摘要： A method of analyzing water in a continuous casting process and controlling chemical addition to the water may involve measuring, with a plurality of sensors, at least one characteristic of a water in a plurality of different locations of a water recycle system for the continuous casting process. The continuous casting process can have multiple spray nozzles that spray water on a metal being cast, and the water recycle system may include a gravity settling tank, a filter, and a cooling tower. A processor can determine, using the measured at least one characteristic of the water from the plurality of sensors, a composite water quality value for the water in the water recycle system. A chemical additive can be controllably added into the water recycle system based on the determine composite water quality value.

摘要： Monitoring of a line system (1) in which a liquid medium (3) is guided in a line (2). The current pressure of the liquid medium (3) in the line (2) and in the associated current flow are sensed at sensing times. The two values are fed to a computing unit (5). The computing unit (5) calculates a theoretical flow of the liquid medium (3) in the line (2) from the sensed current pressure by taking into account a specified flow function. The flow function describes a physical relationship between the theoretical flow of the liquid medium (3) and the current pressure of the liquid medium (3). The computing unit (5) determines an individual degree of clogging on the basis of the current flow and the theoretical flow. On the basis of a number of determined individual degrees of clogging and by using stochastic methods, the computing unit (5) calculates an interval within which a degree of clogging of the line system (1) lies with a probability to be defined. The line system (1) is monitored by using the size of the interval and/or the position of the interval with respect to first limits for the degree of clogging that are defined beforehand.

摘要： A method of casting a metal ingot having the steps of delivering molten metal to a direct chill mold, forming a solidified shell of metal, applying a coolant to a surface of the shell as it emerges from the mold, and withdrawing a solidified ingot from the mold. The coolant contains an oxidation inhibitor for increasing the rate of heat transfer from the solidifying metal compared to a coolant not containing the oxidation inhibitor to produce an ingot which is resistant to cracking.

摘要： Continuously-cast lithium-containing alloy ingots are produced by a direct chill process including cooling the alloy to form a continuous ingot having a solid shell and further cooling the ingot by direct chill with an organic coolant. The organic coolant in one aspect includes a modified hydrocarbon fluid, e.g., ethylene glycol, having less than a predetermined moisture content. The method includes recirculating coolant while controlling moisture content. An ingot formed by the present invention provides small dendrite arm spacing in a relatively large size ingot. Aircraft plate or sheet is produced from the ingot of the present invention.
