In late 2020, Primetals Technologies received the final acceptance certificate (FAC) for a newly installed advanced gas cleaning system based on wet electrostatic precipitator (WESP) technology. This first project was successfully implemented at Changzhou Eastran Special Steel Co. Ltd. in China’s Jiangsu province. Based on very strict requirements of the local city government an emission limit of 10 mg/Nm³ was requested for the steelmaking plant with two 80t basic oxygen furnaces (BOF). Primetals Technologies developed a suitable solution for the customer in terms of performance and minimal space requirement.

In July 2020, EVRAZ NTMK, a Russian steel producer, awarded Primetals Technologies an order to upgrade process optimization of the four BOF converters in its Nizhnij Tagil plant in Russia. The intelligent software from Primetals Technologies will replace the existing Level 2. Currently, the converter operators frequently have to intervene manually. The new process optimization solution offers dynamic, physical models with greater computational accuracy, and will allow improved converter operation, providing optimal converter production control across all shifts. The standardized mode of operation is expected to be accompanied by a reduction in the quantities of additives used.

Primetals Technologies has received the final acceptance certificate (FAC) for two semi-automatic horizontal temperature and sample-taking manipulator systems installed at the two BOF converters at the steel plant of Dillinger Hütte (AG der Dillinger Hüttenwerke) in Germany. The aims of this modernization project were to improve operational safety by automating the processes and thus reducing physical presence of operators in potentially hazardous environment as well as to improve availability – up to 98% in three-shift operation and reproducibility of temperature measurements and sample taking. Previously, temperature measurement and sample taking at the two 190-ton-converters were conducted manually.

In August 2020, Primetals Technologies received an order from HBIS Group Handan Iron and Steel to upgrade an existing BOF converter in the steel plant in Handan, China, to a KOBM (“Kombinierter Oxygen Blown Bottom Maxhütte”) converter including the complete automation system. Compared to a BOF converter, the combined blowing from top and bottom in a KOBM converter results in a better bath mixing, and metallurgical reactions are closer to the equilibrium.

In May, the Mechel Group issues the final acceptance certificate (FAC) for a LD (BOF) converter modernized by Primetals Technologies in the steel works of the Chelyabinsk Metallurgical Plant (ChMK) in Russia. The project aims were to replace worn-out equipment, to further increase capacity by raising the tapping weight to 160t and to optimize tap-to-tap times by cutting the blowing time. At the same time, Mechel installed a new cooling stack and the associated offgas cleaning plant to reduce converter emissions.
