Abstract This study focuses on two major advantages of induction heating over flame heating in the treatment of coated boiler tubes. In both cases the induction heating process is simple, fast and effective. Firstly, we will show how the the use of induction heating results in exceptionally thick and hard coatings with low porosity. Having high corrosion and wear resistant properties, the products can satisfy industry's needs for reliable coatings with a long service life. Next, the study will detail how a pipe with the coating already applied can be simultaneously bent by induction heating while the coating is melted and fused to the pipe. The result is a thicker, more even and reliable coating than that accomplished by the flame sprayed method on a bent pipe. The process is not only less cumbersome, but again provides a superior product for the market.

Efficiency Estimation

This article discusses the induction heating application features in metallurgical industry for previously unused objects, such as wire coils and wire rod bundles. The analysis of international trends and a forecast of the induction heating application shows a steady expansion of the induction technologies in the metallurgical industry. The article considers the advantages of induction heating in comparison to other competitive technologies. Heat treatment in electrotechnological induction plants is determined by the interconnected electric and thermophysical processes taking place in them, the complex nature of the internal heat sources distribution, the dependence of the distribution pattern of the induction plant on the temperature of the products being processed. It is shown that the investigation results of the induction heating method influence the temperature and time factors in the formation of the structure, the increase in the uniformity of heating, and the quality of the heat treatment of steel wire and wire rod buntle, taking into account the stated technological task. The efficiency estimation of application of medium and high-frequency induction heating of steel wire of various diameters is given. Evaluation of the efficiency improving of the induction heating device, when the heat treatment simultaneous multiple strands of steel wire of equal diameter, united in a bundle, is given.

Forced Cooling

The process of induction heating followed by forced cooling of large-scale castings is considered. The main goal of this study is to develop a reliable design methodology of surface heat treatment process to provide high quality of the treated component. It is assured by determination of the material constants and convection coefficient during heating and cooling experiments carried out on the specimens made of material adequate to the considered large-scale casting. The main part of the investigations was preceded by wide analyses of the mechanical and chemical properties of the tested specimens. The presented global design methodology of large-scale castings gives a possibility to predict the temperature distribution on the hardened surface during induction heating and forced cooling. This allows to select the most adequate parameters and apply them in a real specific process. The obtained results have been analyzed and discussed.

Abstract Because of its speed and ease of control, induction heating can be readily automated and integrated with other processing steps such as forming, quenching, and joining. Completely automated heating/handling/control systems have been developed and are offered by induction equipment manufacturers. This chapter deals with materials handling and automation. First, it summarizes basic considerations such as generic system designs, fixture materials, and special electrical problems to be avoided. Next, it describes and provides examples of materials-handling systems in induction billet heating, bar heating, heat treatment, soldering, brazing, and other induction-based processes. The final section discusses the use of robots for parts handling in induction heating systems.

The Wire

Abstract One of the most important types of heat treatment that high-carbon steel wires are subjected to is the patenting treatment. This process is conducted with the aim of obtaining a fine-grained uniform pearlitic structure which will be susceptible to plastic deformation in drawing processes. Patenting involves two-stage heat treatment that includes heating the wire up to the temperature above Ac3 in a continuous heating furnace (in the temperature range of 850÷1050°C) followed by a rapid cooling in a tank with a lead bath down to the temperature range of 450÷550°C. The patenting process is most significantly influenced by the chemistry of the steel being treated, as well as by the temperature and the rate of heating and cooling of the wire rod or wire being patented. So far, heating up to the austenitizing temperature has been conducted in several-zone continuous gas-fired or electric furnaces. Recently, attempts have been made in a drawing mill to replace this type of furnace with fast induction heating, which should bring about an energy saving, as well as a reduced quantity of scale on the patented wire. This paper presents the analysis of the structure and mechanical properties of wires of high-carbon steel with a carbon content of 0.76%C after the patenting process using induction heating for different levels of the coil induction power.
