About AIIFA

The All India Induction Furnaces Association (AIIFA) is one of the premier industry Associations’ of the country in the secondary steel sectors. AIIFA represents the interest of Electric Induction Melting Furnace industry of the country. Its members are engaged in the production of Mild Steels, Low Alloy Steels, Stainless Steels, Grinding Media and Special Cast Iron castings through Electric Induction Melting Furnaces.   The Association is functioning for the last 28 years with its Head Office located at Delhi. The Association has nine Chapters located at Chennai, Hyderabad, Mumbai, Indore, Cuttack, Bhiwadi, Mandi Gobindgarh, Ludhiana and Goa.

AIIFA is an effective link and medium of communication between the Induction Melting Furnace units and various Ministries of Government of India and Professional Institutions, R&D Centres.  The Association represents on various committees of Ministry of Steel and other bodies of Government of India dealing with statutory regulations, policy making, Excise and Customs, quality standardization, etc. related to the iron and steel industry.

The Association, besides raising various issues with the government authorities for redressal and taking part in Policy making, disseminates latest and important techno-economic information to its members, brings out fortnightly newsletter featuring important news on iron and steel industry and Customs & Excise related notification/circulars, etc.

In recognition of attaining excellence in production, quality control, energy efficiency, overall entrepreneurship, etc. the Association gives Dhatu Nayak & Ispat Udyog Ratan Award to selected units every year.

The Principle of Induction Melting Furnace is based on Michael Faraday’s principle of generating Electro Magnetic induced currents

In Induction Furnace, Electric Power is converted into heat by a process of induced current produced through strong magnetic fields when a metallic conductor is placed within the magnetic field.

The metallic charge in the Induction Furnace, i.e. scrap with certain proportion of sponge iron, resist the flow of the induced current.

This electrical resistance in the charge produces heat resulting melting of the charge mix

HISTORY OF STEEL MAKING BY INDUCTION FURNACES: -

  • Medium Frequency Induction Furnace was developed in the world (Germany, USA and U.K.) in 70s, having found that the Medium Frequency Induction Furnaces were suitable for Foundries.
  • In India, small capacity Induction Furnaces were used for manufacturing of Stainless Steel using imported Stainless Steel scrap in early 80s.  This ushered in the manufacturing of stainless steel through Induction Furnaces.
  • Compared to Electric Arc Furnace, pick up of carbon is avoided in Induction Furnaces.  Also power consumption in Induction Furnace is lower than Electric Arc Furnace.
  • Soon trials were made to make Mild Steel in Induction Furnaces in mid 80s.  Finding success of the trial, Induction Melting Furnace units were installed in a big way in North, West and Southern States of the country.  Subsequently withdrawal of statutory requirement of procuring licence to set up units in the year 1990, helped the growth of the Induction Melting Furnaces in the country.
