Equipment process description and structure design3.1. Pre-treatment soaking tankTank size: L2900×W1400×H2300 (mm).    The skeleton of the immersion tank is a 50×100 galvanized carbon steel square tube, and the tank wall is made of 15mm thick engineering PP rubber sheet.  3.2. Hoisting equipment: 1 electric hoist with a power of 500w and a maximum hoisting weight of 300kg.3.3. Support frame: material 10# I-beam, specification size is L4100×H6000 (mm), quantity is 12 sets.3.4. Track: The material is 10# I-beam, the length is 15 meters.3.5. Conveying equipmentConveying equipment is mainly composed of electric drives, heavy hammer tensioning mechanisms, chains, rails, curved rails, telescopic rails, inspection rails, automatic refueling devices, brackets, electrical control systems, automatic overload protection devices, etc. The UH-5075-HA standard heavy-duty suspension conveyor chain is adopted, with a double-point hoisting weight of 100Kg, and a slag receiving plate is installed under the conveyor chain to prevent oil residue from the chain in the track from falling onto the workpiece; electric drive 1.5kw, chain speed Vmax≈1- 1.5m/min, install two sets of electric drives. All key parts of the line are equipped with catenary emergency stop switches, and the drive installation is equipped with mechanical and electrical double safety protection.Schedule 1:Conveyor chain model UH-5075-HA heavy-duty suspension chain with a pitch of 150mm and a total length of 93 meters.Hanging load-bearing The spreader has a load-bearing capacity of 50kg with an interval of 300mm.The track adopts C-shaped structure and 3.5mm steel plate. Total length 75 metersTension adjustment equipment Heavy hammer type, diameter 4200mm.Drive equipment: crawler type, reduction ratio 1:50, motor power 1.5kw, frequency conversion speed regulation.Chain speed The design process chain speed is: V=1.2m/min (1.0-1.5m/min steplessly adjustable)Fuel dispenser 1 set5. High temperature baking furnaceThe frame of the high-temperature baking furnace chamber and the support frame are made of profiled materials, which are made of 50×100 materials with a thickness of 3.0mm. The insulation board is made of 125mm rock wool socket insulation board. The inner and outer boards of the insulation board are galvanized sheets with a thickness of 0.7mm. The middle layer is filled with 100K rock wool insulation material. 15°C higher than the ambient temperature. Install 1 set of heat-breaking air curtain at the entrance and exit, using the hot air in the isolation furnace; the material of the heat-breaking air curtain is 1.5mm thick galvanized sheet, the blower is a 4-72-3.2A centrifugal fan, and the air volume is 3000M3/h motor The power is 3kw.  6. Heating system The heating device adopts LPG direct combustion method for heating. The outdoor side panel of the hot blast stove is made of 1mm thick color-coated steel plate; the thickness of the insulation layer is 100-150mm, and the material is rock wool and aluminum silicate. The inner plate of the combustion furnace holding cabinet is made of 1.0mm thick 304 stainless steel plate; the burner adopts a linear proportional adjustment gas Japanese Zhengying burner with a maximum output of 300,000 kcal, which can automatically adjust the size of the combustion flame according to the temperature to achieve the baking temperature More stable. The temperature control system is equipped with 2 sets of temperature controls to control the temperature in the hot blast stove and the baking oven (the system will automatically be constant at the set baking temperature); the circulating fan is connected to the burner interlockingly, and the system will automatically shut down the combustion when the circulating fan fails The system is equipped with protection circuits such as over-temperature and short-circuit of phase loss. The circulating fan adopts a GW-8C, 15kw plug-in temperature-resistant fan, with a circulating air volume of 25000000M3/h. The temperature in the baking room is automatically controlled by the digital temperature controller from heating and temperature control, and the sound and light alarm will prompt when the temperature is over.Attached Table 2: High-temperature baking furnace configurationBaking chamber body The specification of the high-temperature baking furnace is 12000*6050*3900mm (L×W×
