  • ABSTRACT A method of controlling the cooling rate of narrow side walls of plate molds during continuous casting, wherein the narrow side walls are fixedly clamped between the wide side walls, prior to start of the casting the hollow casting compartment between the narrow side walls is provided with a casting taper which converges in the direction of travel of the cast strand or casting and which is accommodated to the quality of thesteel and the width of the strand.
  • the casting taper Prior to the start of the casting operation the casting taper is additionally adjusted to a reference value which corresponds to the contemplated casting speed and/or casting temperature, and upon deviation of the casting speed and- /or casting temperature during the casting operation the casting taper is changed in accordance with reference values corresponding to such fluctuating or changing casting parameters.
  • the present invention relates to a new and improved method of controlling the cooling rate of narrow side walls of plate molds during continuous casting, wherein the narrow side walls are fixedly clamped between wide side walls of the mold, prior to the start of the casting operation the hollow mold compartment between the narrow side walls is provided with a casting taper which converges in the direction of travel of the strand and which is accommodated to the quality of the cast metal, typically steel, and the width of the strand, and furthermore, the invention also pertains to a new and improved apparatus for the performance of the aforesaid method.
  • this particular field of technology is aware of an adjustable plate mold construction which, along with the adjustment of the narrow sides of the mold to different widths of the strand, simultaneously alters the casting taper of the hollow mold compartment between such walls according to a value of the contraction of the strand which is predetermined as a function of the width of the strand.
  • the adjusted casting taper or cone is only optimum for a small range of the casting speed and the casting temperature, i.e., contact of the solidified strand shell and thus the withdrawn quantity of heat is only optimum at such values.
  • the shrinkage or contraction Upon changing the casting speed and/or the casting temperature the shrinkage or contraction also alters, and consequently, there results non-uniform cooling and solidification of the shell or skin of the strand. These irregularities lead to fissures and ruptures and increase the breakout danger and wear of the mold.
  • a further proposal which has been advanced in the an concerns a plate mold which is subdivided into two components transversely with regard to the direction of travel of the strand.
  • the upper portion does not possess any casting taper and the walls of the lower portion are resiliently urged against the strand surface. Gaps are provided between the walls arranged at the lower portion which neighbor one another, rendering possible free movement of the walls without mutual hindrance.
  • the resilient or spring force which acts against such walls must be capable, on the one hand, of withstanding the force generated by the ferrostatic pressure and, on the other hand, the resilient force must not deform the strand shell which is still thin.
  • This prior art equipment is unsuitable for casting operations where there prevail fluctuating casting parameters, such as casting speed and casting temperature and the like, because the resilient or spring force is not adjustable to different thicknesses or different strengths of the shell. Moreover, walls which are pressed against one another by such springs tend to wear rapidly. Additionally, such narrow side walls of the mold cannot be fixedly clamped between the wide side walls of the mold, so that at the region of the level of the molten bath there is precluded the use of such equipment.
  • Another and more specific object of the invention aims at providing an improved method of carrying out continuous casting operations while providing optimum and uniform cooling within the mold during changes in the casting parameters, in particular the casting speed and the casting temperature.
  • Another object of the invention is directed at rendering possible continuous casting operations, particularly at high output continuous casting installations, with large differences in the casting speed and while providing improved quality in the cast strand and reducing the danger of metal breakout.
  • the casting taper is additionally adjusted to a reference value corresponding to the prescribed casting speed and/or casting temperature, and upon deviation of the casting speed and/or the casting temperature during the casting operation the casting taper is altered in accordance with predetermined reference values which produce a desired or optimum cooling effect corresponding to such fluctuating casting parameters.
  • the accommodation of the casting taper during or shortly after the change of the casting speed, the casting temperature or other casting parameters which influence solidification of the strand can be carried out according to different techniques.
  • Such optimum reference value as a general rule, is strived for in respect of uniform solidification of the shell of the strand.
  • the casting taper can be accommodated to predetermined reference values corresponding to the altered casting speed and/or the altered casting temperature. Reference values for the casting taper K in the continuous casting art are normally expressed in terms of percent per meter per m).
  • the cooling rate of the narrow side walls of the mold can be continuously measured, such measurement values compared with those reference cooling rate values corresponding to the actual-casting speed and/or the actual-casting temperature and upon deviation between the referenceand actualcooling rate values adjusting the casting taper until reaching the reference cooling rate.
  • the cooling rate of the narrow side walls of the mold not only is influenced by the casting speed and the casting temperature, but also by the flow at the liquid casting head, the nature and quantity of the casting powder slag and by bending moments produced by virtue of irregular .cooling of the strand.
  • a further advantageous method for accommodating the casting taper during change of a casting parameter influencing the cooling rate of the. narrow side walls of the mold can be realized according to the invention if the specific cooling rate of the narrowand the wide side walls are continuously measured, the measurement values of the narrowand wide side walls mutually compared and the specific actual-cooling rate ratio between such walls discriminated with the predetermined specific reference-cooling rate ratio and. upon deviation between thespecific reference-' and actual-cooling rate ratio accommodating the casting taper until reaching the specific reference-cooling rate ratio.
  • the withdrawal of heat at the strand and the growth of the strand shell is controlled as a function of the sum of the casting parameters which are responsible therefor.
  • all casting parameters and also all uncontrollable influencing factors, such as expansion within the mold or the bending moments at the strand generated by the secondary cooling and so forth, are taken into account.
  • the reference taper for given casting parameters, can be advantageously ascertained during the casting operation if the cooling rate of the narrow side walls of the mold is continuously measured, during change of the casting taper K there is differentiated the deviation of the cooling rate AQ (Kcal/cm sec) according to the deviation of the taper AK (%/m) and the reference taper associated with the reference cooling rate value determined from the curve characteristic.
  • the reference cooling rate value and the reference taper is located at the transition region between the ascending and horizontal branch of the function curve Q/ Q-
  • the reference cooling rate value and the reference taper is located at the transition region between the ascending and horizontal branch of the function curve Q/ Q-
  • the mold is designed such that the pivotable connection associated with the plates for the adjustment of the taper is formed by a shaft extending parallel to the narrow side walls of the mold, and which shaft is located near to a plane formed by the outlet of the mold.
  • the force for adjusting the casting taper during the casting operation can be maintained relatively small and there can be avoided scratching of the copper plates of the wide side walls of the mold if, according to an additional facet of the invention, the force for fixedly clamping the narrow side walls during the adjustment operation is reduced to about twice the value of the counter-force which acts by virtue of the ferrostatic pressure and after the adjustment again increased to the value which prevailed prior to the adjustment.
  • the invention concerned with the aforementioned method aspects, but as already heretofore mentioned, also deals with a new and improved construction of apparatus for the performance thereof, and specifically a plate mold wherein the narrow side walls of the mold which can be fixedly clamped between the wide side walls of the mold are equipped with devices for adjusting the hollow mold compartment to difierent strand dimensions and with devices for adjusting the casting taper.
  • a plate which is pivotably connected, and that alternately the one of both adjustment devices is attached to the support frame and. to the plate and the other of the adjustment devices is connected to the plate and the narrow side wall.
  • the clamping force of the wide side walls can remain unchanged during the accommodation of the casting taper to the different casting parameters and at the same time there can be avoided wear of the copper plates at the wide side walls of the mold if, according to a further aspect of the invention, the taper adjustment device is attached to the plate and at the narrow side wall and the apparatus for adjusting the hollow mold compartment to different strand dimensions is attached to the plate and at the carrier or support frame, wherein the plate connected by the shaft with the narrow side wall can be clamped between the wide side walls, and if the size of the plate which determines the width of the hollow mold compartment is greater up to two millimeters in relation to the narrow side wall.
  • a further advantageous mold construction of the invention is manifested by the features that the taper adjustment device is secured to the plate and at the carrier frame, the device for adjusting the hollow mold compartment to different strand dimensions is secured to the plate and to the narrow side wall, and that the plate together with the narrow side wall is pivotable about the shaft arranged at the carrier frame.
