Definitions

  • the first step is taken with the aid of an ingot mould in which the metal is cast, the casting being removed from the mould and reheated to convert it into a more or less finished product.
  • a casting process using a horizontal mould consists in pouring the molten metal from a ladle into a furnace; causing it to pass from the furnace into a molten metal container, and to pass from the latter through a conduit of refractory material and of a truncated conical shape; causing the molten metal to come into contact by its first jet with a conveying device having a dovetail or keying part by which the metal is cooled so that it is solidified therewith; causing, by the conveying device, the metal to pass through two ingot moulds, the first of which determines its final shape and both ensuring a progressive cooling of the metal, Whilst the second mould has provision for taking up play; and finally causing the casting to pass between conveying and shaping rollers, so that a finished or semi-finished product can be obtained in a single operation.
  • the danger of hollows is eliminated by the constant flow of the steel in the container which pushes the metal towards the ingot moulds under the action of the atmospheric pressure and the weight of the column of molten metal.
  • the slab is sound from end to end and the required chemical properties are uniform along its entire length.
  • Figure la is an elevational view of the said apparatus.
  • Figure 2 is an elevational view, partly in section, of part of the apparatus, showing the container and the conduit of refractory material.
  • Figure 3 is a section along the line IIIIII of Figure 2.
  • Figure 4 is a section along the line IV-IV of Figure 2.
  • Figure 5 is a perspective view of a wedge for taking up clearance due to shrinkage of the slab through the ingot mould.
  • the horizontal mechanical casting device consists mainly of the following parts:
  • the mobile ladle 1 is moved in the direction of the intermediate furnace 2 and its contents are poured into the same; the fused metal passes at the desired time into the container 3 to be admitted into a conduit 4 made of refractory material, where it comes into contact with a conveying device which draws the metal into the interior of the first ingot mould 5 which imparts to the metal its final form before it passes into the ingot mould 6 which is provided along its entire length and width with devices for taking up play due to shrinkage.
  • the rollers 8 which alter the shape of the slab, draw the latter over intermediate rollers 7 which serve as a roller track for the said slab to direct it through a furnace 9 ( Figure l) for maintaining its temperature before receiving its final form by passing in due course between the flattening rollers 10.
  • the nose 4 and the fireproof plug 4 are rigid with a withdrawal member 11 which draws the metal in the direction of the ingot moulds.
  • the conduit 4 of refractory material is given the shape of a truncated cone whose large base is situated at the inlet side of the ingot moulds 5 and 6.
  • the ingot mould 5 is provided with a series of hollow longitudinal elements 5 made rigid with an outside envelope 5 by bolts 5 which ensure tightness between the hollow parts 5 and the said envelope 5*.
  • the hollow parts 5 in the interior of which the cooling water circulates are made of a metal with a good heat conductivity, such as brass which ensures the required cooling of the metal under treatment.
  • a metal with a good heat conductivity such as brass which ensures the required cooling of the metal under treatment.
  • the outside envelope 5 serving as a support for the hollow parts 5 is fitted with ramps 5 which, under the action of thewedges 5 ( Figure 5) which are controlled by bolts 5 and the nuts 5*, constrain the envelope 5 to move in the desired direction, thereby putting into contact the hollow parts 5 with the cooled slab, and contracting the ingot mould 6; this regulation is carried out all along the ingot mould 6 and when the slab leaves the same and takes support on the roller track 7, the device for taking up the play due to shrinkage is wedged in the acting position and should normally not be disturbed again as long as the casting continues, which depends on the quantity of metal fed into the container 3.
  • An ingot mold for the continuous casting of a metal comprising four exterior walls fixed in operative association to confine a chamber, a plurality of hollow members in the chamber and in operative association to provide four inner walls defining a passage open at both ends for movement of the ingot, the hollow members accommodating a cooling medium, wedge means between the exterior walls and the hollow members to adjust the relative positions thereof thereby to control the dimensions of the passage, and control means coupled to the wedge means and extending externally of the exterior walls to provide an external control of the dimensions of the passage.
  • wedge means comprise prismatic members defining elongated slots and rods coupled with the exterior walls and positioned in the slots to constitute guides for the prismatic members.
