The Production Technology in High-Performance and Economical Hot-Rolled Ribbed Wire Rod

Abstract:

According to the production actual situation of the hot-rolled ribbed wire rod in Fangda special steel technology Co., Ltd, Through optimizing the rolling process to improve rolling organization , and with low alloy composition, which can greatly save resources and production cost. The results show that the yield strength of hot-rolled ribbed wire rod is 510MPa, the tensile strength is 622MPa, and the elongation is 23.35%, but the content of Mn can be decreased 58.13%, the content of Si can be decreased 67.50% compared with the national standard upper limit value in HRB400; The grain size scale of edge microstructure is 9.0 at the 1# flying shear in the rolling process, the grain size scale of core microstructure is 8.5, and the edge microstructure of hot-rolled ribbed wire rod after rolling is the tempered sorbite, the grain size scale is 13.5, the core microstructure is the ferrite-pearlite, the grain size scale is 12.0, and the depth of hardening is 0.50mm.
