How to wire the heating wire
Directly connect both ends of the heating wire into the line that needs to be used; The heating wire is red and heated, until the break is caused by the current in the circuit is too high, indicating that the current in the circuit exceeds the normal use range of the heating wire.
Working principle of heating wire: a heating device with high melting point made of iron-chromium-aluminum and nickel-chromium electroheating alloy materials, which will generate a lot of heat after being connected to the power.
Heating wire is suitable for hot air, air ventilation, drying room, heating and other industries in oven, drying tunnel, metal mold, water tank, oil tank, air, liquid, punching die and other molds, medical equipment, plastic sealing machine, bottle mouth sealing machine, continuous automatic sealing machine, smoke machine, machinery manufacturing, automobile, textile, food and other industries.
Iron-chromium-aluminum, nickel-chromium electric heating alloys generally have strong oxidation resistance, but because the furnace contains various gases, such as air, carbon atmosphere, sulfur atmosphere, hydrogen, nitrogen atmosphere, etc., these gases have a certain impact on the components under high temperature use
Although all kinds of electric heating alloys have been oxidation treatment before leaving the factory, but in the transportation, winding, installation and other links will cause component damage to a certain extent, and reduce the service life, in order to extend the service life, customers are required to pre-oxidize before use, the method is to install the electric heating alloy components, in dry air by electricity heating to lower than the alloy allowable use temperature of 100-200 degrees, keep warm for 5-10 hours, and then slowly cool with the furnace.
