The invention discloses a bell-type
solid melting furnace which comprises a
portal frame, a furnace body, a trolley and a rail. The
portal frame is arranged across the rail, and a
winch is arranged in the middle of a top beam. The trolley is of a platform lorry structure, the top face of the trolley is provided with a furnace bottom made of fire-resistant materials, the bottom of the trolley is provided with idler wheels, and the trolley moves in a reciprocating mode along the rail due to the fact that a matched speed
reducer drives the idler wheels. The furnace body is made of fire-resistant materials in a coated mode and is of a bell type, a hook on the top of the outer wall forms a lifting mechanism due to the fact that the
winch matched with the
portal frame drags through a steel
wire rope, the furnace body is a container with a downward opening, the opening is matched with the furnace bottom, and the inner wall of a
hearth is provided with a necessary heating device. The furnace body is of a bell type, the opening of the furnace body is matched with the furnace bottom after the hung furnace body is descended, the combination portion is tightly sealed due to the fact that
self weight of the furnace body is large, heat loss does not occur during heating, and meanwhile no air enters the
hearth. Accordingly,
heating efficiency is high, heating quality is good, and oxidation
layers on the surfaces of workpieces are few after heating.
