Pusher Furnace

Home / Our Products / Furnaces / Pusher Furnace

A Pusher Furnace is a type of continuous heat treatment furnace designed for high-volume production. It uses a pusher mechanism to move trays, baskets, or workpieces through different temperature zones in a controlled and consistent manner. These furnaces operate in gas-fired, oil-fired, or electrically heated configurations and are widely used in metallurgical, automotive, aerospace, and manufacturing industries.

How a Pusher Furnace Works

Loading - Workpieces or trays are loaded at the furnace entrance.
Pushing Mechanism - A mechanical or hydraulic pusher moves the material through different heating zones.
Heating Zones - The furnace has multiple temperature zones for precise heat treatment.
Cooling Zone - After processing, the material enters a controlled cooling or quenching chamber.
Unloading - Treated parts exit the furnace automatically for further processing or storage.

Key Features of Pusher Furnaces

Continuous & Automated Operation - High productivity with minimal manual handling.
Uniform Temperature Distribution - Ensures consistent mechanical properties.
Customizable Heating Zones - Tailored temperature control for different materials.
Controlled Atmosphere Options - Prevents oxidation and improves surface finish.
Energy-Efficient Design - Advanced insulation and heat recovery systems.
Durable & Robust Construction - Designed for high-temperature and heavy-duty applications.

Applications of Pusher Furnaces

Metal Heat Treatment - Annealing, hardening, tempering, and stress relieving.
Powder Metallurgy & Sintering - Processing metal powders, carbide parts, and ceramics.
Automotive & Aerospace Parts - Gears, shafts, bearings, and structural components.
Forging & Steel Industry - Preheating billets and bars before rolling or forging.
Electronics & Semiconductor - Brazing and sintering of electronic components.
