钢格板制作全过程它是如何制作出来的呢请看最新信息,河北振驰钢格板厂会随时发布关于钢格板知识,我厂随时欢迎新老客户前来我厂参观指导,我厂全天热线:132-7333-6899  下面小编介绍原材料为40mm宽、3mm厚Q235B扁钢,间距为30mm,横杆的间距为50mm 的产品进行制作过程:

1.准备原材料
本次生产的钢格板采用40mm宽、3mm厚Q235B扁钢,间距为30mm。横杆的间距为50mm。
2.钢格板的焊接
钢格板的焊接为机械压焊,机器压焊使用高压电阻压焊机,机械手自动将横杆横放在均匀排列的扁钢上,通过强大的电焊功率和液压力将横杆压焊入扁钢内,从而得到焊点牢固,稳定性和强度极高的钢格板。 手工焊接需要先在扁钢上冲孔,然后将横杆放入孔内电焊,横杆会与扁钢之间存在缝隙,并且不能每个点都焊接到,因此焊接不牢固,强度会不如机械焊接。
3.切割
 根据钢格板图纸中的尺寸,焊接完成后的整块钢格板还必须进行机械切割。(高效节能钢格板剪床介绍)切割的时候严格控制尺寸误差,切割完成后由专业的质检人员对已经切割好的钢格板进行抽样检查,不合格的钢格板重新切割。
4.端板(包边板)焊接
端板与钢格板中的扁钢材质型号相同,采用人工焊接的方法进行焊接。焊接的时候清除钢格板表面的油污以及污渍之后才能进行焊接,焊缝为单面角焊缝。钢格板的每条扁钢都需要与端板进行焊接。焊接完成后对表面除渣并打磨光滑。
5.热镀锌
热镀锌是钢格板必不可少的工序,在镀锌之前应该选择喷砂或者抛丸出去表面的锈迹,做到表面没有油迹、锈迹以及其他的污物。
镀锌后的平均锌层重量不小于460克/平米,镀锌后的质量应该符合GB/T13912规定。
6.包装以及运输
