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

摘要： PROBLEM TO BE SOLVED: To provide a method for causing a hardened texture to appear by corrosion, and detecting the hardened texture of steel even if a type of the steel, especially low-carbon steel with a carbon concentration of 0.01 mass% or less has a low solute element concentration within the steel and it is conventionally difficult to clearly detect the hardened texture.
SOLUTION: In the method for causing the hardened texture of the steel, a cross section of a sample of a steel casting piece is polished. A polished surface 2 of the sample 1 is downwardly placed. An immersion depth d of the polished surface 2 of the sample is 10 mm or less. The polished surface 2 is corroded. While one or both of the sample and a corrosion liquid are vibrated by ultrasonic waves, the polished surface is corroded. Since only a portion of the sample including the polished surface (the corroded surface) of the sample is immersed into the corrosion liquid and corroded, the hardened texture appears in a type of the steel, especially the low-carbon steel with a carbon concentration of 0.01 mass% or less whose hardened texture is conventionally difficult to appear.
