介绍几种利用连铸板坯轧制工字钢的新方法

DESCRIBE THE NEW METHODS OF C.C. SLAB INTO BEAM BLANKS FOR LARG I—SHAPES

扩大连铸的用途,改善其轧制方法是当前冶金工业提高成材率和节能的重要课题之一。近年来,国外在这方面取得了较大的进展,本文着重介绍了国外几种利用连铸板坯直接轧制工字钢异型坯的新方法,分析了造成工字钢端部舌形切损的原因,提出了目前存在的问题和今后的研究方向。

In order to increase the yield of products rolled steel and save energy, it is one of important problems for metallurgy industry to extend the uses of slab and improve its rolling method, in recent years,a great progress has achieved abroad. This article describes the new methods of C. C slab into beam blanks for larg Ⅰ—shapes. The cause which ereats the end crop loss of Ⅰ—beams has been analysed.The problems and research direction have been put forward.
