Definitions

  • This invention relates to impact pads used in steel-making, especially to tundish impact pads adapted to reduce turbulence and bath surface disruption generated by a molten steel ladle stream fed into a continuous caster tundish.
  • the invention further relates to tundishes and apparatus including the impact pads, and methods of using the impact pads, tundishes, and apparatus.
  • a steel caster is an apparatus for carrying out continuous casting, also referred to in the art as strand casting.
  • Continuous casting involves transferring molten steel from a steelmaking furnace into a ladle. From the ladle, the molten steel is fed through a shroud of the ladle (also referred to as a ladle shroud) extending into a container or vessel referred to as a tundish.
  • the molten steel typically is fed at a continuous or semi-continuous liquid flow into a molten steel bath contained in the tundish.
  • the tundish typically acts as a reservoir from which the molten steel may be fed, without interruption or unwanted downtime, into caster molds.
  • a protective slag cover/layer or "flux" is allowed to form at the surface of the molten steel bath.
  • Surface requirements and cleanliness standards of modern high quality steel products allow for very low tolerances of impurities and chemical changes. Impurities and chemical changes often are the result of turbulence created by the incoming ladle stream of molten steel fed into the tundish.
  • Certain tundish designs for receiving liquid steel from the ladle shroud lead to unfavorable fluid flow conditions, such as turbulence, inside the tundish and promote high free surface flow activities.
  • the fluid flow generated by an incoming ladle stream may be reflected from the flat tundish floor and sidewalls toward the surface of the liquid steel. This generated fluid flow causes a turbulent boiling action, extensive wave motion, and splashing at the surface of the steel bath.
  • Fig. 10 illustrates a longitudinal cross section of a single strand tundish 1 having an asymmetrical fluid flow 9a.
  • the ladle shroud 7 is shown adjacent end wall 3 opposite a well block (not shown in Figs. 10 and 11).
  • Water flow-model studies have shown that the fluid flow, generated by an incoming ladle stream 8 from the ladle shroud 7, is reflected from the flat tundish floor 4 in an upward direction toward the surface of the liquid steel. If this fluid flow is restricted by the tundish walls 2 and 3, the restricted fluid flow is forced upward along the surface of such walls 2, 3.
  • This upward flow follows a circular path 9c, and creates an upward surge along the face of the end wall 3, and a downward flow around a ladle shroud 7.
  • the upward surge of the circular flow 9c causes excessive turbulence at the surface of the bath.
  • These high free surface activities in the tundish give rise to a phenomenon called "open-eye,” whereby the protective slag cover 6 on top of the steel bath is broken.
  • the broken slag cover 6 exposes the liquid steel to the surrounding atmosphere and sets up conditions conducive to altering the chemistry of the steel bath and creating inclusions in the steel bath.
  • the chemical changes typically involve loss of aluminum from the bath and/or absorption of oxygen and nitrogen into the steel bath and consequent surface re-oxidation.
  • Re -oxidation and other undesired reactions can introduce, for example, excess alumina, manganese sulfide, and calcium sulfide into the steel bath. Additionally, the downward flow around the ladle shroud 7 generates shear and vortices, and entraps and pulls broken particles 10 from the broken flux cover 6 down into the liquid steel bath. These broken particles 10 eventually are discharged from the tundish with the molten steel and create inclusions within the finished steel product.
  • a tundish impact pad features a base having a base surface with a conical impact surface area that establishes an apex, a sidewall, and a top wall extending inwardly relative to the sidewall to terminate an inner edge establishing a mouth opening spaced above and centered relative to the apex.
  • the top wall includes a lip sloping radially inwardly and downwardly towards the conical impact surface.
  • a second aspect of the invention provides an apparatus featuring a continuous caster tundish for containing a reservoir of molten metal having fluid flow generated by an incoming ladle stream, and a tundish impact pad in the continuous caster tundish.
  • the tundish impact pad includes a base having a base surface with a conical impact surface area establishing an apex, a sidewall, and a top wall extending inwardly relative to the sidewall to terminate at an inner edge establishing a mouth opening spaced above and centered relative to the apex.
  • the top wall includes a lip sloping radially inwardly and downwardly towards the conical impact surface.
  • a third aspect of the invention provides a strand casting method or molten steel processing method in which an incoming ladle stream of molten liquid steel is fed into a continuous caster tundish and impacted against a conical impact surface area of the tundish impact pad before being allowed to flow through a mouth opening of the tundish impact pad and into a tundish reservoir.
  • the tundish impact pad includes a base having a base surface, a sidewall, and a top wall extending inwardly relative to the sidewall to terminate at an inner edge establishing the mouth opening spaced above and centered relative to an apex of the conical impact surface area.
  • the top wall includes a lip sloping radially inwardly and downwardly towards the conical impact surface.
  • the top wall of the tundish impact pad features a lower surface that, collectively with the base surface and a continuous inner surface of the sidewall, establish a continuous annular chamber configured to reduce turbulence of an incoming ladle stream of molten liquid steel.
  • the conical impact surface area has an axis, passing through the apex, about which the conical impact surface area has rotational symmetry.
  • the conical impact surface area has a linear profile.
  • the conical impact surface area has a cone angle, measured from a horizontal plane in which an outer perimeter of the conical impact surface area lies to an oblique plane in which the conical impact surface area lies, in a range of about 15 degrees to about 25 degrees.
  • the lip has a downward lip angle, measured from a horizontal plane to a lower surface of the lip, in a range of about 20 degrees to about 25 degrees.
  • the continuous annular chamber has a radius of curvature of about 30 mm.
  • protuberances for example hemispherical protuberances, are distributed about a lower surface area of the lip.

  • a tundish for a strand caster in accordance with an exemplary embodiment is generally designated by reference numeral 10 in Figs. 1 and 2. Although a single-strand caster is shown therein, it should be understood that embodiments of the present invention may be practiced in connection with double-strand and other multiple-strand casters.

  • a tundish impact pad 20 is located in the reservoir 18, for example, closer to the end wall 12 than to the end wall 14.
  • Positioned above the tundish impact pad 20 is the lower part of a ladle shroud 22 for introducing an incoming ladle stream 24 (Fig. 7) of molten steel into the impact pad 20.
  • the ladle shroud 22 is shown penetrating through the top of the molten steel bath, with the end of the ladle shroud 22 spaced above and centered coaxially with the tundish impact pad 20.
  • the flow of molten steel and the structure and function of impact pad 20 are discussed in further detail below.
  • the tundish 10 further includes a weir 26 dividing the tundish 10 into right and left (first and second) compartments 18a and 18b, respectively, with the impact pad 20 in the right compartment 18a on the tundish floor 16 in Figs. 1 and 2.

  • the annular base surface area 44 may be at least partially flat and lie in a horizontal plane that is parallel to the bottom surface 40a of the base 40.
  • the tundish impact pad 20 further includes a sidewall 50 having a sidewall inner surface 52 that continuous ly/endlessly circles on itself to appear as an annulus when viewed from above, as in Fig. 4.
  • the sidewall 50 is shown having uniform thickness over its entire 360 degrees.
  • the sidewall inner surface 52 is positioned concentrically outside of and generally perpendicular to the annular base surface area 44.
  • the sidewall inner surface 52 includes curved transition areas 54, 56 at its bottom and top, respectively.
  • the curved transition areas 54, 56 may be symmetrical to one another.

  • the conical impact surface area 42, the annular base surface area 44, the continuous sidewall inner surface 52, the curved transition surface areas 54, 56, and the lower surface areas 60a, 66a collectively establish a continuous annular chamber about axis Az that may be in the form of a torus.
  • liquid steel is introduced into the tundish 10 through the shroud or sprue 22 as the incoming ladle stream 24. It has been found that the ratio (D j /D m ) of the diameter D j of the inner diameter of the shroud 22 to the diameter D m of the mouth opening 64 in a range of about 0.3 to about 0.4 provides particularly good results.
  • the ladle shroud 22 and the mouth opening 64 are coaxially aligned with one another in the exemplary embodiment.
  • the design of the exemplary embodiments described herein causes the incoming ladle stream 24 to impact against the conical impact surface area 42, which redirects the stream 24 radially outward towards the lower transition portion 54 and the sidewall inner surface 52.
  • the shape of the continuous annular chamber forces the molten steel flow into a reversed direction back towards the incoming ladle stream 24 to reduce the turbulence and dissipate the energy of the molten steel before it flows from the impact pad 10.

  • the molten steel exits the mouth opening 64 into the first compartment 18a.
  • the continuous inflow of the incoming ladle stream and removal of molten steel through the outlet 34 causes the molten steel in compartment 18a to flow towards the weir 26 and through the weir passage 26a. After passing through the weir passage 28, the molten steel flows over the dam 30 and/or through the cylindrical passages 30a before being discharged through the output 34.
  • the conical impact surface area 42 has a cone angle ⁇ (Fig. 5), measured from a horizontal plane in which the outer perimeter 48 lies to an oblique plane in which the conical impact surface area 42 lies, in a range of about 15 degrees to about 25 degrees.

  • the protuberances 80 may be uniformly distributed, such as in a matrix pattern, or distributed randomly or otherwise.
  • the outer surfaces of the protuberances 80 have a hemispherical shape. However, the protuberances 80 may undertake alternative shapes.
