Study on the Soaking Condition of High Carbon Chromium Bearing Steels

Abstract:

In order to seek the proper soaking condition of a high carbon chromium bearing steel, 100Cr6, a new approach was investigated considering the diffusion of chromium atoms. Although it is true that the large carbides are bigger with the worse degree of center segregation of continuously cast blooms, the size of center segregation band in blooms has a more accurate relationship with the degree of center segregation. Therefore, on behalf of the large carbide size in the conventional method, the size of center segregation band in continuously cast blooms of the steel has been used for the new approach. As a result, the center segregation and large carbides in them were removed completely by the new soaking condition.
