热轧带钢是武钢的主要产品,年产300多万吨。在热生产工艺中,板坯经加热炉加热后经大立辊挤压,高压水除鳞,送入四座粗轧机(R_1—R_4)粗轧,最后进
Hot-rolled steel is the main product of Wuhan Iron and Steel, with an annual output of more than 300 million tons. In the heat production process, the slab is heated by a heating furnace and then extruded through a large vertical roller to descale the high-pressure water into rough rolling of four roughing mills (R_1-R_4)
