摘要： PURPOSE:To obtain plural ingots with single driving rolls by providing sliding nozzle type charging flow controllers and making it possible to charge molten metal at the same timing and in the same volume into plural molds from a tundish. CONSTITUTION:With sliding nozzles 2, 2' held open, the plural molten metal outflow ports of a tundish 1 are tightly closed with the stoppers 9, 9' and molten metal is put into the tundish 1. At the point of the time when the molten metal is accumulated to a certain extent therein, the stoppers 9, 9' are opened to charge the molten metal simultaneously in the same volume into molten metal casting molds 4, 4'. Thereafter, the nozzles 2, 2' are adjusted to maintain the volume of the molten metals 5, 5' in the molds 4, 4' constant. Single driving rollers 7 are driven, whereby ingots 6, 6' are obtained.

摘要： PURPOSE:To improve the operating efficiency of continuous casting machines in a duplex continuous casting method by agitating plural drawn ingots on the same pinch rolls electromagnetically in such a way as to stride over these. CONSTITUTION:In duplex continuous casting machines which draw plural ingots 1 in parallel, a linear motor type electromagnetic agitator 3 is installed between supporting rolls 2 in such a way as to stride on the two ingots 1 supported on the rolls 2. The need for installing electromagnetic agitators for specific use to each ingot by widening the distance between the ingots is eliminated and the exchanging of the electromagnetic agitators in the stage of changing ingot shapes is obviated, whereby the operating efficiency of the continuous casting machine is improved.

摘要： PURPOSE:To prevent the lateral sliding, curving, etc. of a billet in the stage of cutting the top crop of the final billet by conveying the final billet up to a cutting position while holding the same clamped with a clamping device mounted to a gas cutting machine. CONSTITUTION:The final billet 14 that remains after ordinary cutting is pressed and clamped by a clamping device 5 and while the billet 14 is held fixed by a cutting machine body 1, the body 1 and the billet 14 are moved up to the place above a crop carriage 12. When the body 1 comes to the position above the crop carriage, a limit switch for detecting position operates to stop the body 1; at the same time, the clamping by the device 5 is released to move only the billet 14 by a prescribed distance. When the top crop 15 at the succeeding end part of the billet 14 comes to the position above the crop carriage 12, the movement of the billet 14 is stopped and the crop cutting with a cutting torch 7 mounted to the body 1 is started, whereby the top crop is cut and dropped onto the carriage 12.
摘要翻译：目的：为了防止钢坯横向滑动，弯曲等现象，通过将最终坯料输送到切割位置，同时将夹紧装置夹持在气体夹紧装置上切割机。构成：普通切割后保留的最终坯料14被夹紧装置5压紧并夹紧，并且当坯料14被切割机主体1固定时，主体1和坯料14移动到上方的位置当主体1到达作物托架上方的位置时，用于检测位置的限位开关用于停止主体1; 同时，通过装置5的夹紧被释放，仅将坯料14移动规定距离。当坯料14的后端部的顶部裁料15到达作物托架12上方的位置时，坯料14的移动停止，并且开始安装在主体1上的切割炬7的作物切割，由此顶部作物被切割并落到托架12上。

摘要： PURPOSE:To prevent the insufficient close in the time of wholly closing a stopper at the time of completing casting by automatically repeating the control of continuous pouring rate with the stopper and the wholly closing operation of the stopper controlled so that the molten metal surface in a mold becomes a prescribed level before completing the casting. CONSTITUTION:A control device 11 in a cylinder 10 for operating the opening/ closing of the stopper 8 and a casting speed control device 13 for driving pinch rolls 6 are provided. The continuous opening/closing operation of the stopper 8 is executed before completing the casting to automatically adjust the continuous opening/closing period in accordance with the metal stuck quantity and molten metal lowering rate at the time of wholly closing or the molten metal lowering speed. By keeping the metal quantity stuck on a nozzle 3 surface to the suitable quantity, the metal is worked as sealing material, and the close, contact between the stopper and the nozzle is secured. By this method, the shut-off of pouring of the molten steel with the stopper at the time of completing the casting is surely executed without insufficient close.

摘要： PURPOSE:To constitute a titled device inexpensively and easily, in a dummy bar flapper device for continous casting installation, by providing a link mechanism for spacing the side guides for supporting a dummy bar from a flapper. CONSTITUTION:In the stage of casting a slab by a continuous casting device, a dummy bar 7 is inserted into a mold 1, and a continuously cast slab 5 is drawn out in an arrow A direction along an ingot conveyance route 2. The tail part of the bar 7 enters the inside of a guide frame where it is positioned, and is cut off from the slab by a disconnecting device 12, after which it is lifted by the rollers of a flapper 4 and is hooked to a standing-by hook 9. Here, side guides for supporting a broad dummy bar are provided on both sides of the flapper 4 and side guides for supporting a narrow dummy bar which can be moved closer or further to or from the flapper 4 are provided. A link mechanism for spacing these from the flapper 4 is installed, whereby the dummy bar is separated easily from the slab and is lifted.

摘要： PURPOSE:To prevent the clogging of a nozzle by once quickly opening a stopper to the opening degree larger than the opening degree limit within which the clogging of the nozzle part is generated simultaneously with the start of the drive of pinch rolls after starting the casting and successively, once quickly and wholly closing the stopper. CONSTITUTION:Molten steel 2 retained in a tundish 1 is poured into a mold 4 through the nozzle 3. After the start of the casting, by once quickly opening the stopper 8 to the opening degree at larger than the opening degree limit within which the clogging of the nozzle 3 part is generated simultaneously with the start of the drive of the pinch rolls 6 and successively, once quickly and wholly closing the stopper, the outer force is imparted to the stuck material to the nozzle 3. When the molten steel level is lowered during the continuous molten steel level control in the mold 4 and reaches the prescribed value or lower, the stopper 8 is mutually or intermittently moved to the opening degree larger than the opening degree limit within which the clogging of the nozzle 3 part is generated and the whole closing. Thus, the clogging of the nozzle 3 is prevented.
