- ABSTRACT A method of, and apparatus for, the introduction of steel into the liquid metal pool of a continuous casting mold of a continuous casting installation, wherein a casting jet which is enclosed at its periphery at all sides is guided beneath the level of the molten bath'of the liquid metal pool in the continuous casting mold and thereafter deflected out of its original position.
- the casting jet is guided substantially immediately after its aforesaid deflection substantially only at its underside to impart thereto an upwardly directed flow component, and the upper surface ofthe casting jet is permitted to freely admix with the steel of the liquid metal pool.
- the apparatus for the practise of the method comprises a pouring tube for the throughflow of a casting jet and a distributor device cooperating with the pouring tube.
- the distributor device comprises a distributor plate secured,.preferably detachably, at the pouring tube, and the distributor plate has one or more guide surfaces for the casting jet emanating from the pouring tube, which guide surface or surfaces s ubstantially only contact the outflowing casting jet at its underside to impart'thereto an upwardly directed flow'component in the mold.
- the present invention broadly relates to the continuous casting of metals and, more specifically, pertains to a new and improved method of introducing steel into the liquid metal pool of a continuous casting mold and apparatus for the performance of the aforesaid method.
- Immersible pouring tubes with one or a number of outlet ports or openings which are located beneath the level of the metal bath in the continuous casting mold constitute a first type of expedient employed in this particular art for improving the degree of purity of the steel.
- a first type of expedient employed in this particular art for improving the degree of purity of the steel.
- US. Pat. No. 3,648,761 Canadian Pat. No. 510,528, British Pat. No. 1,249,854, German Pat. No. 160,659 and French Pat. No. 1,570,056. Since the wall thickness of conventional pouring tubes is relatively thin it is not possible to subject the cast material or casting jet to any really appreciable permanent controlled guiding action as it departs from the pouring tube, because pouring tubes tend to wear relatively rapidly and the outflow crosssection changes and thereby also the guiding action, so
- the metal is directly introduced in the form of a compact flow at the regions of the narrow sides of the mold, and at each such location is sub-divided into two streams which are directed downwardly and upwardly respectively. Due to this flow phenomena it is possible for the skin which forms at the strand to be washed away. Moreover, it is not possible to realize a really satisfactory temperature compensation at the liquid metal pool when utilizing this prior art equipment.
- a primary object of the present invention to provide a new and improved method of, and apparatus for, introducing a molten metal, typically steeL-into a continuous casting mold in a manner enabling infeed of the steel into the liquid metal pool within the mold so as to possess a controlled flow direction, and upon encountering different casting conditions, for instance upon changing the shape or format of the cast strand,
- Another object of the present invention is to provide a new and improved method of, and apparatus for, introducing steel into a continuous casting mold wherein the incoming casting jet of metal is substantially immediately deflected upwardly'after leaving the pouring tube and is not confined against partaking in such upward flow immediately after leaving the pouring tube, and wherein with the upward defllection of the incoming casting jet the same can substantially immediately admix with the metal pool at the region of the pouring tube.
- Yet a further significant object of the present invention relates to an improved apparatus for the introduction of steel into a continuous casting mold employing a pouring tube having an accessory attachment which can be preferably readily exchanged to accommodate the casting system to different casting parameters.
- Still another object of the present invention relates to a pouring tube equipped with a dish member designed to provide an accessory dish attachment for a standard pouring tube, the dish member being preferably readily exchangeable for different designed dish arrangements to readily accommodate the casting system to various mold configurations and quality requirements.
- the method aspects of this development for the introduction of steel into the liquid metal pool of a continuous casting mold for casting slabs or blooms contemplates guiding a jet or stream of molten metal enclosed at all sides about its periphery to a location beneath a metal bath and'thereafter deflecting the casting jet out of its original flow direction.
- an upwardly directed flow component there prevails at the upper surface of the deflected jet or stream of casting metal a free and unencumbered possibility of mixing with the steel in the liquid metal pool.
- This produces a flow of the melt which favorably influences the separation and distribution of non-metallic inclusions.
- the encased casting jet is advantageously divided into two jets or flow streams which are deflected in the direction of the narrow sides of the mold, so that the skin of the strand at the wide sides of the mold is not directly impinged by the steel.
- this invention is also concerned with an improved apparatus for the introduction of steel into a continuous casting mold and which is suitable for the performance of the aforesaid inventive method, and such apparatus basically comprises a pouring tube with which there is operatively associated a distributor device.
- the distributor device is designed in the form of a distributor plate and is secured, preferably detachably, at the pouring tube.
- This distributor plate provides one or more guide surfaces for the casting jet or jets departing from the pouring tube.
- the guide surface or surfaces only enclose the outflowing casting jet(s) at its underside or bottom surface and impart an upwardly directed flow component to such casting jet(s).
- the guide surface or surfaces are advantageously inclined with regard to the horizontal in an upward direction at a predetermined angle.
- the outflowing steel is upwardly guided or deflected by the guide surfaces so that the non-metallic inclusions are floated upwardly within the casting mold and taken-up by the slag. This considerably reduces the quantity of inclusions present at the cast product.
- the non-separated inclusions are distributed due to the flow prevailing at the liquid metal pool in such a manner that there does not occur any high concentration of contaminants at given locations.
- the inclination angle with respect to the horizontal which the guide surfaces may partake, and which impart to the steel a flow having a flow direction or component which is directed opposite to the direction of travel of the cast strand, can be accommodated to the momentary casting conditions which are encountered by appropriate selection of the distributor plate; as a general rule when casting larger size strands the inclination angle is chosen to be relatively small.
- inclination angle does not exceed 45 and preferably is in a range between to 35 with respect to the horizontal.
- the distributor plate possesses a dish-like configuration, with each guide surface being inclined and forming at least one trough, because in this way there can be realized a more directed flow of the metal. It is beneficial if the guide surfaces and the distributor plate, considered wtih respect to the flow direction of the deflected casting jet, are initially wider then again become smaller, running together into a tip, or if the plate itself tapers into a tip.
- a very good guiding action can be realized when using distributor plates having guide surfaces possessing one or a number of grooves or furrow-like depressions.
- the distributor device normally extends towards the narrow sides of the continuous casting mold, and the distributor plate advantageously can possess grooves which extend in diverging fashion in the direction of such narrow mold sides.
- a dowel or key may be inserted between the distributor plate and the pouring tube to prevent relative rotation between these two parts during the pouring of metal.
- Attachment of the distributor plate to the pouring tube so as to conveniently provide an accessory device for standard pouring tubes can advantageously occur through the use of any suitable attachment or connection means, typically rotary-type connections, such as a bayonet-type connection or a threaded connection, for instance.
- any suitable attachment or connection means typically rotary-type connections, such as a bayonet-type connection or a threaded connection, for instance.
- each guide surface advantageously should correspond at least to the value of the largest diameter of the associated pouring tube.
- the pouring tube possesses one or more additional outlet openings for the steel at the region or height of the distributor plate, so as to direct a certain amount of metal, for instance when casting slabs, also against the wide sides of the mold and to prevent the formation of dead angles or regions within the mold proper.
