Embodiment 1

[0017] A metal cutting gas, including natural gas and additives, the amount of additives added to natural gas is 3~5g / m 3 The additive is made of the following raw materials in parts by weight: p-xylene 50-60, ethylbenzene 20-30, m-xylene 10-15 and ferrocene 1-2.

[0018] The preparation method of the metal cutting gas, the specific preparation steps are as follows:

[0019] Step 1, preparation of additives: a. first measure p-xylene, ethylbenzene and m-xylene and mix them uniformly to obtain mixed solution a; b. measure 5-10% mixed solution a, and then add the formula amount of ferrocene to 5~10% mixture a is stirred evenly to obtain mixture b; c. add mixture b to the remaining mixture a and mix well;

[0020] Step 2: Put the additives into the liquefied natural gas in the tank according to the ratio, and the two are mutually dissolved and left for 10 hours to obtain the liquid-phase natural gas metal cutting gas;

[0021] Step 3: Transform the produced liquid-phase natural...

Embodiment 2

[0023] A metal cutting gas, including natural gas and additives, the amount of additives added to natural gas is 4g / m 3 The additive is made of the following raw materials in parts by weight: p-xylene 50, ethylbenzene 30, m-xylene 10 and ferrocene 2.

[0024] The preparation method of this embodiment is the same as that of Example 1.

Embodiment 3

[0026] A metal cutting gas, including natural gas and additives, the amount of additives added to natural gas is 5g / m 3 ; The additive is made of the following raw materials in parts by weight: p-xylene 52, ethylbenzene 28, m-xylene 12 and ferrocene 1.9.

[0027] The preparation method of this embodiment is the same as that of Example 1.

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 [0001] The invention belongs to the technical field of metal cutting, and in particular relates to a metal cutting gas and a preparation method thereof. Background technique [0002] At present, the main fuel gas for metal welding and cutting is oxygen-acetylene gas. It has contributed greatly to industrial progress and technological innovation since its inception. However, because acetylene gas is flammable and explosive, the safety factor is low, the production process consumes energy and electricity, pollutes the environment, and the production cost is high. Therefore, there are many defects and hidden dangers in production, storage, transportation, use, environmental protection and price, and the development has been greatly restricted. Therefore, there are some cutting alternative gases for acetylene gas, such as "natural gas", "propylene gas", "liquefied petroleum gas" and so on. However, compared with acetylene gas, these substitutes have more or le...
