Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the U.S.) and oxy-fuel cutting are processes that use fuel gases (or liquid fuels such as gasoline) and oxygen to weld or cut metals. French engineers Edmond Fouché and Charles Picard became the first to develop oxygen-acetylene welding in 1903.
Oxy-Fuel gas cutting is functional for use with low carbon and low alloy steels, with a carbon content generally restricted to 1/10 to 3/10 of 1%. The various alloy elements found in steel affect the ability of the oxygen to cut the metal. Elements such as manganese, silicon, phosphorus, and sulfur have very little effect in normally found levels.
Some small oxy-fuel systems weigh about 35 pounds, so with oxy-fuel tanks and a torch, it is possible to cut steel almost anywhere. Oxy-fuel torches are normally used for cutting only ferrous, or iron-containing, metals, and for the most part are not used for cutting cast iron, aluminum or stainless steel.

Oxy Fuel welding (OFW) is a group of welding processes which join metals by heating them with a fuel gas flame or flares with or without the application of pressure and with or without the use of filler metal. OFW, Oxy Fuel welding includes any welding operation that makes use of a fuel gas combined with oxygen as a heating medium.

May 06, 2019· Where an unplanned shutdown from breakdown has occurred, getting the Blast Furnace back to operating conditions using traditional methods may be extremely time consuming and nearly impossible Firebridge Inc. has successfully designed, constructed and operated portable Oxy-Fuel Lance systems on several Blast Furnace start-ups/recoveries.
Close the fuels gas and oxygen cylinder valves, back out the fuel gas and oxygen regulator adjusting screws until they are loose, open the fuel gas alve to allow gas to escape, than close it, open theoxygen valve to allow gas to escape, and then close it, making sure all pressure is released and all reulaor gauges read zero, and coil the hose and secure the torch to prevent damage
had been converted to oxy-fuel firing 0 Many glass companies were making additional commitments to the technology, which by the end of1997 had resulted the conversion of about 25% ofglass furnaces to oxy-fuelfrring~ Withthe critical mass ofoperating experience andmany newconversions coming on-line,itwas anopportune time to transferknowledge on
Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.
Oxygen-enhanced combustion technologies can help improve furnace performance by displacing combustion air with oxygen. Even a small increase in oxygen concentration can have a dramatic impact on furnace operations, especially when using fuels with low heating values, and/or improving operations or regaining control of furnaces with failing heat recovery devices.
ADVERTISEMENTS: Subject-Matter of Oxy-Acetylene Cutting Process: In modern steel-age the steel-makers cut Iron and Steel by oxy-acetylene, oxy-hydrogen, oxy- propane, oxy-natural gas cutting blowpipes easily, speedily, and cleanly. Cutting of metals by means of flame has many advantages over other methods, specially when the metal is of irregular shape.
Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements.
Since the advent of arc welding, very little industrial work is still performed with the oxy/fuel process. Artisans still use the method some for creating artwork. When the cutting torch head is attached to the oxy/acetylene handle, it becomes a powerful instrument for cutting metals.
Introduction For the ore based iron-making process, hot stoves are very important auxilary equipment to the blast furnace (BF), providing hot blast to the process. The blast provides thermal energy and reducing gas to the BF process through combustion of coke and injected fuel at the tuyere level.
