Ladder type supporting seat of compartment type heating furnace

The invention belongs to the technical field of heat treatment, and particularly relates to a box type heating furnace trapezoid supporting seat which comprises a supporting seat body, the supporting seat body comprises an upper top end face and a lower bottom plane, and a cross-shaped supporting structure is arranged between the top end face and the bottom plane; the circulating cooling mechanism is used for cooling the supporting seat main body through circulating water; and the heat absorption mechanism cools the circulating water through the heat absorption characteristic of salt particles, so that the cooling effect of the circulating water on the supporting seat main body is guaranteed. According to the trapezoid supporting seat of the compartment type heating furnace, the supporting seat body is in the isosceles trapezoid shape, the top end face is used for bearing a material tray and parts, the area of the bottom plane is twice that of the top end face, a good stable supporting effect is achieved, the
