摘　　要：通过中厚板中间冷却装置(IC)对粗轧后的中间坯进行强制冷却,可以增加待温过程的冷却速率,提高轧制效率。国内某中板厂原IC装置存在冷却强度低,冷却均匀性差等问题,影响中间坯冷却的使用效果。为此设计了新型IC装置,布置于粗轧机后输出辊道,采用浊环低压供水,冷却区长度6.4 m,92 mm中间坯最大单道次冷却最大温降超过50℃。改造后有效解决改造前存在的冷却能力不足,冷却不均匀等问题,提高生产效率。The cooling rate and rolling efficiency can be increased by forced cooling of the intermediate billet after rough rolling through the intermediate cooling device(IC).The problems of low cooling strength,poor cooling uniformity and so on exist in the original IC device of a domestic medium plate factory,which affect the cooling effect of the intermediate billet.For this purpose,a new type IC device is designed,which is arranged on the output roller table after roughing mill,and adopts turbidity ring low pressure water supply.The cooling zone length is 6.4 m,and the maximum single pass cooling temperature drop of 92 mm intermediate billet is more than 50℃.After the transformation,the problems of insufficient cooling capacity and uneven cooling before the transformation can be effectively solved,and the production efficiency can be improved.
