Estudo do comportamento térmico da temperatura do ferro fundido cinzento durante o transporte na panela de transferência

Abstract

Casting is a metallurgical manufacturing process that allows the high scale production of materials and semi-finished products in the metallurgy, with the advancement of technology in our daily lives this process is becoming increasingly accurate and with a relatively low production cost. The present study evaluated the thermal losses of gray cast iron during the transfer process from the channel furnace to the pouring furnace. This analysis allowed to relate the low thermal efficiency of the transfer ladle insulation with the high consumption of electric energy by the furnace, causing a high production cost. The experimental procedure was performed using the Six Sigma methodology. The experimental results with the improvements were: reduction of 34.5% in the thermal loss of the cast iron during the whole process, reduction of 14.5% in the electric energy consumption in the holding furnace. The experimental results obtained are in agreement with the values found in the literature.
