Abstract

The invention relates to a fuel gas for welding cut that is environmental friendly and energy saving, in particular to a fuel gas that can substitute acetylene gas. The fuel gas comprises a propane gas, which is characterized in that synergist is added in certain proportion in the propane gas; the content of the propane gas is 97-99%; the content of the synergist is 5 per mill-1%, the content of the liquefiable foreign matter of gas is less than 2.5% by weight; the synergist is a mixed solution comprising combustion catalyst, smoke-removing agent, polymer degrading agent, solvent, solution assistant, and combustion assistant, etc.; the fuel gas is used as combustion gas in place of acetylene gas to weld and cut metals. The flame of the fuel gas is of high temperature, is free from reverse (return) combustion; the fuel gas is of very low explosion limit and low toxicity, free from harm to human bodies, of low comprehensive cost, high efficiency, is safe, environmental friendly and energy saving.

Description

technical field

[0001] The invention relates to an environment-friendly and energy-saving welding and cutting gas, in particular to a gas that can replace acetylene gas in the process of metal welding and cutting. Background technique

[0002] In the machinery manufacturing industry, the technology of welding and cutting metals with oxy-acetylene flames has a long history; this oxy-acetylene welding and cutting technology has some shortcomings, which people have long wanted to solve ;, such as: use acetylene as gas, which is flammable, explosive, and pollutes the environment, and has high cost and high energy consumption. At the same time, acetylene gas contains toxic gases such as phosphine and arsine, which will bring harm to people. harm. With the development of productivity and social progress, people pay more and more attention to environmental protection, energy saving, safety, and efficiency. Acetylene gas has exposed various disadvantages: high energy consumption, l...
