摘要： A moving inspection device capable of realizing significant size reduction/weight reduction without affecting the inspection performance for an inspection target, a moving inspection method, and a method for manufacturing a steel material. A moving inspection device includes: a moving inspection device body configured to inspect an inspection target for defects while moving over a surface of the inspection target; and water supply devices separate from the body and configured to supply water required for the inspection onto the surface of the inspection target. The body is installed with a flow adjustment plate configured to push out the water supplied onto the surface of the inspection target from the water supply devices in the advancing direction and form streamlines for supplying the water between inspection sensors configured to inspect the inspection target for defects and the surface of the inspection target simultaneously with the movement of the body.

摘要： An exhaust gas treatment method by which mercury contained in exhaust gas can be separated and removed efficiently and inexpensively. The method includes cooling an exhaust gas containing mercury in metal vapor phase by spraying water or other methods to condense mercury in the exhaust gas from metal vapor phase into metal liquid and thus to separate and remove mercury from the exhaust gas. When the exhaust gas is cooled by spraying water, the sprayed water is collected and separated into separated water and a solid containing mercury that has condensed to metal liquid, and mercury is recovered from the solid. The metal mercury particles that have condensed to metal liquid are dispersed in cooling water. The metal mercury particles can thus be easily separated and recovered by using a suitable separation device.

摘要： A steel sheet temperature control device including: a sheet temperature measurement unit; a furnace temperature measurement unit; an influence coefficient calculation unit; a control model setting unit that sets a control model; a state variable/disturbance estimation unit that estimates values of a state variable and a temperature disturbance variable of the control model at the same time; a furnace temperature change amount calculation unit that calculates a furnace temperature change amount of each of heating zones of a heating furnace under a constraint condition such that square sum of a deviation between a target value and the actual value of the temperature of the steel sheet at the outlet side of the heating furnace becomes minimum; and a furnace temperature control unit that controls a fuel flow rate used in each of the heating zones to achieve the calculated furnace temperature change amount.

摘要： A resin coated metal sheet includes: a metal sheet; and a resin layer formed on at least one face of the metal sheet. A movable amorphous amount of the resin layer measured by a temperature modulated differential scanning calorimeter being 30% to 46%. An intensity ratio I1,096/I1,119 between intensity (I1,096) of a peak attributable to a trans structure of methylene groups in polyethylene terephthalate (PET) around 1,096 cm−1 determined from laser Raman spectroscopic analysis measured by making a plane of polarization of linearly polarized laser light incident on a thickness direction section of the resin coating layer perpendicularly to a thickness direction and intensity (I1,119) of a peak attributable to a gauche structure of methylene groups in PET around 1,119 cm−1 determined from the laser Raman spectroscopic analysis being 1.1 or more and less than 1.5 at a position with a distance of 1 μm from the metal sheet.

摘要： Provided is a method for producing a galvannealed steel sheet. When the steel sheet passing through the soaking zone is a type of steel containing 0.2 mass % or more of Si, both dry gas and humidified gas are supplied to the soaking zone, where the humidified gas is supplied only from the humidified gas supply port positioned in a latter part of the soaking zone among a plurality of humidified gas supply ports, where the latter part of the soaking zone is determined considering a sheet passing speed V and a target temperature T on the exit side of the soaking zone.

摘要： Provided is a grain-oriented electrical steel sheet that combines low iron loss and low magnetostriction, together with an advantageous production method therefor. A grain-oriented electrical steel sheet comprises a linear strain portion extending in a direction intersecting a rolling direction of the grain-oriented electrical steel sheet, wherein the linear strain portion has a stress distribution in which a compressive stress region and a tensile stress region alternate in a longitudinal direction of the linear strain portion. The linear strain portion is formed by vibrating the grain-oriented electrical steel sheet in a sheet thickness direction, while irradiating a surface of the grain-oriented electrical steel sheet with an electron beam by repeatedly moving and detaining the electron beam in the direction intersecting the rolling direction of the grain-oriented electrical steel sheet.

摘要： A method for evaluating a delayed fracture characteristic of a metal material that performs a step including a step (A) and a step (B) below once or a plurality of times to evaluate the delayed fracture characteristic of the metal material having been processed. Step (A): a step that brings an aqueous solution which includes a chloride ion into contact with a surface of the metal material to cause chloride of 1000 to 100000 mg/m2 in chloride amount to deposit to the surface. Step (B): a step in which the metal material to which the chloride has deposited in the step (A) is left stationary in an air atmosphere at a temperature from −50 to 10° C. and at a relative humidity higher than or equal to a deliquescence humidity of the chloride.
