<p>1,112,368. Control valves for ladles. PADERWERK GEBR. BENTELER. 1 Nov., 1965 [25 Nov.,1964], No. 46108/65. Heading F4B. A slide valve for a steel casting ladle comprises a housing 6 for a slidable support frame 7, a slide block 8 mounted therein and a discharge block 9, and also an inlet block 2 with a funnel entry 13 having an apex angle of at least 120 degrees, a neck 14 about 60 mm. long and a free opening area of at least 150 sq. ems., said funnel being initially filled with granular quartz. Members 8 and 9 are united by a refractory mortar and mounted on frame 7 using a lower quality mortar, the slide block 8 being pressed against a bottom block 3 by adjustable eye bolts 18. These latter are swung from housing 6 and engage curved seatings in a clamping plate 17 by domed portions 19, Fig. 3 (not shown). Frame 7 slides on lower and lateral guide rails being actuated by an hydraulic or electric motor through an adjustable coupling member, Fig. 6 (not shown). In a modification, Fig. 5 (not shown), the slide block 8 is displaceable with respect to the discharge block 9. The funnel neck 14 may be lined with replaceable bushes, Figs. 9-11 (not shown). The discharge block 9 may have a counterbore or projecting mouth surface, Figs. 12-14 (not shown), or may have an inner insert of wear-resistant material and an outer part of heat-resistant material, Figs. 15-20 (not shown). The invention may incorporate a setting or locating jig for the insertion and adjustment of the interfitting refractory components, Figs. 21-24 (not shown).</p> |
