Zaporizhstal is improving the quality of its metal products due to the improvement of the production process technology.
According to the enterprise, in particular, new conditions have been established in the steelmaking shop for the steelmaking technology. In June, metallurgists began smelting metal on their own carbon, which makes it possible to stabilize metal in molds, as well as reduce the risks of producing metal with increased oxidation in molds. In turn, this will also save on deoxidizers fed into the ladle.
“We found out that this is what has a direct impact on whether we get certain types of defects when rolling metal. We conducted several test melts of steel and decided to apply this technology to some steel grades,” Andriy Riaznov, head of the technical control department, explained.
The use of this steelmaking technology has led to a significant reduction in the formation of defects. This decision is expected to lead to a reduction in the number of nonconforming products by approximately 15-30%.
“So far, we have just started working on this technology, but we are already seeing a positive result. According to preliminary data, the number of nonconforming products was reduced by 15% in June,” Riaznov said.
Zaporizhstal is one of the largest industrial enterprises in Ukraine, the products of which are in great demand among consumers in the internal market and in many countries of the world. The plant specializes in high quality hot-rolled steel, hot-rolled sheet, cold-rolled sheet, cold-rolled coil of carbon and low-alloy steels, as well as steel tape, black sheet, and a bent profile.
