Double flow oxygen-burning lance nozzle is composed of inner pipe, middle pipe, oxygen outer welding pipe and oxygen inner welding pipe. There are main oxygen blowing holes and sub-blowing oxygen holes, and they are characterized in the main oxygen blowing holes which are Laval hole, the ratio of exit and throat area is between 1.148¡«1.919, dip angle ¦Á of blowing oxygen hole between 180¡«700. Mach number of sub-blowing oxygen hole is 1, and the amount of the hole between 1¡«8, the better living example is that Mach number of sub-oxygen hole is 1, and the amount of the hole between 1¡«8. The main difference between double flow oxygen-burning lance nozzle and general electric furnace oxygen lance nozzle is adding a layer of oxygen pipeline, that is from a layer of oxygen increased to two layer of oxygen pipelines, thus form total of four layers of pipe: the main oxygen line, sub-oxygen line, the water in line and out line. The oxygen flow and oxygen pressure of main and sub-oxygen line are separately controlled by furnace burden in electric furnace to optimize the effect of smelting. The main oxygen blowing hole is Laval hole, the sub-blowing oxygen hole is ordinary round hole, and the size and amount are decided according to smelting condition.
