Induction Heat Treatment of Steels

Heat Treatment of Steels Heat treatment of steelHeat Treating is the process of heating and cooling a steel to obtain desired properties.Various types of heat treatment processes are used to change the following properties or conditionsof the steel:-

Induction Heating

Induction heating is generally used to heat the 'work' directly, that is the induced currents flow in the electrically conducting object being heated. However, there is an important and growing series of applications where induction heating is used to heat a vessel or container from which heat is transferred by conduction to a non-metal product.

How Does Induction Annealing Work?

Induction heating applies heat to very specific areas, faster process time, increased production and high efficiency. In this application, both ends of a copper tube are heated to anneal them as soft as possible 1.5" (38.1mm) from each end, as well as retaining full hardness next to the anneals.

Considerations of configurations on induction heating

Mostly the technique of resistance heating is used for the heat treatment of aluminum alloy casting. The resistance heating consumes more electrical power. So we have proposed a method to deal with the aluminum alloy casting, using induction heating (IH) capable of rapid heating. The expectation for the system is to be applied to industry. Therefore, the system used in factories actually, is

Advantages and disadvantages of induction heating

Rapid cooling, the temperature of the heating layer over the temperature of the critical point of steel surface hardening can be achieved. Classification: according to the frequency of the alternating current, the induction heating and heat treatment is divided into

Rapid Induction Heat Treatment of Articles from Plain

A new method of rapid induction heat treatment (RIHT) of articles and semiproducts from plain and low-alloy low-carbon and medium-carbon steels is described. The method ensures a high ductility at a strength at least no lower than the initial one and a high strength at a ductility higher than the initial one. Examples of pipes from steels 15G2 and 20 are used to show the advantages of the RIHT

Tailoring of microstructure and mechanical properties

2011/3/25The evolution of microstructure during local rapid (induction) heat treatment (LRHT) and its effect on the tension and fatigue properties of Ti–6Al–4V with an initial microstructure of fine-grain equiaxed alpha or coarse-grain colony alpha were investigated.

Microstructure and mechanical properties of

2010/2/1Microstructure changes in commercial-purity titanium (CP-Ti) during local rapid (induction) heat treatment (LRHT) and their influence on tensile and fatigue properties were investigated. It was found that some regimes of LRHT increase the tensile strength by ∼40 MPa and the fatigue limit by

Precision Induction Heating for Tube and Pipe

Drill Pipe Heat Treatment Upsetting or Forging Process for Wall Thickening Drill pipe ends are thickened by heating the pipe end to 1100 C (2012 F) before forging. Induction is often used to heat multiple pipes in a single channel coil, or sequentially in a multi

Induction and Synchronization of Estrus

2019/10/18The hormones that are used in estrus induction are estrogen, progesterone, GnRH, prostaglandin, insulin, and anti-prolactin-based treatment. Synchronization can shorten the breeding period to less than 5 days, instead of females being bred over a 21-day period, depending on the treatment regimen.

10 Considerations When Selecting an Induction Heating

Induction heating offers many benefits to manufacturing processes because it is a rapid, energy-efficient, flameless method of heating electrically conductive materials. A typical system involves an induction power supply, workhead with a copper coil and a chiller or cooling system.

Induction Heating

Dual Frequency Gear Induction Hardening Parts Inductor Coils Example: • For instance, a conventional induction heat treatment might use a single frequency of 25kHz for 2.8 seconds. • A dual frequency induction system might use: – 3kHz frequency for 1.8 sec in preheating –

Advanced induction heating system for hot stamping

The development of a rapid uniform heating process for blanks is needed to perform hot stamping processes. To solve the problem of inhomogeneous temperature distribution in conventional induction heating systems, a heating block has been added to an induction system and investigated to determine if it can achieve rapid and uniform blank heating. To characterize the effects of incorporating the


Using an induction heating system, the 8 process is simple, clean, inexpensive, and fast, with bonding oc-9 curring in 3–5 s. Heat generation is isolated to within several 10 micrometers below the steel surface, allowing for a controllable 11 thermal budget that 12

Hardening Of Steel By Heat Treatment

Internal stresses development is a very serious problem in hardening heat treatment, since they often result in distortion, or cracking, or even, premature failure of part in service. If a steel is cooled slowly, the temperature distribution across the section of the part can be regarded to be uniform; thermal and structural volume change then, occur uniformly and simultaneously throughout the

Basics of Induction Heating Technology

Induction's rapid maturity since its discovery has earned it a reputation of cutting edge technology, critical to discovering new processes that are more effective. Today, induction is synonymous with groundbreaking solutions, paving the way to a new paradigm in manufacturing technology.

Induction welding and heat treatment of steel pipes: evolution of crystallographic texture detrimental to toughness

Induction welding and heat treatment of steel pipes: evolution of crystallographic texture detrimental to toughness P. Yan*1,O.E.Gungor2, P. Thibaux2 and H. K. D. H. Bhadeshia1 Steel welding using induction heating to produce pipelines is found to have lower


Pipe mills naturally design pipe chemistries to suit the rapid internal and external mill quench and heat treatment process. Induction bending is practically limited to external water spray cooling (ie from one side only) at relatively slow speeds and therefore cannot achieve the same quench rate as pipe mills.
