Czech metallurgical specials are heading to Slovakia

U. S. Steel Košice is an integrated steel company with more than 50 years of tradition and production capacity of 4.5 million tons of steel per year. The company, one of the largest in Slovakia, employs almost 11,000 people.

The blast furnaces ensure the transformation of iron ore raw materials into liquid metal within the metallurgical primary production plants. The three blast furnaces built in the late 1960s at U.S. Steel Košice have undergone significant modernization and are now among the most advanced in Europe in terms of technical equipment and production capacity.

This year, a major project called "Rebuilding of Heater No. 14 at Blast Furnace No. 1" is being implemented as part of the investment project. Construction began in early April and the work is scheduled to be commissioned by the end of December 2021.

For the reconstruction of OV14, Basic and Detail engineering by Danieli Corus is used. The general contractor of the construction is Termostav - Mráz, a company operating on domestic and foreign markets in the field of refractory linings, industrial assemblies, and special insulation.
