综述了控制钢液中铝含量的重要性，讨论了用于测定可溶性铝的各种方法，介绍了一种最近开发并获得专利的仪器，该仪器采用特殊电解池快速溶解固体钢样，还开发了一种计算机控制的流动注射分析仪（FIA），可直接产生%浓度的结果。重复测定的典型分析时间为150 s。在0.005 - 0.300%溶胶范围内，准确度范围为0.003 - 0.005%。钢中的铝
A review of the importance of controlling the aluminium content in liquid steel is made, and the various methods used for the determination of soluble aluminium are discussed.A recently developed and patented instrument, using a special electrolysis cell for rapid dissolution of the solid steel samples, and a computer‐controlled flow injection analyzer (FIA) also developed to produce results directly in % concentration, are described. Typical analysis time for duplicate determination is 150 s. Accuracy ranges from 0.003 to 0.005% in the range from 0.005 to 0.300% sol. aluminium in steel.
