摘要

Improvements in the methods of preparation of compositions for plugging blast furnace pits, characterized by loading, in separate silos, mineral elements of different granulometries, constituted by a refractory clay, a refractory aggregate of high mechanical strength and a material of high content carbon, transfer to a tank, which is heated to a temperature of 130-200º c, a thermosetting resin, dose from about 70 to about 30% of the mineral element in a weighing hopper, knead dry this mixture to which it is added. % polymerizable hydrocarbon binder formed by a hydrocarbon derivative obtained from the distillation of crude petroleum oil having a boiling point higher than 200ºC and emptying the kneader when these components are perfectly associated and no segregation occurs.
