| titleOfInvention | A kind of preparation method of sulfur-bearing ultralow titanium high standard bearing steel |
| abstract | The present invention relates to a kind of production method of round steel, specially a kind of preparation method of sulfur-bearing ultralow titanium high standard bearing steel.Preparation method includes converter smelting process, LF external refinings process, VD stove vacuum refinings process, bloom continuous casting process and rolling process step.Converter is smelted using double slag process, terminal [C] is controlled 0.15%~0.25%, tapping process is using skimming ball and the dual pushing off the slag operation of slide plate, using Slag treatment is taken off before into LF, white slag operation is formed as early as possible, ensures suitable thickness of slag layer before VD, VD feeds sulphur iron wire after breaking sky, ladle pouring latter stage, heating time was appropriately extended using cold charge in rolling strand using steel remaining slag operation is stayed.Sulfur-bearing ultralow titanium high standard bearing steel excellent cutting performance produced by the invention, degree of purity is high, Ti content can control within 10ppm, oxygen content can control within 6ppm, castability is good, not needing to carry out to feed the processing of silicon barium line even to pour more than 10 stoves, and production efficiency is high. |
