When the welded can body is expanded in the pail can manufacturing,it shrinks in the direction of can height.
The change of height of can is influenced by r-value.The effect of annealing temperature and coiling temperature on the r-value of niobium (Nb) and boron (B) combined added extra low-carbon steel was investigated by using commercial steels.
Ferrite grain size of annealed sheet decreased with the decrease of annealing temperature. At the same time,the orientation density of {001} <110> increased and the r90°-value decreased.
The behavior of the decrease of r90°-value was dependent on the coiling temperature of hot-rolled sheet. The r90°-value decreased rapidly for low coiling temperature as the annealing temperature decreased.
