Surface condition for the model of strand temperature field in the CCM secondary zone
Original language description
The main problem of the numerical simulation of solidifying billet in continuous casting process are not the algorithms themselves, but the correct determination of boundary conditions, especially surface conditions. Methods and devices including the robotized system for testing admission characteristics of water nozzles in the secondary cooling zone have been developed. Cooling nozzles are usually assessed through two types of characteristics. The ?cold? characteristics is the nozzle admission intensity and the ?hot? characteristics is heat transfer coefficient between cooled surface and surroundings. It was found that the cooling water pressure affects the hot and cold characteristics of nozzles both quantitatively and qualitatively. Relationships between water pressure and intensity of admission, heat transfer coefficient and shape of the characteristics were found. Measurements confirmed the step change of heat transfer coefficient at surface temperatures ranging from 400 to 600°C,
