彩涂鋼板最終產品板型的保證,與鋼板的強度等級、壓型鋼板的板型以及加工機器等密切相關??偟膩碚f,加工道次越多,板型越好,加工速度越
慢、板型越好。對壓型鋼板板型來說,淺波板的板型優(yōu)于高波板。對鋼板強度來說,強度加工后的板型變差的趨勢越明顯。高強鋼的板型相對較差
還有另外一個原因就是很多彩涂生產廠僅靠降低熱鍍鋅的退火溫度來提高材料的屈服強度,這樣就會導致鋼板寬度方向上力學性能的不均衡。這種
不均衡是由整個寬度方向帶鋼溫度的不均勻引起的,溫度下降可能導致部分部位溫度低于鋼板再結晶的退火溫度。
The guarantee of the final product plate type of the color-coated steel plate is closely related to the strength grade of the steel plate, the plate type of the
pressing steel plate and the processing machine. In general, the more the processing times, the better the plate, the slower the processing speed, the better
the plate. 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.
