The trolley furnace is a gap-type variable temperature furnace, which is mainly used for heating before forging or heat treatment of workpieces. Therefore, its furnace type can be divided into a trolley heating furnace and a trolley heat treatment furnace. The furnace consists of a furnace, a movable trolley and a furnace door.

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

Insulation scheme of trolley heating furnace:

1) Furnace roof, furnace wall, furnace door: use zirconium-containing ceramic fiber modules, with an insulation thickness of 300mm. The compensation blanket adopts ceramic fiber blanket containing zirconium. The backing blanket is made of high-purity ceramic fiber blanket with a thermal insulation thickness of 50mm.

2) Furnace bottom: use refractory bricks.

Insulation scheme for trolley heat treatment furnace:

1) Using zirconium-containing/high-purity ceramic fiber modules, the insulation thickness is 300/250mm. The compensation blanket uses zirconium/high purity ceramic fiber blanket. The backing blanket adopts high-purity ceramic fiber blanket, and the insulation thickness is 30/50mm.

2) Furnace bottom: use refractory bricks.

In order to prevent the joint between the furnace roof and the furnace wall from appearing through joints, the ceramic fiber module and the ceramic fiber backing blanket are connected by staggered joints between the wall and the wall and the wall and the ceiling.
