A cubical shell furnace, which will be stationary furnace, used in melting all kinds of non-ferrous melting, lead oxide kettle, zinc kettle etc., indirect type melting ensures the loss of metals due to oxidation/carbon deposit by the fuel or combustion properties. Furnace is lined with refractory and insulation brick to hold the liquid metal to a temperature of 1200 deg.C. This furnace lining by a brick is formed with extra locks mechanically to ensure the lining the tightness and holds the crucible to not to fall of while tilting the furnace. Our specialties are manual operating furnace, automatic operating furnace, air/fuel ratio regulating system, mass flow control system, pressure balancing system, flue control system.
