China Factory Large Capacity Box Tempering Furnace for Industrial Mass Production Tempering

The box type tempering furnace is a batch-type electric heat treatment furnace professionally engineered for tempering treatment and residual stress relief on all kinds of metal parts and alloy steel components. Operating under standard atmospheric conditions, this industrial tempering oven comes with dual control modes: manual operation and fully automatic intelligent temperature regulation. It fully meets varied heat treatment standards for steel molds, transmission gears, tool steel, stainless steel blanks and conventional metal hardware components.

Unlike continuous processing furnaces, our electric box tempering furnace delivers flexible batch production capability, consistent internal temperature uniformity and lower daily running expenses. It serves as a cost-effective, energy-efficient heat treatment option for small-batch, high-precision industrial tempering workflows. This furnace model is widely deployed across hardware fabrication, machinery component machining, automotive spare parts manufacturing and precision mold production sectors worldwide.

1.Excellent Temperature Uniformity: Equipped with circulating air cooling fan system and multi-point heating layout, the furnace achieves temperature uniformity within ±5℃, ensuring consistent tempering quality for every batch of workpieces.

2.Intelligent Programmable Control: Adopts touchscreen PLC control system with heat preservation timing, over-temperature alarm and automatic protection functions, effectively avoiding temperature deviation and workpiece processing defects.

3.Durable & Easy Maintenance Structure: Removable integral furnace chamber and detachable spiral heating wires greatly reduce daily maintenance difficulty and later maintenance cost.

4.Stable & Energy-Saving Performance: High-temperature resistant wire heating elements and optimized air circulation design lower power consumption while maintaining stable long-term operation.

5.Tight Sealing & Even Heat Circulation: Swing-type furnace door with tight fitting structure ensures balanced internal air circulation, preventing local overheating or uneven tempering effect.

1. Robust & Removable Furnace Wall Structure

The outer furnace wall is welded with high-quality Q235 steel plates for solid structural stability and anti-deformation performance. The inner lining adopts 3mm pressed perforated stainless steel plate, featuring high temperature resistance and oxidation resistance. The integral furnace chamber is removable, allowing overall disassembly and convenient daily inspection and maintenance, greatly improving equipment service life.

2. Precise Intelligent Temperature Control System

This programmable box tempering furnace is equipped with professional power controller and full Delixi Electric supporting components, ensuring stable and sensitive control performance. It supports multiple practical functions including constant temperature heat preservation timing and automatic over-temperature alarm protection. The high-precision touchscreen control panel and 6-point digital temperature probe meter realize real-time temperature monitoring, effectively eliminate temperature fluctuation, and ensure uniform heating inside the furnace chamber.

3. Tight Swing-Type Furnace Door Design

Adopts left-right swing opening door structure with high-precision fitting design. The furnace door closely fits the furnace body surface after closing, effectively reducing heat loss and ensuring uniform internal air circulation. It avoids local temperature difference caused by air leakage, guaranteeing stable and consistent tempering effect for all workpieces.

4. High-Power Stainless Steel Air Circulation Fan

Equipped with high-efficiency air-cooled centrifugal exhaust fan to strengthen internal hot air convection and realize full-chamber uniform temperature distribution. The fan adopts extended shaft structure; both impeller and shaft are made of premium 304S stainless steel. With 4mm impeller thickness and 550mm diameter, the fan features high temperature resistance, corrosion resistance, stable operation and long service life.

5. Full-Range Multi-Side Heating Layout

The heating components adopt layered spiral high-resistance heating wires, arranged on the top, bottom, left, right and furnace door positions in all directions. The full coverage heating design realizes 360° uniform heating without dead angle. Meanwhile, the detachable heating wire structure simplifies replacement and maintenance procedures, reducing equipment downtime and maintenance cost.
