Embodiment 1

[0012] Embodiment one: take by weighing methanol 0.7kg, n-butanol 2.8kg, sherwood oil 1kg, ferrocene 0.5kg, fully mix it, make synergist, then synergist by 5% of the weight of liquefied petroleum gas % injected into the special steel cylinder after the air has been exhausted, then poured into the liquefied petroleum gas, and after shaking well, it is the mixed welding and cutting gas of the present invention.

Embodiment 2

[0013] Embodiment two: take by weighing methanol 1.2kg, n-butanol 1.8kg, sherwood oil 1.9kg, ferrocene 0.1kg, it is fully shaken up, makes synergist, then synergist by the weight of liquefied petroleum gas 5% is injected into the special steel cylinder after exhausting the air, then poured into liquefied petroleum gas, and after shaking well, it is the mixed welding and cutting gas of the present invention.

Embodiment 3

[0014] Embodiment three: take by weighing methanol 1kg, n-butanol 2kg, sherwood oil 1.75kg, ferrocene 0.25kg, it is fully mixed, makes synergist, then synergist by 5% of liquefied petroleum gas weight Inject into the special steel cylinder after the air has been exhausted, then pour into the liquefied petroleum gas, after shaking well, it is the mixed welding and cutting gas of the present invention.

Abstract

The invention discloses a mixed welding and cutting gas, comprising the following ingredients by weight percent: 94%-96% of liquefied petroleum gas or natural gas or propane gas, 0.6%-1.8% of alcohol, 1.6%-2.9% of n-butyl alcohol, 0.09%-0.6% of ferrocene, and 0.4%-2.1% of petroleum ether. The mixed welding and cutting gas takes natural gas or propane gas or liquefied petroleum gas as a basic master batch and a certain amount of a synergist is added to the basic master material, thus the mixed welding and cutting gas has the advantages of high temperature, high combustion value, full combustion, regular flame shape and the like, is easy to control and is an ideal substitute for acetylene gas.

Description

technical field [0001] The invention relates to a mixed welding and cutting gas for metal welding and cutting. Background technique [0002] Most of the traditional gas used for metal welding and cutting in the industry uses acetylene gas, but acetylene gas is expensive, explosive, and low in safety factor. The production process consumes energy and pollutes the environment. Due to the high carbon content of acetylene, it is difficult to control the mixing ratio with oxygen during use, and it is easy to generate black smoke, the combustion state is unstable, and the combustion temperature is also unstable. There are a large number of covalent bonds in the molecular structure of acetylene, and these covalent bonds are agglomerated with each other to form molecular clusters, which makes the acetylene gas not fully combustible, affects the use effect, and has a great adverse effect on metal welding and cutting. Therefore, there are many defects or hidden dangers in the product...
