Mechel Commissions Blast Furnace at Chelyabinsk Metallurgical Plant

04/07/2009 - Mechel OAO officially commissions Blast Furnace No. 4, which features a new cooling system, at its Chelyabinsk Metallurgical Plant subsidiary.

Mechel OAO has officially commissioned Blast Furnace No. 4 at its Chelyabinsk Metallurgical Plant subsidiary.
 
As part of its capital repair, the unit's power equipment was replaced, including the coolers and cooling system, and some 233 coolers installed. The main runners at the cast house were replaced, the blast furnace top equipment was renewed, charging system equipment was revised and installed, and the air heaters block was repaired. Replacement of the blast furnace lining using refractories made by Mayerton, featured the application of a number of new technical solutions.
 
Preparation for the capital repair was performed on a tight schedule. Blocks and components required for the repair were manufactured at Chelyabinsk Metallurgical Plant's subsidiary, Spetsremzavod OOO.
 
"The implemented measures will provide a 10% increase in the actual productivity of Blast Furnace No. 4 and extend its overhaul life, which will positively influence the economic performance of the Chelyabinsk Metallurgical Plant's blast furnace workshop,” commented Mechel OAO Senior Vice President Vladimir Polin. “The completed reconstructions and capital repairs of the equipment will allow CMP to give maximum effective response to the growing demands for metal products and ensure future production consistent with the market needs.
 
The renewed blast furnace will produce about 3000 tonnes of pig iron daily. Its restart was delayed temporarily last November to accommodate the plant's revised production programs and planned lower output. The unit was used for its capital repair while it temporary stayed idle.
 
Prior to the commissioning of Blast Furnace No. 4, the Chelyabinsk plant operated with two blast furnaces with a combined daily capacity of over 7500 tonnes of pig iron. These two blast furnaces ensured sufficient production from the plant's steel meltshops to meet current orders.
 
Mechel, one of Russia’s leading companies, unites producers of coal, iron ore concentrate, steel, rolled products, ferroalloys, nickel, hardware, heat, and electric power. Its business includes four segments—mining, steel, ferroalloys and power—and its products are marketed domestically and internationally.
