Heat treatment pipe type furnace

Abstract

The invention provides a heat treatment pipe type furnace which comprises a heating piece, a furnace tube, a first support, a drive device, an object carrying container, second supports, a bearing, a first set of magnets and a second set of magnets. The furnace tube is connected with the heating piece. The first support is fixed to a mounting foundation and fixedly connected with an outer ring of the bearing. An inner ring of the bearing is arranged on the furnace tube in a sleeving manner, and a gap is reserved between the inner ring of the bearing and the outer wall of the furnace tube. The first set of magnets are distributed on the periphery of the inner ring. The drive device is connected with the inner ring to drive the inner ring to rotate around the furnace tube. The object carrying container is arranged in the furnace tube through the second supports. An inner cavity of the object carrying container is communicated with an inner cavity of the furnace tube. The portions, connected with the inner wall of the furnace tube, of the second supports are provided with idler wheels. The second set of magnets are connected with the second supports and distributed along the inner wall of the furnace tube in the peripheral direction. The second set of magnets and the first set of the magnets are oppositely distributed and are different in polarity. By means of the scheme, the problem that an object to be processed makes contact with the air due to stir-frying operation of an operator, thermal treatment cannot be conducted in the set environment is solved.

Description

technical field [0001] The invention relates to the technical field of heat treatment, and more specifically, relates to a tube furnace for heat treatment. Background technique [0002] In the field of mechanical processing, some materials or workpieces usually need to undergo heat treatment to change their properties in certain aspects. In the process of heat treatment, the operator needs to first heat the material or workpiece to a suitable temperature in a medium such as atmosphere or oil, then keep it at this temperature for a set time, and finally cool it at a certain cooling rate. It can be seen that heating, heat preservation and cooling are three essential processes of heat treatment, among which, the uniformity of heating is an important guarantee of heat treatment quality. [0003] In the field of powder metallurgy, the early modification or pretreatment of the powder through heat treatment will have a huge impact on the performance of the workpiece produced later...
