High-Precision Tempering Furnace – Up to 1200°C | Customizable & Factory-Ready
As a process engineer at Jiuying, I’ve helped dozens of factories improve their heat treatment consistency. Our Tempering Furnace isn’t just another box oven – it’s engineered for reliability, precise thermal profiles, and around-the-clock production. Whether you temper alloy steels, anneal glass, or perform research sintering, this furnace delivers repeatable results day after day.
How This Tempering Furnace Works (Working Principle)
Unlike conventional ovens that rely on simple on/off thermostats, our Tempering Furnace uses a PID + SCR closed-loop control system. A K-type thermocouple continuously monitors chamber temperature (accuracy ±1°C), sending signals to the silicon controlled rectifier (SCR) which adjusts power output smoothly – no jarring relay clicks. The programmable controller supports 50 segments for heating rate, cooling rate, and dwell time. This means your parts experience exactly the tempering cycle you specify, from ramp-up to soak to controlled cooling, eliminating residual stresses and improving metallurgical properties.
Performance Features That Set Our Tempering Furnace Apart
Exceptional Thermal Uniformity: Double-layer ceramic fiber insulation (1430°C + 1260°C grade) and balanced heating element placement keep gradients minimal – crucial for tempering precision components.
Fast yet Controlled Ramp Rates: 0-20°C/min adjustable heating rate, with recommended cooling ≤10°C/min to prevent thermal shock.
Built-in Safety Intelligence: Over-temperature protection, broken thermocouple detection, and automatic power cut-off when the door opens – safe for unattended operation (alarm included).
Low Shell Temperature: Dual cooling fans + double steel casing ensure the exterior stays below 60°C, reducing energy loss and protecting operators.
Product Details – No Corners Cut
Let me walk you through the engineering details we’ve refined over 8+ years. The heating elements are high-quality resistance wire (Fe-Cr-Al alloy), shaped to avoid sagging at 1200°C. The refractory door block must be inserted before closing – a small habit that extends liner life. Even the thermocouple is replaceable, and we offer optional items like an alumina crucible, gas vent, observation hole, and touch screen interface. Every unit includes a pair of high-temperature gloves and a crucible clip.
One nuance: small surface cracks may appear on the refractory ceramics after extended high-temp use. This is normal and can be repaired with alumina coating – we include repair guidelines in every manual.

How It Differs from Conventional Muffle or Box Furnaces
A standard muffle furnace often lacks programmable cooling or precise SCR control – many still use mechanical relays that shorten element life. Our Tempering Furnace uses phase angle fired SCR and a current limiting resistor, delivering smooth, silent heating without thermal spikes. Additionally, the dual ceramic fiber insulation gives faster heat-up and 20% energy savings compared to brick-lined furnaces. And the explicit cooling rate limitation (≤10°C/min) helps users avoid damaging treated parts – a detail most competitor manuals ignore.
About Jiuying – Your Heat Treatment Partner
Jiuying (short for Jiuying Industrial Equipment) has been designing laboratory and industrial furnaces since 2015. Our factory is ISO 9001:2021 certified, and every Tempering Furnace undergoes a 48-hour burn-in test before shipping. We ship to over 35 countries, supporting local distributors with spare parts. But more importantly, we treat every customer as a long-term partner. Got a tricky application? Our engineers will recommend pre-sales modifications – like adding a gas vent for debinding or an observation hole for in-situ monitoring.
Frequently Asked Questions (FAQ) About Our Tempering Furnace
A: Yes, typical tempering range for HSS is 540-600°C, well within 1100°C working range. The 50-segment program lets you do multi-step tempering cycles.
A: Exceeding 10°C/min may cause thermal stress on the lining and your parts. Our PID cooling program can be set to follow a descending ramp for controlled cooling.
A: Yes – it’s an optional spare. The touch screen allows recipe management, real-time graphing, and data logging via USB.
A: Absolutely. For any order, you can choose from RAL color palettes and we’ll add your company logo on the nameplate – at no extra cost for standard customization.
A: Toxic or explosive gases are NOT recommended without external ventilation and safety control. For safe binder burnout, please add the gas vent option and consult our safety team.
