Knowledge related to cast iron heaters

The heating effect of cast iron heaters is very good, which is related to the characteristics of iron. Iron has good thermal conductivity and high temperature resistance. There are many

The products all use iron, and the cast iron heater is designed based on this advantage, so the cast iron heater has good thermal conductivity and high temperature resistance.

Understanding of using cast iron electric heating rings: Check whether the power supply voltage at the site of use matches the rated voltage of this product. If it is different, it should be equipped with a power supply voltage that is the same as the rated voltage of this product. To ensure safety, it is important to ensure that the casing of electrical equipment is reliably grounded. When the electric heater product has been in use for more than three months, it should be self dried by intermittent power supply under allowable conditions. After heating for ten minutes, the power should be cut off for half an hour, and the moisture inside the heating element should be discharged three to four times continuously. The magnesium oxide powder at the outlet of the electric heating tube should be protected from pollutants and moisture infiltration in the use site to prevent leakage accidents. The metal casting heater should be positioned and fixed properly, and the effective heating area must be tightly attached to the heating body, and empty burning is strictly prohibited. When dust or pollutants are found on the surface, they should be promptly cleaned and reused to avoid affecting heat dissipation and shortening service life.

Stainless steel electric heating pipes are made of steel pipes. When there is no flow rate and the temperature is not working, the temperature of the container will become hotter and hotter. However, due to the radiation of the heating element, the container will crack under the conditions of flow interruption and pressure, leading to the leakage of process gas and causing accidents. It is usually recommended to calculate the wall temperature of the container without the protection of a flow switch, and it is recommended to add overtemperature protection on the container.
