Sand blasting type heat treatment device

Abstract

The invention provides a sand blasting type heat treatment device which comprises a heat treatment furnace and a sand blaster, wherein a rotating platform capable of performing self-axis rotation along a vertical axis is designed at the bottom of the inner chamber of the heat treatment furnace; a metal workpiece to be subjected to heat treatment is fixed above the rotating platform; the sand blaster is fixed on the outer side of the heat treatment furnace; the sand blasting head of the sand blaster penetrates into the heat treatment furnace; a sand storage box is fixed above the sand blaster; the sand storage box is communicated with the sand blaster through a heating box; the sand blaster is connected with a high-pressure gas circuit. The sand blasting type heat treatment device blasts high-temperature and high-pressure grinding sand to the surface of the metal workpiece to grind the surface of the metal workpiece, and simultaneously heats the metal workpiece so as to facilitate the next heat treatment operation on the metal workpiece.

Description

technical field [0001] The invention relates to the technical field of metal heat treatment, in particular to a sandblasting heat treatment device. Background technique [0002] Heat treatment is a metal thermal processing process in which metal materials are heated, kept warm, and cooled in a certain medium, and their properties are controlled by changing the crystal phase structure on the surface or inside of the material. Heat treatment has an excellent effect on solving the surface properties of metal materials. Therefore, in actual production, people often heat treat the surface of metal parts after the parts are produced. Traditional metal heat treatment usually involves people directly heating the parts quickly, and then Let it rest at a higher temperature, and then cool it down quickly. This method of heating metal parts has a single function, which is simply heating, while the energy utilization rate of the heating process is low, and it is usually difficult for t...

AI Technical Summary

Problems solved by technology

This method of heating metal parts has a relatively single function, and it is only for simple heating. At the same time, the energy utilization rate of the heating process is low, and it is usually difficult for the heat to reach the surface of the metal parts evenly during heating.
