Optimization of Aluminum Deoxidation Practice in the Ladle Furnace

Aluminum is an important and expensive deoxidant. In order to optimize its consumption and assess their efficiency under ladle furnace conditions, a research work was carried out at Mittal Steel Lázaro Cárdenas. Samples from the steel melt and the slag were taken at the beginning of the process and after the first aluminum addition were made. The information obtained was analyzed in order to define the amount of aluminum required based on the initial oxidation conditions and measure the impact of the initial oxidation conditions on aluminum efficiency. The results are expressed as correlations and suggestions are also made to increase aluminum efficiency, thus, contributing to minimize aluminum consumption.
