Hot rolling process of stainless plate strip coil

The invention provides a hot rolling process of a stainless composite plate strip coil, which comprises the following steps of: heating and sending a stainless composite plate blank to a steckel mill; flatly rolling: repeatedly carrying out rough rolling for a plurality of times under the conditions that a rolling temperature is 1050-1250 DEG C and the rolling speed is smaller than 12.6 mm/min; then, sending into a coiling furnace; carrying out coil rolling: repeatedly carrying out fine rolling for a plurality of times under the conditions that the coiling furnace temperature is 550-1000 DEG C and the final rolling temperature is 800-1000 DEG C; finally, directly sending the plate blank into a coiling machine or after cooling the plate blank to 450-700 DEG C; and coiling to obtain a thinner and longer stainless composite plate strip coil with better flatness and surface quality and higher strength and plasticity. The invention has high working efficiency, yield rate, low consumption, high automation degree and low production cost, and can roll various types of stainless composite plate strip coils with different thicknesses and sizes in a batch of dozens of tons to several hundred of tons and fully utilize the additional rolling equipment to produce.
