cast iron heater

Suitable for high temperature and high heat, the surface load can reach -/, high temperature resistance, average thermal conductivity, and the process structure is similar to cast copper heaters and cast aluminum heaters. Manufacturing process of cast iron heater:
The high-temperature molding machine uses a cast iron heating ring to bend the prepared heating tube into the required requirements. Put it into the mold to be formed, cast it with molten iron, then grind it, smooth it and finish it, and finally get the finished product. Cast iron heaters use tubular electric heating elements as heating elements. The elements are bent and formed into molds to be centrifugally cast into various shapes, including round, flat, right-angle, air-cooled, water-cooled and other special shapes. After fine machining, it can fit closely with the heated object, and the surface load can reach 3/. It has fast heating, uniform heating, good thermal conductivity and long service life.
Instructions for use and precautions:
The working voltage shall not exceed the rated value, the relative humidity of the air shall not exceed the rated value, and there shall be no explosive or corrosive gases.
The wiring part should be placed outside the heating layer and insulation layer. The shell should be effectively grounded to avoid contact with corrosive, explosive media and moisture. The lead wire should be able to withstand the temperature and heating load of the wiring part for a long time. When tightening the wiring screws Excessive force should be avoided.
The metal casting heater should be placed in a dry place. If the insulation resistance is lower than the insulation resistance due to long-term storage, it can be baked in an oven at about 100 degrees Celsius for an hour to return to normal. Or reduce the voltage and apply electricity until the insulation resistance is restored.
. Cast iron heaters should be well positioned and fixed, and the effective heating area must be in close contact with the heating body. Empty heating is strictly prohibited. When dust or contaminants are found on the surface, they should be cleaned in time before use to avoid affecting heat dissipation and shortening the service life.
The magnesium oxide powder at the outlet end of the electric heating tube prevents pollutants and moisture from penetrating into the place of use, and prevents leakage accidents.
For non-standard products, customers please provide the specific technical parameters of the cast iron heater when ordering: voltage, power, specific shape and size, etc. Customers are welcome to discuss and order!
