PROPERTIES OF RAILWAY RAILS PRODUCED FROM LADLE-REFINED STEEL

The most effective results are obtained with vacuum degassing and ladle purging with argon and nitrogen. Vacuum treatment reduces the content of oxide phase and oxide stronger length and lowers the hydrogen content to levels at which there is no danger of hairline cracking. Vacuum treatment also lowers the ductile-brittle transition point by 20 deg, reduces anisotropy of ductile and impact properties, and increases design strength. Argon purging reduces the length of oxide stringer inclusions and improves mechanical properties.
