One of the recent outstanding developments in the heat treating field has been the application of induction heating to localized surface hardening. The advances made contingent with the application of high frequency current have been nothing short of phenomenal. Starting a comparatively short time ago as a long-sought-after method of hardening bearing surfaces on crankshafts … Read more
Induction bending pipe What is Induction Bending? Induction Bending is a precisely controlled and efficient piping bending technique. Local heating using high frequency induced electrical power is applied during the induction bending process. Pipes, tubes, and even structural shapes (channels, W & H sections) can be bent efficiently in an induction bending machine. Induction bending … Read more
Induction Hot Forming Steel Pipe Objective : To heat a magnetic steel pipe to the targeted temperature to enable pipe induction bending; the objective is to create u-bends in pipes for boiler systems Material: Steel pipes (2.5”/64 mm OD bent steel pipe) Temperature: 2010 °F (1099 °C) Frequency: 8.8 kHz Equipment : DW-MF-250 kW, 5-15 … Read more
Induction Hardening and tempering Surface Process Induction Hardening Induction Hardening is a process of heating followed by cooling generally fast for increase hardness and mechanical strength of steel. To this end, the steel is heated to a temperature slightly higher than the upper critical (between 850-900ºC) and then cooled more or less quickly (depending on … Read more
Induction wire and cable heater is also used for the induction preheating, post heating or annealing of metallic wire along with the bonding/vulcanization of insulating or shielding within various cable products. Preheating applications can include heating wire prior to drawing it down or extruding. Post heating would typically include processes such a bonding, vulcanizing, curing … Read more
What is induction curing? How does induction curing work? Simply put, line power is converted to alternating current and delivered to a work coil which creates an electromagnetic field within the coil. The piece with the epoxy on it can be metal or a semiconductor such as carbon or graphite. To cure epoxy on non-conductive substrates … Read more
Induction Wire Heating Process Applications In the production of steel wire, copper wire, brass wire, and steel or heating copper spring rods, different heat treatment processes are used, such as wire drawing, tempering after production, quenching heat treatment in special requirements, induction annealing before use as raw material, etc. There are a lot of requests … Read more
induction preheating copper bars to temperature Objective: To preheat two copper bars to temperature within 30 seconds; the client is looking to replace a competitor’s 5kW induction heating system that is delivering unsatisfactory results Material: Copper bars (1.25” x 0.375” x 3.5”/31mm x 10mm x 89mm ) – Thermal indicating paint Temperature: 750 ºF (399 … Read more
The kinetics of induction heating for surface quenching of steel The kinetics of induction heating for surface quenching of steel depend on factors: 1) which induce changes in the electric and magnetic parameters of steels as the result of the increased temperature (these changes lead to changes in the amount of absorbed heat at a … Read more
