Flame Cutting, Flame Cutting Machinery

Bebon is a supplier of carbon steel plate in China. We also offer steel plate cutting services. Flame cutting is often used in steel plate cutting. Flame cutting or “burning” of carbon steel plate is an effective and efficient way to cut carbon and alloy steel plate to size and shape. Flame cutting is a method of cutting ferrous metals in which the metal is heated by a torch to about 800°C and is oxidized by a stream of oxygen from the torch.

Flame Cutting Process:
Burning begins by heating a spot on the edge or surface of a plate with an oxy-fuel flame, then injecting a high pressure stream of pure oxygen once the spot is red hot. Both the preheat flame and the cutting oxygen are delivered through a specially designed nozzle or tip. In the presence of the cutting oxygen stream, the red hot steel literally burns, combining with the oxygen to form iron oxides. It is this burning that cuts the plate as the stream of cutting oxygen advances along the path of the cut. The burning gives off an intense heat – greater than 2800º F – which melts steel bordering the cut path, turning it into slag that is ejected at the bottom of the cut along with the iron oxide by-products of the burning.
Flame Cutting Features:
Proper flamecutting results in a smooth burn and a cut edge that is square within 1-1/2 degrees to the surface of the plate. A number of variables determine that outcome. These include certain specifics like: size and design of the cutting tip; pressure and volume of the gasses; speed of the cut. All of these vary by thickness and grade. However, it is the skill and experience of the burner that will choose the right combination of these to overcome the more subjective conditions. Temperature of the plate, internal soundness, chemistry, surface scale – all of these can have an affect.
Our qualified workers can produce flame cutting steel products by flame cutting machinery. If you need any steel plate cutting, please contact us.
