Embodiment Construction

[0009] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0010] The specific method is:

[0011] The thickness of the shot blasting and shot blasting room liner is about 8mm, and the reinforcement design is added, and then the four corners and the middle are clamped with a clamp and placed on a quenching hand plate for heating. In the heating process, it not only straightens the small bending during casting, but also ensures that the workpiece is forced to straighten during quenching, and the effect is very good.

Abstract

The invention relates to a heat treatment method-double compression method for a lining plate of a shot blasting room of a high-chromium iron shot blasting machine. The method specifically comprises the steps that the thickness of the lining plate of a shot blasting and a shot blasting chamber is about 8mm, the design of additionally arranging reinforcing ribs is adopted, and then, a clamp is used for clamping the four corners and the middle of the ribs to put the ribs on a quenching hand disc so as to be heated. In the heating process, the small bend in the casing process is straightened, the forced straightening of mechanic parts during quenching is ensured, and the good effect is achieved.

Description

technical field [0001] The invention relates to the field of heat treatment, in particular to a heat treatment method for the lining plate of a shot blasting chamber of a high-chromium cast iron shot blasting machine—a heavy pressing method. Background technique [0002] Because the workpiece is thin and long, it is easy to deform and warp during casting, especially during heat treatment. Due to the high brittleness of high-chromium cast iron, it cannot be straightened at room temperature, but can only be straightened naturally at high temperature. We adopt the method of hoisting heating and hoisting quenching, which can better solve the problem of deformation, but it cannot solve the problem of high hardness. How to solve the problem of deformation in oil temperature quenching has become a big problem. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a heat treatment method for the liner ...
