1. Points to pay attention to when cutting forgings
Due to the thicker oxide scale on the surface of the forging and the fact that the ignition point of the oxide scale is higher than the melting point, cutting interruptions are likely to occur during cutting. Therefore, first remove the oxide scale on the upper and lower surfaces of the cutting area before cutting.
2. The main points of controlling the deformation of the workpiece
Reasonable arrangement of gas cutting route can effectively control workpiece deformation
3. Important points for thick plate cutting
In thick plate cutting, the temperature decreases from the top surface down. At the beginning of the cutting, the oxygen pressure is gradually increased, and finally reaches a uniformity in the thickness direction of the steel plate.
