PBHF-1250-A 1250 kg/h Gas-Fired Piece Billet Heating Furnace
- Brand: OEM FURNACE
- Product Code: PBHF-1250-A
PBHF-1250-A is a continuous gas-fired furnace that heats short (piece) billets for aluminium extrusion presses. With Ø178×480 mm billets it brings 1250 kg of aluminium per hour to about 500 °C. Billets travel through the furnace in a single row, end to end, on rollers; at each cycle one cold billet goes in and one hot billet comes out.
Material flow
Billets are taken one by one from a zig-zag rack basket brought by forklift, drop into a V-trough and are pushed into the furnace by a hydraulic pusher. The furnace starts with an entry tunnel heated by flue gas and 4 preheating modules (double-walled, with circulation fans), followed by 6 heating zones. At the exit a pneumatic door opens and the billet is taken by a jaw gripper to the exit table.
Heating
In the heating zones premix gas nozzles face each other on both sides of the billet; for the large billet diameter there are two rows of nozzles on each side, with the billet axis between them, set in shaped refractory bricks around it. Each zone has its own combustion group, pilot burner, flame control and temperature limiter; billet temperature is measured in every zone by a pneumatic thermocouple lance. Hot flue gas passes through the preheating section before the stack, so incoming billets are preheated with this heat.
Rollers and body
Rollers are Ø145 mm twin-disc V-cradles; AISI 310 stainless steel in the heating section and AISI 304 in preheating. Roller bearings sit outside the body, away from the heat. The heating section roof has 250 mm multi-layer insulation and can be lifted for maintenance.
Control
The line is run from a PLC / operator panel in the electrical cabinet; circulation and flue fans are frequency-controlled (5 drives). Pusher, door, thermocouple and exit gripper are pneumatic and hydraulic.

PBHF family
The family stays single-row and grows with billet diameter and furnace length; rollers, nozzles, combustion group and pusher are common to all models, and the billet basket is scaled to billet diameter. For billets above Ø130 mm (PBHF-800 to PBHF-2500) the body section is widened, nozzles are in two rows on each side and heating is split into 4–6 zones.
