Efficient lining for steel-pouring ladles

Abstract

An analysis was made of the reasons for the short service life of the lining of steel-pouring ladles and malfunctions of fountains used for bottom-pouring. A high-temperature adhesive was developed and the most chemically stable refractory materials were chosen for it. The operating regime of steel-pouring ladles in the open-hearth shop at the Revda Hardware-Metallurgical Plant (in Revda) was studied, and based on the study results the shop replaced its fireclay bricks with MKRAP refractories. The authors used those results to also develop a mortar that has increased the life of the lining 30-50%. Use of the highly stable high-temperature adhesive in fountains has reduced metal loss during bottom-pouring operations. © 2013 Springer Science+Business Media New York.
