A method for optimizing the position of a plurality of containers in a block, including at least one crane configured to move the containers is provided. A crane control unit (CCU) is provided in which the following steps are performed: identifying a selected container to be moved from a current position CP within a sub-section of said block to a new position NP within the sub-section; calculating a number of container moves required facilitating the move of the selected container in previous step; arranging the required number of container moves in a queue for each crane; and performing the container moves as arranged in the queue by controlling said at least one crane. Also provided is a computer program, a computer-readable medium encoded with the computer program, and a system for optimizing the position of a plurality of containers in a block.

An air-core reactor with natural-air cooling of a winding includes first open spaces to let air flow through the winding in parallel with an axis of symmetry of the reactor and second open spaces crossing the first open spaces to let air flow through the winding angular to the axis of symmetry. A ventilation unit to produce a forced-air flow is arranged in such a way to the air-core reactor that a first part of the forced-air flow enters one of the first or second open spaces and at least one guiding element is arranged with respect to the crossing of the first and the second open spaces in such a way that the first part of the forced-air flow leaves and a second part of the forced-air flow enters the one of the first or second open spaces. A shielding element is arranged at another crossing of the first and the second open spaces so that substantially no air can leave or enter the one of the first or second open spaces.

A control system for regulating the flow of liquid metal in a device for casting a metal. A detector measures a process variable. A control unit evaluates data from the detector. At least one process parameter is automatically varied in order to optimize casting conditions. The detector measures a characteristic of the meniscus at at least two points on the meniscus instantaneously throughout the casting process.
