Development of hot rolled wide and thin gauge deep-drawing enamel steel
With the further improvement of forming efficiency and processing yield of enamel steel,the demand for wide and thin gauge deep-drawing enamel steel increases day by day.However,there are technical bottlenecks such as scale penetration,tail swing,wave shape and poor forming performance when using traditional hot rolling technology.Therefore,hot rolling pickling wide and thin gauge deep-drawing enamel steel is developed based on thin slab continuous casting and rolling line.The chemical composition design,production process,strip surface quality and mechanical property stability control process of deep-drawing enamel steel are introduced.The research and production practice show that the mechanical properties of finished products are u-niform,and they have excellent formability,fish scale resistance and adhesion properties.The yield strength of the strip directly affects its deep drawing properties.The effective Ti content in steel,finishing rolling reduction distribution and finishing rolling temperature have significant effects on the yield strength of the strip.The coiling temperature has little effect on the yield strength of the strip.The main strengthening mechanism of deep-drawing enamel steel is solid solution strengthening and fine grain strengthening,and precipitation strengthening is weak.Based on the successful development of hot rolled pickling wide and thin gauge deep-drawing enamel steel in thin slab continuous casting and rolling line,the stable batch supply of 1.65 mm× 1 500 mm extreme gauge deep-drawing enamel steel exceeds ten thousand tons,filling the market gap.
