1700°C High-Temperature, Fully Automatic, Internal-Circulation Electric Push-Plate Kiln with Opposing Dual Ports

1700°C High-Temperature, Fully Automatic, Dual-Channel Counter-Flow Pusher-Plate Electric Kiln

This 1700°C high-temperature, fully automatic, dual-channel counter-flow electric Push-Plate kiln is designed for the continuous sintering of alumina ceramics, electronic ceramics, structural ceramics, advanced ceramics, and high-performance inorganic materials. Featuring an innovative dual-channel counter-flow structure, a fully automatic hydraulic pushing system, and intelligent digital temperature control technology, the equipment delivers high productivity, low energy consumption, excellent temperature uniformity, and long-term stable operation.

The kiln has a maximum design temperature of 1730°C and a continuous operating temperature of 1680°C. It utilizes an independent dual-channel operating mode, allowing it to simultaneously meet the sintering requirements of different ceramic products. Through dual-channel waste heat recovery technology, thermal energy utilization is significantly enhanced—achieving energy savings of over 35% compared to traditional single-channel pusher-plate kilns—making it an ideal solution for the continuous production of modern advanced ceramics.

1. Modular Structure with Dual Opposing Channels

The furnace features two parallel channels arranged in an opposing dual-bore configuration, doubling the production capacity compared to single-bore kilns. Fully automated internal circulation reduces labor intensity and effectively boosts production efficiency. Independent temperature control for the two channels allows Channels A and B to be configured separately for sintering 95-grade and 99-grade ceramics, offering process flexibility.

2. Uniform and Stable Temperature

Thanks to a unique structural design and optimized control and power distribution strategies, the furnace achieves optimal temperature stability and uniformity within ±5°C. Temperature stability is maintained at ±1°C/h. The system utilizes 8 heating zones and 8-point temperature control; this multi-zone, multi-point control minimizes the formation of closed pores, significantly enhancing the sintering quality of the products.

3. Fully Automated Internal Circulation and Advanced Pusher System

The equipment utilizes a hydraulic pusher system featuring a “fast-advance/slow-retract” mechanism; the slow-retract time is only 10 seconds, preventing temperature fluctuations caused by the pusher’s movement. It delivers a main thrust of 8–10 tons, with a continuously adjustable pushing speed ranging from 200 to 800 mm/h (standard operating speed: 300 mm/h). The propulsion assembly consists of one main pusher and three auxiliary pushers.

4. Optimized High-Temperature Structure and Long Kiln Lifespan

The furnace chamber features a dual-channel structure supported by a central pillar, with heating elements arranged on the left, center, and right sides. High-purity, low-silicon corundum is used for the high-temperature zone of the chamber, while machine-pressed, sintered 99-grade wear-resistant corundum is used for the slide rails.

5. Comprehensive Exhaust and Venting System

The furnace chamber is designed with dedicated roof vents to exhaust high-temperature, contaminated gases. Exhaust stacks are located at the kiln entrance, with two stacks serving each channel.
