thermal cutting technology and applicable industry

The so-called thermal cutting, from the way it mainly includes flame cutting, plasma cutting and laser cutting three kinds, according to the market price cutting requirements and different, all three cutting

Methods currently occupy a certain market, and its technical and economic comparison the following analysis:
As pressure flame cutting, cutting nozzle height, and the warm-up time and other factors, the overall cut material reusable fitting deformation scale is large, can not meet the needs of high-precision cutting

, And the cutting speed is low, and because to be preheated before cutting, spending time, it is difficult to adapt to the needs of unmanned operation. Plasma cutting with cutting speed, Fan

Wai width and other characteristics, is suitable for cutting low thickness of sheet metal and nonmetal materials, maximum cutting speed of up to 10m/min, flame cutting is 10 times. In the underwater cutting

Can eliminate noise generated when cutting, dust, harmful gases and arc, environmental protection requirements. With the current high-power plasma cutting technology matures, cutting thickness

Up to 130mm, using water jet cutting technology has made high-power plasma cutting quality precision laser cutting close to the lower limit (± 0.2mm). As the laser cutting machine price

Expensive and currently only suitable for sheet metal cutting (usually perforated plate a long time), and fine plasma cutting machine laser cutting accuracy up to the lower limit, the cutting surface bsp fittings quality

Amount of similar, but far less than the cost cutting, laser cutting, is about a 1/3, the maximum cutting thickness up to 12mm, so with precision plasma cutting machine to replace expensive

Laser cutting machine, in favor of the most economical way to a larger amount, the sheet speed fine cutting implement. In addition, CNC plasma cutting and automatic nesting programming software

Pieces of material utilization can be split flanges improved with 5% to 10%, the annual cut 20 million tons total, the annual savings of 100 to 2 million tons of steel, worth billions of dollars. Therefore, in the industrial hair

Of countries have emerged to replace CNC plasma cutting machine flame cutting machines and laser cutting machines trends.
