Definitions

  • the invention relates to a method for producing a heavy plate from steel, in particular with a thickness of more than 50 mm, by hot rolling a primary material in several passes.
  • ESU process electro slag remelting process
  • B.E.S.T. process B.E.S.T. process
  • the invention aims to avoid the disadvantages and difficulties described and has as its object to provide a method of the type described above, with which heavy plates, in particular heavy plates of great thickness, can be produced inexpensively and in high-quality, error-free quality.
  • This object is achieved in that at least two slabs of the same steel quality are stacked on top of one another as a starting material and welded to one another and reduced in thickness by roll welding.
  • the slabs are preferably ground on their surfaces which come into contact with one another, the slabs being expediently straightened by pre-shaping.
  • slabs are used that come from the same steel melt.
  • At least two packets are first formed from at least two each, and after the slab packs have been welded, each roll block is stacked on top of one another and rolled-welded to one another welded and reduced in thickness.
  • the method according to the invention is of particular importance with regard to quality and costs if continuous cast slabs are used as slabs.
  • the field of application for continuous casting slabs is significantly expanded, since the ratio of the thickness of the starting material, i. H. the slab thickness to the sheet thickness can be very small.
  • Continuous cast slabs provided the production conditions are selected correctly, have a perfect surface and interior quality. Furthermore, they have only a small segregation zone of low intensity. Continuous cast slabs are therefore practically free of internal cracks and poor in inclusions, so that they are particularly advantageous for the process according to the invention.
  • the slabs or rolling blocks which are stacked on top of one another in packages, are expediently sealed off by a welding frame, the package sealed with a welding frame being expediently evacuated prior to roll welding.
  • the package After the package has been built, the package is rolled down in several passes (indicated by the arrows 4) to a thickness of 150 mm using the hot rolling method.
  • the primary material, the continuous casting slabs 1, have a high degree of purity of non-metallic inclusions, so that after hot rolling there is a homogeneous material with a thickness of 150 mm. This is confirmed by ultrasonic testing.
  • the heavy plate 5 produced in this way can be produced much more cost-effectively than that in the usual way via a block casting.
  • the sheet to be produced is to have a very large thickness or if a larger number of slabs is required because of the desired degree of deformation, it is advantageous to form “subpackages” and to deform each of these subpackages by roll welding to form a billet and then the billets again to stack a "roll block package” on top of one another and to weld them to one another by roll welding, it being possible to start from any number of slabs or to continue working with any number of roll block packages.
