The pusher type bright annealing furnace is used for heat treatment of copper tubes, coils. although, for heating of slab.
Pusher-type bright annealing furnace
This furnace design has proved itself as being particularly suited for the continuous treatment of parts under a protective gas atmosphere. The extremely stable hearth structure is designed for high charge weights. Depending on the operator's requirements, Nianda can provide single or multi-track furnaces. Multi-track designs offer a very high production flexibility.
The benefits of this furnace type include:
high operational safety through sturdy design very even distribution of the protective atmosphere thanks to good recirculation optimum reproducibility cost-efficient solution for treating large throughput volume1 Equipment Characteristics
1.1 It adopts imported gas burner for heating which has the rapid temperature rise.
1.2 The workpieces are heated from both top and bottom, it is ensured the uniform heating of workpieces.
1.3 It is loading from one end and unloading from the side of the other end, which is simple design, easy loading, energy-saving and reduced heat loss.
1.4 The automation can be achieved through the communication of human and machine via PLC.
1.5 Gas consumption calculating:
Basic data for design:
Gas calorific value: 1250Kcal/Nm3
Production rate: 100T/h
Material of billet: carbon steel
Maximum working temperature
Thermal content of billet: 205Kcal/kg
Thermal efficiency: 40%
Computational process:
Maximum thermal consumption of billet:
205Kcal/kg×100×1000Kg/h=20500000Kcal/h
Equivalent gas consumption: 20500000Kcal/h÷1250Kcal/Nm3=16400Nm3/h
Maximum gas consumption of the equipment:
16400÷40%=41000 Nm3/h
