超大规格型钢水平辊环制造与研究

Manufacture and research of super large section steel horizontal roll ring

超大规格热轧H型钢在国民经济建设中作用越来越大,而其轧制离不开超大规格的水平辊环。在研制超大规格水平辊环时,通过多层复合技术、动态效应技术消除成分偏析;通过两次热处理消除辊环铸造及热应力。世界最大型钢水平辊环的研制成功,助力国内某型钢企业成为世界首家生产1100mm超大规格H型钢,填补了国际空白。

Super large hot-rolled H section steel play an increasingly important role in the construction of the national economy,and its rolling cannot be separated from super large horizontal roller rings.In the development of super large horizontal roll rings,the composition segregation has been eliminated through multi-layer composite technology and dynamic effect technology;the casting and thermal stress of the roll ring have been eliminated through two heat treatments.The successful development of the world's largest section steel horizontal roll ring helps some domestic section steel enterprise become the first in the world to produce 1100mm super large H-section steel,which fills the international gap.
