Oxygen lance is used to decarburize, dephosphorize or extract alum This kind of product is used for converter and eaf Raw material: steel pipe The main functions of oxygen lance body are: to supply oxygen and cooling water to the nozzle, whose structure should meet the production needs of converting steel-making, and is favorable to the replacement and maintenance of nozzles, to compensate action force to oxygen lance nozzle caused by outer pipe in case of thermal expansion. Appropriate lance barrel length goes upward oxygen&water supply pipe and downward molten bath surface, oxygen supply meets the need of converter nominal tonnage, and water supply guarantees cooling performance of that the oxygen lance furniture. In this case, oxygen lance designed and manufactured is reasonable, safe and stable, energy-saving and low consumption, which is effective practical converting steel-making equipment.
