使用不同基板制作成的彩钢板,其性能、用处也有所不同。更具使用基板来分,彩钢板可以分为冷轧基板、热镀锌基板、电镀锌基板等几类。对压
型钢板板型来说,浅波板的板型优于高波板。对钢板强度来说,强度加工后的板型变差的趋势越明显。高强钢的板型相对较差还有另外一个原因就
是很多彩涂生产厂仅靠降低热镀锌的退火温度来提高材料的屈服强度,这样就会导致钢板宽度方向上力学性能的不均衡。这种不均衡是由整个宽度
方向带钢温度的不均匀引起的,温度下降可能导致部分部位温度低于钢板再结晶的退火温度。
The color steel plate made of different substrate, its performance, use are also different. More use substrate to divide, color steel plate can be divided into
cold rolled substrate, hot galvanized substrate, galvanized substrate and other categories. For the pressed steel plate type, the shallow wave plate type is
better than the high wave plate. For the strength of steel plate, the trend of plate shape variation after strength processing is more obvious. Another reason
for the relatively poor plate shape of high strength steel is that many color coating manufacturers only reduce the annealing temperature of hot-dip
galvanizing to improve the yield strength of the material, which will lead to the imbalance of mechanical properties in the width direction of the steel plate.
This imbalance is caused by the inequality of the strip temperature in the whole width direction, and the temperature drop may lead to the temperature
below the annealing temperature of the plate recrystallization.
