A molten metal level measuring device in a continuous molten metal level measuring device uses temperature compensation. The device includes a cylindrical bobbin, a liquid level measuring unit helically wound around an outer surface of the bobbin, a circular inner cylinder in which the bobbin and the liquid level measuring part are located and which seals the bobbin and the liquid level measuring part from the outside and has the same axial direction as the bobbin, and a cylindrical protective tube in which the inner cylinder is located and which has the same axial direction as the bobbin and has one open end. Thermocouples extend axially in the space between the inner cylinder and the protective tube, and a control unit controls the liquid level measuring part to measure a liquid level of the molten metal based on the temperatures measured by the thermocouples.

Provided are a method and a system for a slag thickness detection and a slag-adding prediction. The method includes: acquiring real-time measurement data and real-time auxiliary data of a slag point on a surface of a protective slag layer of a casting mold; calculating a real-time slag thickness value corresponding to the slag point by using the real-time measurement data and the real-time auxiliary data of the slag point; and predicting a location on the surface of the protective slag layer where a slag-adding is to be performed and a slag-adding time when the slag-adding is to be performed based on a change in the real-time slag thickness value corresponding to the slag point by taking a preset slag thickness value as a reference.

Slide closure unit on the spout of a metallurgical vessel, preferably a copper-anode furnace, includes a housing in which refractory closure plates, as well as at least one connecting refractory inner casing, are arranged. A removable induction heater is provided, having at least one induction coil surrounding the refractory inner casing outside of the housing. In this way, it is possible to constantly keep the melt located in the outlet channel of the spout sufficiently warm so that it does not freeze before and/or during the pouring of the melt, or that any frozen metal and/or slag can be melted in the spout.

A flow rate measurement system being a flow rate measurement system that measures a flow rate of molten metal flowing through a hollow portion of a pipe includes an excitation coil that generates a magnetic field so as to intersect with the molten metal flowing through the hollow portion of the pipe; current supply processor circuitry that supplies an alternating exciting current to the excitation coil; a detector that detects a signal based on a magnetic field generated from the excitation coil by an alternating exciting current flowing through the excitation coil or a time variation in the magnetic field; and flow rate deriving processor circuitry that derives the flow rate of the molten metal based on the signal detected by the detector, wherein the pipe is arranged between the excitation coil and the detector, and a magnetic field that reaches the detector across the pipe is generated from the excitation coil.

Mould provided with a detection system of the level a liquid metal within a crystallizer of the mould in which the detection system is based on the transmission of at least one detection signal transmitted towards the crystallizer and a phase of reception of at least one received measuring signal dependent on the transmitted detection signal and mould and continuous casting machine provided with said mould.

Systems and methods are disclosed for an event detection system that captures data associated with events while a DC casting system forms an ingot, determines characteristics of the events, and improves the casting system based on the events. Example systems and methods may include initiating a casting operation using one or more pieces of equipment of a casting system including a casting apparatus; capturing sensor data associated with one or more acoustic signals captured relative to the one or more pieces of equipment performing the casting operation; comparing the sensor data with a set of acoustic profiles; determining whether a particular type of event has occurred; causing an adjustment to the casting system or to the casting operation based on whether the particular type of event has occurred; and initiating a second casting operation using the adjusted casting system or casting operation.

An apparatus for the continuous casting of metal products includes an ingot mold and a nozzle for feeding molten metal provided with at least one main outlet configured to direct the molten metal substantially toward the lower part of the ingot mold, and a plurality of secondary outlets configured to direct the molten metal substantially toward the lateral walls of the ingot mold.
