Cutting or burning of steel,requires an oxygen purity content of 99%.When steel is brought to its kindling temperature,the combustion process will initiate when oxygen purity of 99% is added directly to the steel.6.If when cutting or burning steel using a oxy fuel cutting torch,the cut isElectroplated CBN Sharpening Wheel for WoodturnersDiameter 6 inch,8 inch and 10 inch Thickness :1 inch,1.5 inch and 2 inch Arbor hole :1/2 inch,5/8 inch,1-1/4 inch Radius edge 1/4 inch Grain Size 80#,180#,220#,350#,600#,800#,1200# etc.Applicable grinder sharpening woodturning tools (high speed steel HSS) on bench grinder Advantages * Fast and cool cutting action without coolant * No need dressing or turning
Flame cutting (also known as oxy fuel cutting),it is to use the heat burned from oxy fuel gas,to cut steel materials or the hard metals to the panels or profiles required.It can cut steel thickness from 1 mm to 1200 mm.And in most cases it used to cut steel plate thickness more than 20 mm,since oxy fuel cutting usually brings big tolerance.Gas selection guide - plasma cutting aluminum,mild Argon hydrogen is the gas of choice for thick stainless and aluminum cutting ( gas cutting steelsgt; 1/2) The mixture typically used is 35% hydrogen 65% argon (H-35).Argon hydrogen is the hottest burning plasma gas and provides the maximum cutting capability.(Argon hydrogen is used in water injection torches up to 1000 amps for cutting up to 6 stainless).
The process consists of preheating the metal to be cut to its ignition (oxidation) temperature,i.e.,above 870 gas cutting steels#176;C in case of steel.The preheating is done by oxy-acetylene gas flame,which is supplied from surrounding openings of the cutting torch.When this temperature is attained,a jet of high pressure oxygen from a central opening of the cutting torch is directed on the red hot metal.Improved plasma cutting of stainless steelGas Type An oxygen plasma gas with an air shield can deliver excellent cut quality across the full range of thicknesses in mild and carbon steel.However stainless steel cutting success requires different gases and consumables for different thickness ranges and grades.
