High temperature insulation solution for trolley furnace
 Overview of the trolley furnace:

high temperature insulation solution,ceramic fiber module,ceramic fiber blanket

Trolley type furnace is a gap type furnace, mainly used for steel ingot forging or workpiece heat treatment, so the furnace can be divided into car-type heating furnace and car-type heat treatment furnace. The furnace consists of a furnace, a movable carriage and a door.

The main difference between trolley heating furnace and trolley heat treatment furnace is the furnace temperature, furnace temperature: 1200-1300 degrees, heat treatment furnace temperature: 650-1200 degrees.

Trolley heat treatment furnace insulation

Roof, furnace wall, the door: use zirconium high purity lines fiber module, insulation thickness of 300/250mm, compensation blanket with high purity zirconium ceramic fiber blanket; back carpet with high purity ceramic fiber blanket, insulation thickness 30/50mm, insulation thickness and material selection is based on the heat treatment temperature.

Technological superiority

The top of the furnace and the furnace wall joints sealing treatment: The connection between the furnace and the furnace wall is the weak area of the lining, which is easy to form air leakage or channeling fire, so that the insulation effect of the lining is reduced, and the service life of the lining is affected. In order to prevent the site from appearing through the seam, wall and wall, wall and the top of the junction with ceramic fiber module and ceramic fiber backing blanket stitching way. At the same time to prevent the hot surface layer of ceramic fiber module, high temperature contraction at the junction, in the wall at the junction of a compensation section, the same material with the module fiber blanket fold, to maintain more than 30% compression ratio, forced into the area to ensure that the high temperature sealing effect, the furnace wall and the top of the junction processing as shown below.
