摘要

在实验室用电阻炉模拟了包钢CSP工艺生产的以62.0%和71.4%压下率冷轧的1.9 mm和1.0 mmCD01钢(0.047%C)和SPCC钢(0.041%C)冷轧板的700℃罩式退火工艺。结果表明

冷轧板退火后主要以{111}〈110〉和{111}〈112〉织构为主;71.4%压下率冷轧板快速升温退火后{112}〈110〉取向密度最大

且大角度晶界所占比例较大

织构密度较大

织构主要集中在γ取向线附近。

Abstract

The hood type furnace annealing process at 700 °C of 1.9 mm and 1.0 mm thin sheet cold rolled with 62. 0% and 71.4% reduction of ultra-low carbon steel DC01 ( 0. 047% C ) and SPCC (0. 041 % C ) produced by CSP process at Baotou Iron and Steel Co has been simulated in laboratory by electric resistance furnace. Results show that the main textures of annealed cold rolling sheet are {111}〈110〉and {111}〈112〉； the orientation density of {112}〈110〉 in cold rolling sheet with reduction 71.4% annealed with faster heating rate is greatest

the proportion of large-angle grain boundary is larger

the density of textures is higher and the texture mainly concentrates near the -y orientation fibre.
