oxygen lance nozzle / tip

Introduction of using environment Oxygen converter steelmaking is carried out within more than 10 minutes for the oxygen and gas supply, and in this short time, the task of slagging, decarbonization, desulfuration, dephosphorization, impurity, gas-disposing and heating must be completed. The reaction in the blowing is a complex process. The working nozzle have to bear high-heated load. The temperature of the reaction zone in the converter pool is above 2000 degree Celsius, and the melting point of copper is only 1083 degree Celsius. In order to increase durability and deformation resistance, and strengthen cooling water way. The effect is obvious, and the working situation is more ideal.

Usage introduction of assembling and forging nozzles'structure and properties Forging nozzle wall is homogeneous and smooth. Under the premise of guaranteeing mechanical strength, wall thickness is thinned. After the improvement, the heat can be transferred from the high-temperature outer surface to the wall by cooling water more rapidly. The guidance tapping cone is set up above and under the inlet. Then the flow can converge from round to center and in the center, the flip enhances cooling the nozzle end. After the enhancement, even though the nozzle end center surface sticks steel, 'eating in'phenomenon can happen, and the nozzle can continue to be used for a longer time. Because the pressure loss is mainly concentrated on the end, the high-pressure cooling water rises 30-40% more than the original and pressure control is 1.2Mpa to improve the cooling efficiency, then the entrance flow speed in the nozzle end can reach 9.6 to 11.2 m/s, and maximum temperature rising is 15 degree Celsius around. So better cooling effect further ensures the stability of jet and extends nozzles'lives. The life if general forged is 2 to 3 times than that of the casting nozzle.
