Furnace Types

Fluidbed Furnaces

Used for:
Annealing, Tempering, Stress Relieving, Patenting,

Quenching Lead Furnaces

Used for:
Annealing, Tempering, Quenching, Patenting,

Muffle or Tube Furnaces

The Muffle or Tube Furnaces are built for the continuous in-line austenitizing or annealing of multiple wire strands. High velocity burners are mounted along both sides of the furnaces in a staggered pattern that produces excellent temperature uniformity. Pressure controled combustion available on some furnaces gives a high turn-down ratio and efficient multiple burner control.

Direct Fired Muffle and Tube Furnaces

Direct Fired Furnaces like the Muffle or Tube Furnaces are built for the continuous in-line austenitizing or annealing of multiple wire strands. High velocity burners are normally mounted along both sides of the furnaces in a staggered pattern in order to produce temperature uniformity. Generally used for: Austenitizing stainless steel wire

Annealing Oil Tempering Lines

Oil Tempering Lines consist of an Austenitizing Furnace, Quenching System, Tempering Furnace and Cooling and Coating Tanks. The Austenitizing Furnace can be Direct Fired, Fluidbed or Muffle Tube for atmosphere control. Following the heating section, the wires are rapidly quenched in a cooling medium of mineral based oil or water based polymer fluids.

Bell Furnaces

Bell furnace processing provides better control of the cooling process and also allows for a slower cooling period where the temperature can be held at a fixed intermediate temprature for an extended period. Bell Furnaces also allow for a more homogeneous and faster heat transfer.

Salt bath furnaces

Salt bath furnaces are used for a number of heat treatment applications such as: Preheating • Austenitizing • Martempering • Neutral Hardening • High-Speed Tool Hardening • Tempering Nitriding • Carburizing • Solution Heat Treating • Dip Brazing Modern systems offer quick ramp-up and high heating uniformity
