7、Heating rate：≤8℃/min；
8、Enclosure temperature：Enclosure temperature is not higher than room temperature ' 15 ℃, except the seams and the oven
9、Power supply: three-phase five-wire system, 380V, 50HZ;
10、Gross power：The switchboard power in 51KW around.
Two、Constructional features of the silk screen tunnel drying furnace for iphone products
1、Enclosure material: it is made of 2mm thick Q235 cold-rolled steel sheet (with best strength, plasticity and welding comprehensive performance), which is bent and welded.
2、Surface treatment: after surface polishing, polishing and phosphating (can increase corrosion resistance of metal and adhesion of paint), high temperature drying molding (large ripple type) can prevent static electricity and corrosion.The color is "computer grey".
3、Inner liner materials: 1.5mm thick, 201# stainless steel plate;Keep the inner tank clean and free of dust, prevent rust and corrosion;
4、Oven base: made by 50*50*1.5mm square pass;The bearing strength of internal and external furnace surface is maintained, and the thermal expansion and cold shrinkage coefficient is retained to prevent furnace deformation.
5、Thermal insulation material:Aluminum silicate cotton of 100K encrypted;Features such as non-combustible, strong heat insulation, thickness of 100mm;
6、Conveyor belt:net of stainless steel (chain type);；
7、Lamp bracketof Heating tube : welding system of stainless steel square , adjustable height, adjustable range: 150 to 250mm;
8、Foot cup/castor: the bottom is equipped with adjustable foot cup/castor, which is convenient to adjust the height and movement of the box.
Three、Control system of the silk screen tunnel drying furnace for iphone products
1、Air motor: 0.37KW air motor (4 sets)
2、Wind wheel:multi-wing wheel in 9 inch;
3、Heating pipe: medium wave and heating pipe of far infrared is adopted, with 15 pieces per section and 850 watts per section;
4、Thermostat of Temperature control : using Taiwan H961 thermostat of microcomputer intelligent digital ;PV and SV in function of double LED display;Output with PID automatic tuning algorithm ,precise control;
5、Thermostat of over temperature protection: adopting the intelligent thermostat of Taiwan;PV and SV in function of double LED display;When the temperature exceeds the setting value of the thermostat, the heating power is automatically cut off.
6、Control of heating tube: SSR solid state is adopted to control the heating of every heating tube;
7、Temperature sensor: Omron 3-meter standard, k-type thermocouple;
8、Others: all the control appliances are imported schneider and omron.
Four、Funtion of the silk screen tunnel drying furnace for iphone products
1、Automatic temperature: the temperature controller can be set according to the temperature value set by the user;PID is used to calculate the output power automatically. The closer the temperature is to the set value, the smaller the output power will be.
2、Over-temperature alarm: when the actual detection temperature exceeds the setting value of the over-temperature protection thermostat, automatically cut off the heating power and function of double protection ;
3、Audible and visual alarm: alarm lamp with buzzer;
4、Ground protection: safety ground protection of structural components;
5、Phase loss and phase sequence protection of power supply: equipped with phase sequence protector.
