    摘要： Method for the controlled pre-rolling of thin slabs (20) leaving a continuous casting plant, whereby the pre-rolling is carried out with a plurality of pairs of rolls (14-16) grouped together in one or more pre-rolling assemblies (10), the first of the pre-rolling assemblies (10) being positioned immediately downstream of foot rolls (12) of a mold (11), at least one displaceable roll (16) being included in the pairs of rolls (14-16), the pairs of rolls (14-16) being associated with pressure transducer means (18) and hydraulic capsule means (17), position transducer means (24) being included. The pressure transducer means (18) and position transducer means (24) can be associated with a data processing unit (21), at least the first of the pairs of rolls (14-16) processing a slab (20) which has just emerged from the mold (11) with a thin solidified skin. The method achieves a pre-rolling with a reduction of the thickness of the slab (20) leaving the last pair of pre-rolling rolls (14-16) by at least 10% so as to eliminate the liquid core and to bring into contact the zones in a two-phase condition in order that the central solidification structure be refined and the central separation be minimized. Device suitable to carry out the controlled pre-rolling of thin slabs according to the above method, which comprises means (25a) to monitor the temperature of the liquid bath in a tundish, means (25b) to monitor the temperature of a slab (20), means (26) to monitor the speed of the slab (20) and means (28) to monitor the inclusion of a liquid cone.

    摘要： This invention relates to the method and apparatus for improving the cast ingot, cast in a continuous casting equipment which is commonly called a "belt-and-wheel" system wherein a casting wheel and a metallic belt are employed, by applying a light reduction to the cast ingot to give elongation under compressive stress during the process wherein the curvature of the cast ingot changes as the cast ingot travels from the exit of a casting wheel.More particularly, this invention relates to cast ingot quality improvement method and apparatus in a continuous casting which aims at preventing cracks which were liable to occur on the groove bottom side of the ingot cast by the said continuous process; similarly it also aims at crushing blow holes which tended to concentrate on the groove bottom side the cast ingot.

    摘要： A continuous casting installation with a structure for cooling the mold. The continuous casting mold is provided with a cooling means formed in part by a pair of opposed upper arms which extend from the mold. A carriage means is provided for moving the mold, and this carriage means has a pair of arms extending beneath and engaging the upper arms of the mold so that the arms of the carriage means form a pair of lower arms coacting with the upper arms to support the mold on the carriage means. The upper arms form part of a cooling means for the mold, while the lower arms of the carriage means are formed with passages through which cooling fluid is directed to and from the cooling means of the mold. In this way it becomes possible to simply separate a mold from the carriage means with an automatic separation of the cooling connections, and a new mold, of a different size, for example, can replace the old mold, with the connections for the flow of cooling fluid being automatically made simply by mounting of a new mold on the carriage means.

    摘要： Method for detecting optically active organic particles suspended in a fluid, including water, air or a vacuum, by measuring circular dichroic absorption. The method comprising the steps of alternately transmitting right circularly polarized light and left circularly polarized light through the fluid being analyzed whereby the circularly polarized light is scattered by the particulate matter in the sample. The scattered radiation is analyzed by separating the circularly polarized components in the resulting scattered light and measuring the intensity of the resulting scattered light components. The circular dichroic absorption in the scattered lights is represented by the ratio of the component intensity of when starting with right circularly polarized light to that of the intensity when starting with left circularly polarized light.
