Achievements» COAL FIRED FURNACE FOR MELTING NON-FERROUS METALS


  1. Application :
    It is used for melting of non-ferrous metals such as Brass, Bell Metal, Copper, Bronze, Zinc, Lead etc., within a temperature range of 1000 0 C to 1200 0 C through burning raw coal. It is a low cost furnace and can be utilised for casting of non-ferrous metal for making utensils, handicrafts, small machine parts etc., in cottage or small-scale industries. Melting is rapid and does not create any smoke during burning of coal.
  2. Raw Materials:
    Few pieces of refractory bricks, a mild steel grate for construction of furnace, and Non -ferrous metals for casting.
  3. Process Features:
    Coal burns in the furnace around the ladle filled with non-ferrous metals. A small blower supplies the air to the grate of the furnace for burning of fuel at high temperature (1200 0 C). 10 kg metal melts within one hour at 1000 0C in batch process. This is a simple and low cost furnace.
  4. Market:
    5000 units/year
  5. Status of Commercialisation:
