NON-{111} TEXTURES IN COLD ROLLED MICRO-CARBON STEEL SHEETS AND THEIR FORMATION REASONS AND COUNTERMEASURES

Non {111}textures different from the normal ones in the trial of cold-rolled micro-carbon deep drawing steel sheets was introduced. The characteristics of the non-{111} textures and their influence on the plastic strain ratio of steel sheets were studied in the practical production and laboratory experiments. The evolution along the main processing steps and the formation features of cold-rolled textures were investigated based on above-mentioned conditions.The reasons for hot rolling of the non-{111}textures was analyzed and the effect of cold rolling ratio and heating rate during batch annealing on the non-{111} textures was investigated.Finally,the countermeasures for the control of textures in cold-rolled micro-carbon deep drawing steel sheets with respect to the formation characteristics of non-{111} textures and the conditions for {111} textures to be dominant are proposed.
