Jiangsu Jiuding Industrial Furnaces Technology Co., Ltd. is one of the most experienced manufacturers and suppliers of box annealing furnace in China, also supports customized service. Welcome to wholesale high-grade box annealing furnace for sale here from our factory. Quality products and reasonable price are available.
Product Concept
In medium and narrow strip mills, small batch annealing is often carried out in box annealing furnaces. The annealed parts are stacked on a rack, which is hung in the annealing box cover. The box cover is placed on the annealing box. The box and the cover are lifted by a crane into a special furnace chamber, which is embedded in the floor. The annealing box does not bear the weight of the charge.
During annealing, protective gas is used, which is heated by remote gas, fuel oil or electricity. After the heating and insulation are completed, the hot box is placed in the heat exchange pit, which transfers the heat to the cold box that should be annealed later. Through natural rise, the hot air is discharged upwards, and the cold air enters from the air inlet from below. The cooling process to room temperature is carried out in a separate cooling pit with a fan.

Product Structure
1. Furnace structure
The furnace body of the box-type annealing furnace is generally in the shape of a rectangular parallelepiped. The outer shell is welded from steel plates and the internal lining is made of refractory materials, which improves the thermal insulation performance and ensures the stability of the furnace body.
2. Heating system
The heating methods mainly include electric heating and gas heating.
3. Furnace door design
The heavy furnace door fits tightly with the furnace body. The sealing material around the furnace door can prevent heat leakage and outside air from entering.
4. Temperature control system:
It consists of a temperature sensor, a temperature controller and a controller.
5. Ventilation system:
The ventilation system of the box-type annealing furnace includes an air inlet and an exhaust port.
