The main production goal for Horizontal Direct Chill (HDC) ingot production is to increase the process duration to produce different alloys in an economical way. At the same time the product quality (metallurgical, ingot shape and packaging) has to be continuously improved. The process itself can be divided into four main steps: melting and alloying, melt treatment, casting and then sawing and packaging. Disturbances to just one of these steps can lead to abort of the full process and therefore loss of production. One of the main issues can be nozzle clogging and therefore the rapid loss of strands. Since SOP (2015) of our 2nd horizontal continuous casting plant, different set-ups and parameters were tested to decrease nozzle clogging and to increase the process duration: including diverse material mixes (sows and liquid metal), furnace and metal temperature, metal treatments (Cl/Ar degassing, CFF Filters) and ending chronologically with the launder set-up (dimensional stability) and also flux addition. This paper gives an overview of the tested parameters during ramp-up.
