Heating coil or ribbon for melting furnace annealing furnace
Product Name: High-Temperature Heating Strip
Product Description:
The products can be directly processed into winding, Z-shaped, spiral, etc., and widely used in metal smelting, mechanical manufacturing, industrial electric furnaces, small electric furnaces, muffle furnaces, household appliances, transportation and other industries to produce heating elements and resistance components. Our product specifications are complete in advanced technology and guaranteed quality. Welcome new and old customers to order!
The advantages of high temperature heating strip:
Our product has a long service life and high temperature resistance, such as the maximum service temperature of HRE iron-chromium aluminium alloy wire can reach 1400ºCin the atmosphere; the oxidation resistance of the product surface is very good, the AI2O3 film formed after oxidation has a good high resistivity and resistance; and the allowable surface load is large; its specific gravity is smaller than that of nickel-chromium alloy; its resistivity is also higher and the sulfur resistance is better; but Its price is obviously lower than that of nickel-chromium alloy.
