First Danieli bell annealing furnaces in Russia, for NLMK

NLMK Metiz selected Danieli Centro Combustion to supply a new bell annealing furnace installation for the Berezovki facility. 

This new system will heat-treat (recrystallize) steel wire coils in 100% N2 atmosphere. The charges will be 21-t coils in seven stacks of three coils each.

The project consists of two phases: In Phase 1, DCC will supply two bases, one heating hood, two inner covers, and one cooling hood. Phase 2 will match the first part of the project.

The furnaces will have a direct coupled base fan; special design diffuser and plenum; hydraulic locking system; and silicon-carbide head burners, each one with its own recuperator.

DCC will supply all mechanical, electrical and automation equipment, and provide technical assistance during erection and commissioning.
