The best plants for continuous hardening and tempering of bimetal saw bands

Sturdy design

• different coiling plate diameters up to 1.200 mm available
• can be used with ALO 9091x expandable coiling centres
• coiling plates can be swivelled for coil change

For continuous operation during hardening and tempering

This system includes a band welding fixture and a pneumatic shear to trim the band ends before welding.

• band width: 20 - 80 mm
• band thickness: 0.9 - 1.6 mm

For continuous hardening and tempering

for feeding the furnace plant with band while changing coil and welding 

• loop capacity 12 m 
• band width 20 - 80 mm 
• band thickness 0.9 - 1.6 mm 

Strong and sturdy

for pulling the saw band through the furnace plant and for generating band tension.

• band width 20 - 80 mm 
• band thickness 0.9 - 1.6 mm 
• drive systemservo motor and gear 

With high efficiency rate

saves furnace length by heating up the saw band quickly. 

• band width 20 – 85 mm 
• band thickness 0.6 - 1.6 mm 
• heating capacity up to 750 °C 
• heating capacity 600 °C (for 27 x 0,9mm at 5m/min)
• power consumption max. 14 kVA

With excellent insulation

for heating and soaking the saw band at hardening temperature

• nominal temperature approx. 1,230 °C 
• electrically heated 
• 6 heating zones 
• standard sizes (heated length/heating capacity per muffle)
  5.1 m/60 kW
  6.0 m/70 kW 
  6.8 m/80 kW
  other sizes on request 
• with 1 or 2 high-temperature resistant furnace muffles 
• protective gas atmosphere in the process area 
• modular construction, variable length 
• standardised components and assembly groups

Compact and efficient

The quenching of the hot saw band is carried out by a large volume flow of cold protective gas which flows around the blade. The heated gas is effectively cooled down again in a gas/water heat exchanger and then reused.

• band width 20 – 80 mm 
• band thickness 0.9 - 1.6 mm 
• quench effect 15-30 kW 
• power consumption average 3.5 kVA, max. 9 kVA 

With excellent insulation

for heating and keeping the saw band at tempering temperature

• nominal temperature approx. 750 °C 
• heated electrically 
• 4 heating zones per muffle
  standard sizes (heated length/heating capacity per muffle)
  4.7 m/12 kW
  6.3 m/16 kW
  other sizes on request 
• with 1 to 3 furnace muffles 
• protective gas atmosphere in the process area 
• modular construction, variable length 
• standardised components and assemblies
