Eximious design of heads throat & flared tube is optimized by Experts from MEPC 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.
