The roller way is the main equipment for conveying rolled pieces in a steel rolling workshop, the weight of the roller way accounts for about 40% of the total weight of the whole steel rolling workshop equipment, and the roller way is the most used equipment in the steel rolling workshop. The slab is lifted up to a roller way by a crown block, is conveyed into a heating furnace by a roller, is rolled back and forth on a rolling mill, and is conveyed to a finishing process after rolling, and the like, and the work is completed by the roller way. In particular to a furnace feeding roller way of a heating furnace, which is not only equipment for conveying slabs into the furnace, but also can be used as an extension warehouse of a slab warehouse to relieve the problem of warehouse position shortage during high inventory. At present, due to unbalanced material receiving and feeding structures of a roller way and limited interlocking functions of the roller way, the raw materials are waited for a long time, and the production rhythm is reduced.
