通过实验室4辊轧机和保护气氛管式退火炉,对0.04C钢CSP工艺生产的3 mm热轧板进行冷轧(至0.8mm)和退火试验,并用蚀坑法对退火试样进行织构分析;同时对包钢薄板厂CSP3 mm热轧板冷轧的1.2 mm板 卷退火试样进行了X-射线检测。结果表明,1.2 mm SPCC冷轧板退火织构表层有较弱的{111}织构组分,中心层没有发现有利于提高钢的深冲性能的{111}织构。1.2mm板卷退火试样{111}/{100}取向密度比为2.0~3.0
与 实验室蚀坑法的试验结果一致。
Abstract
The annealing test of 0.8 mm sheet cold rolled from 0.04C steel 3 mm bot rolled strip produced by CSP process has been carried out by 4- high rolling mill and tube funace with protective atmosphere in laboratory
and the tex- ture of annealed samples was analyzed by using etching pit method
while the annealed samples of 1.2 mm strip cold rolled from 3 mm bot rolled strip produced by CSP process at sheet plant
Baotou Steel were examined by X- ray method. The re- sults showed that there was weak {111}texture component in annealing texture of surface layer of 1.2 mm SPCC cold roll- ing sheet and{111} texture which is available to increase deep-drawing property of steel was not found at center layer. The {111}/{100|orientation density ratio of1.2 mm sheet annealed samples was2.0~3.0 which was equal to that by etching pit method in laboratory.
