Oxy-fuel cutting; the basics explained HGG 3D Profiling

This slag has a lower melting point than steel, so the oxygen stream can blow the liquid slag out of the cavity without affecting the non-oxidised solid steel. This exothermic reaction is a continuous process and creates a cut as the torch moves. To keep the exothermic reaction working, the cutting torch keeps the steel heated during cutting.

Kinetics of oxyfuel gas cutting of steels

A stream of oxygen then trained on the metal combines with the metal which then flows out as an oxide slag to create the kerf (Union Carbide Corp, 1975; DeGarmo et al., 1999; AWS, 1997). The cut quality depends on the torch tip size, type, and distance from the metal (AWS, 1997), the oxygen and preheat gas flow rates, and the cutting speed.

Flame Cutting (Oxy Fuel Cutting) - A Method to Cut

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.
