镀锌槽钢主要应用于各行业的金属构造设备上,主要是将除锈后的钢件浸入440~460℃左右消融的锌液中,使钢构件外表附着锌层,从而起到防腐的目的。这是一种有效的金属防腐方式,其运用特性主要有以下几点:

Galvanized channel steel is mainly used in metal structure equipment of various industries. The main purpose of galvanized channel steel is to immerse the rusted steel parts in the melting zinc solution at 440 ~ 460 (?) C, so that the surface of steel components is attached with zinc layer, thus playing the purpose of anti-corrosion. This is an effective way of metal anticorrosion. Its application characteristics are as follows:

(1)具有较厚的致密的纯锌层掩盖在钢铁外表上,它能够防止钢铁基体与任何的腐蚀溶液的接触,维护钢基体免受腐蚀。在普通大气中,锌层外表构成一层很薄而密实的氧化锌层外表,它很难溶于水,故对钢基体起着一定维护作用。假如氧化锌与大气中其它成分生成不溶性锌盐后,则防蚀作用更理想。

(1) Thicker and dense pure zinc layer is concealed on the surface of steel, which can prevent the contact between the steel matrix and any corrosion solution, and protect the steel matrix from corrosion. In the ordinary atmosphere, the zinc layer forms a very thin and dense zinc oxide layer, which is difficult to dissolve in water, so it plays a certain role in maintaining the steel matrix. If the insoluble zinc salt is formed between zinc oxide and other components in the atmosphere, the anticorrosion effect is better.

(2)具有铁—锌合金层,分离致密,在海洋性盐雾大气及工业性大气中表现特有抗腐蚀性。

(2) It has iron-zinc alloy layer, dense separation, and unique corrosion resistance in marine salt spray atmosphere and industrial atmosphere.

(3)由于分离结实,锌—铁互溶,具有很强的耐磨性。

(3) Because of separation and solidification, zinc-iron is soluble and has strong wear resistance.

(4)由于锌具有良好的延展性,其合金层与钢基附着结实,因而热镀件可停止冷冲、轧制、拉丝、弯曲等各种成型而不损坏镀层。

(4) Because zinc has good ductility and its alloy layer adheres to the steel base, hot-dip parts can stop cold stamping, rolling, wire drawing and bending without damaging the coating.

(5)钢构造件热镀锌后,相当于一次退火处置,能有效改善钢基体的机械性能,消弭钢件成型焊接时的应力,有利于对钢构造件停止车削加工。

(5) After hot-dip galvanizing, the mechanical properties of the steel matrix can be effectively improved, the stress of the steel parts during forming and welding can be eliminated, and the turning process of the steel structures can be stopped.

(6)热镀锌后的件外表光亮美观。

(6) Hot-dip galvanized parts have a bright and beautiful appearance.

(7)纯锌层是热镀锌中富有塑性的一层镀锌层,其性质根本接近于纯锌,具有延展性,所以它富于挠性。

(7) Pure zinc coating is the most plastic one in hot-dip galvanizing. Its properties are basically similar to pure zinc and it has ductility, so it is flexible.
