for melting of l(X)% sponge iron in induction furnace. Introduction Steel scrap is normally the feed stock for the production of steel in induction furnace. The scarcity of the scrap coupled with its varying composition and irregular size and supply is causing concern to the mini steel plants having induction furnaces.
Steel - Electric-arc steelmaking: About one-quarter of the world's steel is produced by the electric-arc method, which uses high-current electric arcs to melt steel scrap and convert it into liquid steel of a specified chemical composition and temperature. External arc heating permits better thermal control than does the basic oxygen process, in which heating is accomplished by the ...
Induction and arc furnaces use electricity to melt steel and cast iron. Melting furnaces for nonferrous materials use fuel oil. Oil-fired furnaces mostly use furnace oil, especially for reheating and heat treatment of materials. Light diesel oil (LDO) is used in furnaces where sulphur is undesirable.
Further, fluxes allow for the coalescence of low melting point slag droplets that otherwise may become emulsified in the liquid metal bath of high frequency induction furnaces. Viscous non-metallic slags can negatively affect coreless, channel, and pressure-pour furnaces, causing slag formations on the furnace and/or inductor walls.
The greatest advantage of the Induction Furnace is its low capital cost compared with other types of Melting Units. Its installation is relatively easier and its operation simpler. Among other advantages, there is very little heat loss from the furnace as he bath is constantly covered and there is practically no noise during its operation.
Melting Solutions Limited can offer complete secondary scrap melting plants for efficient melting of all types of aluminum scrap in a wide range of capacities.. A typical melting plant will consist of: • Basic layout and design of the foundry building with consideration of scrap reception, preparation and storage.
Apr 07, 2013· But as most Induction Furnaces are open-topped, it is difficult to capture and utilize their waste heat. The process requires the usage of External Heating Source. Several methods can be adapted for preheating Scrap and DRI for Induction Furnaces.© R.A.D.E INITIATIVE 2013 | [email protected] 4.
Nov 07, 2013· Calculating the cost for melting metal using an induction furnace is based on the kWh, power consumption, and number of tons, learn how with this formula.
control systems commonly used to control particulate emissions from electric arc and induction furnaces are bag filters, cyclones, and venturi scrubbers. The capture efficiencies of the collection systems are presented in Tables 12.13-1 and 12.13-2. Usually, induction furnaces are uncontrolled. Molten steel is tapped from a furnace into a ladle.
The energy required for the melting process is provided by electrical induction furnace. The feeding of raw material in the induction furnace is on intermittent basis. As one charge of scrap melts, slag is removed from the molten metal and certain alloys are added to achieve the desired grade of steel.
Environmental, Health, and Safety Guidelines FOUNDRIES APRIL 30, 2007 1 WORLD BANK GROUP Environmental, Health, and Safety Guidelines for Foundries Introduction The Environmental, Health, and Safety (EHS) Guidelines are ... cover extraction for induction furnaces to reduce fugitive emissions. Installation of an appropriate furnace hooding
The prime criterion for the commercial acceptance of new advanced melting technologies is that they must not be capital intensive for installation. Emerging technologies such as solar melting, microwave melting, infrared heating, or plasma heating offer unconventional ways of providing enormous amounts of energy effectively to the
May 26, 2015· Induction heating in brazing and soldering applications is readily adaptable to production line methods, permitting strategic arrangement of the equipment in an assembly line, and if necessary ...
copper-bearing scrap metal and smelting resi-dues requires preparation of the scrap (e.g., re-moval of insulation) prior to feeding into the primary process. Electric arc furnaces using scrap as feed are also common. Waste Characteristics The principal air pollutants emitted from the pro-cesses are sulfur dioxide and particulate matter.

Furnace Charging System Options. Furnace charging systems are designed to deliver charge material to the furnace quickly to allow for maximum utilization of the melting system. We offer a variety of systems for assembling and moving scrap and other charge materials to the melt deck and into the furnace.
The development of Induction Furnaces starts as far back as Michael Faraday, who discovered the principle of electromagnetic induction. However it was not until the late 1870's when De Ferranti, in Europe began experiments on Induction furnaces. In 1890,Edward Allen Colby patented an induction furnace for melting metals.

Oct 01, 2014· These furnaces use induction heating to produce heat, which is a rather clean, energy-efficient way of producing heat. Therefore, no harmful pollutants are released during the melting process, and induction heating spreads throughout the furnace efficiently allow the heat to be absorbed by scrap in an efficient way.

Direct-reduced iron has about the same iron content as pig iron, typically 90–94% total iron (depending on the quality of the raw ore) so it is an excellent feedstock for the electric furnaces used by mini mills, allowing them to use lower grades of scrap for the rest of the charge or to produce higher grades of steel.
