Burning Bar General Information GENERIC TERMS: EXOTHERMIC TORCH- THERMIC TORCH - MAG ROD - MAG BAR - LANCE BAR - LANCE ROD - THERMIC LANCE The Oxylance Burning Bar and Sure Cut rods are self consuming cutting tools used in a wide variety of industries for cutting most ferrous and nonferrous metals, refractory and concrete. Benefits over conventional cutting methods are faster cutting speeds and the ability to cut thick sections as well as rusty or corroded materials. WHAT IS THE DIFFERENCE BETWEEN OXY-FUEL AND EXOTHERMIC CUTTING? The Oxy-Fuel cutting torch uses a preheat flame to elevate the temperature of the material to be cut to 1500 to 1900 degrees F. When the steel becomes cherry red a high pressure jet of oxygen is directed at the pre-heated metal. The result is the metal is rapidly oxidized or it burns. This process works on material that will oxidize. If it will not rust it can not be readily cut with an oxy-fuel system. The Exothermic process also utilizes oxidation. However; the exothermic process uses alloys in the material in the burning bar as the fuel and produces temperatures of 7200 degrees F. A Burning Bar consists of an outer steel tube filled with special alloy wire. The exothermic reaction (Oxidation) occurs when the tip of the rod is heated to its kindling temperature (2800 f) and pure oxygen is introduced through the bar. The chemical reaction will continue until the bar is consumed or the oxygen flow is turned off. The only gas required for this cutting operation is pure oxygen. Cutting steel with an exothermic torch
