在连续铸轧中 ,金属液经铸嘴装置连续不断地注入 2个相向旋转、内部通水冷却的铸轧辊的辊缝中间 ,金属液在辊缝中冷却、凝固结晶并经轧制成形 .作者通过建立铸坯与铸轧辊辊套之间强温变耦合特性的界面接触热导模型及铸坯和铸轧辊辊套传热数学模型 ,对铸轧辊与铸坯的温度场进行了仿真 ,并分析了辊套的厚度、导热系数和表面粗糙度对辊套温度分布的影响 .通过仿真分析发现 :辊套外表面温度在铸轧区变化剧烈 ,辊套进入铸轧区入口处温度开始急剧上升 ,但最高温度并不在出口处 ,而是在轧制区靠近出口处 .辊套离开铸轧区后温度开始下降 ,进入入口处时温度降至最低 ;界面导热能力随辊套表面粗糙度减小、辊套材料的导热系数增大、辊套厚度减小而增大 . In continuous casting and rolling, the molten metal is injected continuously into the middle of the nip of two oppositely rotating, internally water-cooled casting rolls by means of a nozzle. The molten metal is cooled in a nip and solidified and crystallized and rolled. The temperature field of the casting roll and slab is simulated by establishing the interface contact thermal conductivity model and the heat transfer mathematical model of the slab and the roll shell of the casting roll and the casting roll shell. The influence of the thickness of the sleeve, the thermal conductivity and the surface roughness on the temperature distribution of the sleeve was analyzed.The simulation results show that the temperature of the outer surface of the sleeve changes sharply in the casting zone, the temperature of the roll sleeve entering the entrance of the casting zone begins to rise sharply, But the maximum temperature is not at the exit, but near the exit of the rolling zone.The temperature of the roll sleeve begins to decrease after leaving the casting zone, and the temperature is reduced to the lowest when entering the entrance zone.The interface thermal conductivity decreases with the surface roughness of the sleeve, The thermal conductivity of the sleeve material increases, the thickness of the sleeve decreases and increases.
