1466308 Slide valves for metallurgical ladles USS ENGS & CONSULTANTS Inc 17 Oct 1974 [17 Oct 1973] 45071/74 Heading F4B In a slide valve for a metallurgical vessel, of the type in which the sliding plate 7 is urged against the fixed plate 6 by spring-loaded bolts 5, the heads of the bolts are formed with a number of projections so that there is a space between the body of the bolt head and the lower surface of the sliding plate for the passage of cooling air. The bolt head 10 is preferably square with rounded corners, formed by removing segments from a circular head, and the projections 14 are formed by cutting grooves in the bolt head to leave projections of smaller width than the spacing grooves. The projections may be frusto-pyramidal in form.
