Abstract:
A rail-manufacturing method according to the present invention performs forced cooling on at least a head of a hot rail hot-rolled at or heated to the austenite region temperature or higher. The forced cooling is performed for 10 seconds from start of the forced cooling so that the cooling rate at the head surface becomes 1° C./s or higher to 20° C./s or lower, the forced cooling is performed after a lapse of 10 seconds from the start of the forced cooling until heat generation during transformation begins in the head surface so that the cooling rate at the head surface becomes 1° C./s or higher to 5° C./s or lower, the forced cooling is performed during transformation from beginning to end of the heat generation during transformation so that the cooling rate at the head surface becomes lower than 1° C./s or the temperature-rising rate becomes 5° C./s or lower, and the forced cooling is performed after the end of the heat generation during transformation until the rail-head surface temperature becomes 450° C. or lower so that the cooling rate at the head surface becomes 1° C./s or higher to 20° C./s or lower.

Claim (Index 4):
The rail-manufacturing equipment according  claim 2 , wherein the cooling medium is air or mist in the first cooling device, and the cooling medium is mist or water in the second cooling device.
