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.
