New technology of HARDOX 400 wear-resistant plate cutting

Because the HARDOX 400 wear-resistant plate is hard and thick, it is very time-consuming and laborious in the process of cutting, and the material is also wasted, and the cost of the HARDOX 400 wear-resistant plate is greatly increased. So how should we solve this situation?

Generally speaking, the gas with high burning speed and high burning value is suitable for thin plate cutting, and the combustible gas with low combustion value and slow combustion speed is more suitable for thick plate cutting, especially the HARDOX 400 wear-resistant plate with thickness above 200mm. If natural gas is used to cut, the cutting quality will be ideal, only the cutting speed will be met. A little lower. In comparison, acetylene is much more expensive than natural gas. For the former cutting gas, acetylene is the main cutting gas in the production of cutting, but with the change and development of natural gas in the last two years, natural gas is analyzed from a comprehensive point of view, which is more recognized by the market and the state than acetylene. The most important point is that it can save energy and environmental protection. As for its slow cutting speed, a series of problems have also been solved since the advent of natural gas synergist on the market.

The cutting speed of HARDOX 400 wear-resistant plate corresponds to the burning rate of steel in oxygen. In actual production, the cutting speed should be adjusted according to the performance parameters of the cutting nozzle, gas type and purity, HARDOX 400 wear-resistant plate material and thickness. Cutting speed directly affects the stability of cutting process and the quality of cutting section. If you want to improve the cutting speed artificially to improve the production efficiency and reduce the cutting speed to best improve the quality of cutting section, it is not possible to make the cutting section quality worse. Too fast cutting speed will cause quality defects such as sag and slag, which may cause cutting interruption. Too slow cutting speed will make the edge of the cutting edge melted, the lower edge produce round angle, and the lower part of the cutting section appears deep groove, and so on.

In the flame cutting process of HARDOX 400 wear-resistant plate, the height from the cutting nozzle to the cutting surface is one of the main factors that determine the cutting quality and cutting speed. Different thickness of HARDOX 400 wear-resistant plate, using different parameters of the cutting mouth, should adjust the corresponding height. In order to obtain high quality incision, the height from the cutting nozzle to the surface of the workpiece must be basically consistent throughout the cutting process.

So now that there are new technologies for cutting HARDOX 400 wear-resistant plates, the efficiency of production will be improved significantly. On the basis of this reduction, we can also achieve the effect of green environmental protection, energy saving and emission reduction.
