METHOD FOR RAIL STEEL PRODUCTION |
| 摘要 |
The invention relates to ferrous metallurgy. A method for rail steel production involves charging of metal charge into the furnace, its melting, steel discharge into the ladle, deoxidation, modification and microalloying of steel with ferroniobium, providing niobium content in rail steel at the level of 0.005 - 0.020 wt. %. The invention allows to obtain high-quality rail steel with high impact hardness at the low expenditure of the alloying element.
