Thermal lance also known as burning bar or thermic lance, made by hollow mild steel pipes filled with a number of iron wires, which is a powerful efficient cutting tool by high purity oxygen flow through the interior of the lance to create extraordinarily high temperature from 3,600 to 4,426�°C for cutting through just about anything. Thermal lance can be used whenever some ferrous and non-ferrous materials must be removed or cut into pieces, like sand casting riser cutting or ladle furnace tapping. When molten material is spilled, it can be allowed to solidify and then cleaned up with thermal lance. For coastal buildings, interior concrete sometimes breaks down to produce what is called concrete cancer, but thermal lance can be used to remove this degrading concrete so that replacement material can be packed in. These characteristics of the thermal lance make it a particularly efficient and cost-effective method of cutting steel and cast-iron materials too thick to be cut with a normal oxy-acetylene torch. In the case of thicker materials, during the operation, the lance tube will be consumed by the intense heat at the cut point and should be discarded once it becomes too short to be safely used.
