 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 (≥3600℃)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. |
|
| It is used in steel-making for boring of concrete structure,remove burned sand,cutting stainless steel and nonferrous metal,cutting riser in ductile cast iron,cutting sheet or pipe pile and some other special steel,cutting pig iron mixed with slag,cutting blast furnace shell,cutting&boring furnace bottom refractory brick. |
