| titleOfInvention | Manufacturing method of high carbon chromium bearing steel |
| abstract | The present invention provides a high carbon chromium bearing steel manufacturing method capable of recoating a decarburized layer formed on a material surface by high-temperature heating in a previous step (material heating before block rolling and hot rolling). A pre-process carbon activity a s of the steel surface with a high carbon chromium bearing steel produced in decarburized layer on the surface 700 ° C. below the temperature range in exceeds 0.7 high carbon chromium bearing steel to When the spheroidizing heat treatment including the step of heating to a temperature immediately above the A c1 transformation point and the step of slow cooling is performed, the steel is in the temperature range below the A r1 transformation point in the slow cooling step. Sometimes, the atmosphere control is performed so that the carbon activity a s of the steel surface and the carbon activity a g of the atmosphere satisfy the following expression (1) and further satisfy the following expression (2) in a temperature range of 680 ° C. or lower. . 0 ≦ a g −a s ≦ 0.3 (1) a g = 1 (2) However, the maximum value of a g and a s is 1.0. It is desirable that the cooling rate in the temperature range below the A 1 transformation point is 10 to 80 ° C./hr or less. [Selection figure] None |
