Steel wire galvanization method and galvanization device used in steel wire galvanization method

Abstract

The invention provides a steel wire galvanization method and a galvanization device used in the steel wire galvanization method. According to the steel wire galvanization method, during rare earth adding in the galvanization process, rare earth is immersed in a galvanization pond through a rare earth adding device, the rare earth adding device is detachably connected to the galvanization pond, therare earth adding device prevents rare earth floating, and in the galvanization process, rare earth seeps out of reserved seepage holes through the rare earth adding device. Through the rare earth adding device, the rare earth is added in galvanization liquid, rare earth floating is prevented, the rare earth utilization rate is increased, the galvanized steel wire surface finish degree is high, and accumulated knots are avoided. Through the device, timely rare earth supplementing is convenient, an installing inserting rod can directly downwards move, then the installing inserting rod and a rare earth container can be taken out, after rare earth filling, the installing inserting rod is installed and arranged in a casing pipe in a sleeved manner so that rare earth metal can be continuouslysupplemented into zinc liquid, the structure design is simple and reasonable, usage is convenient, and very high practicability is achieved.

Description

Technical field [0001] The invention relates to the field of steel wire galvanizing, in particular to a steel wire galvanizing method and a galvanizing device used in the same. Background technique [0002] The traditional hot-dip galvanizing production line adds zinc-aluminum-rare-earth alloy block (ie Zn-0.2%Al-RE) to the zinc pot to form an alloy coating on the surface of the steel wire. This traditional process is prone to leakage and thick coating, and The coating is not easy to fall off, and the corrosion resistance is weak. The current domestic galvanizing process for steel wire is mainly to add 55% of zinc-aluminum alloy / pure zinc to the plating solution. This method has low cost, but the steel wire has a poor surface finish. The buildup is generated, and rare earths are added in the smelting process of zinc aluminum alloy later. After adding 5% of zinc aluminum alloy containing rare earth to the plating solution, the galvanizing effect is good, the surface is smooth, but...
