High Temp Alloy Wire Heating Rod for Heat Treatment quenching Furnace

This alloy wire heating rod is developed for harsh high-temperature heat treatment environments that ceramic heating rods cannot withstand. It adopts imported FeCrAl or nickel-chromium alloy resistance wire as the core heating medium, featuring excellent high-temperature strength, anti-carburization and thermal shock resistance.

Different from ceramic heating rods used for medium-low temperature tempering lines, this alloy heating rod can stably operate at ultra-high temperature up to 1250℃ for a long time. It is widely matched with box quenching furnaces, bogie hearth high-temperature sintering furnaces and carburizing furnaces, perfectly meeting the rapid heating and high holding temperature requirements of mold steel, high-hardness fasteners and powder metallurgy structural parts.

After power on, the internal FeCrAl/NiCr alloy wire generates heat rapidly and radiates uniform infrared heat into the closed furnace cavity. The high-temperature alloy structure maintains stable resistance value under long-term ultra-high temperature environment, providing continuous and stable heat source for quenching, sintering and carburizing processes. Its anti-carburizing property prevents carbon powder from corroding the heating core, extending service life under harsh furnace atmosphere.

Q1: When should I choose alloy wire heating rod instead of ceramic heating rod?

A: Select alloy wire heating rod if your furnace working temperature exceeds 900℃, or the equipment runs under carburizing/quenching harsh atmosphere; ceramic rods are only suitable for medium-low temperature tempering lines below 900℃.

Q2: Will the alloy wire break easily under frequent quenching temperature cycles?

A: Our alloy wire is high-temperature forged with optimized winding process, with strong thermal shock resistance, no fracture failure after thousands of heating-cooling cycles.
