Product Description
1. Technical Parameter
Furnace Type: The periodical operated bright annealing furnace adopts roller hearth type. Throughout of the furnace is 1500Kg/h.
Purpose: It is mainly supplied for bright annealing kinds of copper tube, wire, bar, and coil. Such as: copper, brass, bronze, cupronickel, and copper alloy. Maximum working temperature of the furnace is 950ºC.
2. Brief Introduction of Equipment
2.1, Charge Table
At the charge end of the furnace a driven roller topped table allows coils or straight tube/bar to be loaded onto trays, which are designed to carry the load through the process. Each roller on the table is mounted on bearings supported by the main structure and is driven by chains connected to a fast drive system which transports the loaded tray into the charge purge chamber.
2.2, Charge Purge Chamber (CPC)
Doors are fitted at each end of the Charge Purge Chamber to seal in the atmosphere. These doors are opened and closed by an external pneumatic cylinder and are fitted with pneumatically operated clamps.. At this stage, products are remaining in standstill.
The CPC entry door opens for the product batches to be transferred from the charge table into the charge purge chamber and then closes.
After purging the charge purge chamber discharge door and furnace chamber doors are opened simultaneously and the loads (in the charge purge chamber, furnace and radiation cooling chamber) are indexed forward. The charge purge chamber's discharge door and furnace chamber doors are then closed before the charge purge chamber's inlet door can be opened again to accept the next load from the charge table. .
The Charge Purge Chamber is a gas tight steel case construction with rollers and external roller drive systems. The rollers are mounted in sealed bearings to maintain atmosphere integrity.
2.3, Heating Chamber Entry Plenum
In order to ensure adequate thermal separation between the charge purge chamber (CPC) and the furnace, an entry plenum and furnace door is provided.
The entry plenum is a gas tight steel structure insulated on the inside and fitted with an insulated fiber.
To minimise the loss of atmosphere integrity during loading and minimise re-purge time, two filament curtains are fitted behind the doors; and ceramic fiber isolating wall which driven by pneumatic cylinder is mounted in this section. An insulated membrane explosion relief port is designed at top of the furnace.
