《Baosteel Technical Research》2010,(Z1):109
Due to fast development of Chinese steel industry,continuous adjustment of product,improvement of quality,research of value-added product,RH technology is significantly developed.More and more steel plants are covered with RH facilities.RH ratio is growing rapidly as well.Over past decade,through assimilating advanced foreign technologies and further refining them,Chinese large scale steel plants master the technology of RH production,operation,maintenance and make it more widespread.RH functions are well applied and improved.RH is more widely effectively put into use.Through independent innovation,RH core devices and technology,such as RH vacuum pump,oxygen top lance,vacuum vessel preheating lance,ladle lifting device etc.have realized localization.The development of equipment design,software design,equipment manufacturing technology,equipment mounting,test technology and EPC management makes equipment configuration more flexible,equipment more functional and stable,easier to operate and maintain.It also guarantees highly effective and low energy consumption production and quality of steel,reaches international advanced level,lowers the cost of RH construction and operation,makes after-sake service more convenient. How to continuously optimize and develop RH process,equipment and control technology,in order to meet the needs of product with more reasonable and economic process,exploit potentialities,build more effective,lower cost,lower energy consumption,protecting environment RH facilities will be the key point of future RH technology development in China. 相似文献

With the strong demand for the development of automobile sheets, tin plates, household appliances, silicon steel, pipeline steel and other products as well as for the quality improvement of steel products, remarkable progress has been made in RH refining technology and equipment design since Baosteel began production more than 20 years ago. The vacuum degassing ratio of Baosteel has jumped from 35% in the initial stage when Baosteel began production, to the current ratio of approximately 60%, and will soon reach 75% in the near future. The independent innovations in RH refming technology in Baosteel, such as RH equipment optimization, vacuum decarburization, inclusion control, deoxidation, desulfurization, rhythm adjustment between primary steelmaking and continuous casting, the high efficiency of the RH refining process, and other aspects of RH technology, have all effectively met the requirements of developing new steel products, quality improvement and logistical control. Complete sets of RH equipment and refining technology have been successfully exported to the domestic steel plants. In the future, Baosteel will make further efforts to improve efficiency, stabilize production and quality, and realize special line production, so that the RH degasser will play a greater role in Baosteel. 相似文献
