A container for molten metal is provided with a temperature measuring device arranged in an opening of a container wall. The temperature measuring device has a protective sheath, which projects into the container and which is closed at its end arranged in the container. A temperature measuring element is arranged in an opening of the protective sheath. The protective sheath is composed of a mixture of a heat-resistant metal oxide and graphite, and the closed end is spaced at least 50 mm from the container wall.

A device and a method are provided for measuring the moisture in die cast molds, the cavity of which is connected via an evacuation conduit to an evacuation device. The modular assembly of the device is connectable to the evacuation conduit and includes a sensor assembly to measure the moisture of gases evacuated from the mold cavity. The sensor assembly includes an emitter emitting electromagnetic radiation and a detector detecting electromagnetic radiation. On the basis of the measured values obtained during the evacuation action it can be determined whether the amount of a water/release agent mixture jetted into the mold cavity needs to be altered before the actual casting action.

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.

A method, device and apparatus are provided for measuring the temperature of a melt, particularly of a molten metal, with an optical fiber, fed into the melt through a disposable guiding tube. The optical fiber and an immersion end of the tube are immersed into the melt and have feeding speeds which are independent from each other. An elastic plug is arranged within the tube or at an end of the tube opposite the immersion end. The optical fiber is fed through the elastic plug, and the elastic plug reduces a gap between the optical fiber and the tube, which has a larger inner diameter than the outer diameter of the optical fiber. The apparatus includes a fiber coil and a feeding mechanism for feeding the optical fiber and the tube, including at least two independent feeding motors, one for feeding the optical fiber and one for feeding the tube.

A gas purging plug for blowing gas into a metallurgical vessel, having the form of an elongated body made of a first refractory material, contains a final visual wear indicator in the form of an elongated core extending from an inlet end to a distance, along a central longitudinal axis, less than the length of the elongated body. The final visual wear indicator is made of a second refractory material that differs in visual appearance from the first refractory material between 800 and 1500 degrees C. The plug also contains an intermediate visual wear indicator extending from the inlet end to a point between the end of the final visual wear indicator and the opposite end of the elongated body. The intermediate visual wear indicator is made of a third refractory material that differs in visual appearance from the first and second refractory materials between 800 and 1500 degrees C.

The invention relates to a method of casting a metal alloy ingot. The method includes providing an on one side open-ended mould having a mould cavity, positioning the open-ended mould such that the mould opening points side-wards or down-wards, providing a casting container with an upwardly positioned aperture, and filling said casting container with molten metal for one casting operation. The method also includes locating the casting container below the mould while the mould opening points side-wards or down-wards, and rotating the mould together with the casting container to a position whereby the mould opening points upwards such that the molten metal is conveyed into the open-ended mould until a desired thickness. Molten metal in the open-ended mould is cooled directionally through its thickness where the solidification front remains substantially monoaxial.
