将5052铝板轧辊用的钢锭在反射炉中熔炼，并进行半连续浇铸。为了满足冷轧严格厚度控制(5微米)的要求，金属打捞的化学成分必须控制在限制范围内。这是由于化学成分的变化的大影响了在x射线测厚仪的输出即为每一批,标准的价值(价值)的金属x射线吸收计算基于金属的化学成分,且计算值送入的式冷轧机厚度控制系统必要的补偿。
　　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.

　　控制金属的含氢量，消除熔炼和铸造过程中的非金属夹杂物，一直是铸造工程师关注的主要问题。图2所示的在线脱气过滤装置是由铝板制造商开发的。将氩气和氮气混合后，旋转金属中的正常氢气浓度为0.15-0.20ml / 100g Al。铝板制造商的实验室开发了一种奇读气体分析仪。它已成功地用于该公司的在线脱气和过滤系统。气体分析仪是根据类似于Telegas仪器的热物理原理设计的，并使用微处理器进行计算。这些分析仪现在已经可以在铝板制造商之外的地方买到，并且得到了广泛的应用。
　　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.
　　为了消除或减少金属熔体中的非金属夹杂物，在线除气器和过滤系统采用如图3所示的多孔陶瓷管过滤器。过滤器可选用4个不同等级(孔隙率)的多孔陶瓷过滤器，如图4所示，B类(Y—E类，有较厚的孔(非常细的孔)。根据板材的质量要求来选择陶瓷管的等级。通常使用中等孔隙率的C类陶瓷管，但D类陶瓷管孔隙率较细，除金属夹杂物外，用于消除电脑盘毛坯。实践表明，即使熔化金属被过滤，金属偶尔也会受到从过滤器结构材料上脱落的微小耐火材料的污染。从这个冷的意思X说，为了保证金属的纯度，避免夹杂污染，对流罐应选择合适的内衬耐火材料。
　　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.
　　为了生产出高质量的阳极氧化板，钢锭的微观组织和金相组织必须是细小而均匀的。在铸造过程中，钢锭表面附近的熔融金属应以尽可能深和均匀的速度冷却。常用热顶铸造，将陶瓷纤维板贴附在钢锭内部，如图所示。
　　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.
