Tempering Furnace

Abstract

The invention relates to a tempering furnace. The furnace comprises a furnace body, the top of which is provided with a furnace cover, an inner container is arranged in the furnace body, an air circulating and heating device is arranged on the furnace body, and a hearth is arranged at the bottom end of the furnace body. By properly arranging the furnace cover, the inner container, the air circulating and heating device and the like, the tempering furnace provided by the invention achieves omidirectional tempering of a workpiece which is suspended below the furnace cover by the process of uniformly heating, cycling and preheating the gas in the furnace, thus avoiding tempering blind spot in the furnace, obviously decreasing the temperature deviation in the furnace, and effectively improving the tempering quality of the workpiece in the furnace. Moreover, the tempering furnace maximally utilizes the heat created by burning the fuel, and further improves the furnace tempering effect. Thetempering furnace of the invention has the advantages of reasonable and simple structure, low production cost, simplicity of operation, convenience of maintenance, high efficiency and energy conservation, and is suitable for popularization.

Description

technical field [0001] The invention relates to heat treatment equipment, in particular to a tempering furnace. Background technique [0002] With the development of science and technology and the continuous improvement of production equipment, people's requirements for heat treatment technology are also getting higher and higher, and then the requirements for heat treatment equipment are also getting higher and higher. The current tempering furnace is mainly a horizontal tempering furnace, but for some workpieces with long dimensions and high precision requirements, such as linear slide rails, the horizontal tempering workpiece is easy to deform, which seriously affects the tempering quality of the workpiece , so most of these workpieces are tempered in a well-type tempering furnace.

AI Technical Summary

Problems solved by technology

The current tempering furnace is mainly a horizontal tempering furnace, but for some workpieces with long dimensions and high precision requirements, such as linear slide rails, the horizontal tempering workpiece is easy to deform, which seriously affects the tempering quality of the workpiece , so most of these workpieces are tempered in pit tempering furnaces

[0003] At present, when the well-type tempering furnaces on the market are used, the workpieces are directly placed in the furnace for tempering without special structural devices to clamp the workpieces. Uneven heating directly affects tempering quality

Most of the tempering furnaces currently on the market do not have a hot air circulation system. These tempering furnaces have poor temperature uniformity, a wide range of temperature deviations in the furnace, cumbersome operations, high production costs, and cannot meet the heat treatment needs of high-precision products.
