1200°C Car-Bottom Furnace with Motorized Platform & Air Circulation

Precision Heat Treatment with Uniformity & Automation

The AJ-STCY Series high-temperature car-bottom furnace is engineered for industrial-grade sintering, annealing, and thermal processing tasks requiring excellent temperature uniformity and large loading capacity. With a continuous working temperature up to 1200°C. A high-efficiency hot air circulation system is integrated at the top of the furnace chamber, equipped with a 0.75 kW circulation motor and a 10.5-inch centrifugal fan made of 310S stainless steel. The fan speed is steplessly adjustable via a frequency inverter, and can be controlled in synchronization with the temperature curve through a PLC system, significantly improving temperature uniformity.

A motorized loading platform ensures smooth, controlled entry and exit of heavy components, while the high-purity alumina fiber lining provides superior insulation, energy savings, and thermal stability.

Core Features & Advantages

Hot Air Circulation System: Integrated airflow mixing enhances furnace temperature uniformity, ensuring consistent heating for all surfaces of the workpiece — ideal for precision sintering and thermal aging.
Motorized Loading Platform: The car-bottom design includes a mechanical drive system with limit switches for precise in/out movement of components up to 1000 kg.
Energy Efficient Insulation: The triple-layer insulation structure with high-purity alumina fiber significantly reduces heat loss and improves safety, reducing energy consumption by over 60% compared to traditional electric furnaces.
High Load, Large Space: Chamber dimensions of 1000×500×500 mm accommodate bulky or batch items, making it suitable for ceramics, refractory parts, and alloy molds.
Smart Temperature Programming: Equipped with an intelligent controller supporting up to 50 programmable segments, including ramp/soak, skip, and real-time modification for fully automated heating/cooling cycles.
Sturdy Construction: Powder-coated double-layer shell with guided airflow channels keeps the surface temperature ≤45°C, ensuring operator safety even during continuous high-temp operation.
Advanced Protection System: Integrated modular control system includes soft start, current/voltage limiting, and full protection against phase loss, over-temp, sensor failure, etc.
Clear Status Monitoring: Real-time display of temperature, segment time, output %, voltage, current, and more — ensuring complete process transparency.
