Technology working condition1 uses: wire cores bright annealing2 heating mode: electric heating.3 temperature control:2 area,PID control4 protective gas: N2 General parameters1. name:pit type bright annealing furnace2. type:120KW3. furnace barrel size:Φ900*H1800mm4. annealing temperature:950ºC(MAX)5. total equipment:pit type bright annealing furnace and control system Equipment details: 1 furnace body:1.1 the furnace shell is welded by steel plates and sharp irons. The surface have polish and rust treatment, paint high temperature paint(300ºC paint)1.2 The furnace outer line is build by Shaped brick and refractory material, the outer line sharp build according to the vessel.1.3 Inner line is piled with Refractoryfiber cotton and blanket,thickness:325mm(25mm cotton blanket and 300mm sharp fiber,max temperature: 1260ºC,between the sharp fibers are fill with blankets. 2 Heat system:2.1 Power source:3P-380V2.2 Heat element:belt type heat element(0Cr21Al6Nb)2.3 Power controller:SCR heatcontroller(0-100%)2.4 Temperature control:2 zones, PID2.5.5 Heat element fix method:use ceramic nail to fix the heat elements on the linging, it can effectively prevent heat leakage 3 barrel:3.1 barrel body material:SUS321*10mmthickness,bottom: SUS321*10mmthickness3.2 barrel body have the hyperbolic wave forming treatment, it have high strength and not easy to deformation and cracking.3.3 The barrel have light design to reduce the bottom press.3.4 double sealed ceramic fiber packing and configuration of 8 sets of manual clamping device, good sealing performance3.5 The heat insulation cotton felt can effectively prevent leakage of steam drum.3.6 Thermocouple tube use thick stainless steel tube to increase the service life. 4 Diversion plates4.1 Material:SUS321*10mmthickness4.2 Use many plates system, welded as 30~45°,keep strong structure and improve the hot air uniformity.4.3 improve the furnace hot air uniformity 5 furnace cover:5.1 the furnace cover top use plate and strong with sharp irons. The furnace cover structure could fix the fan.5.2 Round shape bottom head material is SUS321*8mm thickness.5.3 The head is formed by spinning, this type of structure is lighter and reduce the weight5.4 The furnace cover line is lay by Refractory fiber cotton to reduce the heat loss.5.5 The sealing flange and the inner barrel are in exact agreement, which can effectively keep the pressure in the furnace5.6 The gas pipes use thick stainless steel tubes. 6 Swing arm6.1 the steel structure is welded with steel plate bending, and the internal structure is strengthened by steel plate. 6.2 the rotating shaft can be used to ensure the strength of the cantilever6.3 the air pressure cylinder is used to lift and drive and protect the chain, which can prevent the drop when the air pressure is not enough.6.4 high strength chain to ensure its safety 7.fan cycle system 7.1 use double water cooling sealed motor, inverter control can effectively protect the motor.7.2 the circulating fan power is 18.5KW*4P, the axis material SUS310S7.3 fan speed: 0~1440rpm (according to the actual medium of equipment)7.4the axial flow impeller size: Φ700mm, the material is SUS310S, high structural strength7.5 impeller parameters: maximum flow: about 10000 m3/h ; wind pressure: about 300Pa 8.Control systemBasic automation control system to complete all control functions of the equipment with PID control.
