ResumoO controle da transferência de calor é uma das principais funções que o fluxante exerce durante aplicação no molde de lingotamento contínuo. O fluxo de calor na interface placa / molde deve estar adequado aos parâmetros de processo e ao tipo de aço, caso contrário pode provocar preferencialmente alarmes de agarramento em aços baixo carbono e trincas longitudinais em aços médio carbono, podendo levar até ao breakout. Este trabalho tem o objetivo de caracterizar os filmes de escória aplicados em aços baixo (Filme BC) e médio carbono (Filme MC), ambos comerciais, utilizando as análises de Microscopia Eletrônica de Varredura (MEV) com Energia Dispersiva de raios-X (EDS) acoplado e Difratometria de raios-X (DRX). As diferenças entre os filmes de escórias foram discutidas e relacionadas aos dados presentes na literatura. Palavras-chave: Transferência de calor; Fluxante; Cuspidina; Lingotamento contínuo. ANALYSIS OF SLAG FILMS APPLIED IN LOW AND MEDIUM CARBON STEEL AbstractThe heat transfer control is one of the main function that the mould flux works during the application in the mold at the continuous casting machine. The heat flux at the interface mold / strand must be appropriate to the process parameters and type of steel, otherwise it may cause preferably alarms in low carbon steels and longitudinal cracks in medium carbon steels, which may lead to the breakout. This work aims to characterize the slag films applied in low and medium carbon steels, both commercial, using the Scanning Electron Microscopy (SEM) with Energy Dispersive Scanning (EDS) coupled and X-ray Diffraction (XRD). The differences between then were discussed and compared with data from literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
