Hot continuous rolling production method of stainless steel composite board strip coil

The invention provides a hot continuous rolling production method of a stainless steel composite board strip coil. Stainless steel composite board blank is conveyed to a heating furnace to be heated, after undergoing regular rough descaling, conveyed into a roughing mill to undergo five-pass rough rolling and further conveyed to a hot rolling box to be unrolled, the head end of the stainless steel composite board blank and the tail end of the stainless steel composite board blank are cut, after secondary oxide skin is removed through fine descaling, the stainless steel composite board blank is conveyed into a finishing mill to undergo continuous finishing mill and then conveyed into a recoiling machine after undergoing laminar flow water spray cooling, and the stainless steel composite board strip coil is obtained through recoiling. The obtained stainless steel composite board strip coil has a better board shape and better surface quality, meanwhile, has high strength and plasticity, the mechanical property of the product can completely meet the current national standard, and meanwhile, the hot continuous rolling production technology has the advantages of being high in working efficiency, high in material yield and low in energy consumption. The hot continuous rolling production method of the stainless steel composite board strip coil effectively solves the problem of the bottleneck limit of current stainless steel composite board thin gauge products, and thinner gauge stainless steel composite board hot rolls can be developed by the utilization of the peculiarity advantages of stainless steel composite boards.
