Abstract
The invention relates to metal cutting gas. The metal cutting gas is prepared from natural gas and additives, and the additives are prepared from p-xylene, ethylbenzene, m-xylene and ferrocene. The cutting temperature of the natural gas metal cutting gas is higher than or equal to that of traditional acetylene gas, cutting quality is good, the source is wide, the preparation cost is low, and using is quite safe.
Description
Technical field
The invention belongs to metal cutting technical field, be specifically related to a kind of metal cutting gas and preparation method thereof.
Background technology
At present, the major gas of metal welding is oxygen-acetylene gas.Namely it make a great contribution to industrial progress and technological innovation at the beginning of using.But because acetylene gas is inflammable and explosive, safety coefficient is low, power consumption of consuming energy in production process, contaminate environment, production cost is higher.So, in production, store, transport, use, environmental protection and there is many defects and hidden danger in price, development receives very big restriction.Therefore occurred that the cutting of some acetylene gass substitutes gas, as " Sweet natural gas ", " propylene gas ", " liquefied petroleum gas (LPG) " etc.But these alternative bodies and acetylene gas more or less also exist by comparison, and cutting temperature deficiency, cutting quality are poor, the defect such as insufficient of burning.
Summary of the invention
The technical problem to be solved in the present invention metal cutting gas cutting temperature is not enough, cutting quality is poor, the technical problem such as insufficient of burning and provide a kind of metal cutting gas, its cutting temperature is not less than traditional acetylene gas, cutting quality is good, and wide material sources, cost of manufacture is cheap, uses very safe.
For achieving the above object, the technical solution used in the present invention is as follows:
The invention provides a kind of metal cutting gas, comprise Sweet natural gas and additive, described additive is made up of p-Xylol, ethylbenzene, m-xylene and ferrocene.
According to above-mentioned metal cutting gas, described additive is made up of following raw material: p-Xylol 50 ~ 60, ethylbenzene 20 ~ 30, m-xylene 10 ~ 15 and ferrocene 1 ~ 2.
According to above-mentioned metal cutting gas, described additive is made up of following raw material: p-Xylol 59.3, ethylbenzene 25.9, m-xylene 13.6 and ferrocene 1.2.
According to above-mentioned metal cutting gas, the purity of described ferrocene is more than 99.9%.
With 1m
3sweet natural gas is benchmark, and the addition of described additive is 3 ~ 5g.
The preparation method of described metal cutting gas, concrete preparation process is as follows:
The preparation of step one, additive: a. first measures p-Xylol, ethylbenzene and m-xylene and mixes and obtain mixed solution a; B. measure 5 ~ 10% mixed solution a, then formula ratio ferrocene is joined 5 ~ 10% mixed solution a and stir and obtain mixture b; Mixture b joins in remaining mixed solution a and mixes by c;
Step 2, to enter additive according to proportioning in tank natural gas liquids, the two dissolves each other standing 10 hours, obtains liquid natural gas metal cutting gas;
Step 3, by the mode being converted into compressed natural gas by natural gas liquids, the liquid natural gas metal cutting gas made is changed into gas phase metal cutting gas for natural gas, to obtain final product.
the invention has the beneficial effects as follows:temperature of combustion is high, and cutting quality is good, and it burns very complete in atmosphere, and the efficiency of burning in oxygen is higher, and temperature can reach about 3300 DEG C, and cutting accuracy is higher, decreases polishing operation, improves quality product; Production cost is low, and due to natural gas wide material sources, price is lower, causes cutting gas can reduce by more than 70% compared to acetylene gas production cost; Contaminate environment is little, and the gases such as CO, SO2 produce few, very big decreasing pollution; Source of the gas source is wide; Use safety, when cutting gas uses, tempering rate is extremely low, very safe, and cutting gas proportion lighter than air, directly can enter indoor and carry out welding operation; Applied widely, the combustion gas range of choice in cutting gas is wide.
