In the work of the roller hearth furnace, its working principle is: directly or indirectly place the product on the roller, and the continuous rotation of the roller can make the burnt products advance in order. The end of each roller passes through the sprocket and is driven by the chain to run; in order to drive more smoothly and safely, the chain is often divided into multiple groups for transmission. The roller at low temperature is made of heat-resistant nickel-chromium alloy steel and other materials, and at high temperature, high temperature resistant alumina or silicon carbide ceramic rod is used as the roller. The most commonly used heating elements are silicon carbide rods, silicon molybdenum rods, and electric heating wires as heating sources.
Roller furnaces are mainly used in the production and application of ceramic tiles, powder materials and other industries. Therefore, the heating source is particularly important. More and more customers are improving the quality in the selection of heating wires, and choosing high-quality heating wires, that is, imported heating wires. Although the price of imported heating wire is more expensive than that of domestic heating wire, based on the sales in recent years, more companies are willing to purchase imported heating wire and related products produced by imported heating wire, which are superior in product performance. Domestically produced is affirmative.
Imported heating wire products are made of advanced stainless steel and special alloys produced in the most demanding environment, so it has a wider range of applications and can meet higher requirements. The heating wire products imported on the market mainly include: Kanthal KANTHAL heating wire from Sweden, Isabellenhuette from Germany (currently the most advanced manufacturer of precision micro-resistance resistors in the world), and Sedes electrothermal alloy from the United States (saides) Des Sedes is a brand, the world’s leading developer and manufacturer of industrial heating). Among these professional manufacturers, Kanthal KANTHAL heating wire from Sweden is particularly cost-effective and has a considerable share in the import market. High. What are the advantages of imported heating wire compared with domestic heating wire:
1. The energy conversion efficiency of KANTHAL heating wire is higher than domestic heating wire, the highest 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 wire.
3. KANTHAL heating wire has a high surface load.
4. KANTHAL heating wire has high resistivity.
5. KANTHAL heating wire has lower density and saves material cost.
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 furnace, the electric furnace wire made of Kanthal consumes less materials and has a longer life.
Customers must reasonably choose the products they need according to their own equipment needs, so that they can be value for money. Electric heating wire has a wide range of uses. The quality of heating wire products has a direct relationship with the manufacturer. Care must be taken in product selection.
