The Nm400 wear-resistant plate is processed and formed by laser, yet many factors can influence the laser bending forming process, including the laser energy input, the geometric dimensions of the bending section, and the material properties. What is the relationship between these factors and the quality of the Nm400 wear-resistant plate?

The nm400 wear-resistant plate, the energy absorbed by laser bending is affected by the energy density and the time it takes to absorb energy. The energy density depends on the material's absorption coefficient of the laser, the surface relative to the bending part, and the laser output power and focal length. Experiments show that heating in a short period of time, under the premise of high energy density input, helps to increase the bending angle of the composite wear-resistant plate. What factors are related to the laser forming effect of nm400 wear-resistant plates?

Next, the thermal and mechanical properties of nm400 wear-resistant steel plate laser bending are relatively complex, primarily affecting parameters such as material thermal expansion coefficient, specific heat capacity, thermal diffusion coefficient, yield strength, and elastic modulus, as well as the hardening index. Under the same process conditions, nm400 wear-resistant steel plates with higher specific heat capacity and thermal conductivity exhibit an insignificant temperature gradient in the engineering, and this is more pronounced with smaller bending angles.
