The principal goals of this paper is to decrease fuel consumption, increased efficiency of energy utilization and assuring that new pollutants are not generated by new waste heat recovery system. In steel manufacturing company ladles are used to transfer molten metal from induction furnace to Concast department but while transferring molten metal it losses much of heat to the environment via convection & radiation from ladle. A ladle with high heat content is desirable for steel making .Casting into cooler ladles also leads to high localized wear due to thermal spalling. A possibility of specific casting advantages, lowering in tapping temperatures and associated cost savings occurred by minimizing heat loss from the melt led to the concept of preheating and insulation in the steel ladles. The use of insulating linings allows companies to adopt a lower tapping or holding temperature practice and to reduce the variation in metal pouring temperatures. This results in improved control of metal chemistry, lower energy consumption, a reduction in furnace refractory consumption, and fewer slag inclusions and temperature-related casting defects. By preventing heat losses from ladles we can reduce considerable heat & power consumption.

Keywords- Insulating material, Heat loss, Ladle shell temperature, Furnace tapping temperature, Energy consumption
