Cooling Water Considerations in DC Casting

摘要

Cooling water quality in DC casting is critical (although by no means an exact science). The stability and repeatability of water flow, temperature, and chemical properties are important for the process and product quality. However, the relevance of system maintenance and water quality monitoring and control is often overlooked. Many of the water variables are eliminated if the available water can make a single pass through the system before being returned to the source. This ability is typically limited to primary plants located on fjords or large waterways, where the water is drawn directly from the source and returned after passing through the process. These large bodies of water have the added advantage of having stable and repeat-able temperature and quality levels, which complements the casting process.
