Product Description
Being a leader in the industry, we are engaged in offering a quality range of Air Pollution Control Device for Steel Induction Furnace. The offered furnace is designed by our experts using latest techniques and premium quality components. Provided furnace is used in various applications such as automobiles and chemicals industry. This furnace is checked against several quality parameters by our quality inspectors.


Air Pollution Control Device For Steel Induction Furnace is major steel producing technology using scrap & sponge iron (Directly Reduced Iron) as main raw material. This technology contributes significant steel making capacity in secondary steel sector in India.

It has some distinct advantages:

  • Low Project Capital Cost
  • Low Energy Cost
  • Consumes steel scrap which is a major solid waste
  • Environment Friendly, as it produces lower emission than Primary Blast Furnace
  • Uses clean fuel i.e. electrical power

Can be set up near source which saves transportation cost of raw material as well as finished goods

Manufacturing Process:

Air Pollution Control Device For Steel Induction Furnace includes melting of various types of steel scrap in a pot. 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. Molten metal is then poured in to refractory lined buckets from where it is further poured in different sizes moulds to get the desired size of steel. Ingot/Billet is allowed to cool down and then the product is separated from the moulds. Flue gases are generated during melting of scrap. The characteristics and volume of these gases mainly depends upon type of scrap used in the furnace, i.e. with the degree of contamination in the Scrap.

Air Pollution:

Steel scrap which comes from various sources and generally has contamination/coating etc on it. When this scrap is heated contamination/coating etc disintegrates from steel and comes out either as slag or becomes air borne, thus causing air pollution.

The major source of Air Pollution are:

  • Dust & Dirt
  • Rust
  • Oil & Grease
  • Paint
  • Galvanized Iron
  • PVC Coated Steel

Capacity Calculation of Required Equipment: The volumetric capacity of Air Pollution cannot be judged as such but fair engineering estimation can be made with input data like:

  • Furnace Capacity
  • Power Rating in KWH
  • Detail Drawing of Furnace
  • Air Cooler Arrangement for workers at Furnace Platform

Characteristics of Air Pollution Generated In Induction Furnace :

  • Pollutant : Dust & Dirt, Metal Oxide & Traces of NOx, SO2, CO, CO2
  • Concentration : Average - 600-800 mg/Nm3, Max - 1200-1400 mg/Nm3
  • Temperature : At Hood: 250°-300°C, At Bag House: 80-120°C
  • Nature of Dust: Non Sticky, Non Abrasive

Control Practices: The Control Practice adopted in controlling air pollution in this industry mainly depends upon following parameters:

  • Dust/Gas Concentration at Inlet
  • Discharge Standards
  • Temperature of Fuel Gases
  • Nature of Pollutant i.e. Dust or Gaseous
  • Nature of Dust i.e. Sticky, Abrasive
  • Nature of Gases i.e. Corrosive, Non Corrosive
