摘要： PROBLEM TO BE SOLVED: To provide a jetting nozzle capable of achieving a higher level of uniformity in atomizing distribution in the width direction of a slitlike discharge opening in a simple structure, and to provide an atomizing method using the same. SOLUTION: The jetting nozzle is provided with the two slitlike discharge openings 2a, 2b parallely formed at the top end of a nozzle main body 1, a first flow passage 3 formed on the upstream side of the discharge opening, a second flow passage 4 reduced in a flow passage width, and a third flow passage 5 with a flow passage width larger than that of the second flow passage. A notched recessed groove 6 forming a communicating flow passage 7 extends in an axial direction from the downstream end of the third flow passage 5 to the middle part of the second flow passage 2, and the downstream end of the notched recessed groove 6 forms a collision wall 8 to which a fluid from the upstream side may collide. The notched recessed groove 6 is formed by facing the opposing wall of the second flow passage. Further, the two discharge openings 2a, 2b are formed in parallel in a direction opposing to the notched recessed groove 6. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for detecting a solidified end in a continuous casting machine, by which method and apparatus, the position of the solidified end can be exactly, quickly, and stably recognized.
SOLUTION: The method and the apparatus for detecting the solidified end detects the solidified end 4 of a continuously cast slab as follows. In a roll segment 6 of the continuous casting machine, the loads applied to at least two supporting columns 9 arranged on upstream side and downstream side of a casting position respectively among supporting columns 9 connecting upper and lower frames (7, 8) are measured by a load measuring instrument 10 provided on the upper portion of the segment. A load R for the segment is represented by the sum of the respective loads applied on the respective supporting columns arranged on upstream and downstream sides. The solidified end 4 of the continuously cast slab is detected based on the value of the load R for the segment during the continuous casting. The loads R for the segment are measured in a plurality of the roll segments 6 in the neighborhood of the outlet 22 of the cast slab in the continuous casting machine. The solidified end 4 of the continuously cast slab is detected based on the variation of the load R for the segment with time during the continuous casting.

摘要： PROBLEM TO BE SOLVED: To suppress outflow of inclusions in a molten steel from a ladle when supplying the molten steel from the ladle to a tundish.
SOLUTION: A carbon heater 35 is arranged in a lid 31 installed on the ladle 1 when charging the molten steel in the ladle into the tundish 22 of continuous casting equipment from the ladle 1 where the molten steel after secondary refining is stored. The lid 31 is heated by the carbon heater 35 till the charging of the molten steel in the ladle to the tundish 22 is completed after the lid 31 is installed on the ladle 1 set on a turning table 42 of a turret 41. Power is supplied to the carbon heater 35 from a power supply unit 43. Heat released from the lid 31 is reduced, descending flow in the molten steel in the ladle 1 is suppressed, and the floating-up of the inclusions is promoted.

摘要： PROBLEM TO BE SOLVED: To provide a spray cooling method where the controllable range of heat reduction amount in a slab by spray cooling in continuous casting can be increased without performing equipment investment on a large scale.
SOLUTION: A spray nozzle 3 (collision type nozzle 3a) of spraying a cooling medium from at least two injection ports 4a, 4b and spraying the same so as to be collided at a collision angle θ till the respective spray flows 5a, 5b reach the surface 1 of a slab is adopted, and also, the distance (nozzle height H) from the spray nozzle 3 to the surface 1 of the slab is made the short one of ≤220 mm, thus, even when cooling water content W is increased, the thickness L of the sprayed water in the casting direction can be fixedly held. Since the surface area A of the sprayed water is fixedly held, heat reduction amount Q larger than that in the conventional case can be realized when the cooling water content W is increased, thus the controllable range of the heat reduction amount Q in the spray cooling can be expanded.

摘要翻译：要解决的问题：提供一种喷雾冷却方法，其中通过连续铸造中的喷雾冷却可以增加板坯中的减少热量的可控范围，而不需要大量进行设备投资。解决方案：喷射喷嘴3（碰撞型喷嘴3a），其从至少两个喷射口4a，4b喷射冷却介质并将其喷射以便以碰撞角θ相撞直到各喷射流5a， 5b到达板坯的表面1，并且从喷嘴3到板坯的表面1的距离（喷嘴高度H）也是≤220mm的短的一个，因此即使当冷却水含量 W增加时，可以固定地保持喷射水在铸造方向上的厚度L。由于喷射水的表面积A被固定地保持，当冷却水含量W增加时，可以实现比常规情况下更大的减热量Q，因此喷雾冷却中的减少量Q的可控范围可以扩大。版权所有（C）2007，JPO＆INPIT
