Observations & Recommendations
BR - Boiler & Steam Line
ObservationRecommendationUnit SavingsAnnual SavingsInvestmentROIStatus
Un-necessary superheating of metal is observed due to the faster heating rate. (During the final stage of melting, the temperature of molten metal rises at a rate of 7°C per minute)Manually adjust the power of furnace during the final stage of melting.3,55,395₹24,87,768₹1,00,0000.5
Scrap is loaded without weighing and thus the furnace is over loaded to adjust the composition by trial and error methodProper weighing mechanism should be incorporated to avoid the overloading of furnace and reduce the testing time.
