Flame cutting is the fastest and the most efficient cutting technology for the thick steel plates. Cost-efficiency can be achieved in large quantities with multi-torch drive. In addition, the flame cut kerf is straight. The part dimensions are the same on the top and at the bottom of the plate. Our flame cut parts can be used in steel structures requiring CE-marking.
Most of the steel plate qualities – like structural, wear-resistant and pressure vessel steels – are suitable for flame cutting. Unalloyed and low-alloyed steels with carbon content less than 0,3 % can be flame cut without any special arrangements. Stainless steels cannot be flame cut.
Flame cutting is the most common thermal cutting technology. In the cutting the starting point is heated by the gas to the ignition temperature. The cutting oxygen is added and the high-pressure jet burns the metal and blows the molten material away from the kerf. Flame cutting is rather simple and low-budget technology for over 5 mm thick steel plates.
There are some requirements for the material to be flame cut:
- heated metal burns in clean oxygen
- the ignition temperature of the metal is lower than the melting temperature
- burning reaction creates enough oxygen
- the thermal conductivity of the metal is low enough
The greatest advantage of the flame cutting compared to mechanical or other thermal cutting technologies is the capability to cut very thick steel plates. This is made possible by the process itself because the cutting energy comes as a result of oxidation of the metal which is an exothermic reaction.
