Definitions

  • the invention relates to a thin strip caster including a pair opposite and approximately equal executed casting rolls, in turn form a funnel for receiving the molten steel by means of side seals.
  • thin-strip casters in particular two-roll casters, for the production of warm broadband in the usual width range of about 800 up to 1,400 mm and thickness range of about 2 to 5 mm, using casting rolls with Constant diameter and variable bale lengths are used as the Bandwidth is essentially determined by the bale length of the same.
  • the object of the invention is to improve the performance of existing thin-strip casters, which may already be operating in their marginal areas, with low mechanical engineering use and reasonable capital expenditure to increase, d. h.,
  • the object in connection with the features in the preamble of claim 1 achieved in that the thin-strip caster a plurality associated with each other interchangeable pairs of casting rolls, in Depending on the bandwidths to be cast "B” different casting rolls diameter Have "D".
  • each pair of casting rolls one Bale length defined by the bandwidth "B” and a defined casting roll diameter "D" on, with the product of the bale length and the casting roll diameter "D" of the casting rolls of all interchangeable pairs of Casting rolls is approximately equal.
  • An expedient development of the invention provides that the pairs of Casting rolls are each pre-installed in a removable frame.
  • the proposed thin-strip casting plant has with regard to known systems the main advantage that they are consistent without great technical effort Production of thin strip in every usual width range and thus one economic utilization of the upstream steelworks guaranteed.
  • FIG. 1a and 1b show a thin-strip caster 1 in the form of a known Zweirollen-casting plant, which in turn has a pair of opposing and approximately equal executed casting rolls 2, with a certain predetermined bale length, the approximately the bandwidth "B” corresponds, and a certain predetermined casting roll diameter "D" are provided.
  • the casting rolls 2 form a funnel 5.
  • This funnel 5 is used to hold the molten steel 6, which in turn is continuously provided by a upstream, not shown steelworks via an intermediate container 7 with so-called dip tube 8.
  • the molten steel 6 is filled into the funnel 5 formed by the casting rolls 2 and the side seals 3 up to a specific bath level 9, the height of which is also referred to as the solidification length "I” and defined by the bath level angle " ⁇ ".
  • the thin strip 12 leaves the thin strip caster 1 with the casting speed "V", which in turn corresponds to the peripheral speed of the casting rolls 2.
  • the casting speed is "v" of a thin strip caster 1 proportional to the casting roll diameter "D” and vice versa proportional to the strip thickness "d".
  • the casting roll 2a and 2b show in side view and plan view in comparison on the left side the casting roll 2 of a pair of casting rolls 2 for the production of a wide and right side the casting roll 2 of a pair of casting rolls 2 for the production of a narrow thin strip 12, since known the bale length the casting rolls 2 is defined or determined by the selected bandwidth "B". Furthermore, the casting roll 2 drawn on the left side for wide thin strip 12 has a smaller casting roll diameter "D" than the casting roll 2 drawn on the right side.
  • the invention will be illustrated by way of example even more clearly.
  • a miniature smelter for hot broadband with electric steel plant and thin strip casting plant 1 for approx. 500,000 t annual output in the width range of 800 to 1400 mm bandwidth "B” a steelworks with approx. 90 t hourly output and a thin strip Caster 1 with a casting roll diameter "D" of about 1.2 m are provided.
  • the thin-strip casting plant With a selected belt width "B" of 1,400 mm and the aforementioned casting roll diameter "D" of 1.2 m, the thin-strip casting plant also has an hourly output of 90 t.
  • the respective pairs of casting rolls 2 can be preinstalled in a removable frame 13 be, in turn, on a non-illustrated basic framework of the thin-strip casting machine 1 fixed, but detachable, is arranged.
  • This change frame 13 can furthermore have the same external dimensions for all dimensions of the casting rolls 2 used (FIG. 2 b).
  • the removable frame 13 also carries known Anstellrahmen 14 for the bearings 15 of the casting rolls 2, for example by means of hydraulic or pneumatically actuated adjusting cylinder 16 to the desired strip thickness "d" can be hired.
  • the brackets 4 not shown in Fig. 2a and 2b are provided for the known side seals 3 of the pairs of casting rolls 2.
  • these side seals 3 are known to be formed by an outer frame 18 which is filled with a refractory mass 19 ( Figures 3 and 4).
  • a refractory mass 19 are on both sides of the casting rolls 2 each deposits 20 made of special ceramic, such as boron nitride, embedded, which envelop the lying below the bath level 9 circumferential paths of the casting rolls 2.
  • removable frame 13 it is recommended that two removable frame 13 to provide, one of which with a corresponding pair of casting rolls 2 in Use is and the other with a corresponding pair of casting rolls 2 and new Side seals 3 is prepared for the next change.
