Abstract: A continuous-casting mold for strip steel has cooled broad side walls have inner surfaces bridged by and forming an upwardly open cavity with narrow walls. Liquid metal is continuously introduced from the lower end of a pouring tube into the top of and withdrawn from the bottom of the mold such that the liquid metal has an upper surface at a predetermined normally stationary level in the mold.

Abstract: The invention provides a mold for the continuous casting of steel strip. The mold is arranged with a mold cavity having a longitudinal axis parallel to the casting direction. The width of the cavity in its upstream area is sufficient to provide at least the required minimum spacing between the pouring tube and the walls of the mold.

Abstract: Apparatus and processes for use therewith are provided for the start-up of the continuous casting of strip metal, preferably steel, in which liquid metal is poured into a flared type continuous casting strip-shaped mold equipped with detector means for monitoring the instantaneous surface level of the liquid metal bath formed in the flared zone of the mold, and sensor means for sensing the presence of liquid in the core of the cast strip downstream of the mold, and means are further provided responsive to said detectors and sensor for controlling both the rate of pouring the liquid metal, and the start-up and rate of withdrawal of the cast strip to ensure the continuous presence of a liquid metal core in said cast strip downstream of said mold, for signalling when the distribution ports of the pouring tube become submerged, and for thereafter during casting maintaining a predetermined optimum operating surface level of said metal bath.

Abstract: A mold is provided for continuously casting strip metal in which the mold cavity is formed with a flared mouth the internal surfaces of which terminate at their lower end along a transversely extending line, and the reflex angles which the mold along that line at a maximum near the center line of the mold and gradually diminishing toward the side edges of the mold.

Abstract: Continuous casting apparatus is provided having a highly conductive, cooled flow-through mold, a feeder for the mold having an upstream and a downstream section with the downstream section in abutment with the mold, a heater associated with the upstream section for maintaining metal in contact therewith above liquidus temperature, the feeder sections being made of refractory material and dimensioned such that the heat from the upstream section is not bled off so rapidly into the cooling elements of the adjacent mold as to start the strand shell development in the upstream section, but sufficiently to let it start in the downstream secton of the feeder.

Abstract: A mold has two broad side walls opposing each other at a distance and being connected to two narrow walls which oppose each other and are arranged between the side walls. The upper portion of the side walls defines a funnel-shaped casting area whereby the narrow walls are arranged beyond the casting area so that the side walls extend parallel towards the narrow walls at the distance which corresponds to the width of the cast steel.

Abstract: An arrangement of coaxial neighbouring, mutually independently mounted strand guide rolls for use in a continuous casting installation for casting steel slabs is disclosed. At the region of the path of travel of the cast slab mutually neighbouring bearing or roll journals of two cooled strand guide rolls are interconnected by a coupling means which can be mounted upon the bearing or roll journals. The coupling means is provided with entrainment surfaces for the rotational movement of the guide rolls. These entrainment surfaces coact with the bearing or roll journals.

Abstract: A roller apron or strand guide arrangement for the withdrawal and/or straightening region of a continuous casting installation for the casting of strands contains two roll tracks subdivided into sections or segments containing at least two rolls for each roll track. The rolls of each track section are mounted upon a respective traverse or yoke, with the one traverse being affixed to a frame and the other traverse is hingedly connected at piston rod heads of stationarily arranged pressurized fluid medium cylinders. The piston rod heads are associated with guides at stands, the guides extending transversely with respect to the roll tracks. The guides are arranged between the roll sections at regions of parting lines between the sections and each roll section at each side of the path of travel of the cast strand possesses two pressurized fluid medium cylinders whose piston rod heads are guided at one side along a respective one of the guides.

Abstract: A segment exchanger apparatus for a continuous casting installation and a method of operating the same is disclosed, wherein there is provided an at least partially curved strand guide or roller apron subdivided into segments. The segments are mounted in stationary, straight guides. It is possible to pull any selected segment, by means of a flexible traction element operated by a stationary crane or equivalent structure, out of its stationary guide and through an inner pivotable track section. A replacement segment can be introduced, through the inner track section, into the stationary guide.

Abstract: A support guide arrangement or roller apron framework for a continuous casting installation having guide rolls and drive rolls, the rolls associated with each strand path of travel are mounted in sections at traverses or cross members and the oppositely situated traverses are adjustable by spindles as to their mutual spacing along a guide and movable away from one another, against the action of resilient load limiting means, in the presence of overloads. At least one of the oppositely situated traverses is pivotably guided at yokes which are adjustable by the spindles along the guide about axes extending essentially parallel to the rolls. At the yokes there are mounted stops which limit the positional advancement of the traverse towards a reference strand path of travel and the resilient load limiters are effectively arranged between the yokes and the traverse.

Abstract: A roller apron framework or strand guide framework for supporting a partially solidified strand in a continuous casting installation, especially for casting slabs, comprising a number of rollers mounted within the maximum slab width. Guide rings are arranged in overhung position upon bearing journals provided for an intermediate portion of the guide rollers, the bearing journals protruding outwardly past the bearings of the rollers.

Abstract: A roller apron for a continuous casting installation and serving to support a partially solidified strand cast at a continuous casting installation, especially a steel strand. The roller apron comprises a number of pairs of rollers of different diameter arranged in succession in the direction of travel of the strand. The cast strand is preferably a slab and there are arranged in alternate sequence in the roller apron larger size rollers mounted externally of the maximum slab width and one or more smaller size rollers, wherein each such smaller size roller has at least one of its bearings or supports mounted within the maximum slab width.

Abstract: A roll segment for supporting and guiding continuously cast metal strands fed therethrough, said segment comprising opposing rolls for contacting the opposite sides of a continuously cast metal strand cast through a mold and passed from said mold between said rolls. First support means for supporting the roll in contact with one of said opposite sides of said strand, second support means for supporting the roll in contact with the other of said opposite sides of said strand. Linkage means at the opposite ends of said rolls interconnect said first and second support means and maintain said rolls in substantially parallel alignment at the opposite sides of said strand.

Abstract: A strand guide framework for supporting a partially solidified strand in a continuous casting installation consisting of at least two guide roller pairs which follow one another in the direction of travel of the strand, the guide roller pairs being provided with supporting rolls, the lengthwise axes of which are arranged with the lengthwise axes of the guide rolls approximately in a plane located transverse to the axis of travel of the strand and wherein the framework is equipped with secondary cooling means or devices. According to the invention the support or supporting rollers are each provided with two support collars for the guide rollers, and the diameter of the support rollers determined by the permissible mechanical loading and the space required for the secondary cooling device determines the minimum spacing of the successive guide rollers.
