| Abstract: | The hot-continuous rolling process has been simulated with THERMECMASTORZ type hot simulation experiment machine and the influence of finish rolling temperature and cooling technology after rolling on yield strength of steel with 0.079% C,0. 095% Si,0. 57% Mn,0. 012% P, 0. 020% S,0. 064% Ti and 0. 060% Cu has been researched. It has found that with the technology of immediate water cooling after rolling, the finish temperature of water cooling and coiling temperature have only the influence on the pecipitating strengthening component of steel. However the change of finish rolling temperature and the beginning temperature of late water cooling after rolling have the influence both on the pecipitating strengthening component and on the grain boundary strengthening component. The corresponding quantitative estimating formula has been put forward. |
