STUDY ON REDUCING DECARBURISATION DEPTH OF STEEL RAILS

Influence of elapsed-time, reheating temperature and gaseous components on decarburisation depth of rails is analyzed. On this basis, the technological measures of decreasing decarburisation depth of rails are presented. Through practically industrial production, the decarburisation depth of rails is decreased to 0.2~0.5mm, which could meet the requirement of steel rails for the decarburisation depth.
