Abstract: A horizontal continuous casting method and apparatus is disclosed. Liquid metal, held in a storage container, is continuously maintained at a height not less than the height of the continuous casting mold. Additionally, adjustment of the relative positions with respect to one another of a magnetic coil surrounding a portion of the continuous casting mold, the storage container, in both the horizontal and vertical directions and the drain pipe extending from the storage container into the continuous casting mold is disclosed.

Abstract: A continuous casting method in which molten metal is continuously poured into a moving mould cavity formed between a rotary casting wheel having a peripheral casting groove and a moving belt partially covering the peripheral casting groove. The cast billet which has been solidified at least outer surfaces thereof is continuously pulled out from the moving mould cavity by means of pinch rollers which are rotated at a peripheral speed greater than that of the rotary casting wheel.

Abstract: A process for controllng the withdrawal of a casting from a cooled, horizontal, continuous casting mold involves withdrawing the casting from the mold in a series of steps, between which steps the casting is pushed back by a partial step to insure the welding together of casting sections. A melt breakthrough of the casting skin is prevented by measuring the expansion or contraction of a wall of the mold in contact with the casting and controlling the withdrawal of the casting in response thereto.

Abstract: The present invention relates to a bow type continuous casting process using a curved mold, wherein molten steel is continuously cast into the curved mold to obtain a curved strand, e.g. a slab, having a thickness of not less than 200 mm.The improvement of this invention resides in that the curved strand is straightened at a plurality of points at regions of the strand where the thickness of the solidified shell is not more than 60 mm. The obtained strand can be directly supplied to rolling without the necessity of removing the defects from the strand or without reheating the strand.

Abstract: A method of controlling relative movement between an ingot and a mold consists of monitoring the level of the metal pool in the mold by measuring the voltage between the ingot and a mold section disposed above the metal pool, in contact with the bath of molten slag and insulated electrically from the ingot and from the ingot-forming mold section; comparing an instantaneous value of said voltage with a predetermined value and varying the relative speed of the ingot and the mold depending on a signal proportional to the difference between the instantaneous and the predetermined values of said voltage so that the predetermined level of the metal pool is restored.

Abstract: Disclosed are a method of and apparatus for radiation pyrometric temperature measurement of a continuous cast metal bar. Cast bar advancing from a continuous casting machine is continuously monitored for temperature without contacting the cast bar with any apparatus by applying a layer of soot onto the surface of the bar, detecting infrared radiation emitted from the sooted area, converting the detected radiation into a temperature signal, displaying the temperature, and completely removing the soot from the cast bar before it enters a rolling mill.

Abstract: During the continuous casting of at least two strands, withdrawn with the same speed from the continuous casting molds, the withdrawal speed for both strands should be adjusted in accordance with the quantity of cast metal, typically steel, infed to the first continuous casting mold i.e. also the level of molten metal therein. The infed quantity of steel is regulated in at least one further continuous casting mold as a function of such withdrawal speed or velocity.

Abstract: A method for controlling a casting and rolling mill by measuring the speed of a cast strip between the casting machine and the first following rolling mill and regulating the speed of the casting machine directly proportional to the measured speed of the cast strip. It is thus possible to avoid auxiliary equipment required in prior art systems such as pinch rolls and a continuous furnace between the casting machine and the first following rolling mill. Furthermore no loop on the cast strip is required. As a result, great reductions in capital expenditures, the energy required to operate the line and the necessary space can be obtained.

Abstract: A method for preventing damage to the strand guide elements of strand guide arrangements or roller aprons of a continuous casting installation for metals, especially steel, wherein it is possible to withdraw a strand which is immobile in the strand guide arrangement or roller apron, by means of a powerful withdrawal unit, without the risk of damaging elements of the strand guide arrangement. At pre-selected locations of the strand guide arrangement there are determined the withdrawal forces effective at such locations and acting upon the elements of the strand guide arrangement. Upon exceeding maximum permissible values the strand withdrawal operation is interrupted.
