Process

The continuous process of hardening and tempering bimetal saw bands

Bimetal saw bands are composed of two different materials: The backing material and the cutting material.
While the backing material should have a high flexibility, the cutting material must be hard and wear-resistant.

When hardening and tempering saw bands, these different properties are achieved by the following process steps:

  • Hardening:
    Heating and soaking the saw band to hardening temperature in the hardening furnace and subsequent quenching in the cooling section
  • Tempering:  
    Multiple heating and soaking to tempering temperature in the tempering furnace and subsequent cooling in cooling sections
Plant Engineering

ALO 198-ILT hardening and tempering furnace plants

Our partner ALO Center AB from Sweden sells continuous hardening and tempering furnace plants with hardening and tempering furnaces from ONEJOON.

Due to the modular plant concept we design the plant according to your requirements:

  • plant components individually selectable
  • energy-efficient multiple tempering in tempering furnaces
  • variable furnace lengths
  • compact design through induction preheating and short cooling zones
  • two saw bands per plant possible
  • gentle turning of the band enables special layouts

  • Test 5

    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 
  • 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.
