摘要：

By measuring the grain size in samples taken from the casting furnace, the necessary amount of grain refiner can be calculated for each single cast. The Opticast method involves rapid sample preparation and grain size analysis, which allows the method to be used on-line in all cast houses. The grain sizes measured are compared against calibration curves and the optimum amount of addition is calculated. The method can also be used for production of ingots in any specified grain size range, within narrow limits. In practical application in two cast houses, cost savings of up to 90% have been accomplished for certain alloys, while the mean savings for the whole production is at least 50%. Due to decreased grain refiner additions considerable quality improvement has also been achieved.
