热卷箱位于热连轧生产线粗轧机和精轧机中间的工艺设备,它将粗轧中间坯卷成热钢卷,然后再开卷送入飞剪及精轧机。生产过程中热卷箱需要与粗轧机形成连轧连卷,又要与精轧机形成连开连轧的工况。处理好热卷箱与轧机的速度匹配关系对稳定生产和提高产品质量至关重要。本文介绍了热连轧机中热卷箱的速度控制及其与轧机和辊道的速度匹配关系。
The hot coil is located in the middle of the hot-rolling mill’s roughing mill and finishing mill. It cools the roughing intermediate into a hot coil, which is then uncoiled into a flying shears and finishing mill. In the production process, the hot coil box needs to form a continuous rolling coil with the rough rolling mill and a continuous rolling operation with the finishing mill. Handling the speed matching between the hot coil and the mill is crucial for stable production and improved product quality. This article describes the speed control of the hot coil box in a hot strip mill and its speed matching with the mill and roller table.
