The roasting temperature of carbon roaster can reach 1250℃, and the roasting cycle generally requires 320-420h. The heat preservation function of the furnace cover is particularly important. There are many hidden dangers in the process of using the original structure firebrick furnace cover.
01 carbon roaster open cover and buckle cover frequently in the production process, and the clay brick is not resistant to rapid cooling and rapid heating, serious cracking leads to flame intrusion and burning steel structure, short service life, large heat loss.
02 If the total lifting weight of firebrick furnace cover exceeds 20t, a 30t crane should be specially set to complete the lifting work of furnace cover.
In order to reduce burn up, prolong the service life of the furnace cover, reduce heat loss, lightweight ceramic fiber module furnace cover is widely welcomed.
Carbon roaster with ceramic fiber insulation structure
The furnace cover is clad in steel, lined with a 30 thick zirconium ceramic fiber tile blanket +180mm thick ceramic fiber module, fixed in 310 heat resistant steel.
Improved advantage with lightweight ceramic fiber module
Compared with the original furnace cover, the weight of the improved furnace cover is light, only 1/6 of the original furnace cover weight; The new type of furnace cover has low thermal conductivity, fast heating and cooling speed during hoisting, which significantly improves the heat sensitivity of the furnace. Good thermal shock resistance, hot and cold resistance and no cracking; And the construction is simple, high integrity, good sealing performance. The test shows that the new ceramic fiber module furnace cover can greatly reduce the heat loss of furnace body.
