Abstract

Abstract: The effect of location and number of gas permeable brick and bottom argon supply rate on mixing time of liquid in a 90 t ladle furnace at steelworks has been tested and studied by using water model with 1：2.5 geometric resemble scale. Results show that the optimum ladle furnace gas permeable brick is located under dumping area of high level charging hopper, the slag material and alloy is directed adding at bare area to get higher melting rate and alloy yield； and the mixing time o£ liquid in ladle is shortest with bottom gas blowing rate 23. 89 L/min, it is available to deep desulphurization of liquid steel.

Key words: Ladle Furnace, Bottom Blowing Process, Mixing Time, Water Modelling

摘要： 采用1:2.5几何相似比的水模型,试验研究了钢厂90 t钢包炉(LF)透气砖位置、数量和底吹供气量对钢包内流体混匀时间的影响。结果表明,优化后的钢包透气砖位于高位料仓下料位置的下方,渣料和合金能够直接加在裸露区,熔化速度快,合金收得率高;底吹气体流量23.89 L/min时钢包流体混匀时间最短,有利于钢水深脱硫。
