Definitions

  • ABSTRACT Continuous casting of metal in which molten metal contacts a cooled axial mold wall surface to form a skin increasing in thickness in a direction toward a discharge opening of the mold. At least a portion of the last-mentioned mold surface increases in crosssectional size over its length in the direction of the discharge opening.
  • the casting is relatively withdrawn from the mold at an average casting rate during the casting operation and also the casting and the mold are oscillated relatively to one another in a particular manner. The maximum velocity capability of oscillation is greater than the casting rate.
  • PATENTED f3 857. 437 sum 3 [1F 5 METHOD AND APPARATUS FOR CONTINUOUSLY CASTING METALS BACKGROUND OF THE INVENTION 1.
  • This invention relates to a method and apparatus for continuous casting of metals, and relates more particularly to such method and apparatus which is improved to provide increased casting rates and smoother surface finish of castings.
  • Hot tearing results from resistance between the mold and thin solidifying skin upon movement of the casting relatively to the mold such as to create tensile stresses in the skin greater than the tensile strength of the skin. Hot tearing may also result in a phenomenon known as a breakout such as to cause cessation of the casting operation.
  • the mold may have a tubular internal axial surface portion provided with a taper opening in the casting direction to facilitate release of the casting by the mold on withdrawal of the casting, the taper being located adjoining a molten metal delivery nozzle.
  • Oscillating molds have been known to have a similar taper but in an opposite direction and, at least in part, for approximating the cross sectional shrinkage of the casting on progressive longitudinal cooling of the casting within the mold in the casting direction.
  • the stationary mold of aforementioned U.S. Pat. No. 3,642,058 also is provided with a tapered surface portion of the lastmentioned type, located adjoining the first-mentioned taper and extending therefrom in the casting direction.
  • the present invention includes the use of an oscillating mold in such casting of metals, which mold has a particular internal configuration throughout at least a portion thereof which, when the mold is oscillated, coacts with the casting forming within the mold to minimize hot tearing of the casting skin and maximize heat transfer from the casting.
  • the invention contemplates improvement in techniques of continuous casting of metals, applicable to vertical and horizontal casting operations and casting operations utilizing molds of the open-ended type and of the type having a closed end or a plug. It contemplates improved cooperation between a molten metal delivery nozzle and an open-ended mold utilized in continuous casting of metals.
  • One object of the invention is to increase casting rates by improved cooling of a casting within and by a mold while at the same time improving the surface characteristics of such castings by effectively reducing hot tearing within a mold. Moreover the invention contemplates in this respect improved structure for healing any hot tearing.
  • Yet another object is to provide contact and axial compression between the mold and the thin solidifying skin of the casting on each movement of the mold in the casting direction during oscillation to repair any hot tearing and enhance heat transfer from the casting, while avoiding longitudinal tension on such skin such as to cause hot tearing on movement of the mold in the opposite direction.
  • Still another object is to allow the resistance of the casting to movement of the mold in the casting direction to slow the mold from a greater velocity to approximately the casting rate or velocity, and maintain substantially constant the axial pressure of the mold on the casting throughout a portion of the movement of the mold in the casting direction.
  • FIG. 1 is a fragmentary schematic view of apparatus for continuous casting of metals, embodying the invention
  • FIG. 2 is an enlarged broken and fragmentary view of the mold in cross section which may be employed in such apparatus and illustrates a particular internal surface configuration of a portion of the mold, omitting details of the water jacketing;
  • FIG. 3 is an enlarged median sectional view of the mold of FIG. I illustrating the latter in operation, omitting certain structural details of FIG. 1;
  • FIG. 4 is a fragmentary diagrammatic view illustrating certain parts of the mold oscillating mechanism in certain relative positions thereof during a typical oscillation cycle
  • FIG. 5 is a view similar to FIG. 4 but showing the parts in different relative positions during such an oscillation cycle.
  • casting apparatus which is oriented horizontally for horizontal casting of metals but which may be used in a vertical orientation for a vertical casting if desired.
  • a tundish indicated generally at It
  • a tundish is provided for receipt, as from a non-illustrated ladle of molten metal to form a reservoir for such molten metal, having a refractory lining element 12 and a molten metal delivery tube or nozzle 14 also of a refractory material.
  • the discharge end of the nozzle 14 is surrounded by a copper collar 16 which is secured to the tundish as by being bolted thereto as at 18.
  • the collar is provided with a passageway 20 for circulation therethrough of a coolant such as water.
  • a sleeve 22 formed of a heatresistance material such as boron nitride, for example, and which may have the cross-sectional configuration shown in FIG. 3.
  • the sleeve 22 may be held in axially fixed relation to the collar 16 by suitable keys 24 and by abutment with the collar 16 in the manner shown.
  • the sleeve 22 forms a continuation of the nozzle I4 for the discharge of molten metal.
  • the nozzle construction thus far described cooperates in this illustrated form with an open-ended mold 26 having in the wall structure thereof a passage 28 for the circulation of a coolant such as water therethrough and which mold is movable axially on oscillation with reference to the nozzle structure.
  • the mold is slidingly supported on support element 30.
  • the tundish may be supported in a conventional manner not shown.
  • the cavity of the mold 26 has the desired cross-sectional shape of the casting to be produced. Suitable bearings 32 are interposed between the slidable mold 26 and the collar 16.
  • the forward end portion of the sleeve 22 of the nozzle structure which extends forwardly beyond the collar, has an outer peripheral surface 34 which is inclined in the manner shown to provide a cam surface for spring-biased sealing segments 36 interposed between the sleeve 22 and the mold 26 and spaced forwardly of the collar 16.
  • the sealing segments 36 which are formed of a heat-resistant heat-resistant such as boron nitride or graphite coact internally with the mold and with one another around the interior of the mold for sealing purposes and each has a surface of complemental shape to the cam surface 34 for sliding engagement therewith so that the seal may move generally inwardly toward and outwardly from the center line of the mold.
  • a plurality of compression springs are provided urging the sealing segments 36 outwardly against the mold, the springs being indicated at 38.
  • Each spring 38 may have one end thereof socketed in the collar 16 and the other end thereof socketed in the corresponding sealing segment 36.
  • the desired and selected maximum distance of oscillation of the mold in engagement with the seals 36 is represented by the solid line position and the broken line position of the mold shown in FIG. 3.
  • the seals 36 are located in the forward extremity of the tube or nozzle structure and in the positions shown form a continuation of the surface 40 of the sleeve 22. Owing to the construction and arrangement of the seals 36, the seals, which are spring biased, have a considerable forward and rearward component of movement capability on the cam surface 34 of the sleeve 22. The seals prevent the passage of molten metal rearwardly therepast while allowing hot gases from molten metal to pass and escape in the last-mentioned direction.
  • molten metal 42 from the tundish 10 exits therefrom into the mold 26 through the above-described nozzle structure in a manner such that the molten metal contacts the cooled internal axial surface of the mold and solidifies thereagainst to form a skin 44 which, as the casting operation proceeds, increases in thickness in the casting direction which is to the right as viewed in FIG. 3.
  • the casting is indicated generally at 46.
  • the usual dummy bar inserted into the mold through the open end thereof remote from the tundish l0 and on which the molten metal solidifies, is withdrawn by the usual pinch rollers to commence the issuance of the casting from the mold.
  • the usual jets of cooling water are impinged on the casting along a portion of its length as it leaves the mold to solidify the casting further.
  • the dummy bar, the pinch rollers and the water jets are not shown.
  • the internal axial surface of the tubular wall structure of the mold is provided with an axial taper opening in the casting direction and located at least within the area of the internal axial surface which is exposed or in contact with the casting skin 44 where it is relatively thin and has little relative tensile strength, that is in an area where the skin is relatively newly formed.
  • the last-mentioned taper indicated at 48, extends from the end of the mold which when the mold is assembled on the abovedescribed nozzle structure is closest to the tundish 10.
  • the taper 48 extends in the casting direction beyond the nozzle structure, and the aforementioned seals 36 cooperate with the surface portion 48.
  • the taper 48 terminate in the casting direction a distance short of the discharge end of the mold, so that the internal axial surface of the mold may have forwardly and adjoining the taper 48 an axial surface portion which is untapered or which may have a taper converging in thhe casting the or a combination of such surface portions wherein the converging taper, not shown, is downstream of the untapered surface portion indicated at 50, to approximate the cross sectional shrinkage of the casting in the casting direction for better heat transfer from the casting in this area of the casting where the casting skin is relatively thick and strong as compared to the aforementioned thin portion of the skin 44.
  • the invention and the aforementioned configuration of the internal axial surface portion of the mold is applicable to the casting of metals utilizing a mold of the type having a closed end or mold cavity bottom as illustrated and described in my allowed co-pending U.S. patent application, Ser. No. 268,977, filed July 5, 1974, now U.S. Pat. No. 3,814,166, and in my U.S. Pat. No. 3,517,725 issued June 30, 1970, wherein the casting direction is in the direction toward the tundish from the mold.
  • the mold and the tundish are separated during a casting operation forming a casting having a solidified skin or shell around a molten core, and the mold and the casting are oscillated relatively to one another.
  • Molten metal flowing through the core of the casting and entering the mold cavity, enters the cavity adjacent the bottom thereof and forms a thin axial skin near the mold bottom which skin increases in thickness in the casting direction as the casting proceeds.
  • the casting is withdrawn from the mold by solidification on a starting device supported on the tundish.
  • the molten metal inlet of the mold is considered as distinct and separate from the open discharge end of the mold.
  • the molten metal inlet is considered as being adjacent the bottom of the mold within the mold cavity.
  • the mold has a maximum velocity capability in the casting or forward direction which is greater than the casting rate.
  • the mold velocity in the forward direction is the sum of the casting rate, the component due to deformation of the casting by the mold and longitudinal shrinkage of the casting.
  • Another feature of the mold oscillation is that the casting, during such forward movement, slows the mold to approximately the casting rate or velocity by the resistance of the skin of the casting to movement of the mold.
  • Various devices or mechanisms such as an air cylinder may be utilized for accomplishment of these features. For example, limit switches may be utilized to fix the length of the stroke.
  • the presently preferred oscillation mechanism utilizes, instead of an air cylinder, a driver for the mold which is in the form of a timed cam or crank.
  • the maximum compressive load of the mold on the skin of the casting lengthwise of the latter is predetermined during any portion of a cast and may be adjusted during the cast.
  • such compressive loading on the skin may be maintained substantially constant throughout a portion of the forward stroke of the mold.
  • FIG. 1 The general organization of the drive for oscillating the mold is shown diagrammatically in FIG. 1, wherein a cam or crankwheel 52 is driven through suitable reduction gearing from a prime mover 54.
  • a link indicated generally at 56, self-adjusting as to length, interconnects the cam or crankwheel 52 with a flange 58 in fixed relation to the mold 26.
  • the driving wheel 52 generates a sine wave but the wheel 52 may be so constructed as to generate other wave forms.
  • one end of the link 56 is pivoted (FIGS. 4 and 5) eccentrically to the wheel 52 as at 60.
  • the other end of the link 56 is pivoted to the flange 58 of the mold as at 62.
  • the motor 54 which is of the adjustable speed type, drives the wheel 52 at a predetermined constant speed.
  • the link 56 includes a pneumatic cylinder 64 having at one end thereof a rod extension 66 fixed to the cylinder 64.
  • the distal end of the rod 66 has the aforementioned pivot connection 60 to the wheel 52.
  • the link 56 also includes a driven member in the form of piston 68 in the cylinder 64, provided with a piston rod 70 having the aforementioned pivot connection 62 with the flange 58 of the mold.
  • a source of compressed gas not shown, has an output 72 to a pressure regulator 74 and a gas line 76 connects the cylinder 64 and the regulator 74.
  • the pressure regulator 74 which is of a conventional type, not only governs the input to the cylinder 64 through the line 76 but has the function of relieving pressure in the cylinder 64 through the line 76 to maintain a con stant pressure therein regardless of the position of the piston 68 in the cylinder.
  • gas line 76 is a twoway gas line.
  • the cylinder 64 and' piston 68 form a constant-rate air spring, the pressure of which is adjustable by the regulator 74. It will be understood that the torque of the wheel 52 is greater than the maximum anticipated desired loading of the air spring.
  • the load of the air spring represents the maximum load with which the mold 26 is moved in the forward direction, and may be changed during the casting operation to accommodate changing thermal conditions in the mold if desired.
  • the compressive loading of the mold on the forward stroke is always sufficient to maintain intimate contact between the mold taper 48 and the casting for heat transfer from the latter.
  • the load on the mold may also be adjusted in accordance with the particular metal being cast.
  • the casting skin may be relatively thin and weak and require less of a load than during a later part of the casting operation as when the temperature of the metal being poured has decreased by the amount of superheat lost as during the pouring of molten metal from a ladle into the tundish over a period of time, say 1 hour for example.
  • the molten metal may solidify faster in the formation of the casting skin.
  • the speed of the forward oscillation stroke is in part always greater per unit length than the casting rate at the same unit length.
  • the difference may not be significant, but if operating conditions require it, the difference may be substantial.
  • the speed or rate of withdrawal of the casting from the mold is adjustable and, as previously indicated the speed of the driving wheel 52 may be adjusted by adjusting the speed of the motor 54.
  • the proportional difference between the forward oscillation stroke of the mold and the withdrawal rate of the casting is maintained throughout a casting operation. That is, when the casting speed is increased during a casting operation, the speed of the driving wheel 52 is increased correspondingly.
  • the compressive load of the mold on the casting is through the taper &8 of the mold bearing on the skin of the casting during the forward stroke, and the load is relieved on the rearward stroke.
  • the cam or crankwheel 52 rotates in the direction of the arrow of FIGS. 4 and 5, and at the instant in time in which the pivot 60 is in the position of FIG. 4, the mold is at rest, the mold having been returned to the fullest extent of its rearward movement from a forward position by the pull of the cylinder 64 on the piston 68.
  • the mold accelerates in the forward direction and catches up to the speed of the casting rate. It may pass the speed of the casting rate on acceleration, provided that the skin of the casting in contact with the taper 48 of the mold is sufficiently soft to be deformed by the mold, as the pivot 60 approaches the position of FIG. 5 from the position of FIG. 4.
  • the mold may travel to its fullest extent in a forward direction, with the piston 68 remaining in the cylinder-bottoming position of FIG. 4.
  • the resistance of the casting skin to movement of the mold in a forward direction is usually such as to be greater than the compressive loading on the casting dictated by the air pressure in the cylinder 64, and this condition is shown in FIG. 5.
  • the resistance of the casting to the mold movement has slowed the velocity of the mold to approximately that of the casting rate, and accordingly the piston 68 is displaced to the extent shown by way of example in FIG. 5.
  • the compressive loading on the casting remains substantially constant through a portion of the forward mold stroke.
  • the mold taper 48 may remain in contact with the casting for a period of time after the velocity component of the cam on the forward stroke has slowed to a speed below that of the casting, as the driving wheel 52 rotates from the angular position of FIG. 5 through a further angle in a clockwise direction thereof.
  • the action of the air spring when the piston 68 has been displaced in the cylinder 64 by resistance of the casting to mold movement, is such as to attempt to effect the maximum forward stroke of the mold.
  • the length of the forward stroke during an oscillation cycle is dependent upon the relative velocities of the casting and the mold and the resistance of the casting to the mold movement.
  • the casting through its resistance to mold movement on the forward stroke, itself changes the character of mold oscillation during a casting operation such as average mold velocity on the last-mentioned stroke, effectively tending to achieve a character of mold oscillation suitable to the then prevailing particular conditions of the casting operation including thermal conditions.
  • the maximum compressive loading of the mold on the casting will remain constant, provided that the regulated air pressure in the cylinder 64 is not adjusted by the regulator 74.
  • a process of continuously casting an elongated metal article utilizing a mold having a molten metal inlet, a cooled tubular wall structure and an open outlet end for the issuance of a casting therefrom in at least partially solidified form, and comprising the steps of:
  • said mold defines a mold cavity having a closed end remote from said metal source forming a bottom of said cavity, said open outlet end of said mold opening toward said metal source, said mold and said source being separated during relative withdrawal of the casting from the mold, the casting direction being from said mold toward said source, the casting skin forming a solidified shell around a molten core through which core molten metal flows to said mold from said source, said molten metal being introduced into said mold cavity adjacent the bottom thereof.
