摘要： PROBLEM TO BE SOLVED: To enable continuous casting of a cast slab having high quality even in the case of being the cast slab having thick thickness. SOLUTION: A short side block 10 is divided into three blocks 1 of side blocks 1 and a wedge block 2 in the thickness (t) direction, and on both surfaces of the wedge block 2 and on the surfaces in contact with these surfaces, inclining parts are arranged and the block width W of the short side block 10 is made changable, and the block width W can be reduced together with the shrinkage accompanying the growth of solidified shell 50b during the casting of the cast slab. A gap (g) between the short side block 10 and the solidified shell 50b, is held to =150 mm, the cast slab having high quality can continuously be cast.

摘要： PROBLEM TO BE SOLVED: To prevent the development of fine crack on the surface of a cast slab and to improve the quality of a cast slab and the yield of a product. SOLUTION: The film thickness of coating agent 10 coated on endless belt 1 is set large in the case of high casting speed and small in the case of low casting speed corresponding to casting speed and average heat flow flux in the range A within 4mm solidified shell thickness is restrained below the reference value (200×10 kcal/m .hr). By this method, strain concentration at the time of solidifying is prevented by uniformizing the solidified shell and the development of the fine crack on the surface of the cast slab is eliminated, and the quality of the cast slab and the yield of the product are improved.

摘要： PURPOSE: To make an end face level detectable easily in a highly responsive manner by installing an X-ray generator, a fluorescent screen and a television camera. CONSTITUTION: An X-ray tube 1 is set up nearby an upper part at one side of two molds 6 and 7 as being faced to the side of these molds 6 and 7. A fluorescent screen 2 is set up in an opposed position of the X-ray tube 1 at the other side. A TV 4 is set up as being opposed to this fluorescent screen 2, and the output is fed to a signal processor 5. In addition, X-rays out of the X-ray tube 1 hits on the fluorescent screen 2 after passing through X-ray transmissive windows 12, 15 and slitlike windows 23 and 14, making the fluorescent screen 2 fluoresce. A fluorescent section is a more upper part than molten metal surface (b), and a section of less than the molten surface is smelting, therefore the X-rays are attenuated and almost not reached to the fluorescent screen 2. In this consequence, the fluorescent screen 2 corresponding to the top of the molten surface is bright but the underside of the surface becomes darkened. This screen image is photographed by the camera 4 and processed by the signal processor 5, and thus the molten surface level (b) is detected.

摘要： PURPOSE:To prevent the remaining of bulging deformation of a cast slab and to enable the casting at high velocity. CONSTITUTION:At the time of continuously casting molten steel at >=2.5m/min casting velocity, the vertical vibration of the molten metal surface in the mold is prevented by forming the IPI' distance L between the upper and the lower support rolls 2 of plural pairs just below the mold to in the relation of the casting velocity V (m/min) to guide the cast slab 3. Further, in a belt type continuous casting apparatus forming the mold part with one pair of belts 52 endlessly rotated and one pair of side dams 54 interposed at both ends in the descending part, the remaining of the bulging of the cast slab 3 is prevented to support the cast slab 3 by the support rolls 2 arranging the distance between the upper and the lower rolls to

摘要： PURPOSE:To restrain molten steel flow just below a nozzle in a mold, to uniformize flow speed of the molten steel in the width direction and to prevent the longitudinal crack in a cast strip by forming the discharging hole width in the thickness direction of the nozzle to a tapered shape gradually narrowed and the center inner part of the nozzle to the divided flow structure with a partitioned wall in the thickness direction of the nozzle. CONSTITUTION:On the upper surface of the nozzle, a sprue part 2 and a nozzle pouring hole 1 from a tundish are provided, and ordinarily, the tundish nozzle is fitted to the pouring hole 1 to pour the molten metal. A pouring part 3 in the nozzle body is divided with the partitioned wall 4 so as to inject the molten metal into the mold. Further, the lower end of the nozzle is formed as arc-state in the corner part 5, and the discharging hole 8 in the nozzle is formed as the tapered shape in the inner surface at the lower end part, and at the tip part 6 of the nozzle, the discharging hole having narrow width is formed. Such a nozzle forms the uniform molten steel flow pattern in molten steel flow speed, solidified shell thickness and solidified thickness, and the uniform shell is formed.

摘要： PURPOSE:To move a plurality of sensors by one spherical motor by providing a plurality of sensors for controlling to move a normal line of a spherical gimbal to be rotated by the motor. CONSTITUTION:When a relative distance between a target and a missile is reduced and becomes a distance for sufficiently aiming at the target even by an infrared ray sensor 4 for an optical wave seeker, the sensor 4 is switched from a radio wave antenna 3 for a radio wave seeker to an infrared ray sensor 4 for an optical wave seeker, and a guiding system is switched to an infrared ray tracing system having an excellent aiming accuracy. That is, a spherical gimbal 2 is rotated by a spherical motor, and a control shaft is switched from a gimbal control reference shaft 5 for the radio wave seeker to a gimbal control reference shaft 6 for the optical wave seeker. Thus, high accuracy tracing is again continued by controlling to rotate the gimbal 2. In this case, since the antenna 3 and the sensor 4 are mounted on a peripheral surface of a direction having a different bearing angle to an axis of the missile, sensing failure does not occur.
