Casting pin rail is an important part of coal mining equipment used for the travelling track of coal mining machine, which is usually made of ZG30SiMn material and tempered by heat treatment to enhance its performance. The following is a detailed introduction to casting pin rail:
I. Material and heat treatment
- Material: casting pin rail is generally made of ZG30SiMn material, this material has good mechanical properties and processing performance, suitable for the manufacture of parts subject to large loads and wear.
- Heat treatment: after casting the pin rail needs to be tempered heat treatment, in order to improve its comprehensive mechanical properties, including strength, toughness and wear resistance.
Use and classification
- Usage: Casting pin rail is mainly used in the travelling track of coal mining machine, which is a part of the comprehensive mining scraper, located on the metabolism seat on the baffle groove gang of the scraper.
- Classification: According to the different use scenarios and coal mining machine equipment, casting pin rail can be divided into a variety of specifications and models. Common specifications include 1254, 1255, 125*6, etc. These specifications indicate the cross-section size of the pin rail.
Features and Advantages
- Economy: Compared with forged pin rail, casting pin rail has lower manufacturing cost, which is suitable for light or small coal mining equipment.
- Processing performance: the material and heat treatment process of casting pin rail makes it has better processing performance, which is convenient for subsequent processing and installation.
Application and Precautions
- Application: Casting pin rail is widely used in coal mining equipment, which is an important part to ensure the normal operation of coal mining machine.
- Precautions: When using the casting pin rail, it is necessary to pay attention to its installation position and direction to ensure that it can correctly guide the walking of the coal mining machine. At the same time, it is necessary to regularly inspect and maintain the casting pin rail to find and deal with potential problems and hidden dangers in time.
In summary, casting pin rail is one of the indispensable parts of coal mining equipment, its material, heat treatment, use and classification have certain characteristics and advantages. When using it, you need to pay attention to related matters to ensure its normal operation and extend its service life.
