New Generation of Induction Heating Machines for the Forging/Rolling Industry

Authors: Valery Rudnev, Don L. Loveless, KS, Mike S. Rugg
Publication: Proc. of 20th ASM Heat Treating Conference, St. Louis, October, 2000
Date: 10/1/2000

The core of this presentation combines materials previously published by authors in several different magazines. Analysis of the most important factors involved in making decision on designing or purchasing a particular induction slab/plate/billet/bar re-heating machines. Articles discusses some imperative features of a new generation of induction heating machines for the forging/rolling industry.

Efficiency and Temperature Considerations in Induction Re-Heating of Bar, Rod and Slab

Authors: Valery Rudnev, Don L. Loveless, KS, Peter R. Dickson, Mike S. Rugg
Publication: Industrial Heating
Date: 6/1/2000

Article discusses different aspects of induction re-heating of bars, slabs, blooms and rods in continuous casting lines including: 'surface-to-core' temperature profile use of computer modeling 'nose-to-tail' temperature profiles bars/slabs with rectangular and trapezoidal cross sections energy efficiency and cost solid state power supplies case studies

Want Your Bar at Uniform Temperature?

Authors: Valery Rudnev, Don L. Loveless, Walter B. Albert, KS, Peter R. Dickson
Publication: Forging Magazine
Date: 6/1/1999

When designing modern in-line induction heating systems, a requirement for temperature uniformity of the re-heated product is only one of the goals. Additional design criteria include maximum production rate, minimum metal losses (due to scale, oxidation, burns, decarburization, etc.) and providing compact systems that have a high electrical efficiency. Other important factors include quality assurance, enValery I. Rudnevonmental friendliness, automation capability, reliability and maintainability of the equipment. The last criteria, but not the least, is the competitive cost of an induction heating system. This article will discuss ways to optimize some of the above described criteria.

Semi-Solid Processing of Aluminum Alloys

Authors: S. Midson, Valery I. Rudnev, R. Gallik
Publication: Proceedings of the 5th International Conference on the Processing of Semi-Solid Alloys and Composites
Date: 7/1/1998

This article describes the state-of-the-art in developing commercial induction heating systems for semi-solid metal forming. Some subtle aspects of induction slug heating, including end and edge effects are discussed. Understanding the nature of these effects (such as non-uniform temperature distribution, 'slug tilting', 'elephant foot' phenomena and 'surface erosion' at the top of a slug) are imperative for induction heating practitioners and engineers in order to provide quality semi-solid formed products.

Fundamentals of Specifying Induction Power Supplies for Wire and Rod Heating

Authors: GJT, Dan J. Williams
Publication: Wire Journal
Date: 6/1/1997

A no-nonsense recap of the wire heating industry and alternative heating techniques. The focus on emerging electromagnetic induction heating methods enables readers to better understand and specify induction equipment for wire heating applications.

Induction Billet Heaters Engineered for Isothermal Extrusion

Authors: Valery Rudnev, D.L. Mellon
Publication: Modern Metals
Date: 9/1/1995

This article discusses a step from building a conventional, single-temperature induction heater for aluminium extrusion billets to one customized to produce a controlled temperature gradient for isothermal extrusion. 'Inverse Design' process tailors induction coils for specific temperature gradients.
