Abstract: When a molten steel (106) is supplied into a moving mold defined by concave rolls (101, 102) and side checks (103, 104), the molten steel (106) is cooled by the surfaces of the rolls (surfaces except steps) to form solidified shells (111, 112). Both solidified shells (111, 112) are pressure bonded, and pulled out as a cast piece (113). A heat insulator (ceramic coating) has been applied to the circumferential surfaces of steps (101a, 101b, 102a, 102b) which are opposite end portions of the rolls. Thus, at these portions, heat dissipation does not proceed, and no solidified shells are formed. Hence, clearances are formed between the opposite ends of the solidified shells (111, 112) and the side checks (103, 104), and the solidified shells (111, 112) do not contact the side checks (103, 104), with the result that the wear of the side checks (103, 104) is prevented.

Abstract: Provided is a shape detection device capable of detecting meandering of a strip with high accuracy and a method thereof.

Abstract: An evaporation source having a nozzle structure that makes the distribution of film thickness uniform in the width direction of a substrate and a vacuum evaporator using the same are provided. A vapor produced by evaporation or sublimation by heating to evaporation material is discharged from a long nozzle opening like a band. A deposited substrate is transferred in a direction perpendicular to the longitudinal direction of the nozzle opening while facing the nozzle opening. A discharge flow rate of vapor per unit area in the longitudinal direction of the nozzle opening is made to be maximum in a portion at a nozzle width direction position corresponding to a substrate edge position rather than a central part of the nozzle opening and a plurality of partition plates providing directivity to the flow of vapor are arranged inside the nozzle opening.

Abstract: An on-line roll grinding method for a work roll, which can decrease an overshoot, by which the pressing load of a rotating grinding wheel on a work roll exceeds a set grinding pressing load, is provided. This method is an on-line grinding method for a work roll, adapted to press a rotating grinding wheel (3a) having elasticity against a work roll (1) of a rolling mill to grind the work roll, wherein when the pressing load of the rotating grinding wheel (3a) reaches a set load F, which has been set beforehand, after the rotating grinding wheel (3a) contacts the work roll (1), the forward velocity of the rotating grinding wheel (3a) is reduced to decrease an overshoot by which the pressing load of the rotating grinding wheel (3a) on the work roll (1) exceeds a set grinding pressing load F0.

Abstract: The present invention provides a liquid wiping apparatus that can eliminate the increase in the thickness of membranous liquid and defects in the surface quality resulting from the attachment of splash onto the surface of a metallic strip and can improve the productivity in a manner of accelerating the line speed. The liquid wiping apparatus according to this invention includes blade wipers for contacting with a molten metal having been attached onto the metallic strip 1 to mechanically wipe the molten metal. In the liquid wiping apparatus, a pressure applying means 7 of the static pressure pad type using gas is installed at the outlet side of the blade wiper 6 in the strip running direction, and phase-mixed flow of gas/liquid 15 is produced in membranous liquid running between the blade wiper 6 and the strop 1.

Abstract: A steel plate splicing facility includes, a steel plate heating apparatus for retrieving and heating a preceding steel plate and a following steel plate, and a shear-joining apparatus for clamping a tail end portion of the preceding steel plate and a leading end portion of the following steel plate in an overlapping condition by a die and a clamp and shearing them with a punch, such that surfaces of the tail end portion and the leading end portion are newly formed and brought in contact with each other in order to them. The shear-joining apparatus joins the preceding and following steel plates at a temperature equal to or higher than 350° C. and at a percentage clearance c/t equal to or lower than 5%, c/t being defined by c/t=D/(t1+t2)×100 where D represents a distance between the punch and the die, and t1 and t2 represent a thickness of respective steel plates.
