Structure Introduction:
The Annealing Furnace consists of furnace shell, furnace lining, heating element, furnace cover and lifting parts etc.
For the lining of the fiber structure, namely the side wall for fiber block structure. The high aluminum brick heavy and light brick in the bottom part of the pressure, and the insulating brick masonry.

Heating elements:
The furnace body (side wall) part of all the use of resistance band (material 0Cr21Al6Nb), the heating element of the structure of the use of the current unique advanced technology. The original fiber lining heating element for hanging with positioning pieces of metal from the furnace shell steel structure into the furnace inner metal element and method of porcelain sleeve rod, so that in the condition of high temperature in the furnace, the metal positioning piece there are a large part of heat into the furnace shell steel structure, thermal short-circuit phenomenon is serious the heat loss. At present, our company adopted the way directly to the whole fiber fiber blanket into furnace wall (fiber compression 35~40%), using a special ceramic ceramic and ceramic screw tapping screw gasket, can quickly and easily the resistance belt is fixed on the furnace wall, this method does not produce heat loss, convenient construction, the use effect is the best. The maintenance is also very convenient. This method is widely used in all over the world.
The standard of refractory fiber lining material of low density, fire resistance of ≥ 1260ºC, the heat shrinkage will not expand, and a small coefficient of thermal conductivity (0.13Kcal/mhºC, and 0.6 fiber lightweight brick for 0.3Kcal/mhºC), less heat (full fiber furnace wall for 17261KJ/m², and 453633KJ/m2 - furnace refractory brick wall) of the superior performance. The cotton ≥ 320mm.
Compared with the same size of the brick wall of the furnace lining structure, fast heating speed, the installed power can be reduced by more than 20%, the energy saving effect of 20~30%.

Furnace is equipped with 10 mm stainless steel welded tank. The bottom plate of furnace gallbladder is flat-bottomed with reinforcing ribs at the bottom. The upper flange is machined and welded with steel sheet metal of Delta=30mm Q235. It is equipped with soft sealing positioning ring, furnace cover positioning and locking device, sealing groove, sealing ring sealing, and bottom charging device. In order to ensure the gas tightness of furnace gallbladder, a sealing ring is provided for sealing. Dynamic adjusting screw sealing furnace cover.

The furnace cover is made of steel sheet metal with a diameter of δ=30mm Q235. It is equipped with ignition, venting and explosion-proof devices and thermocouples to measure the temperature in the furnace. The furnace cover insulation box is welded by stainless steel plate and filled with refractory fibers.

The furnace body is provided with forced cooling outlet and exhaust outlet for rapid cooling.

Temperature control adopts two-zone zoning control and intelligent instrument is programmable. Through reasonable programming and parameter setting, the optimal control of each temperature zone can be achieved. By using its online self-tuning function, the optimal PID parameters of the furnace can be calculated and the ideal temperature stability can be achieved. The Paperless Recording Instrument Records Temperature.

Production attention:
The shaft furnace is used indoors, and the surrounding area is kept ventilated and bright. The required site must not be less than the floor area of the various specifications of the shaft furnace specified in the basic drawing.
