Minimising energy consumption during the inductive melting of metal alloys is an on-going concern for plant manufacturers and operators. However, little attention is paid in this context to the potential which lies in the heat content (or enthalpy) of the melt in question. The following deliberations show that the composition of the input materials has a considerable influence on the heat content of alloy melts and thus on their energy consumption. The enthalpies for various input materials can be derived from tabular thermochemical data and used in inductive melting operations.

NIWE project will demonstrate a new production process able to decrease the embodied energy of the foundry products by over 25%, reducing drastically its carbon footprint. The demonstration will be performed in the aluminium, iron and steel sectors. The expected energy efficiency gains are due to a new furnace that, by means of a power transmission system based on induction, will allow a highly flexible production. This increase on the production flexibility attends to the current variability of the foundry products demand. The current crisis has introduced a high variability in the demand, which can be measured in terms of quantity and diversity of the demanded products. The manufacturers are now forced to start and stop many times their production chains, change the moulds and, the most important in energy penalty terms, to reheat many times big quantities of raw materials. Consequently, the cost efficiency of the process has suffered a high decrease. NIWE tackles these actual and current problems by providing a new furnace that will take the power by an inductive coupling. This will provide a very quick power transmission from the grid to the furnace. This power will be supplied to the heating system, which, depending on the foundry material could consist on resistances or induction heating. The rapidity of the power transmission system, as well as the wireless operation, will allow the use of smaller furnaces. This way, the reserve of melted material for feeding the moulds will be smaller, and therefore the required energy to maintain it melted. In addition, the wireless furnace will provide a flexible operation, allowing a quick modification of the factory layout, which will be based on easy interchangeable furnaces of different types andsizes, depending on the demand.

The first part of this article examined the features of induction furnaces and their special significance for steel production. The second part of the article now focuses on the use of the induction furnace in the steelmaking plant. The preconditions for the use of the induction crucible furnace in two sectors in the steelmaking plant now exist, following the development of induction technology up to connected loads of over 40 MW per inverter and power densities of between 600 and 800 kW per tonne of furnace capacity: the induction furnace firstly constitutes an alternative to the electric arc furnace as a melting facility for mini-steelplants with an annual production of 100 to 900 thousand tonnes and, secondly, it is the most suitable melting method for ferroalloys charged in liquid form into the unheated ladle in the production of stainless steels.

The continuously increasing importance of the CO 2 balance and of conservation of resources is resulting in ever greater demands for high energy-efficiency in the process used for heating of forging ingots. Plant and process engineering play roles of parallel significance in the fulfillment of these requirements, and this article focuses on both in equal degree. The shares of the individual components in the overall energy consumption of an induction heating installation are therefore firstly determined, and their respective potentials for optimization then discussed. The quality of the heating process itself, and its optimum design for reduction of energy consumption, are then examined.

The foundry group of the voestalpine Group operates a foundry to produce heavy steel castings with a weight of 1 to 200 t per casting. The great majority of the melt required by the foundry comes from the BOF steel works located on the same site. However, the recyclable material accrued when casting steel at around 50 % cannot be profitably used there. An induction crucible furnace was therefore installed to melt this valuable recycled scrap for the foundry. How this is integrated in the production process and the manufactures produced in this special deployment are described in this contribution.

After the development of induction technology with converter outputs of over 40 MW for crucible furnaces with capacities of more than 80 t, the induction furnace offers itself as an alternative to the electric arc furnace. Apart from saving the electrode costs and the low requirements on the electricity grid, the main benefits offered by induction furnaces are the high yield from the feed materials and low pollution of the environment and workplaces. The low metal losses becomes an economic factor, particularly when stainless steels are produced; although promising results have also been obtained in recent times for the inductive melting of carbon steels. In what follows, the characteristic properties of the induction furnace are first described before some example systems for steelmaking are discussed.

One of the primary development targets in contemporary automotive technology is the reduction of fuel consumption via the enhancement of the efficiency of turbocharged gasoline engines. The results include an increase in exhaust temperature at the exhaust ports to over 1000° C and greater demands on the mechanical strength, creep behaviour, fatigue resistance, microstrucural stability and resistance to oxidation of the materials used.


Patent
ABP Induction Systems GmbH | Date: 2013-11-07

A method and an apparatus for detecting a ground fault in an induction furnace as well as an induction furnace are described. When a ground fault is detected by means of the ground-fault detector the ground fault is localized. By doing this it is determined if the ground fault is caused by a failure of the refractory lining or by other reasons. If the ground fault is caused by other reasons it is ascertained if it is caused by a defective magnetic yoke insulation. Furthermore, it can be ascertained which magnetic yoke of the induction furnace causes a ground fault. In this manner the induction furnace can be operated with improved security and smaller expense.


Patent
ABP Induction Systems GmbH | Date: 2013-11-07

An apparatus for detecting ground faults in a multifurnace installation with at least two induction furnaces and a multifurnace installation are described. A ground-fault sensor is associated with each induction furnace and is connected to the electrical supply line to the induction furnace coil. Furthermore, the apparatus has a ground-leak sensor. Moreover, the apparatus includes an additional ground-fault sensor that measures at the same location as the ground-leak sensor. In this manner an improvement of security during the operation of the system is obtained.
