Pusher Furnace

High-Efficiency Pusher Furnace– Continuous Heat Treatment for Large-Volume Industrial Production

Keywords: Continuous Pusher Furnace, Pusher Type Kiln, Sintering Pusher Furnace, Industrial Pusher Kiln

Product Details

2. Product Overview

Our Continuous Pusher Furnaces (Pusher Kilns) are engineered for high-precision, large-scale thermal processing. By utilizing a synchronized mechanical or hydraulic pusher system, workpieces in saggars or trays are transported through precisely controlled heating and cooling zones. This equipment is the industry benchmark for sintering, calcining, and annealing in sectors where consistency, reliability, and high throughput are non-negotiable.

3. Key Features & Benefits

  • Exceptional Process Stability: The continuous “train” of product trays ensures that every workpiece experiences an identical temperature-time profile, delivering unmatched batch-to-batch consistency.

  • Heavy-Duty Loading: Designed to handle high-density loads, our pusher systems are built for robust performance under heavy saggar weights without compromising precision.

  • Advanced Atmosphere Control: Features vacuum-tight or atmosphere-controlled chambers for Nitrogen, Hydrogen, or Air, with precision gas curtains at the entrance and exit.

  • Multi-Zone Temperature Precision: Independent heating zones with PID control allow for complex thermal profiles, including dewaxing, pre-heating, sintering, and cooling.

  • Low Operating Costs: High-quality refractory lining and energy-saving heating elements minimize heat loss, significantly lowering the energy cost per unit.

  • Automated Return System (Optional): Can be equipped with an automated tray return conveyor for a fully closed-loop, labor-saving production cycle.

5. Typical Applications

The Pusher Kiln is the standard for high-volume manufacturing of:

  • Powder Metallurgy: Sintering of iron, copper, and stainless steel parts.

  • Electronic Ceramics: Processing of MLCCs, ferrites, and piezoelectric components.

  • Battery Materials: Calcination of cathode and anode materials for lithium-ion batteries.

  • Magnetic Materials: High-temperature annealing of soft and hard magnetic alloys.

  • Technical Ceramics: Sintering of alumina, zirconia, and silicon carbide parts.

6. Why Choose Our Pusher Furnaces?

  • Precision Engineering: Our pusher mechanisms are designed for ultra-smooth movement, eliminating vibration and tray “shingling.”

  • Custom Muffle & Hearth: We offer specialized silicon carbide or alloy muffles to suit your specific gas-tight requirements.

  • Smart Factory Ready: Fully integrated PLC systems with Ethernet connectivity for real-time data monitoring and remote diagnostics.

7. FAQ

Q: What is the main advantage of a Pusher Furnace over a Mesh Belt Furnace?

A: Pusher Furnaces can handle much higher temperatures and heavier loads. While mesh belts are limited by their tensile strength at high heat, the pusher system moves heavy trays on a solid hearth, allowing for temperatures up to 1700°C and very dense loading.

Q: How do you ensure the trays move smoothly?

A: We use precision-ground hearth plates and guide rails. Our pusher units are equipped with pressure sensors and variable speed controls to ensure a smooth, constant force, preventing any damage to the trays or products.
