Induction Furnace

Se analiza el mercado de chatarra ferrosa en general,  y en particular el mercado argentino, con énfasis en el consumo de las fundiciones. Se desarrollan brevemente temas como disponibilidad, precio, modelos de ptimización de la carga del horno y la compra de chatarra, los diferentes tipos de chatarra, la recepción en la planta; los equipos necesarios para la preparación de la chatarra y la influencia del tipo de horno y  del material a fundir

Furnaces are most commonly used for melting of materials. Induction furnaces are more beneficial as no fuel is required. It is a problem to find life of Induction Melting Furnace wall under thermal fatigue. The induction melting furnace wall is made of alumina ramming mass which is one kind of refractory material. The failure occurs due to cyclic thermal stresses. Temperature distribution and thermal stress distribution fields of the induction melting furnace refractory wall were calculated by using ANSYS finite element analysis software based on the physical description of its failure under thermal fatigue conditions. The thermal fatigue life of the refractory wall is required to be found out by means of thermal stresses created inside the refractory wall of induction melting furnace from modified S – log N Curve.

Automatic frequency control enables a variable induction heating load to be driven at its resonant frequency, ensuring maximum power transfer to the load throughout the heating cycle. Analysis and experimental results of the resonance locked-loop are presented to illustrate the performance of the system

There is a measure of agreement that solar grade silicon (SGS) with impurities in the parts per million (ppmw) can be obtained cost effectively from metallurgical grade silicon (MGSi) and used to yield solar cells with performance comparable to Si made using the standard Siemens process. In this paper we present the rationale for SGS development, as well as preliminary
