Anssen Calorized ceramic oxygen lance pipe
Due to the requirement of steel making for low consumption,high purity during smelting process in EAF/BOF,Anssen metallurgy succeeds in developing a high quality coating(calorized with ceramic) at competitive price for lance pipes, it has a great advantage in anti-oxidation, anti- sulphurization, thermal resistant, and anti-erosion.
Main application :
Blowing / conveyoring oxygen and other gas for EAF
Injecting / blowing powder additive for adjusting/refining steel composition;
Clearing slag out of Oxygen converter
