Double-door double-trolley heat treatment furnace insulation solution

Double-door double-trolley heat treatment furnace introduction :

Double-door double-trolley heat treatment furnace is mainly suitable for normalizing, annealing and tempering of metal materials such as die steel, alloy steel, special steel, high manganese steel liner, high chromium ball, low chromium ball, roll, etc. in the absence of oxidation or less oxidation. The furnace temperature is between 1200-1300℃.

 

Double-door double-trolley heat treatment furnace -structure and sealing

The shell of the double-door double-trolley heat treatment furnace is welded by steel plates and steel sections, and the trolley is welded by steel sections and steel plates. The trolley can reduce heat radiation and convection losses through soft contact with the full-fiber furnace lining and sand sealing mechanism , effectively ensuring the sealing of the furnace body.

 

Double-door double-trolley heat treatment furnace full fiber lining

The lining of the double-door double-trolley heat treatment furnace adopts a composite structure of full-fiber ceramic fiber module + ceramic fiber blanket . This full-fiber structure can save about 60% energy compared to the traditional brick furnace structure.

This method can use 300X300x300mm Anchor-Tech ceramic fiber zirconium-containing module + 20mm thick ceramic fiber zirconium-containing blanket .

full fiber module of the double-door double-trolley heat treatment furnace , including angle iron type, butterfly type, hanging type, sliding type , herringbone type, bench type, hook type, corner type, etc., which can be used according to different furnace types. According to different application conditions, Anchor-Tech can provide customers with the best module anchoring solution .

 

Advantages of full fiber thermal insulation

(1). Good wind erosion resistance

Generally, the wind erosion resistance of fiber products is related to the density of the products. The wind erosion resistance of ceramic fiber blankets alone is 15 m/s. However, the wind erosion resistance of the lining of a double-door double-trolley heat treatment furnace can be increased to 25 m/s by using all-fiber composite thermal insulation.

(2) Improve sealing effect

The folding direction of the ceramic fiber module is perpendicular to the fiber direction of the layer blanket . The high-temperature gas in the heat treatment furnace cannot escape directly through the folding gap of the module. The layer blanket can effectively improve the overall sealing effect of the furnace lining. Even when the fiber lining reaches its service life cycle and is damaged and shrunk, the backing layer blanket can prevent the high-temperature gas from causing major damage to the furnace body.
