Development of calculation methodology and creation of elements of metallurgical units - intermediate CCM ladles

The article considers questions connected with the estimation of serviceability of partitions and thresholds of intermediate CCM ladles. Some criteria of the device serviceability were accepted, such as durability, absence of cavitations and condition at which steel speed on the metal-slag border should be less than the proposed one. Dependences to calculate forces affecting the device as well as steel movement speeds on the metal-slag border were received analytically on the basis of famous expressions of mechanics of liquid, gas and hydraulics. The technique developed to calculate partitions and thresholds of intermediate CCM ladles will allow to calculate the minimum possible device sizes on account of the proposed function of steel refinement.
