Product Overview

Radiant Heating Rod, also named ceramic radiant heating tube, is the core electric heating element for continuous heat treatment furnaces. It is assembled with high-temperature ceramic insulators, Ni-Cr / Fe-Cr-Al heating wire, thermal insulation section and wiring base. Heating wires are evenly arranged through multi-layer ceramic plates to radiate heat uniformly after electrification. It matches Quenching Furnace, Mesh Belt Tempering furnaces and can directly replace original furnace heating parts.

Main Structure

High temp ceramic insulator discs: separate heating wires, insulation & anti-short circuit, withstand 1200℃
Alloy heating wire: 0Cr25Al5 / Cr20Ni80 optional, anti-oxidation & long service life
Thermal insulation section: wrapped by aluminum silicate fiber, cool down wiring end to protect terminals
Mount base: flange / double lug fixing bracket, easy disassembly
Conductive electrode: thick screw rod, stable conduction, anti-burning

Main Advantages

Uniform furnace temperature: evenly arranged heating wires reduce workpiece heat treatment color difference
Long service life: high resistance alloy wire with great anti-oxidation performance for 24h continuous operation
Safe insulation: high-purity alumina ceramic avoids electric leakage and furnace short circuit
Cool wiring end: thick thermal insulation prevents terminal aging and burning
Easy maintenance: integrated assembly, direct whole rod replacement without on-site wire threading
Full customization: length, power, voltage, mounting bracket OEM based on furnace drawings
Atmosphere resistant: stable working under carburizing & nitrogen protective bright annealing atmosphere

FAQ

Q1：Can it work under nitrogen carburizing atmosphere?

A: Yes. Our alloy heating wire has excellent anti-carburization performance, stable running under nitrogen protective atmosphere for bright annealing and carburizing process.

Q2: How long is the service life?

A: Under normal working temperature without overload, service life reaches 8–12 months for 24h continuous production.

Q3: Support drawing customization?

A: Accept customer 2D drawings, adjust total length, power, voltage and mounting base to match your furnace.
