Research on thermal deformation control technology of BTW1 wear-resistant steel

In industries such as metallurgy and mechanical engineering, BTW1 wear-resistant steel is widely used due to its excellent corrosion and wear-resistant performance. However, its thermal deformation control technology is not perfect. This article will discuss the main factors affecting the thermal deformation of BTW1 wear-resistant steel and the controlling measures that can be taken to reduce or eliminate thermal deformation.
    
Main Causes of Thermal Deformation of BTW1 Wear-Resistant Steel
The alignment of the structure and the thermal expansion coefficient are the main causes of thermal deformation of BTW1 wear-resistant steel. First, when the structure of the equipment is not aligned, the parts have strong heterogeneity, which causes the equipment to produce thermal deformation. Second, the thermal expansion coefficient of BTW1 wear-resistant steel is large, and when the temperature rises, the deformation of the device components is increased accordingly.
    
Thermal Deformation Control Technology
The control of thermal deformation of BTW1 wear-resistant steel contains two aspects: mechanical properties control and heat treatment process control. In terms of mechanical properties, the control of the organization is important, including the control of the finish of the structure, the improvement of the structure and the selection of materials and the like. In terms of heat treatment, in addition to controlling the temperature, pay attention to the quenching medium and quenching process of the BTW1 wear-resistant steel and the selection of high-temperature tempering medium and temperature control process.
    
    (A) In terms of organization, the control of the finish of the structure can be done by first surface grinding on the surface of the structure, and then high-precision incremental steps can be taken to reduce the alignment error.
    
    (B) In terms of selecting the material, it is best to use BTW1 wear-resistant steel with low thermal expansion coefficient.
    
    (C) Heat treatments include quenching and tempering. In the quenching process, using low-temperature quenching medium such as old oil and brine can reduce the adverse effect of the thermal deformation of the material. During the tempering process, a higher temperature medium should be used to increase the tempering strength and reduce the thermal deformation.
    
Conclusion
To sum up, the thermal deformation of BTW1 wear-resistant steel can be effectively controlled by improving the structural precision, improving the quenching process, and properly selecting the quenching and tempering temperature.
