摘要： PROBLEM TO BE SOLVED: To measure a roll gap with high accuracy for a long time by suppressing a phenomenon in which a foreign substance is stuck while ensuring the safety of a sensor head without changing the length of protrusion of the sensor head from a sensor housing. SOLUTION: A sensor head 11 is constituted of a body 11a and a head portion 11b conically continuing to the end of the body 11a and having a shape in which a top of the head portion is bent like convex for a roll 4 side, and an annular step portion 11e is provided between the lower end of the head portion 11b and the upper end of the body 11a. In the device, the sensor head 11 which has contacted the roll 4 is pressed downward, and when the lower end of the head portion 11b enters the sensor housing 12, a receiving portion A having an annular band-like bottom surface is formed, and a foreign substance x is received in the step difference 11e. When the sensor head 11 moves back to the original position, the foreign substance x is pushed out as it is by the step difference 11e, thereby preventing sticking of the foreign substance.

摘要： PROBLEM TO BE SOLVED: To predict the time when a roll is broken due to a bearing of the roll in a continuous casting apparatus. SOLUTION: A roll gap measurement device installed on a dummy bar 1 passing through a cast piece passage of the continuous casting apparatus previously measures the gap between oppositely provided rolls 4 and 5 at a plurality of times with time interval. The time-series tendency of the difference between the measured result and a reference value is checked, and the time period when the difference becomes not less than a predetermined value is estimated based on the time-series tendency of last time, and the time period is determined to be the time of breakage of the roll. Thus, the rolls can each be replaced before breakage of a bearing. COPYRIGHT: (C)2010,JPO&INPIT

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 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.
