Hardness is one of the most commonly used indexes in mechanical properties of metal materials. A fast and economical test method for hardness test is introduced in wire factory. But for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad. Generally speaking, the hardness of a metal is often thought of as the resistance of a material to plastic deformation, scratches, wear, or cutting.
In the adjustment of the dipping distance of the large galvanized wire, keep the original speed unchanged, and determine the dipping time (1) according to T = KD, where: T is the constant of the dipping time, take 4-7d is the diameter of the steel wire mm, and then estimate the dipping distance. By adjusting the zinc dipping distance, the zinc dipping time of steel wire of various specifications is shortened by 5s on average than that before adjustment. In this way, the zinc consumption is reduced, and the zinc consumption per ton of steel wire is reduced from 61kg to 59.4kg.
