The invention provides a bell-type furnace capable of being used for local heating. The upper face of a furnace body and the
lower face of the furnace body are respectively provided with a spring, a
copper bar provided with
silicon carbide rods is arranged in the furnace body, the
silicon carbide rods are connected with the
copper bar through conductive strips, a
handle is installed on the side face, facing outwards, of the
copper bar, the portions, at the two sides of the
handle, of the copper bar are further provided with two hangers, the
handle penetrates through the furnace body, and a sealing clamping groove capable of enabling the handle to slide is formed in the furnace body. Due to the fact that the handle is arranged on the copper bar, the position of the copper bar can be shifted through the handle. Therefore, motion of a
heating element is achieved, after movement, the furnace body is sealed through the springs and a clamping device of the sealing groove, when an article needs to be sintered for multiple times, the trouble that the article needs to be taken out and placed in repeatedly is avoided, and the requirement for industrial
mass production is satisfied.
