- Q519938 abstract "A thermal lance, thermic lance, oxygen lance, or burning bar is a tool that heats and melts steel in the presence of pressurized oxygen to create the very high temperatures required for cutting. It consists of a long steel tube packed with alloy steel rods, sometimes mixed with aluminium rods to increase the heat output. One end of the tube is placed in a holder and oxygen is fed through the tube.The far end of the tube is pre-heated and lit by an oxyacetylene torch. An intense stream of burning steel is produced at the workpiece end and can be used to cut rapidly through thick materials including steel and concrete. The tube is consumed, so every few minutes the operator shuts off the oxygen, discards the remaining stub of a lance tube and starts using a new one.Although often used as a heavy duty demolition tool, the thermic lance can also be used to remove seized axles of heavy machinery without damaging the bearings or axle housing. This technique is most often used on the pins and axles of large equipment such as cranes, ships, bridges and sluice-gates. The temperature at which a thermal lance operates varies depending on the environment. Kosanke gives the maximum temperature to be 4500 °C (4770 K), while Wang calculates it to be 2730 °C (3000 K).".
