板卷在熱軋過(guò)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(lái)完成。酸洗生產(chǎn)線(xiàn)是我 公司較為成熟的技術(shù),目前我們可為客戶(hù)提供;推拉式酸洗生產(chǎn)線(xiàn)(即半連續(xù)式 酸洗線(xiàn))和連續(xù)式酸洗生產(chǎn)線(xiàn)。
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(xiàn) Push-pull Pickling Line
推拉式酸洗生產(chǎn)線(xiàn)是一種半連續(xù)式生產(chǎn)線(xiàn),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(wàn)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.
