Supply High Quality Copper Mould Tube for Continuous Casting MachineOxygen Lance Pipe,are small diameter pipes used with oxygen is an invaluable tool for the primary metalsindustry. It is used daily in almost all ferrous and non-ferrous primary production facilities.This small diameter pipe serves below purposes for these industries:
Carbon and other chemical constituents impart certain attributes or properties to a metal and these elementsmust therefore be carefully measured and controlled during the smelting process. Employed in blast furnacesbasic oxygen furnaces as well as induction and electric arc furnaces, oxygen lance pipe is used for decarburizc.e. a process of pumping an oxygen rich mixture at high pressure through oxygen lance pipe into the melt. Theoxidizing effect burns off the excess carbon in the molten metal thus reducing the percentage of carbon to anacceptable level.
When the desired steel composition and temperature has been reached, the furnace tap hole is opened through acombination of drilling and tapping using oxygen lances. Lances are coupled to a high pressure oxygen supplythe end of the lance is ignited and through careful and skillful manipulation, the tap hole clay which can be up to800mm thick is effectively burnt away, facilitating the pouring of the molten metal for further processing.
Ladle well blocks require cleaning once the casting process has been completed. Ladles are tipped to remove theslag. Oxygen lances are employed to clean both the upper and lower nozzles and if necessary, the bottom of theladle is also cleaned with a lance pipe if it contains impacted debris.
Iundishes are receptacles used to temporarily store a batch (melt) of molten metal while it is moved through theproduction process. Unclogging nozzles with oxygen lance pipe is a more cost effective option than replacingentire nozzle systems.
Oxygen lances are used effectively to cut and clean skulls which are layers of slag and process metals that havesolidified or frozen against the refractory material forming a layer of insulation which reduces heat losses andprotects the furnace lining from erosion, chemical attacks and thermal shock.
Oxygen lances are used to cut up solidifed molten metal spillages into smaller pieces facilitating handling andthus aiding the re-smelting or disposal of the sometimes valuable spilt material.
