Plasma cutting machine with different working gases can cut a variety of oxygen cutting difficult to cut metal, especially for non-ferrous metals (stainless steel, carbon steel, aluminum, copper, titanium, nickel) cutting effect; its main advantage is that the cutting thickness is not When the metal is large, the plasma cutting speed is fast, especially when cutting ordinary carbon steel sheets, the speed can reach 5-6 times of the oxygen cutting method, the cutting surface is smooth, the heat deformation is small, and there is almost no heat affected zone.
The plasma cutting machine has been developed to the present, the working gas (the working gas is the conductive medium of the plasma arc, and the heat carrier, and the molten metal in the slit is also excluded). The cutting characteristics of the plasma arc, as well as the cutting quality and speed. There is a clear impact. Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor, and certain mixed gases.
Plasma cutting machines are widely used in automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, engineering machinery, steel structures and other industries!
A safe, simple, effective, versatile and environmentally friendly method for the thermal processing of metals with a thickness of 0.3 mm or more (cutting, welding, brazing, quenching, spraying, etc.) by obtaining plasma from water vapor. The history of the processing industry is the first.
The plasma product "Multiplaz 3500" consists of a plasma gun and a chassis with a total weight of 9 kg. The essence of the working process of the plasma device is as follows: An arc is generated between the inner nozzle (anode) of the gun and the electrode (cathode), so that the moisture between them is ionized to reach the state of the plasma. At this time, the ionized vapor is ejected into the nozzle in the form of a plasma jet by the pressure generated internally, and the temperature is about 8 000 ° C. This cuts, welds, welds and other forms of heat treatment of non-combustible materials.
