The invention provides a rolling device and method for high silicon steel, and belongs to the technical field of rolling of metal strips. A production device comprises a vacuum furnace, a pouring device, a casting rolling machine, a leveling machine, a flying shear, a coiling type warm rolling device, a finished product coiling machine, a dividing shear and a PLC control system. An application method comprises the following steps: (1) preparing materials and pre-heating a rolling line; (2) performing steelmaking and pouring; (3) casting a strip; (4) levelling; (3) cutting a head/ cutting a tail/ shearing into sections; (6) threading the strip; (7) coiling through a right coiling machine; (8) coiling through a left coiling machine; (9) performing warm rolling; (10) collecting finished products. According to the method, the short-process high silicon steel production technology combining the rolling and the warm rolling is adopted, so that the process of a thin high silicon steel plate can be greatly reduced, and as a result, the energy utilization rate is high, the cost is low, and the pollutant emission is reduced; a warm rolling device can perform warm rolling and cold rolling, so that the process technology advantages of the rolling device and the method on the structure performance, surface quality and plate shape in the thin high silicon steel rolling process technology cannot be matched by other material forming process.
