Heating elements are arranged up and down in the electric heating roller kiln tunnel for heating, the temperature of each temperature zone is set according to the process, and the charging bowl is continuously transported on the roller bar.
Technical parameters of equipment
Total length of equipment: customized
Rated power: Make on demand
Temperature rise of kiln surface: ≤50℃
Control precision: ± 1 ℃ (at constant temperature)
Section temperature difference (Empty furnace): ± 5 ℃ (constant temperature in high temperature zone)
Long term service temperature: ≤1000℃
Furnace atmosphere: air. A small amount of waste gas, such as water vapor, will be generated during the burning process of materials. The waste gas contains weakly alkaline gas, but does not contain corrosive components such as halogen and reducing sulfur.
Number of loading layers: 2nd floor
Number of conveying trains: 2 columns
Common conveying speed: 600-1500mm/h (continuously adjustable)
Main structure of equipment
Kiln body, temperature zone, heating system, air inlet and exhaust system, fire-resistant insulation structure, furnace body structure, furnace body transmission system and temperature control system.
1. Fire resistant insulation structure
（ 1) The furnace structure and furnace material shall be specially designed according to the material burning process.
（ 2) The furnace is made of high-quality mullite brick+light mullite brick and fiber cotton. Anti corrosion, good heat insulation effect, small heat capacity, energy conservation and environmental protection. The furnace roof is of arch structure to ensure the uniformity of high temperature field.
2. Furnace structure
Main frame of furnace body: welded by sections and plates, fabricated in sections, assembled on site, convenient for transportation and removal.
Heating element: High temperature resistance wire is used for horizontal heating up and down. The ceramic protective tube shall be coated to avoid the corrosion of volatile matter.
Contact sealing between roller and furnace body: the gap between both sides of roller and furnace body is sealed with fiber cotton.
Feeding table and discharging table: they are installed at both ends of the kiln body, and the feeding and discharging roller tables are connected to the kiln body with bolts.
3. Furnace transmission system
Transmission mode: mechanical (sprocket, helical gear) transmission
Transmission medium: power transmission of alumina ceramic roller
Power source: frequency conversion motor direct coupled reducer
Conveying speed: frequency control
