Abstract
The invention relates to natural gas metal cutting gas which is prepared from liquefied natural gas and an additive, wherein the additive is prepared from diphenylcarbinol, propylcyclohexanol, tert-butyl methyl ether, methanol, anhydrous ethanol and gasoline. The natural gas metal cutting gas is prepared from the following components in parts by weight: 98.4-98.7 parts of the liquefied natural gas and 1.3-1.6 parts of the additive. The additive is prepared from the following components in parts by weight: 7-30 parts of diphenylcarbinol, 10-20 parts of tert-butyl methyl ether, 40-60 parts of methanol, 2-10 parts of anhydrous ethanol and 3-6 parts of gasoline. According to the natural gas metal cutting gas provided by the invention, the additive and the natural gas jointly take part in combustion reaction in oxygen after the natural gas is liquefied and the natural gas metal cutting gas provides a chemical intermediate for combustion of the natural gas to improve the combustion speed of the natural gas in oxygen so as to improve the combustion temperature; the natural gas metal cutting gas is safe to use, free of tempering if being used for cuing and the like, and moreover, the cutting gas is lower than air in specific gravity, and can be used for indoor operation.
Description
technical field [0001] The invention relates to the technical field of metal cutting, in particular to a natural gas metal cutting gas. Background technique [0002] At present, industrial cutting is still dominated by acetylene gas. However, calcium carbide, the raw material for acetylene production, is obtained through six energy conversions. The average production of 1 ton of calcium carbide consumes 3300-3500kWh of electricity and 1 ton of coke, and its waste residue is harmful to the ecological environment. The serious pollution caused by it has become a social problem of widespread concern. Acetylene gas has high energy consumption, high cost, is flammable and explosive, seriously damages resources, and pollutes the environment. All countries are actively developing new cutting gases and have achieved success. However, most new cutting gases have low combustion temperatures, which affect cutting speed and Quality, the new type of cutting gas is heavier than air and ea...
