Hot Grind Schedule of Work Roll in Hot Strip Mills
-
摘要: 熱磨制度包括工作輥的下機待磨冷卻時間及相應的磨削補償輥形;在分析了整個軋制過程中和軋制結束后工作輥的溫度場和熱輥形的變化規律的基礎上,建立了熱帶鋼軋機工作輥的熱磨制度,認為工作輥的下機最佳冷卻時間約為2h,其補償輥形視磨削后待上機時間而定.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.
