不低于大块废钢的悬浮能量。丰富了废钢熔化的基础知识,为转炉合理地利用废钢和优化转炉吹炼工艺提供依据。
Based on the similarity principle, the water injection parameters were calculated and the actual situation of the scrap movement in the converter pool was simulated and photographed for the first time under the condition of different molten pool stirring energy to make the steelmaker’s movement to the scrap in the melt pool With a clear understanding. The effect of scrap on mixing time and splashing of the molten pool was measured. 10% of the scrap in the large converter steelmaking pool was lengthened 35.3% longer than the average without scrap, 10% Scrap, molten pool mixing time average 62.8% longer. The relationship between the mass of scrap and the suspended energy in the molten pool was studied quantitatively. In order to melt the scrap with good kinetic conditions, the mixing energy of the molten pool should not be lower than the suspended energy of the bulk scrap. Enriched the basic knowledge of scrap melting, to provide a basis for the rational use of scrap steel converter and converter blowing process optimization.
