Alloy steel casting heat treatment process Jul 21, 2017

Alloy castings in the casting process will have a lot of attention to the points and details, we in the process of heat treatment must pay attention to its many things, alloy steel casting heat treatment process under normal circumstances can be effective points For its three stages, heating, heat and cooling.

The same time as the above-

There are three ways in the process of heat treatment. The mechanical properties of the three methods are different in the process of annealing, normalizing, normalizing and tempering. In the course of use, Too complex and wall thickness is not too thick cast steel joints are most commonly used is normalizing.

The same time as the above-

Alloy cast steel in the use of the shape of complex and easy to deformation and cracking of the cast steel joints in the use of the process of using its annealing is more appropriate, normalizing and tempering for thicker carbon steel castings and Low alloy steel, the main purpose of its tempering is to eliminate the stress of the steel joints.

The same time as the above-

Alloy cast steel in the heat treatment temperature and time of choice is a very critical part of the majority of foundry production of alloy steel castings by the water after the heat treatment of the factory inspection. In the raw materials of cast steel because it contains a lot of carbide, so toughness is very low, and very easy to break.

The same time as the above-

Alloy cast steel in the process of making the need for its water and heat treatment, the main purpose of the heat is to effectively remove the carbide, the application process in the need to effectively avoid its cast with its A large horizontal plane, the casting structure as much as possible to make it cool when the unimpeded contraction.

The same time as the above-

Alloy cast steel parts of the local thick section, in the course of the use should be used as far as possible its hollow or cast hole structure, in use and to strengthen the ribs appropriate reinforcement, castings on the plane wall of the casting hole, should be reinforced with a flange , To reduce wall thickness.
