Pusher-type double sided reheating furnace

Pusher-type reheating furnace

Application: Heating bloom and billets before the rolling.

The process of Billet movement: The tube slides or rails are paved overhead along the longitudinal direction. The billets are placed on the slides or rails and pushed forward by the pusher. The billets are heated when they move through the different heating zones then rolled outside of the furnace.

Furnace classification:

Combustion mode: regenerative combustion and conventional combustion.

Heating mode: single sided heating and double sided heating.

Advantages: Simple structure, wide application, low investment etc.

Applicable Fuel: Producer gas, blast furnace gas, mixed gas of blast furnace and Coke oven, nature gas, heavy oil and various light fuels etc.

Pusher-type double sided reheating furnace

Pusher-type double sided reheating furnace is mainly used for heating billets with the thickness more than 120mm and the production capacity usually more than 20t/h. The billets are heated simultaneously by the upper and lower burners in the furnace. It will improve the heating rate and decrease the billets’ resident time in the furnace, and therefore reduce oxidation loss. However, an overhead water cooling system is required for the movement of the billets in the furnace, which will complicate the structure and increase the equipment.

This type of furnace is suitable for large production capacity. With the increase in the production capacity, the energy consumption will be gradually reduced.
