Definitions

  • the invention relates to a liquid-cooled mold for a continuous caster a mold body made of a material with high thermal conductivity, like copper or a copper alloy.
  • Chill molds are designed to extract heat from the molten metal and, initially, through the the formation of a strand shell enables the strand to solidify.
  • mold geometries are in use, like mold tubes in round, rectangular or complex form. Mold plates are used for square / rectangular blooms or for slabs with larger Aspect ratio used. There are also special geometries, such as pre-profiles for double-T beams and thin slab molds with funnel extension in the upper one Plate area for receiving the pouring nozzle. It is characteristic of all these molds that homogeneous cooling of the surfaces is sought. Make the corner areas Special cases, since z. B. due to the design of plate molds with butt edges disturbed cooling are present. There are also areas with larger areas Given volumes of material for the rear fasteners that with Specially designed groove-like coolant channels with respect to the same Cooling can be adjusted again.
  • the local stress conditions when using funnel mold plates are on the one hand operational. They are essentially determined by on the casting side the type of steel / casting temperature, the speed, the lubrication / cooling conditions of the mold powder, the geometry of the pouring nozzle and the associated flow of the Melt. On the other hand, cooling water quality and cooling water quantity determine on the water side and water speed the mold temperatures. These sizes are partly due to the mold construction - as with the geometry of the Coolant channels - determined.
  • the invention is based on the object To create mold body, in which the heat flow in the bathroom mirror area increases is and the risk of cracking in the thermally and mechanically stressed Areas can be avoided.
  • the core point of the invention thus forms the measure in the supercritically claimed Areas on both sides of the funnel a significantly stronger cooling of the Adjust mold body.
  • the cooling capacity is proposed in these critical areas preferably by 10 to 20% over the increase horizontal neighboring areas.
  • Coolant channels can e.g. B. advantageous here be set closer so that the cooled area increases.
  • the coolant channels can also be brought closer to the surface locally; in this Case, one works unusually with different - effectively effective - cooling wall thicknesses above the cooling water.
  • wide side plates can be formed with groove-like coolant channels in the critical areas of the funnel transition with additional cooling holes Mistake; here too surprisingly increases despite less Wall thickness the crack resistance of the mold material and thus the total service life the mold plate.
  • the funnel mold plate 1 shown in FIG. 1 has the highest thermal stress at the horizontal outlet (vertical line C) of the funnel 2 on the casting side. As a direct result, there is a maximum area-related heat flow of 4.7 to 5.2 MW / m 2 at C in the casting direction GR directly below the bath level 3. There are arithmetically determined maximum temperatures of approximately 400 ° C. on the casting side 4 of the mold plate 1.
  • the cooling grooves 6 which are introduced more deeply (wall thickness between casting and cooling surface 18 mm instead of 20 mm) Intensively cooled area 5 extends in the present case over the following areas (see FIG. 1): Length horizontally from the turning point B of the funnel 2 over 370 mm to the end point D. The more intensive cooling area extends from the top edge of the plate 7 to 200 mm in the casting direction GR; this is followed by a transition zone 8 of 50 mm, in which the depth d of the cooling grooves 6 is adjusted.
