热带钢轧机工作辊热磨制度

Hot Grind Schedule of Work Roll in Hot Strip Mills

摘要: 热磨制度包括工作辊的下机待磨冷却时间及相应的磨削补偿辊形;在分析了整个轧制过程中和轧制结束后工作辊的温度场和热辊形的变化规律的基础上,建立了热带钢轧机工作辊的热磨制度,认为工作辊的下机最佳冷却时间约为2h,其补偿辊形视磨削后待上机时间而定.

Abstract: The hot grind schedule of work roll in hot strip mills includes the cooling time waiting for grinding after rolling and corresponding compensatory contour. On the basis of analysis of varying rules of work roll thermal field and thermal contour during rolling and after rolling, the hot grind schedule is establish-ed. The optimum cooling time of work roll after rolling is about two hours and its compensatory contour varies with the latency time after grinding.
