Thermal lance
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 very high temperatures for cutting. It consists of a long steel tube packed with alloy steel rods, sometimes mixed with aluminum 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 working end and  can be used to cut rapidly through thick materials, including steel and concrete. The tube is consumed by the process within a few minutes. Often used as a heavy duty demolition tool, the thermic lance is also used to remove seized axles of heavy machinery without damaging the bearings or axle housing. This technique is 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 , while Wang calculates it to be . In  Popular Culture. The thermal lance is seen in at least three movies, in which the main characters are robbing bank vaults: "Thief", starring James Caan and Tuesday Weld; "The Real McCoy", starring Kim Basinger and Terence Stamp; and "The Bank Job", with Jason Statham. It is also seen in the "Burn Notice" season 4 episode "Hot Property", and the "Person of Interest" season 3 episode "Mors Praematura".
