Control of hot-rolling temperature was researched to enhance deep drawing property of cold rolled sheet, experimental results showed that hot-rolling grain became fine, the texture turned disarranged and the cold rolled texture {111} enhanced as the finishing temperature increased, while cementite class and precipitation of AlN turned ideal as the coiling temperature decreased. Moreover, lubricating rolling can avoid mischcrystal brought by lower finishing temperature, which is caused by production facility. Prototype manufacture proved that adopting improved process can obtain excellent deep drawing sheet.
