South Korea’s Nastech Co. Ltd. placed an order with EBNER to increase the annealing capacity of its existing HICON/H2® bell-annealer facility. The order comprises the supply of two HICON/H2 workbases, two heating bells and a cooling bell, plus the now necessary pressure-reducing station for hydrogen and nitrogen. The furnace facility accommodates medium- and high-carbon-steel strip coils with an outside diameter of up to 1,600 mm and a stack height of 3,200 mm.

This expansion phase brings the number of available HICON/H2 workbases to eight, each with a maximum net charge weight of 31.5 tons. The design of the bell-annealer facilities – with metallically encapsulated workload spaces – prevents decarburization.
