建筑用彩鋼板一般是以熱鍍鋅鋼板和熱鍍鋁鋅鋼板為基板，主要加工成瓦楞板，或聚氨酯復(fù)合夾芯板后，用于建造鋼結(jié)構(gòu)廠房、機(jī)場(chǎng)、庫房、冷凍

庫等工業(yè)和商業(yè)建筑的屋頂、墻面、門等。彩涂鋼板最終產(chǎn)品板型的保證，與鋼板的強(qiáng)度等級(jí)、壓型鋼板的板型以及加工機(jī)器等密切相關(guān)?？偟膩?/font>

說，加工道次越多，板型越好，加工速度越慢、板型越好。對(duì)壓型鋼板板型來說，淺波板的板型優(yōu)于高波板。對(duì)鋼板強(qiáng)度來說，強(qiáng)度加工后的板型

變差的趨勢(shì)越明顯。高強(qiáng)鋼的板型相對(duì)較差還有另外一個(gè)原因就是很多彩涂生產(chǎn)廠僅靠降低熱鍍鋅的退火溫度來提高材料的屈服強(qiáng)度，這樣就會(huì)導(dǎo)

致鋼板寬度方向上力學(xué)性能的不均衡。這種不均衡是由整個(gè)寬度方向帶鋼溫度的不均勻引起的，溫度下降可能導(dǎo)致部分部位溫度低于鋼板再結(jié)晶的

退火溫度。

The color steel plate for construction is generally hot-galvanized steel plate and hot-plated aluminum zinc steel plate as the substrate, mainly processed into

corrugated board, or polyurethane composite sandwich board, used for the construction of steel structure workshop, airport, warehouse, freezer and other

industrial and commercial buildings roof, wall, door and so on. 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 decrease may cause the temperature to be below the annealing

temperature of the plate recrystallization.
