1. steel coil to steel plate

2.Flame cutting

Flamecutting or “burning” of carbon steel plate is an effective and efficient way to cut carbon and alloy steel plate to size and shape. 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.

3.Laser cutting provides the tightest tolerances and most precise cut surface. It produces the smallest heat-affected zone in the metal compared to all other thermal cutting processes.
