oxygen lance pipe

Lance pipe is used for blowing in steelmaking, it is made of steel pipe with inside & outside surface calorized & ceramic coated,due to the user's requirement for low consumption, high purity during smelting process in EAF/BOF, Anssen succeeds in developing a high quality coating at competitive cost, it has a great advantage in anti-oxidation, anti- sulphurization, thermal resistant, anti-erosion, easy operation, its main use

·Blowing oxygen or other gas into EAF

·Injection of powder additive to adjust the steel composition

·Clean slag from converter

·Special purpose which requires high refractoriness, anti-oxidation, anti-sulphurization, anti-erosion
