Abstract

The invention relates to a preheating-type upwardly-heating steel wire zinc-plating furnace. The preheating-type upwardly-heating steel wire zinc-plating furnace comprises a zinc furnace, a zinc pot and a water-cooled wire guiding mechanism, wherein a wire shouldering roller is arranged above the zinc pot and at the position close to the front end of the zinc furnace; a press roll is arranged above the zinc pot and at the position close to the back end of the zinc furnace; the preheating-type upwardly-heating steel wire zinc-plating furnace is characterized in that a zinc pot upwardly-heating device is arranged above the zinc furnace; a steel wire preheating system is arranged in front of the zinc furnace; the steel wire preheating system comprises steel wire preheating box furnaces, an air preheater device and the zinc pot upwardly-heating device; two steel wire preheating box furnaces are symmetrically arranged left and right; the air preheater device is arranged between the two steel wire preheating box furnaces; a flue gas inlet of the air preheater device is communicated with the front end of a flame path of the zinc pot upwardly-heating device through a first flue gas heat-preserving connection pipeline; a flue gas outlet of the air preheater device is communicated with flue gas inlets of preheating flame paths of the steel wire preheating box furnaces through a second flue gas heat-preserving connection pipeline. The preheating-type upwardly-heating steel wire zinc-plating furnace can prolong the service life of the zinc pot, save energy and effectively improve the zinc-plating quality and the zinc-plating speed.

Description

technical field

[0001] The invention relates to a device for galvanizing metal wires, in particular to a preheating type upper heating steel wire galvanizing furnace. Background technique

[0002] In order to improve the corrosion resistance of the steel wire, it is usually necessary to galvanize the surface of the steel wire and cover a layer of metal zinc on the surface of the steel wire.

[0003] The general process of galvanizing operation is as follows: (1), first use alkaline liquid to carry out alkaline cleaning on the steel wire, and then use clean water to wash off the alkaline cleaning liquid on the surface of the steel wire; (2), then use acidic liquid to pickle the steel wire, Then wash off the acidic liquid adhering to the surface of the steel wire with clean water; (3), then dip-coat the surface of the steel wire with ammonium chloride or zinc chloride and other plating fluxes, and after drying, make the steel wire go through a bath where the zinc liquid is mel...
