將5052鋁板軋輥用的鋼錠在反射爐中熔煉，并進(jìn)行半連續(xù)澆鑄。為了滿足冷軋嚴(yán)格厚度控制(5微米)的要求，金屬打撈的化學(xué)成分必須控制在限制范圍內(nèi)。這是由于化學(xué)成分的變化的大影響了在x射線測(cè)厚儀的輸出即為每一批,標(biāo)準(zhǔn)的價(jià)值(價(jià)值)的金屬x射線吸收計(jì)算基于金屬的化學(xué)成分,且計(jì)算值送入的式冷軋機(jī)厚度控制系統(tǒng)必要的補(bǔ)償。
　　The ingot for 5052 aluminum plate roll is melted in the reverberatory furnace and semi continuous casting is carried out. In order to meet the requirements of strict thickness control (5 μ m) in cold rolling, the chemical composition of metal fishing must be controlled within the limits. This is because the change of chemical composition greatly affects the output of the X-ray thickness gauge, that is, the standard value (value) of the metal X-ray absorption calculation is based on the chemical composition of the metal, and the calculated value is fed into the necessary compensation of the cold rolling mill thickness control system.

　　控制金屬的含氫量，消除熔煉和鑄造過(guò)程中的非金屬夾雜物，一直是鑄造工程師關(guān)注的主要問(wèn)題。圖2所示的在線脫氣過(guò)濾裝置是由鋁板制造商開(kāi)發(fā)的。將氬氣和氮?dú)饣旌虾螅D(zhuǎn)金屬中的正常氫氣濃度為0.15-0.20ml / 100g Al。鋁板制造商的實(shí)驗(yàn)室開(kāi)發(fā)了一種奇讀氣體分析儀。它已成功地用于該公司的在線脫氣和過(guò)濾系統(tǒng)。氣體分析儀是根據(jù)類似于Telegas儀器的熱物理原理設(shè)計(jì)的，并使用微處理器進(jìn)行計(jì)算。這些分析儀現(xiàn)在已經(jīng)可以在鋁板制造商之外的地方買到，并且得到了廣泛的應(yīng)用。
　　Controlling the hydrogen content of metal and eliminating the non-metallic inclusions in smelting and casting process are always the main concerns of foundry engineers. The on-line degassing filter shown in Figure 2 was developed by an aluminum plate manufacturer. After mixing argon and nitrogen, the normal hydrogen concentration in rotating metal is 0.15-0.20ml/100g al. A strange reading gas analyzer has been developed in the laboratory of aluminum plate manufacturer. It has been successfully used in the company's online degassing and filtration system. The gas analyzer is designed according to the thermophysical principle similar to that of the telegas instrument, and is calculated by microprocessor. These analyzers are now available outside the aluminum plate manufacturers and have been widely used.
　　為了消除或減少金屬熔體中的非金屬夾雜物，在線除氣器和過(guò)濾系統(tǒng)采用如圖3所示的多孔陶瓷管過(guò)濾器。過(guò)濾器可選用4個(gè)不同等級(jí)(孔隙率)的多孔陶瓷過(guò)濾器，如圖4所示，B類(Y—E類，有較厚的孔(非常細(xì)的孔)。根據(jù)板材的質(zhì)量要求來(lái)選擇陶瓷管的等級(jí)。通常使用中等孔隙率的C類陶瓷管，但D類陶瓷管孔隙率較細(xì)，除金屬夾雜物外，用于消除電腦盤毛坯。實(shí)踐表明，即使熔化金屬被過(guò)濾，金屬偶爾也會(huì)受到從過(guò)濾器結(jié)構(gòu)材料上脫落的微小耐火材料的污染。從這個(gè)冷的意思X說(shuō)，為了保證金屬的純度，避免夾雜污染，對(duì)流罐應(yīng)選擇合適的內(nèi)襯耐火材料。
　　In order to eliminate or reduce the non-metallic inclusions in the molten metal, the porous ceramic tube filter as shown in Figure 3 is used in the online degasser and filter system. Four porous ceramic filters of different grades (porosity) can be selected as the filter, as shown in Figure 4, class B (y-e, with relatively thick holes (very thin holes). According to the quality requirements of the plate, choose the grade of ceramic pipe. The medium porosity C-type ceramic tube is usually used, but the porosity of D-type ceramic tube is fine, which is used to eliminate the computer disk blank except for the metal inclusion. Practice shows that even if the molten metal is filtered, the metal will occasionally be polluted by the tiny refractory material falling off the filter structure material. In order to ensure the purity of the metal and avoid contamination by inclusions, the proper refractory lining should be selected for the convection tank.
　　為了生產(chǎn)出高質(zhì)量的陽(yáng)極氧化板，鋼錠的微觀組織和金相組織必須是細(xì)小而均勻的。在鑄造過(guò)程中，鋼錠表面附近的熔融金屬應(yīng)以盡可能深和均勻的速度冷卻。常用熱頂鑄造，將陶瓷纖維板貼附在鋼錠內(nèi)部，如圖所示。
　　In order to produce high quality anodized plate, the microstructure and metallographic structure of ingot must be fine and uniform. During casting, the molten metal near the ingot surface should be cooled as deep and uniform as possible. Commonly used hot top casting, ceramic fiberboard is attached to the inside of the ingot, as shown in the figure.
