Single head heating tube, also known as single head electric heating tube or cartridge heating tube, is a type of electric heating tube (tubular heating element). In China's electric heating industry, there is a long-standing model designation: M3. In the late 1990s, due to the widespread application of electric heating tubes in China, many shapes of electric heating tubes emerged. In southern China, this type of electric heating tube with one end lead-out used for molds is called single head heating tube or single end electric heating tube, which is very descriptive.
Basic Introduction
Abroad, it is called cartridge heater, also a descriptive name, because the cartridge shell is cylindrical with one end sealed, which is similar to the Chinese term single head electric heating tube.
Applications
Single end lead-out electric heating tube is suitable for heating media where both ends cannot be connected, such as high and low temperature insertion heating in various molds and mechanical equipment, including stamping dies and other molds, medical equipment, plastic sealing machines, bottle cap sealing machines, continuous automatic sealing machines, cigarette making machines, etc. Mainly as follows:
1. Used for drying wood, paper, printing and dyeing, paint residue, etc.
2. Melting heating of saltpeter and other salt substances.
3. Melting low melting point alloys, such as lead melting furnace, tin melting furnace, etc.
4. Building heating.
6. Infrared radiation heating devices.
7. Low temperature electric furnaces such as industrial electric furnaces with air circulation, electric furnace boxes, etc.
8. Heating devices in oil, water and other chemical liquids, electroplating bath liquids.
9. Seawater electric distillation devices.
10. Heating devices for alkali and acid.
11. In the food industry, used for baking various breads, biscuits, pastries, and as electric heating devices in continuous tunnels.
12. In plastic product processing and molding extrusion devices and rubber product molding vulcanization devices.
13. In medical and health disinfection equipment, such as sterilizers, disinfectors, etc.
14. Heating of motor vacuum impregnation equipment, enameled wire drying devices, etc.
15. Various household electric heating appliances in daily life, such as electric stoves, electric ovens, electric rice cookers, electric frying pans, electric griddles, water heaters, electric irons, etc.
