120 t转炉出钢制度的优化研究

Study on Optimization of Steel Production System of 120 t Converter

以120 t转炉为研究对象,对转炉出钢制度进行了优化,使用Gambit、Fluent软件,并结合人工计算,研究了出钢时间、优化了出钢制度。对直径160 mm出钢口出钢操作制度优化后,出钢时间约为269.4 s,较传统出钢制度降低60 s左右。同时通过计算发现,120 t转炉出钢角度不会超过102°。大幅提高转炉出钢效率,降低钢水温降,改善转炉高温出钢的问题,避免造成能源浪费。

A 120 t converter of one steel plant is taken as the study object,the steel production system of the converter is optimized by using of Gambit,Fluent software,and combining with manual calculations to study steel tapping time,to optimize steel production system.After optimization of steel production outlet with 160 mm diameter,the steel tapping time is about 269.4 s,it is 60 s lower than traditional steel production.At the same time,we found the steel tapping angle of 120 t converter is less than 102°.The steel tapping efficiency of converter was increased greatly,the molten steel temperature was decreased,the problems that high temperature steel tapping was improved,therefore the energy wastes can be avoided.
