Definitions

  • the casting must have solidified above the lowering rolls because squeeze cracks tend to form on castings pressed by the lowering rolls whilst their core is still liquid.
  • the distance between the ingot mould and the lowering rolls must be so large that, with a given lowering speed, the crater point is above the lowering rolls. -It is also possible to reduce the lowering speed, in order to produce a sulficiently long solidification time.
  • the castings are distorted by about 2 to 4 mm. by the contact pressure of the lowering rolls, and this has an unfavourable effect particularly with round castings which tend to become oval or unround.
  • the substantial advantage of the invention is that the arrangement of the transport rolls becomes independent of the position of the crater. These rolls may be located above the crater in the direction towards the ingot hold without incurring the risk of causing squeeze cracks in the casting, and reduce substantially the overall structural height of the plant.
  • FIGURES l to 3 show diagrammatically in FIGURES l to 3 an arrangement for carrying out the method according to the invention.
  • the ladle 1 is located above the distributor 2.
  • an ingot mold 4 constructed for casting three continuous castings 5.
  • the lowering rolls are shown at 6.
  • the castings 5 form continuous castings and are interconnected by webs 7.
  • the lowering rolls 6 have roll rings 8 which collaborate with the webs 7.
  • the roll rings 8 are positively connected with the rolls 6 by pass springs 9.
  • distance rings 10 and clamping rings 11 serve to transmit axial forces to the rolls 6.
  • the connection between the roll rings '8 and the rolls 6 may also be effected by other known means.
  • a continuous casting a method for lowering and guiding a multiple cast casting of preferably round cross-section with individual ingots interconnected by webs that are thin in comparison with the cross-sectional area of said ingots, the improvement comprising, using a roll contact pressure only on said webs and solely for lowering and guiding said casting.
