At 2:00 p.m. on August 8, the No.4 converter of Panzhihua Iron and Steel Co., Ltd. completed the 71 day dust removal technical transformation construction and put into production, two days ahead of the planned construction period, marking that the company's hot metal vanadium extraction production has stepped to a new clean and environmental protection stage.
In order to meet the requirements of national environmental protection, realize clean and green production of vanadium extraction from hot metal and rectify the hidden dangers of equipment, the company carried out dust removal transformation and overhaul of two vanadium extraction converters in the second half of 2019. Among them, converter 5 was put into operation on December 22 last year. The No. 4 converter put into operation was shut down on December 28 last year, with an estimated construction period of 73 days. It focuses on upgrading the primary dust removal, secondary dust removal and other environmental protection facilities and related supporting systems, and simultaneously implements the converter overhaul, emission tower transformation and other projects.
In addition to overcoming the difficulties of long construction period, many projects and difficult safety management and control, this construction also faces challenges in cross year construction, epidemic prevention and control, logistics support, vanadium slag production and other aspects. In order to ensure the construction safety, quality and progress control, the vanadium extraction steel plant adheres to both technical transformation and Production assurance. Led by the project department and actively participated by all relevant units, the construction network has been optimized for many times, the construction safety has been focused on, and the illegal assessment has been strictly implemented to ensure the safety and stability of the construction process. At the same time, the plant takes unconventional measures such as steel-making converter extracting vanadium in turn, optimizing logistics organization, and on-site management personnel on duty to ensure the smooth production. Since the outbreak of novel coronavirus pneumonia, some management and construction personnel can not return to their posts in time. The project department shall adjust the engineering network in time, give priority to the major nodes such as converter overhaul and dust removal transformation; each unit shall implement the epidemic prevention and control measures for construction personnel, so as to ensure that there is no shutdown during the epidemic period and the construction progress is not broken.
After the completion of the dust removal transformation, the dedusting effect of the vanadium extraction process of the plant is better, the production is cleaner and environmental protection, and the equipment operation is more stable. Next, the plant will do a good job in the construction of No. 4 and No. 5 converter gas recovery systems, so that Panzhihua Steel Vanadium vanadium slag production to a new level of green and low carbon.
