METHOD OF CONTINUOUSLY PRODUCING VITREOUS BLAST FURNACE SLAG

摘要

The invention relates to a process for continuously producing a glassy or vitrified blast furnace slag, in which the slag is applied onto a cooling roll or onto articulately interlinked cooling plates conducted as an endless conveyor belt over deflection pulleys and wherein cooling of the slag is effected dry, wherein the liquid slag is supplied to an intermediate storage and from that intermediate storage is continuously applied onto the cooling plate belt, or cooling roll, via a distributing channel in parallel strands at temperatures of above 1350° C., whereupon the cooled slag is thrown off and comminuted or granulated dry in a crusher. The invention, furthermore, relates to an arrangement for carrying out the process.
