금속을 반응성 용액에 노출시켜 금속의 온도를 낮추고, 예를 들어 재료를 제거하거나 재료를 첨가하여, 화학 반응을 통해 금속의 표면을 개질함으로써 금속을 처리하기 위한 기술이 기재되어 있다. 개시된 기술은 순수를 수반하는 종래의 냉각 기술에 비해 금속의 온도를 낮출 수 있는 속도를 유리하게 증가시킬 수 있고, 금속 제조 속도를 증가시킬 수 있고, 금속 제조 공정의 전체 복잡성을 감소시킬 수 있다. 개시된 기술은 또한 이용 가능한 표면 처리의 범위를 유리하게 확장시킬 수 있고, 더 빠른 표면 처리 공정을 가능하게 할 수 있고, 표면 처리 공정 동안 유해 화학 물질의 사용을 줄이거나 없앨 수 있다. 이러한 이점은 일어나거나 상승 온도에서 더 효율적으로 일어나는 화학 가공처리를 이용함으로써 발생할 수 있다. Described are techniques for treating metals by exposing the metals to reactive solutions to reduce a temperature of the metal and to modify a surface of the metal through chemical reaction, such as by removing material or adding material. The disclosed techniques may advantageously increase the rate at which the temperature of the metal may be reduced as compared to conventional cooling techniques involving pure water, increase metal manufacturing rates, and reduce overall complexity of a metal manufacturing process. The disclosed techniques may also advantageously expand the range of available surface treatments, allow for faster surface treatment processes, and reduce or eliminate the use of hazardous chemicals during a surface treatment process. Such advantages may arise by employing chemical processing that takes place or takes place more efficiently at elevated temperatures.
