Method of thermal diffusion alloy plating for steel wire on continuous basis

摘要

A method of thermal diffusion alloy plating for steel wire including the steps of continuously detecting the quantity of metal plated, plated metal composition, plating composition gradient or combination thereof, in thermal diffusion alloy plating effected continuously on steel wire. Detection of these valves is performed by an energy dispersive type X-ray fluorescent analyzer and upon detecting any variation in these values, a control signal is given to a control unit to adjust automatically the plating electric current and the diffusion heating quantity, thereby imparting the desired quantity of metal plated, the desired plated alloy composition ratio and the desired plating composition gradient uniformly in the lengthwise direction of steel wire.
