Abstract
The invention relates to a fuel for metal industry, in particular to a widely-used energy-saving metal welding and cutting gas which comprises liquefied petroleum gas. The welding and cutting gas is characterized by also comprising an additive and being prepared from the following materials in portions by weight: 3-10 portions of potassium permanganate, 6-15 portions of oxydol, 0.5-2 portions of swelling agent, 1-8 portions of camphene, 1-10 portions of dimethyl ether, 1.5-4.5 portions of ferrocene, 35-55 portions of dichloromethane and 800-1300 portions of water. The welding and cutting gas can be used for multiple operations such as welding of metal cut and brazed pipelines, heat straightening, beveling, spraying, quenching, metal surface heat treatment and the like, has better performance than acetylene in the aspects of welding copper, aluminum and other non-ferrous metal, and can carry out the cutting operation in water. The steel cylinder has the advantages of small volume and light weight, thereby facilitating field operation. Besides, the welding and cutting gas can be used for cutting a rusty steel plate with a thick oxide layer without detonation and tempering, and achieves the characteristics of wider kerfs, high cutting quality and flat and smooth cut surface.

Background technology
Many weeks, cutting is the first working procedure of welding, and the height of cutting section quality, cutting efficiency and material use efficiency all directly affects quality of welded and production cost, and therefore cutting is the important process that welding is produced.Common used acetylene, propane or other industrial combustion gas, but adopt these gas cost height, easily blast, the easy detonation of use, tempering, and cut seam than broad, and can not cut the very thick steel plate of zone of oxidation, cutting quality is poor, cut surface is smooth inadequately bright and clean.
Summary of the invention
The present invention is proposed by addressing the above problem, and provides a kind of and is applicable to that metal cuts, the soldering pipeline welding, heating straightening, bevelling, spraying, quenching, not detonation, no black smoke, not tempering, safe in utilization, the cutting slit is narrow, cheaply energy-saving metal welding and cutting gas.
Technical scheme of the present invention is: energy-saving metal welding and cutting gas, comprise liquefied petroleum gas (LPG), it is characterized in that adding following additives, it is to count ratio by following raw materials in parts by weight to be prepared from: potassium permanganate: hydrogen peroxide: swelling agent: camphor spirit: dme: ferrocene: methylene dichloride: water=3～10: 6～15: 0.5～2: 1～8: 1～10: 1.5～4.5: 35～55: 800～1300.
Described energy-saving metal welding and cutting gas is characterized in that additive counts ratio by following raw materials in parts by weight and be prepared from: potassium permanganate: hydrogen peroxide: swelling agent: camphor spirit: dme: ferrocene: methylene dichloride: water=5～8: 8～11: 1～1.5: 2～6: 3～9: 2.5～3.5: 40～50: 900～1200.
Described energy-saving metal welding and cutting gas is characterized in that additive counts ratio by following raw materials in parts by weight and be prepared from: potassium permanganate: hydrogen peroxide: swelling agent: camphor spirit: dme: ferrocene: methylene dichloride: water=7: 10: 1.5: 5: 6: 3.5: 45: 1100.
Described swelling agent is a hydrogen peroxide.
The main raw material role: potassium permanganate is the intense violet color crystal, and solid is emitted oxygen water 200 ℃ of dispersions, and the aqueous solution is red-purple, and is very unstable, and lentamente but decompose significantly, light has katalysis to its decomposition in acidic solution.
Hydrogen peroxide is water white liquid, pure hydrogen peroxide be in nattier blue thick liquid, can be miscible arbitrarily with water.
The compound method of energy-saving metal welding and cutting gas is as follows:
1) choose raw material by above mass parts and earlier ferrocene is dissolved in the methylene dichloride, the gained solution A that stirs is standby;
2) standby with making solution B after all the other raw materials mixing again;
3) above-mentioned solution A, B are charged into the sky oxygen bottle, and poured into liquefied petroleum gas (LPG) in 24～48 hours, the instrument model that is used the cutting torch regulation is used.
Energy-saving metal welding and cutting gas of the present invention is applicable to that metal cuts, the soldering pipeline welding, the heating straightening, bevelling, spraying is quenched, several work such as metallic surface thermal treatment, welding non-ferrous metal copper, aluminium etc. are better than acetylene, and can cut in water, the steel cylinder volume is little, and is in light weight, makes things convenient for field work, can cut the very thick rust steel plate of zone of oxidation, not detonation, not tempering, and cut seam than broad, cutting quality is good, cut surface is smooth bright and clean.
