Detailed Description
Continuous Color Coating line
1. Processing Characteristics
raw materials: strip width:800-1250mm
strip thickness:0.2-1.2mm
original material: GA, tinning-plated strip
outside diameter: φ800-1600mm
inside diameter: φ508/φ610mm
speed:25-100m/min.
coating processing: continuous two side two-coating-two-drying
coating thickness: face side layer dry coating thickness can be adjusted among 5-15μm, two side monolayer primer drying thickness can be adjusted among 5-10μm
capacity: 30～120 thousand ton per year
energy type: natural gas, electricity, liquid petroleum gas, coal, coal gas
degreasing form: two chemical degreasing +three water cleaning +pure water spray
energy save method: incinerator & heat recovery, energy-saving, emission reduction
2. unit characteristics:
1. advanced coating processing, mature and reliance technology, widely used in construction or other industry.
2. adopt vertical accumulator, effectively reduce the negative impact to the strip by the producing line
3. to guarantee the product quality, adopt continuous alkali spray, alkali brush and three water spray and a last pure water spray in preprocessing, strengthen the effect of degreasing, clean up the oil of strip surface thoroughly
4. in order to boost up the adhesive between strip surface and paint, set a chemical coating section, to form a layer of chemical transforming film, it plays a connecting role between strip surface and thereafter coating
5. chemical coating adopt rolling method, advanced processing, high chemical film quality, guarantee coating performance and quality. AC frequency electric engine driving, speed can be adjusted separately to adapt the processing requirement. Equipped with chemical fluid mixing system, guarantee the uniformity of the chemical fluid in the running process. Two coating head equipped with speedy switch to shun reel change welding, preventing damaging the working rollers. This processing have the characteristics of no pollution, no waste, chemical fluid absolutely use up, chemical film uniformity and compact.
6. coating roller include deflecting roller, supporting roller, adhesive roller, measuring roller, coating roller, have the lift adjusting painting tray, design a precise controlling and adjusting system for coating thickness, coating roller, adhesive roller, measuring roller are driven by AC frequency engine separately, coating thickness and smoothness can be realized by adjusting the ratio speed between each roller speed and processing speed, and also can be realized by different coating working way, through coating adjusting system, adjust the clearance and extrusion pressure among different rollers, adopt the pressure induction show up the coating roller extrusion pressure to precisely control the coating thickness.
7. drying furnace adopt the method of forced hot air cycling, heating method can choose several energy(natural gas, coal gas, electricity, liquid gas, etc.), furnace body adopt maze flashboard structure, thick insulation layer, effectively preventing radiating heat, set and auto-control the temperature according to different paint and strip thickness. Drying furnace equipped with the system of hot air cycling, fresh air supplement, agency waste emission, temperature auto-control, etc. when adopt incinerator & heat, not only can achieve the national standard, but can effectively save energy, reduce cost.
8. select the CPC,EPC, guarantee the stability of the line
9. adopt the AC frequency driving control system, friendly windows, simple equipment maintenance.
2. processing as follows:
pay-off reel → cutting → welding → seam-pressing → entry accumulator → degreasing(alkali spray → alkali brushing → water brushing → water spray → drying) → chemical coating → drying → primer coating →drying →cooling →finishing coating →cooling →exit accumulator →inspecting →shearing →tension ree
