氧枪是现代顶吹转炉炼钢的关键设备,直接关系到钢的产量、质量和经济效益。历来以进口为主,为了使氧枪喷头国产化,我公司与首钢技术研究院和二炼钢合作,试研生产的热挤成型组合式转炉氧枪喷头在上机实验中保证了冶金效果良好,延长了使用寿命,节省了大量外汇,达到国内先进水平。根据氧枪喷头的机械结构特征,本文着重探讨了其加工工艺参数及加工保证体系。
Oxygen lance is the key equipment of modern top-blowing converter steelmaking, which is directly related to the output, quality and economic benefits of steel. In order to make the homemade oxygen lance nozzle, our company and the Shougang Institute of Technology and the second steel co-operation, trial and production of hot extrusion combined oxygen lance nozzle in the experiment on the machine to ensure good metallurgical effect , Extending the service life, saving a lot of foreign exchange, reaching the domestic advanced level. According to the mechanical structure of oxygen lance nozzle, this paper focuses on the processing parameters and processing assurance system.
