The invention provides a hot-rolled steel plate production device. The hot-rolled steel plate production device comprises a raw material box, a feeding pipe, a return pipe, a bracket, a filter treater, a mixing box, a motor and a forging box; the raw material box is mounted in the upper side position of the left end of the return pipe through the feeding pipe; the return pipe is mounted on the bracket; the filter treater is mounted from the left end of the return pipe by 150 cm; the mixing box is mounted on the right side of the filter treater; the motor is mounted on the right side of the mixing box; and the forging box is mounted at the right end part of the return pipe through a bolt. Through settings of the raw material box, the filter treater and the mixing box, the hot-rolled steel plate production device facilitates to add the use functions and guarantee the production efficiency; and through settings of the fine filter screen, a fastening piece and an impurities box, the hot-rolled steel plate production device facilitates to solve the problem of generation of impurities in forging due to filtration not in time, is more convenient to use, and is convenient to popularize and use.
