Chinese company extends lance tube life to 1 year
Yong Steel Group, an iron and steel producer in China, has managed to extend the service life of its pulverised coal injection (PCI) lance tubes – one of the most important blast furnace components – from one month to one year by replacing standard grade tubing with Sandvik 253 MA.
Sandvik 253 MA is an austenitic chromium-nickel steel that is designed for excellent high temperature oxidation resistance and carburisation corrosion resistance and good high temperature strength.
