– Trolley furnace overview –

Trolley type furnace belongs to the gap type variable temperature furnace, mainly used for heating ingots or workpiece heat treatment before forging, so its furnace type can be divided into the trolley type heating furnace and the trolley type heat treatment furnace. The furnace is composed of a furnace chamber, a movable trolley and a furnace door.

The main difference between trolley type heating furnace and trolley type heat treatment furnace is the temperature inside the furnace, the furnace temperature is 1200~1300℃, heat treatment furnace temperature is 650~1200℃.

– Trolley furnace lining insulation structure –

Trolley type heating furnace:

Furnace top, furnace wall, furnace door: adopt zirconium containing ceramic fiber module RDGW-589, insulation thickness 300mm; Compensation blanket with zirconium containing ceramic fiber blanket RDGW-512; High purity ceramic fiber blanket RDGW-312 is used as backing blanket with insulation thickness of 50mm.

Furnace bottom: firebrick.

Trolley type heat treatment furnace:

Furnace top, furnace wall, furnace door: adopt zirconium/high-purity ceramic fiber module RDGW-589/389, insulation thickness 300/250mm; Compensation blanket with zirconium/high purity ceramic fiber blanket RDGW-512/312; High purity ceramic fiber blanket RDGW-312 is used as backing blanket with insulation thickness of 30/50mm. Insulation thickness and material selection, according to the heat treatment temperature to determine.

Furnace bottom: firebrick.

– Technical advantages –

Sealing treatment of the joint of furnace top and furnace wall: the connection of furnace top and furnace wall is the weak area of lining, which is easy to form air leakage or fire channel, which reduces the insulation effect of furnace lining and affects the service life of furnace lining at the same time. In order to prevent the joint from appearing in this part, the connection between wall and wall, wall and top adopts the staggered connection mode of ceramic fiber module and backing blanket. At the same time, in order to prevent the high-temperature shrinkage at the junction of the ceramic fiber module of the thermal surface layer, a compensation seam is set at the junction of the wall top, which is folded in half with the fiber blanket of the same material as the module, maintaining the compression ratio of more than 30%, and forced into, to ensure the high-temperature sealing effect of the part. The connection between furnace wall and furnace top is handled as follows:
