1. The electric heating element is used as an electric heating element that converts electric energy into thermal energy. According to the temperature to be used, the materials used for the electric heating tube (stainless steel, ceramic, quartz, carbon fiber, titanium, copper, Teflon, etc.) and voltage (electric heating tube) are determined. Actual voltage and input voltage), power;
2. Determine the diameter, length and lead length of the electric heating tube according to the specific use environment and the space requirements for the installation of the electric heating element;
3. According to the appearance characteristics of the electric heating tube, first clean the surface of the electric heating tube, then turn on the power supply, dry it in the air, and turn off the electricity after the surface is red. After the electric heating tube is completely cooled, wipe it with a napkin, and the white paper should be No black oxidized powder (not reacted with oxygen in the air), indicated as a high quality electric heating tube.
The electric heating tube is made of high-quality domestic thick-walled seamless stainless steel tube, imported high-temperature magnesia powder and sealing material from the United States, so that the electric heating tube can withstand temperature up to 900 °C, and the electric heating tube will not be damaged after dry dehydration; The black mesh belt furnace is subjected to a high temperature nitriding treatment process at 1060 ° C, which improves the high temperature resistance and corrosion resistance of the electric heating tube and ensures the service life.
The heating pipe is made up of a heating wire in a seamless metal pipe (carbon steel pipe, titanium pipe, stainless steel pipe, copper pipe), and the gap portion is filled with a magnesium oxide powder having good thermal conductivity and insulation, and then processed into a shrink tube. Various shapes required by the user. The utility model has the advantages of simple structure, high thermal efficiency, good mechanical strength and good adaptability to harsh environments. It can be used for the heating of various liquids and acid-base salts, as well as for the melting of metals with low melting point (lead, zinc, tin, babbitt)
