Preheating type side-heating galvanizing furnace

Abstract

The invention relates to metal wire galvanizing equipment, in particular to a preheating type side-heating galvanizing furnace. According to the technical scheme provided by the invention, the preheating type side-heating galvanizing furnace comprises a furnace body and a zinc pot in the furnace body, wherein the end part of the furnace body is provided with a burner; flame paths are formed between the furnace body and the zinc pot; and flame is injected into the flame paths from the burner. The preheating type side-heating galvanizing furnace is characterized in that: first flame paths are arranged on two sides of the furnace body, a fourth flame path is formed on the first end of the furnace body, a second flame path is formed on the second end of the furnace body, and a third flame path is formed at the bottom of the furnace body; a preheating furnace body is arranged on the first end of the furnace body, and a preheating flame path is formed in the preheating furnace body; smoke generated by the flame passes through the first flame paths, the second flame path, the third flame path and the four flame path in turn and then is exhausted from the preheating flame path; and the burner is positioned on the first end of the furnace body. In the invention, the service life of the zinc pot is prolonged and energy is saved.

Description

technical field [0001] The invention relates to a device for galvanizing metal wires, in particular to a preheating type side heating 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] When galvanizing, the steel wire is firstly washed with alkaline liquid, and then the interstitial liquid on the surface of the steel wire is cleaned with water; then the steel wire is pickled with acidic liquid, and then the acidic acid adhered to the surface of the steel wire is washed away with water liquid; then dip-coat ammonium chloride flux on the surface of the steel wire, and after drying, make the steel wire pass through a zinc pot with zinc liquid melted therein to galvanize the steel wire. [0004] In the prior art, 1. The zinc pot is normally open. Since the solidification temp...

Problems solved by technology

[0004] In the prior art, 1. The zinc pot is normally open. Since the solidification temperature of zinc is 421°C, in order to ensure the normal galvanizing process, the temperature of the zinc bath should be maintained at 445°C~460°C, for This requires a high enough temperature to heat the zinc pot

2. The steel wire directly enters the zinc liquid without preheating, so zinc lumps will condense on the surface of the steel wire, affecting the speed and quality of galvanizing
