Proven continuous technology for maximum output and precision
AFC-Holcroft pusher furnaces combine robust engineering with advanced atmosphere management to deliver high production rates and precise metallurgical control. Their modular multi-chamber design ensures independent zone regulation and easy service access. Built using standard building-block components, each system is custom-designed to fit available space and production needs while maintaining industry-leading uptime and process stability.
Additional technical features
Single to six-row layouts with straight-through or side-entry arrangements.
Modular multi-chamber construction for precise temperature and atmosphere control.
Tray-hearth skid rails made from silicon carbide or high-alumina materials; segmented for easy replacement.
Exclusive “Alligator” door system for automatic resealing and safe pressure relief.
Captive-chain tray transfer mechanism (horizontal or vertical) in sealed housing for longer life and reduced floor space requirements.
Main pusher mechanism with recirculating ball nut and screw, automatically retracts under jam or overload conditions.
Atmosphere circulation systems: roof or sidewall fans, including patented dual-flow design for uniform heat and carbon potential.
Heating system options: single-ended and U-type radiant tubes (fossil fuel or electric), internal/external recuperators reduce fuel use by up to 30 %
Quench systems: agitation via propeller or submerged pump for dense loads in oil, water, polymer or salt media
CFD (computational fluid dynamics) modeling used for design optimization, fixture analysis and process simulation
