Process Control For The Structure Of Martensite/Austenite Islands of 15.3mm X100 Pipeline Steel In BX STEEL

摘要：

This paper mainly studies the influence of deformation amount and cooling rate, which existed in X100 pipeline steel rolled at 2300mm rolling mill in BX STEEL, on morphology, size relations and distribution of M/ A islands of steel plate structure. Experimental results show that structures of M/ A islands are homogenized and refined under the conditions of appropriately increasing the deformation amount in non-recrystallization region on basis of rational deformation amount in recrystallization region and cooling rate after deformation, respectively. Finally,according to the actual situation of 2300mm hot rolling mill, this paper gives rational deformation amount and cooling rate used to obtain ideal structure of M/ A islands.
