Dynamic phosphorization device and method for metal wires

Abstract

The invention provides a dynamic phosphorization device and method for metal wires and solves the technical problems that the existing phosphorization device occupies a large space, is low in phosphorization efficiency, is poor in phosphorization effect and cannot meet later drawing acceleration requirements. The dynamic phosphorization device is provided with a phosphorization trough, a power supply and a liquid storing tank and is further provided with a conducting device and a wire coiling device, wherein the conducting device is close to the wire inlet position of the phosphorization trough, and the liquid storing tank is arranged below the phosphorization trough and connected with the phosphorization trough through a water inlet pipe and a water return pipe; the wire coiling device comprises a winding drum and a wire coiling driving device, the winding drum is arranged in the phosphorization trough, the winding drum is connected with the wire coiling driving device through a winding drum shaft, and the winding drum shaft penetrates through the side wall of the phosphorization trough; and the inner surface of the phosphorization trough is provided with a metal electrode plate, the metal electrode plate is connected with a positive electrode of the power supply through a cable, and the conducting device is connected with a negative electrode of the power supply through a cable. The dynamic phosphorization device and method are widely applied to the non-acid-pickling drawing field of the metal wires.

Description

technical field [0001] The invention relates to a non-pickling drawing equipment for metal wires, in particular to a dynamic phosphating device and method for metal wires. Background technique [0002] In the production of metal wire drawing, phosphating is generally used as the surface treatment method before metal wire drawing. The phosphating film is used as a lubricating coating carrier and the surface quality, mechanical properties, mold consumption, finished product anti-rust and quality of the drawn wire. Productivity, etc. have a lot to do, and the thickness of the phosphating film is an important indicator of production process control. The existing on-line phosphating belongs to dynamic phosphating, and its device is usually a long straight tank type. The metal wire passes through the phosphating solution in the tank to complete the phosphating process. The weight of the phosphating film is usually 3-5g / m 2 . Since phosphating treatment takes a certain amount of ...
