Baotou steel with knowledge

1 dozen steel belt, packing tape, packing sheet, bluing packing belt, paint packaging with the appearance of the color and appearance quality, play the steel belt, packing tape, packing sheet, bluing packing belt, paint packaging tapes monitored part of the platform, with a meter long ruler on the concave side of the strip, maximum distance measuring meter scale to the concave side. 2. Baotou steel belt, packing tape, packing sheet, bluing packing belt, paint coating thickness of packing tape and galvanized thickness measuring instrument with accuracy of response measurement. The site measurement should be from the edge of steel strip is not less than 3 mm, roughly equal intervals, and the length of not less than 100 mm. Three measuring points on each side, the arithmetic average of the six test values, or the thickness of the zinc coating is the coating thickness. 3. Every batch of steel belt, packing tape, packing sheet, bluing packing belt, paint packaging tapes on the number of test items, sampling, sampling methods and test methods should be consistent with the provisions of the state. 4. The tensile test sample should be consistent with YB/T025 - The provisions of the 1992 samples using without machining of rectangular cross section shape. The original cross-sectional area calculation according to the measured size.
