Abstract

The invention discloses a metal cutting gas, composed of fuel gas and a synergistic agent, wherein the synergistic agent is composed of aluminium carbide, ferrocene, methyl alcohol and MDPE (medium density polyethylene). The metal cutting gas disclosed by the invention has high combustion temperature and good cutting quality and can be completely combusted in the air, the combustion efficiency of the metal cutting gas in oxygen is higher, the temperature can reach about 3300 DEG C, the cutting accuracy is higher, and the grinding process is reduced, thus the product quality is improved; the environmental pollution is less, and extremely less CO or SO2 is produced, thus pollution is greatly reduced; air sources are wide, the application is safe, and the tempering rate is extremely low when the cutting gas is used, thus being very safe; the cutting gas is lighter than air and can directly enter a room to carry out welding and cutting; and the application scope is wide, the selection range of the fuel gas in the cutting gas is wide, and the requirement to the purity of each fuel gas is low.

Description

technical field [0001] The invention relates to a metal cutting gas. Background technique [0002] At present, the main fuel gas for metal welding and cutting is oxygen-acetylene gas. It has contributed greatly to industrial progress and technological innovation since its inception. However, because acetylene gas is flammable and explosive, the safety factor is low, the production process consumes energy and electricity, pollutes the environment, and the production cost is high. Therefore, there are many defects and hidden dangers in production, storage, transportation, use, environmental protection and price, and the development has been greatly restricted. Therefore, there are some cutting alternative gases for acetylene gas, such as "natural gas", "propylene gas", "liquefied petroleum gas" and so on. However, compared with acetylene gas, these substitutes have more or less defects such as insufficient cutting temperature, poor cutting quality, and insufficient combusti...
