OJSC MMK-METIZ located in Magnitogorsk, Chelyabinsk region, already operates a HPH^® bell-type furnace plant supplied by Tenova LOI Thermprocess in 2014. This plant consists of two annealing bases, one heating hood and one jet-cooling hood with a maximum net charge weight of 36 t of wire rod or drawn wire coils. It uses a hydrogen/nitrogen mixture as protective gas atmosphere and features a useable diameter of 3,200 mm and a useable height of 2,700 mm.
In the spring of 2019, a new contract was signed concerning the expansion of the existing plant by further two annealing bases, one additional heating hood and one jet-cooling hood. The start of production of the new plant is scheduled for the beginning of 2020. Besides the spheroidization annealing of wire rod, this plant also carries out the recrystallization annealing of drawn wire coils with the HPH^® (High Performance Hydrogen) annealing technology.
Tenova LOI, a worldwide leading manufacturer for bell-type annealing furnaces, succeeded in getting this order thanks to its state-of-the-art HPH technology.
