Induction diathermic furnace

Abstract

The invention provides an induction diathermanous furnace, both an upper supporting body and a lower supporting body of a grate are formed by the welding of square tubes and in pane trench type structure; the trench type structure of the upper supporting body is internally distributed with a left rib plate and a right rib plate which are respectively welded with a channel steel; the trench type structure of the lower supporting body is also internally distributed with the left rib plate and the right rib plate which are also respectively welded with the channel steel; the center part of the bottom of the trench type structure of the lower supporting body is also welded with the channel steel; the five channel steels are uniformly distributed with magnet yokes, an induction coil surrounds the excircle of furnace lining to form a whole and is laid on the magnet yoke inside the lower supporting body, the upper supporting body and the lower supporting body are combined and tightly locked to cause the magnet yoke of the upper supporting body and the magnet yoke of the lower supporting body to form quincunx butt clamping to the induction coil; furthermore, both front and rear end plates are provided with crevasses. The structure has higher strength and rigidity, convenient installation, maintenance and use, beautiful overall appearance and excellent function, and is widely applicable to the forge piece heating.

Description

technical field [0001] The invention relates to a heating furnace, in particular to a power frequency induction diathermy furnace for large-diameter workpieces, and belongs to the technical field of heat treatment equipment. Background technique [0002] At present, the intermediate frequency induction diathermy furnace used for heating forging materials in forging processing technology is composed of furnace frame, furnace shell, furnace lining, water inlet pipe, water outlet pipe, front and rear pressure plates, and sensors. Among them, the furnace frame is generally a steel structure frame, which is mainly used to install the induction coil and the yoke, and bear the load of the furnace lining and the workpiece, so it requires high strength, good rigidity, and good heat dissipation; while the furnace shell is usually laminated on the bottom of the furnace with steel plates It is welded on the steel frame. However, the known public furnace shell is mostly a tubular structu...

Problems solved by technology

Among them, the furnace frame is generally a steel structure frame, which is mainly used to install the induction coil and the yoke, and bear the load of the furnace lining and the workpiece, so it requires high strength, good rigidity, and good heat dissipation; while the furnace shell is usually laminated on the bottom of the furnace with steel plates It is welded on the steel frame. However, the known public furnace shell is mostly a tubular structure spliced ​​with multiple arc-shaped steel plates, which is sleeve-welded on the steel frame at the bottom of the furnace. The strength and rigidity of the similar furnace shell itself are low, and the reinforcement effect on the overall structure of the large-scale intermediate frequency furnace is limited; at the same time, the cylindrical structure of this type of furnace shell makes it difficult to maintain the internal induction coil and yoke. The overall installation of the furnace is cumbersome and difficult
