With the maturity and improvement of CNC flame cutting machine technology in recent years, the cutting fuel selection range of CNC cutting machines has become more and more extensive. In addition to conventional fuels such as propane and acetylene oxygen, such as gasoline, liquefied gas, natural gas, etc. Unconventional fuels have gradually become the choice of many enterprises and users. Which manufacturer of CNC cutting machine is better? Dezhou Xi'en CNC Equipment Co., Ltd. The composition of the liquefied gas is complex, the flame is not concentrated during combustion, the heat is uneven, the flame temperature is low, the cutting preheating time is correspondingly increased, the cutting speed is reduced, and the efficacy is poor. So what are the characteristics of this type of unconventional flame cutting fuel, and what are the places to pay attention to during the cutting process? Texas Sean CNC will answer your questions one by one.
liquefied petroleum gas
Liquefied petroleum gas comes from refinery gas, wet natural gas or oil field associated gas.
Natural gas is a multi-component mixed gas. The main component is alkanes, of which methane is the majority, and a small amount of ethane, propane, and butane. In addition, it generally contains hydrogen sulfide, carbon dioxide, nitrogen, and water vapor. And trace amounts of inert gases, such as helium and argon. Under scale conditions, methane to butane exist in a gaseous state, and liquids above pentane are liquid. The main components of liquefied petroleum gas obtained from natural gas and associated gas are propane (the main component commonly known as raffinate), butane, butene, and a small amount of pentane. When cutting thick steel plates to obtain the required total heat, the gas consumption is large. To maintain the speed of portable CNC cutting machines, thick and large components require high external flame heat output, the slits can be easily widened, and the heat-affected zone is large. When preheating the perforation, it is easy to be reversed or difficult to penetrate, which affects the metal surface. Additives to increase flame temperature.
Because the natural gas has a low calorific value, slow burning speed, low flame temperature, the cutting preheating time increases correspondingly, the amount of gas and oxygen consumed is large, and the overall cost is relatively high.
