Products Name:DKT series double deck heat exchanging continual furnace
 
 
    Product description

 ·Double deck continual annealing furnace can be divided into two series, the "double deck heat exchanging continual annealing furnace" series and the "U-shape double deck roller-hearth continual spheroidal annealing furnace" series. Both series are qualified as environmental friendly and low dissipation products and have been granted the national patents with patent ID ZL200810120771 and ZL200610053067 respectively. The technologies involved are among the best ones domestically.

·This device is regarded as an environmental friendly and energy saving device for the annealing of bearing steel, alloy tool steel, alloy structure steel, high speed steel, carburized steel pipe, steel bars and forged workpieces.

·The double deck heat exchanging continual annealing furnace integrates two single deck roller-hearth furnaces together; one furnace above the other with their feed end placed at opposite ends. There is no heat isolating furnace-lining between the two decks, so that the heat dissipated from the annealed workpiece on one deck can be used to pre-heat the cold workpiece on the other deck. This heat exchanging process is carried out in the heat exchanging chamber right next to the annealing chamber. The heat exchanging process is able to reduce the power consumption per weight from 210-240kw h/ton to less than 150kw h/ton when the bearing steel bar is being spheroidal annealed. Its ability to save energy is dramatic.
