Proposta de melhoria dos pés do MLLB para o transporte e manuseio do metal ladle na Mozal

Abstract

MOZAL is divided into several departments, and only two are relevant for this work: the Reduction department, responsible for aluminum casting, and the Cast House, which is responsible for pouring liquid aluminum into molds to form ingots. For this purpose, a structure called a Metal Ladle Lifting Beam (MLLB) is used. If any part of its structure is defective, it can affect the transportation of the Metal Ladle containing the liquid aluminum, thus negatively impacting MOZAL's production process. The study was conducted using defective Metal Ladle Lifting Beams present in the OUTOTEC workshop, used as a sample to find a solution that eliminates or mitigates, as much as possible, the problem of warping of the MLLB feet in strong contact with the Metal Ladle. The proposed solution showed positive results in the MLLB provided by Mozal for modifications and testing, and thus approximately 20 existing MLLBs at MOZAL will undergo modification to the new solution.
