How to determine the specific model of wear-resistant steel NM400 in the application of building mat

The specific model of wear-resistant steel NM400 for application in the building materials industry can be considered from the following aspects:

1、 Consider the usage environment and degree of wear and tear

Material characteristics:

The material characteristics involved in different building material production processes vary. For example, in cement production, materials may include limestone, clay, clinker, etc. These materials have high hardness and can cause significant wear and tear on equipment during transportation and processing.

If the material contains more hard particles or sharp edges, the wear and tear on the equipment will be more severe. In this case, it is necessary to choose the NM400 model with higher hardness and better wear resistance.

Working conditions:

The working conditions of equipment in the building materials industry are also different.

For equipment working in high-temperature environments, it is necessary to choose the NM400 model with good heat resistance to ensure that it can maintain good hardness and wear resistance at high temperatures. For equipment components that bear significant impact loads, such as jaw plates and hammer heads of crushers, it is necessary to choose the NM400 model with good toughness to prevent fracture under impact.

2、 Reference equipment requirements and design parameters

Equipment type:

When selecting the specific model of NM400, it is necessary to choose suitable wear-resistant steel performance parameters based on the type and working characteristics of the equipment. For example, for crushers, the NM400 model with higher hardness and better toughness can be selected to improve the service life of the jaw plate and hammer head. For conveying equipment, the NM400 model with moderate hardness and good friction resistance can be selected to reduce the operating cost of the equipment.

Design lifespan:

The design lifespan of building materials equipment is also an important reference factor for selecting wear-resistant steel models. If the design life of the equipment is long, it is necessary to choose the NM400 model with higher quality and better wear resistance to ensure that the equipment can maintain good performance throughout its entire service life cycle.
