摘要： This invention provides an apparatus for producing a molten metal plated steel strip in which a gas is blown through a gas wiping nozzle (3) against the surface of a steel strip (S) being pulled up continuously from a molten metal plating bath (8) to regulate the amount of plating deposited on the surface of the steel strip. The apparatus comprises molten metal drawing members (1, 1) having a length equal to or larger than the width of the steel strip and disposed opposite to the steel strip (S) on both sides of the steel strip (S) in its part present under the surface of a liquid in a molten metal tank (9), and a shielding material (2) provided between the molten metal drawing members (1, 1) disposed opposite to the steel strip (S) on an extension of the steel strip surface. According to this apparatus, even when the steel strip width is varied, the amount of excess molten metal, which has accompanied the steel plate being pulled up from the plating bath, is reduced over the whole width of the steel strip, whereby the occurrence of splash in the step of gas wiping can be reduced.

摘要： An object is to provide a method for manufacturing a high-hardness and high-quality rail through a simple cooling process even in the presence of temperature variations in the longitudinal direction of the rail before the start of cooling.
A rail manufacturing method includes a step of accelerated cooling a rail having a temperature equal to or higher than an austenite region temperature. In the rail manufacturing method, austenite represents a portion of a region from a cooled surface of a rail head to a depth of 5 mm at the end of accelerated cooling, and the temperature of a rail head surface at the completion of heat recuperation after the end of accelerated cooling is in a pearlite transformation temperature range.
