Flame Hardening

Flame Hardening

Why Flame Hardening Will Save You Money

Flame hardening is a reliable and time-proven alternative to other types of heat treatment and the savings can be tremendous.

Flame hardening will save you money and help increase profits, because it…

  • gives higher hardness for increased life
  • provides more efficient productivity
  • reduces downtime and maintenance costs
  • hardens selected areas only
  • reduces costs because of less coverage
    • less distortion
    • less machining and grinding, and
    • less processing time

Rolls and Shafts

Flame hardening is the best and sometimes the only way to heat treat large rolls.

  • Minimum distortion and higher surface hardness is combined with ductilitiy and core strength.
  • The ‘progressive spin’ method ensures a uniform hardness over the entire roll surface.
  • We can flame harden rolls up to 1000mm in diameter.

Sheaves, Rope Drums and Slew Rings

Flame hardening dramatically reduces wear on load bearing rope groove areas and bearing surfaces on slew rings and thrust bearings.

We Can Perform Full or Partial Groove Area Hardening.

Machine Ways and Rails

Today’s modern flexible machining systems and automated transfer lines have many flame hardened components, including

  • Replaceable Ways
  • Fabricated Basesmachine Ways and Rails
  • Precision Guide Rails
  • Cast Beds and Pallets

Whatever your needs, we have the experience to process these parts for optimum results.

Dies and Moulds

Flame hardening of dies and moulds reduces wear and increases die life.

Large automotive dies provide ideal examples of the proper application of flame hardening and can be handled as readily as small ones.

Smaller dies may require hardening of shut-off or runner areas only. Instead of buying new dies, flame hardening allows the reworking of old dies by making shape modifications and re-flame hardening.

Dies can be finished and tried out before they are finally flame hardened for production runs.

The flame hardened areas are usually adjacent to the die working faces so there is a minimum of heat exposure which eliminates distortion.

Applications

  • Plastic mould dies
  • Metal stamping, blanking, forming and shearing dies

Suitable materials

  • Alloy steels
  • Plain carbon steels
  • Ductile iron
  • Cast iron
  • Stainless steels

Gears and Sprockets

Replacement of worn gears can be expensive, time-consuming and difficult.

Increase the life of gears, sprockets and gear racks with flame hardening.

By only hardening the wear areas of the gears, the base metal keeps its original tensile strength.
