In the oxygen-converter shop of the Dneprovsky metallurgical plant (DMZ, Dnipro), a major overhaul of the converter No. 1 was carried out with the replacement of the neck and the tapered part.
The renovation took place since December 2020. The workers of the metallurgical equipment repair shop dismantled the old converter neck and installed a new one, which was cast in the molding shop.
During the repair, 3.5 rows of metal structures of the tapered part were replaced, which required the completion of about 120 meters of welding seams.
In March, specialists from the metallurgical furnace repair department joined the process. For 10 days they laid a new masonry. This time, Polish-made bricks were used for lining, the guarantee for these refractories is 2100 heats instead of the standard 1900.
As of today, converter # 1 has been put into operation after overhaul, converters # 2 and # 3 are in reserve.
