板卷在熱軋過程中其表面易形成一層又脆又硬的氧化物，在進(jìn)行冷軋加工之前， 必須去除帶卷表面的氧化物，這一工序通常由酸洗機(jī)組來完成。酸洗生產(chǎn)線是我 公司較為成熟的技術(shù)，目前我們可為客戶提供；推拉式酸洗生產(chǎn)線（即半連續(xù)式 酸洗線）和連續(xù)式酸洗生產(chǎn)線。

A layer of brittle and hard ferric oxide will form on the surface of the steel strip during the hot rolling,and the ferric oxide layer will affect the surface quality of the strip during cold rolling.Pickling process is applied for removing the ferric oxide.We are professional in this technology,and we can provide the following kinds of pickling lines,Push-pull Pickling Line (Semi-continuous Pickling Line)and Continuous Pickling Line.

推拉式酸洗生產(chǎn)線 Push-pull Pickling Line

推拉式酸洗生產(chǎn)線是一種半連續(xù)式生產(chǎn)線，具有設(shè)備簡(jiǎn)單，適用帶鋼品種多、生 產(chǎn)消耗低、設(shè)備運(yùn)行故障少等特點(diǎn)。該機(jī)組適于年產(chǎn)量為10-60萬噸的生產(chǎn)。

Push-pull Pickling is a semi-continuous production line. It is characteristic with lower consumption,easier operation and fewer malfunctions,moreover it can pickle many kinds of incoming material. The line can produce 100,000-600,000 tons strip annually.

下表為年產(chǎn) 40 萬噸普通熱乳鋼帶推拉式酸洗生產(chǎn)線技術(shù)參數(shù) Following is the data for Push-pull Pickling hot rolled strip with the annual yield of 400,000 tons

連續(xù)式酸洗生產(chǎn)線 Continuous Pickling Line

連續(xù)式酸洗是帶鋼連續(xù)的通過盛有酸溶液的酸洗槽及清洗槽。它具有酸洗效率較高，產(chǎn)量大，耗電少等特點(diǎn)。該機(jī)組適于年產(chǎn)為60-100萬噸的生產(chǎn)。

Continuous Pickling is a production line that the steel strip is pulled continuously through the acid tank and rinsing tank.The line is characteristic with high efficiency and output and low electric consumption.The annual yield or the line is 600.000-1,000,000 tons.
