Definitions

  • the invention relates to an adjustable continuous casting mold for the production of continuous cast ingots of different dimensions, comprising a mold frame with a pair of opposite stationary side walls and a pair of opposite end walls, at least one end wall being slidably arranged, and each side and end wall having a first coolant chamber and a plurality with the first coolant chamber communicating with first coolant channels for applying coolant to the continuous casting material.
  • the invention further relates to a method for carrying out the continuous casting process with the mold according to the invention.
  • Continuous casting molds are used to pour liquid metal from a ladle or the like into a mold, it being possible to produce workpieces with a full or hollow cross section.
  • Such continuous casting devices for the production of ingots or bolts as primary material for their further processing by, for example, extrusion or rolling consist of a water-cooled mold, i.e. a mold which is usually open at the top, with parallel walls and an initially tightly closing but lowerable bottom, the mold walls usually being hollow and being cooled with water.
  • molten metal is poured at a predetermined speed onto a start-up floor that initially closes tightly with the mold frame.
  • the mold frame forms the vessel wall for the melt and must therefore be leakproof over its entire circumference.
  • the mold bottom is then lowered during the continuous casting, and at the same time so much metal melt is always refilled into the mold that the level of the melt in the mold remains constant.
  • the mold bottom is therefore lowered at a speed adapted to the pouring rate.
  • the mold frame serves on the one hand for shaping and on the other hand for heat dissipation from the melt. If the metal melt is poured into the mold, this melt solidifies rapidly on the walls and bottom of the mold, so that at least the outermost edge zone of the melt solidifies within the mold frame.
  • a coolant to the billet emerging from the mold, such as spraying the strand with water, the area near the surface of the strand emerging from the mold is further rapidly solidified, so that a bowl whose content is still liquid is formed.
  • the mold base In the case of the mold designed according to DE-OS 1 059 626, however, the mold base must always be adapted to the new bar cross section. In addition, the adjustment of the mold frame to the respective bar cross-sections requires a lot of time and usually leads to a longer interruption in the production line, which has an unfavorable effect on the production time and the production costs if only a few castings of a certain width are required.
  • FR Application No. 83 15766 which is disclosed under No. 2 552 692, describes a mold with a mold cross section that can be adjusted during the continuous casting process, this being accomplished by computer-controlled adjustment of the inclination of an adjustable end wall.
  • the computing effort for such a bar cross-section control is large, which requires the use of powerful computers.
  • the fixed edge zone of the ingot emerging from the mold in the mold area must withstand the total pressure of the continuous casting material above it at each location, the total pressure being the hydrostatic pressure of the continuous casting material melt and the pressure of the over your lying solidified casting material results. While in the case of stationary, vertical mold walls, the total pressure directed to the surface of the edge zone depends only on the hydrostatic pressure of the continuous casting material melt, the total pressure in the case of ingots emerging from the mold, which have a non-perpendicular edge zone, in addition to the hydrostatic pressure due to the perpendicular to the edge zone acting component of the solidified continuous cast material lying above it.
  • the Rate of adaptation of the mold cross-section to the desired ingot cross-section depends on the continuous casting material and on the thickness of the solidified edge zone.
  • the continuous casting process is preferably started with a starting cross-section which is smaller than the desired bar cross-section and which is then gradually adapted to the desired bar cross-section, resulting from the thin ingot edge zone formed within the mold usually a very low, maximum adaptation rate of the mold cross-section. This has a correspondingly negative effect, particularly in the case of a strongly changing bar cross section and leads to a large loss of material, since the bar part with a variable cross section is usually unsuitable for further processing.
  • the inventor has now set himself the task of creating an adjustable mold, which allows a quick bar cross-section adjustment and thus the very cost-effective production of rolled or pressed bars with different cross-sectional dimensions with one and the same mold.
  • the displaceable end walls have a second coolant chamber, and also a plurality of second coolant channels connected to the second coolant chamber for further application of coolant to the continuous casting material, the second coolant channels being arranged in such a way that the coolant emerging from the second coolant channels Seen in the flow direction of the continuous casting material, after the coolant emerging from the first coolant channels strikes the continuous casting material.
  • the first coolant chamber fulfills two functions: on the one hand it serves to cool the shaping part of the mold frame and thus for direct heat dissipation from the continuous casting material and on the other hand as a coolant supply for the coolant channels, the coolant being directed onto the surface of the continuous casting material emerging from the mold, thereby leading to the edge zone of the continuous cast ingot is cooled further.
  • the first function of the first coolant chamber on the one hand requires a thin wall thickness between the coolant chamber and the inner wall of the mold frame and, on the other hand, good thermal conductivity of the wall material.
  • the second coolant chamber essentially serves only to supply coolant to the second coolant channels.
  • the coolant flowing through the second coolant channels and striking the continuous casting material in the continuous casting material leads to a faster solidification in the region of the displaceable end walls or to the formation of a thicker, consolidated edge zone.
  • the resulting thicker edge zone resists a higher total pressure of the continuous casting material lying above it, so that the continuous casting mold designed according to the invention allows the mold cross section to be adapted more quickly to the desired ingot cross section; this is particularly the case with a cross section of the mold frame that increases during the continuous casting process.
  • the additional coolant applied to the continuous casting material by the second coolant channels is only necessary on the movable mold walls, since the primary cooling of the continuous casting material by the first coolant chamber and the first coolant channels creates a sufficiently thick edge zone in the area of the stationary, vertical mold walls to accommodate the hydrostatic pressure of the vertical Resist continuous casting material column lying above this edge zone. Accordingly, during the continuous casting process, the secondary coolant supply through the second coolant channels can be stopped, for example, after the desired ingot cross-section has been reached, so that the displaceable end walls of the mold according to the invention preferably have a valve for interrupting the coolant supply to the second coolant chamber or to the second coolant channels.
  • the mold cross section can be adapted to the required ingot cross section by a purely translational displacement of the displaceable end walls, so that no complex adjustment of the inclination angle of the end walls is necessary for setting the ingot cross section.
  • the ingots produced by continuous casting usually have somewhat concave side faces. This concavity of the ingot side surfaces is due to a shrinkage process taking place during the cooling of the melt and occurs in particular on the flat sides of long-shaped, rectangular rolling ingots.
  • the concave curvature of the ingot sidewalls resulting from the shrinking process depends, among other things, on their format, alloy and the casting speed. Typical values for the feed are 5 to 10 mm per side for rolled bars of the format 300 x 1000 mm made of a magnesium-containing aluminum alloy and at a casting speed of 5 to 8 cm per minute. Such deviations from the planarity of the surface are undesirable insofar as they occur during milling lead to an increase in waste and cause difficulties with the rolling of the bars when rolling.
  • the inner surfaces of the continuous casting mold are curved outwards in accordance with the degree of shrinkage.
  • the molten metal leaves the mold with the side surfaces curved outwards, which then become flat as a result of the shrinkage.
  • the first and second coolant channels are designed such that the coolant emerging from the second coolant channels, viewed in the flow direction of the continuous casting material, strikes the continuous casting material after the coolant emerging from the first coolant channels.
  • the first coolant channels are preferably designed in such a way that their longitudinal axes form an acute angle of 20 to 40 ° with the central axis of the mold cavity delimited by the mold frame.
  • the central axis of the mold cavity is understood to mean the central axis of the mold cavity which is parallel to the flow direction of the continuous casting material.
  • the longitudinal axes of the second coolant channels preferably form an angle of 60 to 85 ° with the central axis of the mold cavity.
  • the number of first coolant channels depends, among other things. on the size of the ingots to be produced, the continuous casting speed and the continuous casting material.
  • the side walls preferably contain 8 to 30 and the fixed end wall 5 to 25 first coolant channels.
  • the openings of the first coolant channels directed against the mold cavity are preferably all in the same cross-sectional plane of the mold.
  • the coolant channels are preferably arranged in such a way that the coolant is applied uniformly over the entire cross-section of the ingot.
  • the number of second coolant channels depends, among other things. on the length of the movable end wall or on the bar cross-section, on the continuous casting material and the speed at which the mold cross-section adapts to the desired bar cross-section.
  • the number of second coolant channels per displaceable end wall is preferably between 8 and 30.
  • the openings of the second coolant channels directed against the mold cavity are preferably all located on the same cross-sectional plane of the mold and are preferably arranged in such a way that the coolant is applied uniformly to the side faces of the ingot adjacent to the displaceable end walls.

It is essential that between the continuous casting material and the entire part of the mold frame that is mechanically directly exposed to the continuous casting material, i.e. a lubricant or lubricant is introduced into the shaping inner wall of the end and side walls directed against the mold cavity.

  • the front connection profile seen in the flow direction of the continuous casting material is referred to below as the first connection profile
  • the connection profile following the central part, which is seen in the flow direction of the continuous casting material is referred to as the second connection profile.
  • the middle part very preferably has an essentially U-shaped longitudinal section, so that by joining the middle part with the second connection profile, as seen in the direction of flow of the continuous casting material, a cavity is formed as the first coolant chamber.
  • the inner walls of the end and side walls directed against the mold cavity can, as a whole, enclose a cylindrical cavity, expediently a cavity with a square cross section.
  • the individual inner walls do not have to describe a one-piece surface lying parallel to the longitudinal axis of the mold. Rather, the mold cavity can be formed by a plurality of mold partial cavities arranged sequentially one after the other.
  • the cavity enclosed by the connection profiles of the front and side walls has, for example, a larger cross section than the cavity formed by the central parts of the front and side walls.
  • the cavity formed by the middle parts has a smaller cross-section and thus, due to the cooling effect of the inner wall, brings about the shaping of the continuous casting material.

  • Gearwheels in the form of single-stage or multi-stage gearwheels are preferably used. These allow slip-free transmission of the rotary motion of the drive shaft to the axle shaft (s) in a defined gear ratio.
  • cylindrical spur gears are suitable as gear drives.
  • the cylindrical gears can be straight, oblique, arrow-shaped (arrow gears), or helical (screw gears), as well as internally or externally toothed.
