摘要： The method for manufacturing galvanized steel sheet has a step of adjusting the surface texture thereof by blasting solid particles against the surface thereof. The surface texture is defined by at least one parameter selected from the group of parameters consisting of mean roughness Ra on the surface of steel sheet, peak count PPI on the surface of steel sheet, and filtered centerline waviness Wca on the surface of steel sheet. The galvanized steel sheet has a surface in dimple-pattern texture.

摘要： A method for supplying rolling oil for cold rolling comprises the steps of: supplying emulsion rolling oil using a first rolling oil supply system supplying the emulsion rolling oil to a roll and a steel sheet in a recirculation mode and a second rolling oil supply system supplying the emulsion rolling oil to only the front and back surface of the steel sheet, wherein the emulsion rolling oil, which is added with an emulsifier of the same type and concentration with respect to the amount of oil as those of the emulsifier of the first supply system and controlled so that the average particle diameter of emulsion is larger than that of emulsion of the first supply system, is supplied from the second supply system; and joining the emulsion of the second supply system to the emulsion of the first supply system.

摘要： A surface treatment facility of metal plate comprising at least one centrifugal projector for projecting solid state particles having a mean particle diameter of 30-300mum toward a metal plate being carried continuously. The projector comprises a centrifugal rotor having a rotary shaft disposed such that the line of intersection between a plane perpendicular to the rotary shaft and the plane of the metal plate is parallel TO the advancing direction of the metal plate or inclined at an angle of 45˚ or less.
