thermal cutting, plasma cutting in the position

  A kind of thermal cutting method and its application status

Commonly referred to as thermal cutting law mainly refers to cutting, plasma cutting, laser cutting. Rely on the traditional cutting of metal cutting oxidation reaction, so its cutting

Speed ​​is limited by the metal oxidation reaction speeds. Plasma cutting is to rely on electricity for molten metal cutting, laser cutting is to rely on light molten metal to be cut, which

Two kinds of cutting methods to increase its cutting power as long as you can to improve their cutting speed. In cutting areas, in addition to the use of oxygen, gas cutting, the recent German research into

Successful use of liquid oxygen, gas hydraulic cutting machine method to achieve high-energy, greatly improved cutting efficiency, but the cutting machine is expensive, even the industrialized countries should be in production

Rarely used. So it comes to cutting specifically refers to the former, and especially automatic cutting machine. In plasma cutting, according to the different types of plasma gas, air can be divided into

Plasma cutting, plasma cutting oxygen, argon, hydrogen plasma cutting. Now air plasma cutting machine cutting current at 120A less, 30 ~ 70A manual operation

Cutter majority. In Japan, air plasma cutting machine cutting machine with automatic number of units sold in the market has been quite [a.

Oxygen plasma cutting machine is mainly used for cutting thick shipyard, its cutting current to 350 ~ 500A based. Such cutters fewer users in Japan, was

Only manufacture more than 100 units [1]. Air plasma cutting machine cutting nitride nitrogen in the air side, directly submerged arc weld prone nitrogen Kong, and oxygen

Plasma cutting machine is to overcome this problem. Argon-hydrogen plasma cutting machine designed for cutting aluminum, stainless steel plate, the cutting current to 500 ~ 1000A based.

    2 plasma cutting technology development status

Development of plasma cutting technology for cutting stainless steel, aluminum and other materials. But the development so far, plasma cutting technology has been used for cutting carbon steel, mainly because other

Plasma cutting speed, easy to set the cutting conditions more suitable for automated, unmanned operation. The cutting of the cutting process often need to adjust the flame, cutting speed is slow, pre-

Thermal time limit cutting productivity, by contrast is not suitable for automated, unmanned operation.

Air or oxygen plasma cutting technology is the key cutting torch consumables life issues. As the air or oxygen oxidation, plasma cutting torch electrode

, The nozzle must be resistant to high temperature oxidizing atmosphere arc. So now hafnium electrode material using a high melting point, and in a special processing method embedded in copper. Nozzle mining

With a double flow structure, the advantage of improving the flow direction, speed, and plasma gas purity and cooling, to protect the nozzle, further compression of the arc. In addition to

A reduced electrode wear, arcing when cutting gas than pure oxygen with nitrogen, oxygen gas mixture, and a smaller flow rate, to be switched to oxygen from the arc. This

Outside the process of cutting nozzle in contact with the material being cut will damage the nozzle, which in the cutting torch height control efforts. Electrode and the short life of the nozzle now than in the past

Greatly improved, with a corresponding oxygen plasma cutting current maximum has been reached 500A. According to the literature [2] introduced, 400A oxygen plasma cutting, each electrode can work 3.5h, each

Nozzles can be operated 4.8h, than the literature [3] presented data has greatly improved.

    3 Comparative Analysis of thermal cutting France

    3.1 cutting efficiency

From cutting productivity perspective, not only depend on its maximum cutting thickness, and depends on its corresponding cutting speeds. Figure 1 summarizes the three kinds of hot-cutting method for cutting speed and cutting

Cutting thickness relationship, cutting material is carbon steel [1].

Contrast, plasma cutting and cutting CO2 laser cutting efficiency, 50A air plasma cutting efficiency is equivalent to 1.5kW laser cutting efficiency, 70A and 150A of the former

The latter is equivalent to 2kW and 6kW. 300A above with oxygen plasma cutting efficiency is very high-power laser cutting machine is not yet listed. Therefore, from the cutting efficiency perspective, cutting

50mm or less carbon steel, plasma cutting most efficient, cutting more than 50mm of carbon steel, maximum cutting efficiency of oxygen gas cutting.

    3.2 cutting quality

Table 1 compares the cutting, plasma cutting, laser cutting cutting surface roughness, cutting precision, cutting slit width, heat affected zone size [1], these factors are representative of

The cutting quality. As long as the correct choice of cutting method and cutting conditions, the cutting surface of the rounded edges and the lower edge of the sticky residue phenomenon can be overcome, so that two are not included in the table.On the cutting surface roughness, the general optimal plasma cutting. As long as special attention, not inferior to laser cutting, plasma cutting.

On the cutting accuracy and cutting slit width, the optimal laser cutting. If equipped with a cutting torch to ensure the accuracy and running gear motion characteristics, gas cutting, plasma cutting

Cutting accuracy is guaranteed.

Produced by cutting the width of the heat affected zone, deformation and cutting speed have a great relationship, cutting the cutting speed is slow, the heat-affected zone width, deformation is also large. General kerf

The narrower the cutting speed, the cutting material of the heat input is smaller, cutting the deformation is small. After testing and comparative analysis of the results is that the variation of laser cutting

Shaped minimum, plasma cutting deformation, followed by cutting machine the maximum deformation.

    3.3 Cost Cutting

Cutting equipment purchase costs depend on the production volume, production volume the greater the relative cost of the purchase of equipment smaller. However, cost cutting is proportional to the amount produced. Chart

2 compares the cutting, plasma cutting, laser cutting cutting costs, cutting costs, including replacement parts costs, gas, electricity, labor costs. Cutting costs is a single

Bit length cutting costs.
