Aluminum electrothermal board metal casting heater is tubular electric-heating element heating element, and bending forming, into the mold with high quality metal alloy material with centrifugal casting for shell into various shapes, round, flat, orthogonal model, air, water and other abnormal etc. After finishing it can and heated body closely 6-colours, aluminum casting surface load can reach 2.5-4.5 w/cm2, maximum operating temperature between ℃ 400 to 500, Copper casting surface load can reach 350-5.0 w/cm2, maximum operating temperature 600-700 between ℃, Cast iron surface load can achieve 4.5-6.0 w/cm2, maximum operating temperature 800-850 ℃ between. Metal casting heater is a kind of high efficient heat division uniform heaters, thermal conductivity of excellent metal alloys, ensure hot surface temperature uniformity, eliminate the equipment of hot and cold spots. Have long life, insulation performance is good, the mechanical properties of strong, corrosion resistance, resistance to magnetic field, etc. The heat insulation device, face increasing sintering infrared cooling surface within this can save electricity 35%.
The main use:
Widely used in plastics machinery, mould, cable machinery, alloy die-casting machine, piping, chemical industry, rubber, petroleum and other equipment.
Three, use note:
1, working voltage shall not exceed 10% of the ratings, Air relative humidity is not more than 95%, no explosive and corrosive gas.
2, wiring insulation parts in the heated layer, outside, the shell should be effective grounding; Avoid with corrosive, explosive medium, moisture contact; Lead wiring should be able to long-term bear wiring part of the temperature and heating load, connection screw fastening should avoid overexertion.
3, metal casting heater must be kept in dry places, and if by long-term placed, insulation resistance is under the 1-m Ω, may in 200 degrees Celsius in baking ovens around 5-6 hours, can resume normal. Or lowering voltage electrify heats, until the recovery insulation resistance.
4, metal casting heater should make positioning, effectively fever area should be fixed tightly with heated body joint, forbidden empty burn.
铸铝电热板金属铸造加热器是以管状电热元件为发热体，并弯曲成型，进入模具用优质金属合金材料为外壳以离心式浇铸成各种形状，有圆型、平板、直角型、风冷、水冷及其它异型等。经精加工后它能和被加热体紧密贴合，铸铝表面负荷可达到2.5-4.5w/cm2，最高工作温度400-500℃之间；铸铜表面负荷可达到3.5-5.0w/cm2，最高工作温度600-700℃之间；铸铁表面负荷可达到4.5-6.0w/cm2，最高工作温度800-850℃之间。金属铸造加热器是一种高效热分部均匀的加热器，热导性极佳的金属合金，确保热面温度均匀，消除了设备的热点及冷点。具有长寿命、保温性能好、机械性能强、耐腐蚀、抗磁场等优点。将外散热面增加保温装置，内散热面烧结红外线这样可节约用电35%。
二、主要用途：
广泛应用于塑料机械、模具、电缆机械、合金压铸机、管道、化工、橡胶、石油等设备。
三、使用注意事项：
1、工作电压不得超过额定值的10%；空气相对湿度不大于95%，无爆炸性和腐蚀性气体。
2、接线部分放在加热层、保温层以外，外壳应有效接地；避免与腐蚀性、爆炸性介质、水份接触;引接线应能长期承受接线部分的温度及加热负载，接线螺丝紧固时应避免用力过猛。
3、金属铸造加热器应放在干燥处、若因长期放置，绝缘电阻低于1MΩ时，可在摄氏200度左右的烘箱中烘烤5-6小时，即可恢复正常。或降低电压通电加热，直至恢复绝缘电阻。
4、金属铸造加热器应做好定位固定,有效发热区必须与受热体紧密贴合，严禁空烧。
