--Original Know-how Developed by SUN-GLARE Oxygen lance head shaped by forging, as new product in 2005, is Original Know-how Developed by SUN-GLARE. **ADVANTAGE Eximious design The design of heads throat & flared tube is optimized by Experts from SUN-GLARE according to type and capacity of converter as will as amount of blowing oxygen and cooling water. High quality material High pure E-Cu or SF-Cu is used. Advanced process method Oxygen lance head is shaped by forging unitarily. Stabilization of oxygen jet-flow Because of the good anti-creep speciality of the material forged. Long working life Through forging, the head gets high density, which is helpful to increase heat conductivity, and increase cooling effect. ** MATERIAL Material Chemical CompositionMechanical PropertiesElectricConductivity(%IACS)Cu(%)Others(%)TensileStrengthσb(N/mm2)YieldStrengthσ0.2(N/mm2)Elongationδ(%)Hardness(HB)E-Cu99.9020040404598SF-Cu99.85P0,012 0.050305235188585
