Length mismatch

Defect Name: length nonconformity < br / > definition and appearance: < br / > if the actual length of steel plate exceeds the standard or the allowable deviation specified in the contract, it is called length nonconformity. There are two kinds of length difference: long ruler and short ruler. < br / > causes: < br / > ● the shear length of flying shear is set improperly< Br / > ● the straightener is not pressed down well and the measuring wheel slips< Br / > ● there is oil stain on the surface of the steel strip, resulting in relative movement< Br / > hazard: the subsequent process cannot be cut to the specified size< Br / > prevention and elimination methods: < br / > ● reasonably set the shear length of flying shear, and frequently recheck the length< Br / > ● strengthen the maintenance and operation of flying shear, straightener and measuring wheel< Br / > ● remove the oil stain on the steel strip surface to prevent relative movement of the steel strip< Br / > inspection and judgment: < br / > ● measure with measuring tools< Br / > ● the measured length of steel plate shall not exceed the allowable deviation specified in the standard, otherwise it shall be changed< br/>
