contactFlame cutting is a standard process primarily used for cutting mild steel. In flame cutting, oxygen is used as the cutting gas. The oxygen is blown into the kerf at pressures of up to 6 bar. There, the heated metal reacts with the oxygen: it begins to burn and oxidizes. The chemical reaction releases large amounts of energy - up to five times ...
contactWhat is flame cutting? Flame cutting is oxygen cutting in which the appropriate part of the material to be cut is raised to ignition temperature by an oxy-fuel gas flame (definition from BS 499:Part 1:1991 Section 7 No.72 002). Also known as oxy-fuel cutting, the process is used for separating and shaping steel components.
contactFlame cutting uses oxygen and a fuel source to create a flame to melt material. A Process Known by Many Names. The process often called Flame Cutting is known by various terms, such as Oxy Acetylene Cutting, Oxy Fuel Gas Cutting, Oxygen Burning, Steel Burning, and other terms too many to mention. The process is now about 111-112 years old as it ...
contactThe flame cut can be done with a flame cutting gauge, thus a 90° cut to the rail is possible. If rails with 880 N/mm² minimum tensile strength are installed then the rails should be warmed before the start of flame cutting. The rail should be warmed over a length of 1 m around the place to be cut (to about 50°C).
