- Status = on foundation, in operation (April 2024)

Data
- Annual production = 50,000 mtons (mixed)
- Furnace charge = 25 mtons max
- Furnace performance per hour = 6-7 mtons/hr of 10“ log

Material
- 6xxx and 7xxx aluminum alloys

Log Size Capacity
- Round = 103mm, 254mm, 280mm, 330mm, & 405mm diameters (4", 10", 11", 13", 16")
- Rectangle = 342mm x 185 mm (13.46" x 7.28")
- Log length = 7000mm min to 7300mm max (22.96 to 23.95 feet)

Furnace
- Design = vertical!. Vertical homogenizing allows any log diameter or shape to be processed continuously without interrupting or changing flow.

- Furnace cross circulation = Air flow transversely to the transport direction

- Log passage = automatic, hanging

- Furnace zones = 3
1. Heating zone = capacity 16 positions
2. Holding zone = capacity 24 positions
3. Cooling zone = capacity 8 positions

- Heating Capacity
1. Work temperature = 565 - 600 °C variable
2. Heat-up time (20 to 550°C) = 3 hours for 10" diam log
3. Temperature tolerance = +/- 2 °C at the Log surface
4. Soak time = 4 hours, variable

- Heat Source and Burners
1. Natural gas (H, cross circulation)
2. Gas heat value = 22,350 Kcal/m3
3. Burner type = Recuperator-high-speed-burner
4. Number of burners = 9
5. Exhaust = 6 x hot-gas certified circulation fans
6. Cooling = 600-300°C in 30 minutes - and - 300-100°C in 60 minutes / cooling air drawn in from plant / cooling air exhaust by 2 radial-flow fans

- Hydraulics
1. Operating medium = hydraulic fluid HFC
2. Q = 140 l/min
3. V = 100 ccm/U
4. p = 140 bar
5. Power P = 30 kW
6. Speed n = 1450 min-1
7. Voltage = 400/690 V
8. Frequency = 50 Hz

- Electrics
1. Main supply = 3x400 V TN-C-S, 50 Hz
2. Control voltage = 24 VDC
3. Fusing = 20 Amps

- Controls
1. Allen Bradly ControlLogix
2. Operator Panel PV Plus 1500 Allen-Bradley
3. Cabinet 1 = +AE1 = part movements, log cooling, main disconnect switch = 340V
4. Cabinet 2 = +AE2 = part movements, furnace top, main disconnect switch = 330V
5. Cabinet 3 = +AE3 = part furnace heating at the Furnace Top, main disconnect switch = 490V

- Furnace dimensions (total footprint including cooling chamber)
- Length = approx. 30,300mm (99.5 ft)
- Width = approx. 3,400mm (11.1 ft)
- Height = approx. 11,000mm (36.1 ft)
