Siliceous refractories for iron ladles of the mixer type

Conclusions For the first time in the linings of iron-carrying ladles of the mixer type we have tested siliceous refractory products. They showed satisfactory resistance in all zones of the ladle in contact with metal, and especially in the zone where the iron jet hits the lining, which means that in contrast to ladles with mullite-silica linings we can carry out the complete campaign for the ladle without repairing this section.In the zones not contacting the iron, and in the central parts of the lining made of siliceous articles, they are less resistant than those made of mullite-silica.On the basis of these tests in mixer-type ladles we recommend the use of combined linings from siliceous and high-alumina articles.The annual savings from the use of siliceous linings is 67,000 rubles.Translated from Ogneupory, No. 2, pp. 21–24, February, 1982.
