Torpedo Car Lining With Unfired Zero-Carbon Bricks: Performance and Energy Savings Achievements

The torpedo car is a metallurgical vessel used for transportation and pretreatment of the pig iron from the blast furnace to the converter. Temperature drop is considerable due to the long distance and brings negative effects, such as increase in energy consumption, decrease in the metal recovery rate and even solidification of molten iron. Heat loss is principally determined by the types and properties of torpedo refractory linings. A new generation of unfired zero-carbon refractories was developed to replace carbon-containing bricks. Energy savings and better performance in field trials are highlighted in this work.
