How to improve the surface finish of Q235B steel plate?

1. Improve the surface flatness of Q235B steel plate. After molding, the flatness of Q235B steel plate has been improved to a certain extent, and the wave shape of Q235B steel plate has been partially removed. In addition, the surface layer of slag particles or other uneven point-like substances can be flattened to make the surface layer more and more smooth. Thick steel plate.

2. Adjust the surface roughness of the Q235B steel plate surface. According to the surface roughness of the roller surface in the entire mechanical work of operating the light, the original uneven surface roughness of the Q235B steel plate surface can be unified to a certain range.

3. Improve the surface color of Q235B steel plate. For spangled and spangled products, the Q235B steel plate can get a more evenly smooth surface layer according to the casting mold.

4. Improve the processing characteristics of Q235B steel plate. According to the casting mold, the Q235B steel plate processing traces can be faded or not noticeable, and the metal material load line thick steel plate can be avoided in the subsequent processing.
