Imported heating wires mainly include the well-known KANTHAL heating wires from Sweden, Isabellenhuette from Germany (currently the most advanced manufacturer of precision micro-resistance resistors in the world) and Sedes from the United States. Sedes is a brand that is the world's leading developer and manufacturer of industrial heating. Its products are made of advanced stainless steel and special alloys in the most demanding environment). Some major international brands and professional manufacturers have many years of production experience and technology accumulation in their fields. The environmental requirements for the product are relatively strict, and it has its advantages compared with domestic products.
The advantages of the imported KANTHAL heating wire and the domestic heating wire are mainly mentioned in the following six aspects:
1. The energy conversion efficiency of KANTHAL heating wire is higher than that of domestic heating wire. The maximum temperature is 1425℃2600 F, which is higher than the nickel-chromium alloy 1250℃2280 F.
2. KANTHAL heating wire and domestic heating wire are used under the same specifications, and the service life of imported heating wire is 4-8 times that of domestic heating wire.
3. KANTHAL heating wire has a high surface load.
4. KANTHAL heating wire has high resistivity.
5. Kanthal KANTHAL heating wire has a lower density and saves material costs.
6. No oxide debris will be produced. Oxides can contaminate goods and electric furnaces, and may cause short circuits or failures of electric heating elements and gas burners. For the use of electric furnaces, the result of using Kanthal iron-chromium-aluminum alloy is lower operating cost, less material consumption, and longer life.
The advantage of Kanthal heating wire (Kanthal) is still very obvious. Of course, the cost is slightly more expensive than domestic heating wire. In the selection of heating wire material, we suggest that the best debugging should be done according to the product and equipment.
