14.6 Cutting Steel with the Oxyfuel Gas Cutting Torch

A student is practicing oxyfuel gas cutting on thick 1 1/2 (38mm) mild steel. Normally, the tip is perpendicular to the surface being cut. The end of the inner cone of the preheating flame should be held just above the metal. If the cutting tip has 4, 6, or more preheating orifices, one orifice should precede (lead) the cutting orifice.

The oxy-fuel process utilizes a flame to generate heat for cutting, welding and brazing. Care must be taken to avoid the contact of the flame with any combustible substances. A firebrick top workbench is recommended for cutting on. Ensure that you have adequate Choosing Between Plasma Cutting and Oxy-fuel SystemsMar 15, 2016 · With oxy-fuel cutting, an oxygen/fuel gas flame preheats the steel to its ignition temperature. A high-powered oxygen jet is then directed at the metal, creating a chemical reaction between the oxygen and the metal to form iron oxide, also known as slag. The high-powered oxygen jet removes the slag from the kerf.

Choosing a gas for oxyfuel cutting - The FABRICATOR

Oxyfuel cutting is a process used to sever steel via a chemical reaction of oxygen with the base metal at elevated temperature. Once oxygen is mixed with a fuel gas, the temperature rapidly increases to a point high enough to melt and wash away the steel. The oxyfuel cutting process is nothing more than rapid oxidationalso known as burning. Choosing a gas for oxyfuel cutting - The FABRICATORThe oxyfuel cutting process is nothing more than rapid oxidationalso known as burning. Of course, cost is always a concern for fabricators, and the cost of fuel gaswhether acetylene, propylene, or propanetypically represents 20 to 25 percent of the total cutting cost.

Cutting Processes - Application of Oxyfuel Cutting - TWI

18% cutting labour; 1-2% gas; Consideration should, therefore, be given to the choice of fuel gas type and nozzle design to speed up the initiation of the cutting operation. Labour costs can be reduced by decreasing the pierce time and/or increasing the cutting speed. Typical flame temperatures and fuel gas to oxygen ratios are shown in Fig. 1. Fuel Gases Used for Oxyfuel Cutting FractoryFirst, a mixture of cutting gas and oxygen is directed onto the work piece through a cutting torch to preheat it. The objective is to achieve the ignition temperature, which is around 700900° C for carbon steel. The temperature has to be well below the melting point, which is why flame cutting is unusable for some metals like aluminium.

Preheat flame temperatures will range from 4,440° to 6,000° F depending upon the fuel gas used and the adjusted ratio of oxygen to fuel gas.

How to Choose Between Oxyfuel and Plasma Cutting

Jul 15, 2019 · In Oxyfuel cutting a fuel natural gas heats the metal to its kindling temperature, where a high-pressure stream of pure oxygen rapidly oxidizes and blow away the metals. This process works well with carbon steel because iron oxide melts at a lower temperature than steel. The Oxyfuel does not work with Aluminium because it melts at a very high Mid-South Metals Oxy-Fuel CuttingOxy-fuel cutting is a chemical reaction between pure oxygen and steel to form iron oxide.
