Basic Information
Scope
Scope: This standard specifies the packaging operation norms for angle steel and plate parts. This standard applies to the guidance and regulation of the packaging process for angle steel and plate parts. Main technical content: 1. Sorting: First, divide the area into zones and mark the packaging areas as angle steel zones and plate zones. According to the packaging list, mark the tower type, elevation, package number, part number, and quantity in the angle steel and plate zones, and clearly write them on the ground. Based on the tower type, elevation, package number, part number, and quantity, sort the parts and place them in the corresponding part number positions on the ground. Parts with the same part number should be stacked one on top of the other, with no more than 10 pieces per stack, to facilitate counting. Requirements for sorting include ensuring that the steel stamp numbers face the same direction and are flush at both ends. During sorting, no mixed parts are allowed. After sorting, a reasonable spacing (greater than the number of layers * beam width) must be maintained between different part numbers to prevent mixed parts. For angle steel parts with a beam width of not less than 100mm, after sorting by part number, the package number should be marked on the workpiece in the form of "package serial number/total package number" to facilitate subsequent packaging work. Self-inspection and special inspection should be conducted after sorting. 2. Withdrawal: Withdraw the required quantity of each tower from the sorted part numbers, ensuring that the length of the withdrawn material is not less than 50cm and that the ends of the withdrawn material are flush. Check the completeness of the withdrawn parts and their processing procedures (angle cutting, welding, flattening, root cleaning, and backside removal) according to the packaging list. 3. Labeling: Fill in the tower type, package number, part number, and quantity on the non-adhesive labels in accordance w
