Estudo da influência da temperatura na alteração do revestimento permanente do fundo de uma panela de aço em uma aciaria elétrica

Abstract

Steel is an iron-carbon alloy, which can be used in the most diverse sectors of the economy due to its low manufacturing cost and its chemical and mechanical properties. Refractory materials are part of the manufacture of steel through the composition of the internal lining in the equipment used in the manufacture of the same. Different types of refractory materials can be applied in these equipments, namely: dolomitic, magnesium, aluminous. In the present work, the modification of the thickness of the permanent coating of the steel ladle will be discussed in order to increase the weight of cast steel, performing the necessary measurements and comparisons to guarantee operational safety, obtaining results within the established limits, enabling the change.
