1150初轧机轧辊温度场分析和冷却效应研究

Analysis on temperature fields and study on cooling effect of the roller in 1150 versatile blooming mill

本文针对1150万能板坯初轧机轧辊冷却效果不佳造成的使用寿命的问题，对轧辊的热传导和冷却效应进行了分析和研究，采用有限差分法对轧辊在轧制过程中的瞬态温度场进行了数值模拟，研究了在3种不同的冷却方式下轧辊的温度场，从中找到了较好的冷却方式。

The heat-conduction and roller-cooling efficiency are analysed, accordingto shorter life-span of the roller during rolling in the 1150 versatile slabbing-bloomingmill. Finite difference method is used to do numerical simulation of twinkling temperature fields. Temperature fields are studied in different cooling conditions, thus a bettercooling condition is found.Weywords:hot-rolling mill, roller, temperature field, cooling
