摘要
一钢公司1780mm热轧生产线在粗轧机和精轧机组之间增设了具有侧向隔热屏的无芯轴的钢卷转移热卷箱。文章主要介绍热卷箱的设备组成、运行方式及其主要功能。使用热卷箱后可以减少中间带坯的头尾以及宽度方向的温降,缩短粗轧至精轧之间距离和降低中间带坯报废的功能,从而提高产品质量和成材率。
A coreless hot coil box is installed between the roughing and finishing stands of the 1780mm rolling line at Shanghai No. 1 Steel Co. , Ltd. . The structure, related technologies and control principles of the coil box are introduced. After the coil box is put into use, the temperature drop at the head and tail of the transfer slab and along the width direction can be reduced, the distance between the roughing and finishing stands can be shorten, the scrappage of the transfer slab lowered, the product quali ty improved and the rolling yield lifted.
