There are many types of industrial gas used for metal cutting, and the more used are acetylene, propane, propylene, and liquefied petroleum gas, while natural gas has only been used in small quantities in recent years. This is mainly due to the relatively short time that natural gas has entered the industrial cutting industry, and people have recognized it relatively late. However, due to the lack of concentration of natural gas flame, the flame temperature as cutting gas is low, the preheating time is long, the speed is slow, and the efficiency is low, so that its wide application in the field of cutting gas is greatly limited.

Natural gas high-energy cutting gas is added to the natural gas with a natural gas synergist that can be completely mixed with it, this natural gas synergist can change the frequency and wavelength of the flame in the combustion state, activate the main medium to burn rapidly, and release higher heat energy, At the same time, it improves the transfer of effective heat to the agent, inhibits the radiation of the flame to the surrounding air, and the temperature reaches 3300 °C. It can cut 6-250 mm steel plate, the surface of the cutting body is smooth and flat, the upper edge has no undercut, the lower edge has no hanging slag, the cleaning is simple and easy, and the surface will not occur carbon deposits and hardening. At present, many industrial enterprises in Hebei, Henan, Shandong, Liaoning, Ningxia, Guangxi, Zhejiang, Guangxi, Jiangsu, Anhui and other places have successfully replaced propane gas and acetylene gas with natural gas high-energy cutting gas.
