The plate 15 slides along the reserved groove 13, and can open and close the through hole 18 provided on the inner side of the movable plate 5, so as to facilitate the normal heat preservation and heat dissipation work of the heating area inside the furnace body 1. The outer wall of the baffle 15 is connected with a spring 14, and the other end of the spring 14 is connected with the movable plate 5. One side of the movable plate 5 is connected with a material box 7, and an electric heating wire 8 is installed at the lower inner side of the material box 7. Molten salt or other substances can be contained in the material box 7 to assist in raising the temperature to a certain value, thereby shortening the time required for heat treatment.
