[Ferro-alloys.com] Russian steel maker Mechel’s Chelyabinsk Metallurgical Plant has smelted the jubilee 300 millionth ton of steel since the plant was opened in 1943. The jubilee ton was smelted at converter # 1 of the oxygen-converter shop. The first steel smelting at the Chelyabinsk Metallurgical Plant took place 78 years ago. The first steel was tool steel and was used to make tools, from hammers to shovels. After that, Chelyabinsk metallurgists mastered steel grades for the defense industry. The metal was used to create engines for tanks and combat aircraft. During the war years, over 150 thousand tons of steel were produced.

This steelmaking unit was completely renovated in 2020 and is equipped with a three-stage gas cleaning system, which made the steel production process more environmentally friendly. The enterprise produces over 3 million tons of steel annually. ChMK produces rolled sections and sheets from carbon, structural, tool and corrosion-resistant steel grades, as well as structural shapes and rails. The plant's products are in demand in various industries. These are nuclear energy, heavy, chemical, energy, automotive and agricultural engineering, bearing and pipe rolling plants, construction, medical equipment.
