In recent years, we have seen the rapid development of science and technology in our great motherland. This made me feel extremely proud for me as a Chinese. With the advancement of technology and the progress of people, we will join the Chinese cutting machine trading network to make progress together. Join the hotline, we look forward to your call. Details:/ The problem of cutting slag by gantry cutting machine In the cutting process, the slag phenomenon similar to the flame cutting occurs from time to time. In addition to affecting the appearance of the part, it may even cause the deformation of the outer surface of the material, and it is not possible to perform Secondary processing. CNC Technology Co., Ltd. found in many years of cutting machine production and research and development work, the main cause of the slag problem lies in cutting oxygen pressure or cutting nozzle fittings are not prone to cross-section slag defects, resulting in the cutting section on the lower or the edge of the difficult Cleared slag does not only affect the surface finish. Below, we will analyze and deal with the phenomenon of slag on flame cutting section, which is convenient for users to refer to: Fecal Spreader,Large Farm Manure Spreader,Manure Spreader,Small Manure Spreader Gongzhuling Huaxi Agricultural Machinery Manufacturing Co.LTD , https://www.hxzbjx.com
In general, the slag slag at the flame cutting section is due to insufficient cutting oxygen pressure. The specific performance is to cut the slag on the upper or lower edge of the cutting section. The specific explanation will be given below.
The so-called bottom slag is a continuous slag at the lower edge of the cut section. There are three main reasons for this:
1. The cutting speed is too fast or too slow, the torch number used is too small, and the cutting oxygen pressure is too low;
2. Preheat the excess gas in the flame, and the surface of the steel plate is rusty or unclean;
3. The height between the cutting nozzle and the workpiece is too large and the preheating flame is too strong.
The so-called slag on the cut section means that there is slag on the cut section, especially in the lower part.
