Lance pipe is used for blowing in steelmaking, it is made of steel pipe with inside & outside surface calorized & ceramic coated

EAF & converter blowing

Anssen 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;
