Definitions

  • the invention relates to continuous casting, and relates more particularly to molds for continuous casting which have a casting mold passage that is open at top and bottom.
  • continuous casting includes not only continuous casting but also semi-continuous casting and the like.
  • Tungsten As a covering material.
  • a still further object of the invention is to provide such a covering that need not be highly polished.
  • the invention consists in the novel construction, arrangement and combination of various devices, elements and parts, as set forth in the claim-s hereof, one embodiment of the same being illustrated in the accompanying drawings and described in the specification.
  • FIG. 1 is a fragmentary sectional view of a plate of a mold for continuous casting, in accordance with the invention.
  • FIG. 2 is an elevational view partly in section, on a smaller scale, of a mold for continuous casting, the mold passage of which is surrounded by plates of the type shown in FIG. 1.
  • a plate 1 that is composed of copper and which forms a structural element to be used in assembly with other similar plates in a continuous casting mold of the type shown in FIG. 2.
  • grooves 2 are formed in the abutment end surfaces of the plate 1.
  • Each groove 2 has a width of about .7 millimeter and a depth of about 3 millimeters.
  • On the inner surface of the plate there is a layer or covering 3 of sprayed-on molybdenum.
  • the inner surfaces of the plates are joined in the mold to surround an open casting mold passage through which the casting metal, for instance molten iron and 'steel, passes.
  • the sprayed molybdenum covering 3 lines the passage, and thereby renders the passage, which is surrounded by copper, nonethe less highly resistant to wear and abrasion.
  • the abutment end surfaces form edge-s with said inner surface.
  • the grooves 2 are disposed adjacent and angularly offset from said inner surface of the plate 1 that is covered by the covering 3.
  • the sprayed molybdenum covering extends not only on the inner surface, but also beyond the aforesaid edges of the inner surface into the grooves 2 in the end faces of the plate 1. Where grooves 2 are provided, the sprayed material will fit the grooves, as it extends from the covering 3 into the grooves 2.
  • the thickness of the covering 3 along the inner surface is from about 0.1 to about 0.8 millimeter and preferably from 0.2 to 0.5 millimeter.
  • the covering 3 requires but light smoothing, and dispenses with the need for a highly polished surface.
  • the extension of the covering into the grooves 2 has the advantage that it avoids an overlapping of the base metal, and renders possible the assembling of the plates without need for finishing the abutment end faces. It furthermore serves as a safety measure in that, should the plates 1 warp and thereby the joints between adjoining plates open up, the casting metal will be prevented from coming in touch with the base metal.
  • Each plate 1 has cooling channels 4 which, as best shown in FIG. 2, are connected to a cooling conduit 5.
  • the plates 1 are held together in their assembled state in the mold by means of a well known suitable holding device 6.
  • the good heat conductivity characteristics of molybdenum as compared to chromium offers the advantage that an increased thickness of the covering 3 does not adversely affect the cooling effects of the mold.
  • the instant sprayed covering 3 offers simplicity and economic advantages; repairs are done faster and at less cost.
  • a water cooled mold for use in continuous casting formed of a plurality of copper plates having inner surfaces defining an open casing mold passage, each inner 10 surface having a sprayed molybdenum covering, whereby said passage will be lined by the molybdenum covering of the plates, each plate having abutment end faces adjacent said surface, said end faces defining edges with said surface, and grooves defined in each end face adjacent said edge, each of said grooves having a width of about 0.7 millimeters and a depth of about 3 millimeters, said covering extending into said grooves.
  • a copper plate forming a part of a continuous 5 grooves.
