Heat Treatment Process For Heat-resistant Steel Castings Jul 18, 2017



Heat treatment process for Heat-resistant Steel Castings

Heat-resistant Steel Castings is very important in making process. If there is a temperature difference, it will affect the quality of the product. The heat treatment process of heat resistant steel casting is described below.

When the Heat-resistant Steel Castings is formed, let it be treated in a hot stove. The principle of heat resistant casting steel is generally fast and uniform, easy to control and high efficiency and low cost. After heating, the heat preservation process is to be carried out, which is mainly to prevent the Heat-resistant Steel Castings from appearing in the first cold heat. The time of heat preservation is usually about twice as long as the heating time. The next step is cooling, which is also very important for heat resistant steel casting. If there is no timely cooling, it will not affect the toughness of the Heat-resistant Steel Castings. Heat-resistant Steel Castings is often used in cooling process for oil, water, brine and other materials.

Heat-resistant Steel Castings is a part of mechanical equipment, which is very important. If any problem in the production process of the Heat-resistant Steel Castings parts will affect the quality of the Heat-resistant Steel Castings. Today, we will introduce the production process of heat-resistant steel casting.

1. Casting: the raw material is poured into the furnace to melt. In addition to the metal elements, the temperature will reach 1600 degrees, and the melted solution will be poured into the mold shell and cooled.

2. Remove sand from the surface of Heat-resistant Steel Castings.

3. Cutting Heat-resistant Steel Castings with professional instruments.

4. Grinding, polishing the surface of Heat-resistant Steel Castings parts or places with impurities.

5. Heat treatment is also important, to be fired, cooled, tempered tempered, carburized, nitride, etc.

6. Check and use the instrument to check whether the Heat-resistant Steel Castings is defective and qualified.

Packing, after examination, the qualified products can be packed, delivered and sold normally.

After the process of production of Heat-resistant Steel Castings, after the processing of rough processing and anti-rust processing, it can truly be sold to the outside world. The following detailed description of rough processing and rust prevention treatment.

Rough machining: be in heat resistant steel delivery before rough machining, localized after rough machining can timely found the defects of heat resistant steel, and modified, reduce the weight of the heat-resistant steel.

Rust-proofing: to prevent the corrosion of the steel parts in the transportation process. Generally this step is to apply anti-rust material on the product after inspection.

Heat-resistant Steel Castings has the advantages of high hardness, good wear resistance and good shock resistance. It is used in different industries. But when choosing Heat-resistant Steel Castings, buyers must carefully select to prevent their own purchase of Heat-resistant Steel Castings parts that cannot be used properly.

When purchasing a Heat-resistant Steel Castings to see if the surface is incomplete, such as crack, burr, impurities and other issues, the second is to see whether have the problem of decarburization on the product, after is to see how about the hardness of heat resistant steel, Heat-resistant Steel Castings can be gently fell once, see if there is a crack appeared.

Heat-resistant Steel Castings is widely used in the machinery industry, and any quality problems will have a great impact on machinery. Heat-resistant steel casting at the same time there is any quality problem about the quality of the mechanical equipment have very big, Heat-resistant Steel Castings have quality problem will affect the service life of machine tools and precision, and can also affect the mechanical equipment system efficiency, and even will directly affect the work life.
