摘要： A liquid metal/solid metal interface detecting device comprises in general a radiation source for generating gamma radiation, which is directed to pass through a strand extruded from a continuous casting mold. A detector detects the gamma radiation passing through the partially solidified strand to determine a spatial profile for a liquid metal/solid metal interface by relying on the different gamma radiation attenuation characteristics of the solid metal and the liquid metal. Preferably, the gamma radiation is at energies of greater than one million electron volts. In some embodiments, a movable support carries the radiation source and the detector and moves the radiation source and detector along and around the ingot enabling generation of a three-dimensional profile of the liquid metal/solid metal interface by utilizing tomographic imaging techniques. Alternatively, solidification at a single region is determined and this information is used to control the formation of the strand in process controller implementations. Surface temperature detectors can also be used to provide more information about the solidification.

摘要： An early indication of skin separation and expected thinning of the skin in a mold for continuous casting is provided by detecting the ratio of heat flow into the mold in two zones of limited width of the mold wall, one above the other and located where the skin is most likely to begin to separate. The resulting parameter K in conjunction with total heat flow Q into the zone is related to skin thickness s, generally, by the relation

wherein A'', B'' and C'' are constant parameters for the mold when operated at a constant casting speed. The total heat flow Q into the two zones is either determined directly by measuring temperature and coolant flow or indirectly by the relation

wherein A, B and C are additional parameters and To is the measured surface temperature of the ingot at the mold bottom opening. In the preferred form, the heat flow ratio is determined by temperature measurements in one cooling duct, traversing the mold side vertically.

摘要： A heat transfer coefficient α between a solidified shell (2) and a mold (4) sandwiching a mold flux layer (3), and a heat transfer coefficient β between a molten steel (1) and the solidified shell (2) are found by solving an inverse problem by using data from thermocouples (6), and a solidified shell thickness and a solidified shell temperature are estimated (solidified state in mold estimation amounts), and further, solidified state in mold evaluation amounts are obtained. It is determined whether a normal casting state or an abnormal casting state by comparing at least one or more kinds of amounts contained in the solidified state in mold estimation amounts and the solidified state in mold evaluation amounts with allowable limit values which are found based on at least one or more kinds of amounts contained in the solidified state in mold estimation amounts and the solidified state in mold evaluation amounts when the abnormal casting occurred in a past and stored in a data storage part.

摘要： The abnormality is detected during a flow thereof through the mold. The detection is achieved by means of at least a pair of upper and lower temperature detecting elements, located along the flow of the casting metal. The abnormality is determined to exist when a temperature inversion, that is T.sub.U .ltoreq.T.sub.L, takes place. The symbols T.sub.U and T.sub.L denote the temperatures measured by the upper and lower temperature detecting elements, respectively, in which a relationship, that is T.sub.U >T.sub.L, stands under a normal casting operation.
