Why plasma cutting is more efficient than flame cutting?
First, plasma cutting Plasma cutting is the use of high-temperature plasma arc with high energy density to focus on the incision heating, rapid melting cutting technology, plasma cutting is considered to be one of the most ideal cutting method in the thin plate, with its high cutting efficiency, good quality and much User's welcome. Especially since the 1990s , due to the continuous improvement of plasma technology, the service life of its consumables such as electrodes, nozzles, and swirl rings has been continuously improved, which has led to a drastic reduction in the cost of plasma consumables and broadened the prospects for the application of plasma cutting. . The following is a comparison of plasma cutting machines and conventional oxyacetylene cutting: 1. Comparison of cutting costs The main cost of plasma cutting is the cost of its consumable electrode, nozzle, and swirl ring. The cost of oxyacetylene cutting is mainly the cost of oxygen and acetylene. The two cutting costs are now calculated as follows ; CNC oxyacetylene cutting, cutting thickness of 18mm per meter of steel consumption costs: gas M3/ bottle Yuan / bottle Yuan /M3 Note oxygen 4 19 4.75  Acetylene 5 70 14   Thickness (mm) Cutting speed (mm/min) Oxygen flow (m3/h) Acetylene flow (m3/h)  18 520 3.65 0.73   Cutting One meter steel plate oxygen consumption costs: 3.65 ÷ 60 ÷ 0.52 = 0.12 (m3) 0.12 yuan x 4.75 = 0.57 yuan Cutting One meter steel plate acetylene consumption costs: 0.73 ÷ 60 ÷ 0.52 = 0.024 (m3) 14 yuan x 0.024 = 0.34 yuan Cutting One meter steel plate total cost: 0.57 yuan + 0.34 yuan = 0.91 yuan CNC plasma cutting, consumption cost per meter of cutting steel plate thickness 18mm : The following plasma uses the Russian MT3500 plasma multifunction cutting machine as an example: Russia MT3500 plasma multifunction cutting machine project Continuous cutting service life unit price Calculated using life Yuan / hour Note electrode 4-6 hours 50 yuan 4 hours 12.50  nozzle 4-6 hours 128 yuan 4 hours 32  Swirl ring 15-25 hours 181 yuan 10 hours 18.10   Electric current power effectiveness Thickness Electricity price Cutting speed 200A 30 KW 100% 18mm 0.80 yuan / degree 1500 mm /min Cutting steel plate per hour electricity fee: 30KW x 100% x 0.8 yuan = 24 yuan Consumables cost per hour: (12.5 + 32-membered membered +18.10 membered) = 62.6 yuan Cutting plate cost per minute: (12 yuan + 62.6 yuan ) ÷ 60 = 1.24 yuan Cutting One meter steel plate total cost: 1.24 yuan ÷ 1.5 = 0.826 yuan Through the above theoretical calculations, it can be seen that the cost per meter of flame cutting is higher than that of plasma cutting. Comparison of production efficiency Plasma cutting 18mm steel plate speed is 1500mm / min , the flame is 500mm / min , plasma is 3 times the flame , production efficiency is quite high. Comparison of cutting quality Comparison of cutting quality shows the superiority of plasma cutting. Plasma-cut workpiece without burrs and slag, smooth surface without collapse, cutting surface smoothness up to 3 , cutting accuracy per meter long tolerance of not more than 0.5mm , workpiece deformation is small, can replace or eliminate the machining process, through actual proof Plasma-cut parts are not machined to fully meet welding assembly quality requirements. Comparison of economic benefits The use of plasma-cutting workpieces can eliminate the need for machining, that is, machine-processing equipment can be saved, and machining costs can be saved by several hundred thousand yuan each year. Not only that, due to the high efficiency of plasma cutting, a plasma can replace 2 - 3 Taiwan flame cutting machine, and greatly reduce the area of ​​production operations, improve the effective use of plant efficiency, its comprehensive benefits are very substantial. in conclusion The cost of plasma cutting machines is comparable to that of flames. However, due to its high efficiency, high quality, and considerable economic benefits, although the previous plasma cutting machine has a large investment, it is still the best choice. It is recommended that factory leaders create conditions to purchase CNC plasma cutting. machine. The factory can choose a flame and a plasma torch on the configuration so that it can be prepared for the future increase of production.

The Channel girder is a cost-effective solution for short to medium span structures. The top deck can be manufactured with a variety of traction profiles, eliminating the need for field applied wearing surfaces. Standard Channel Beam sizes are listed below in 20", 24", 28", 32" and 36" depths, but custom sizes and adaptations such as extended flanges or 2nd cast curbs are easily attainable. While the Channel Beam section was originally developed for bridges, it is also popular for marine pier, building and garage applications.
