Severstal has started the assembly of the air heater of blast furnace #5

​The assembly of metal constructions of the air heater #2 of blast furnace #5 has started at the Cherepovets metallurgical plant (in the structure of the division Severstal Russia Steel).

The general contractor of the reconstruction is the Center “Domnaremont” (in the structure of the division Severstal Russia Steel) will hold the assembly of 1,500 tons of metal constructions and over 250 tons of equipment. By today hard bottom of the aggregate and 2 out of 23 belts of the future shell have been installed. The air heater will be installed by the design worked out by “Kalugin” CJSC.

This is the last unit that will need to be renewed in the framework of the modernization program o the air heater of blast furnace #5 with the total value of about 2 bln rubles, the CEO of the division Severstal Russia Steel, S. Toropov, said. Each out of 4 new air heaters will have the inbuilt dome burning camera instead of external camera. It will allow to reduce the number of the required refractory materials by twice – from 10 to 5 thousand.

The air heater #2 is planned to be started in late 2016. After its launch the hot-blast temperature of blast furnace #5 is expected to grow from 1,180 to 1,250 degrees Celsius that will provide the reduction of coke consumption and consequently the prime cost of cast iron.
