Pusher Furnace

Pusher Furnace manufactured by United Enterprises is a continuous-type heat treatment furnace where charge trays advance through the heating chamber by a controlled pusher mechanism, ideal for steady, repeatable processing of bulk components.

Brief Description:

The pusher furnace is a workhorse in industrial heat treatment well suited for annealing, hardening, normalizing and sintering of small to medium-sized parts. Its simple, rugged design and the ability to maintain stable temperature profiles make it a preferred choice for high-volume production.

We supply pusher furnaces in both controlled atmosphere and air-atmosphere versions. Atmosphere control is achieved using our in-house Ammonia Cracker, Endo Gas Generator or Nitrogen Generator. Multi-zone temperature control ensures uniform heating across the load.

Each furnace is tailored to the customers production rate, tray size, component weight and target temperature.

Characteristics:

• Continuous pusher movement for stable production cycle
• Maximum temperature up to 1200C
• Available in electrical or recuperative gas-fired heating
• Atmosphere control with in-house gas generators
• Multi-zone PLC control for accurate ramp/soak
• Heavy-duty refractory lining for extended life
• Automatic discharge and tray return system (optional)
• SCADA-based recipe storage and data logging

FAQs:

Q: What is the difference between a pusher furnace and a roller hearth furnace?

A: In a pusher furnace, charge trays are pushed forward; in a roller hearth furnace, the load is conveyed by powered rollers. Pusher furnaces are typically more economical for high-volume tray-based heat treatment, while roller hearths suit longer or asymmetric parts.

Q: Can I retrofit atmosphere control later?

A: Yes. If specified early on, the furnace can be built atmosphere-ready, allowing a controlled-atmosphere upgrade with sealing, gas train and an ammonia cracker added at a later stage.

Q: What warranty do you provide?

A: Standard warranty covers manufacturing defects on key mechanical and electrical components. Detailed warranty terms are shared at the time of quotation.
