Pa.为了提高在超低氧范围内碳脱氧速度,应选择浅平的熔池,并加强熔池搅拌,提高钢液中氧的表观传质系数.","authors":[{"authorName":"薛正良","id":"21080cbe-4a9b-46af-82cd-ed96671f1555","originalAuthorName":"薛正良"},{"authorName":"李正邦","id":"b8f8fff6-1d74-4dad-af98-8e62956ec22b","originalAuthorName":"李正邦"},{"authorName":"张家雯","id":"94d55e7c-e480-4752-9cfe-d0d502b0da9e","originalAuthorName":"张家雯"},{"authorName":"高银露","id":"f7976d76-4abd-4130-a410-390c07253b66","originalAuthorName":"高银露"}],"doi":"","fpage":"5","id":"e65ee2d2-4c61-41a1-9569-9d1483de12c1","issue":"5","journal":{"abbrevTitle":"GTYJXB","coverImgSrc":"journal/img/cover/GTYJXB.jpg","id":"30","issnPpub":"1001-0963","publisherId":"GTYJXB","title":"钢铁研究学报"},"keywords":[{"id":"ceac0700-5dca-4bd7-a7ce-9a6721223f97","keyword":"超低氧钢","originalKeyword":"超低氧钢"},{"id":"301d3548-69ec-4a52-9351-f79d0d775ead","keyword":"<span
