摘要： PROBLEM TO BE SOLVED: To provide a method for applying the spraying a coating material to a tundish which can form a coating layer hard to peel.
SOLUTION: The spraying application method comprises: a stage where, while spraying a coating material to the bottom face of a tundish through a nozzle, the region to be sprayed is scanned within a bottom face so as to form a coating layer at the bottom face thereof; and a stage where the region to be sprayed is shifted to the side face 12 of the tundish, thereafter, provided that the angle between the nozzle 2 and the side face 12 is defined as α° and the expanding angle of the coating material sprayed from the nozzle is defined as β°, the region to be sprayed is made to go around along the side face under the conditions satisfying α-β/2 ≥50, the region to be sprayed is increased every time it rounds, and the cycle is repeated so as to form a coating layer at the side face.

摘要： PROBLEM TO BE SOLVED: To provide a method for detecting solidification structure of a type of steel which has relatively low differences in concentrations of solute elements due to segregation during solidification, particularly of a low-carbon steel which has a carbon concentration of 0.01 mass% or less.SOLUTION: After a cross section of a sample of steel cast slab is polished, the cross section of the sample is corroded to cause solidification structure of the steel to appear while applying supersonic waves of 30 kHz to 3 MHz to a corrosive liquid 15 in which microbubble-containing water is used as a solvent to subject the corrosive liquid 15 to water resonance. The sample is then washed and dried, and corroded holes formed in the cross section of the sample are filled with polishing powder. After transparent adhesive tape is stuck on the cross section of the sample to adhere the polishing powder in the corroded holes to the transparent adhesive tape, the transparent adhesive tape is removed and then stuck on a white mount.

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.
