摘要： The invention describes a submerged sensor for use in a metallurgical vessel, such as a tundish. The sensor is positioned so that in use it is below a surface of a molten metal bath within the vessel. The sensor conveniently extends through the vessel wall and projects into the volume of the vessel. An upper end of the sensor is encased in a protective assembly. The protective assembly of the invention can be shaped so as to control the pattern of molten metal flow in the vessel or measure more accurately the molten metal exiting the vessel. Advantageously, the invention can combine the functionality required for flow pattern modification such as provided by a dam, impact pad or baffle, with the functionality required for a sensor. This combination reduces cost and complexity.

摘要： The present invention concerns a submerged entry nozzle for use in the continuous casting of liquid metal. The nozzle comprises a central bore and a plurality of pairs of discharge outlets. The cross-sectional area of the central bore decreases between pairs of discharge outlets, such that ratio of height to width of any outlet is one or less.

摘要： A tundish impact pad (1) for use in the continuous casting of molten metal is described that includes a base plate (2) having an upper impact surface surrounded, at least in part, by a sidewall (4) defining passageways. The impact pad is adpated to receive and deflect an incoming stream of molten metal, and permit outflow of the deflected stream through the passageways and the open top surface of the pad. Vaulted-stepped features (8, 9, 10) surrounding the passages and/or weir-like walls (4) assist directing the outflow. The division and distribution of the outflow facilitates the development of plug flow in the molten metal between the impact pad and the tundish outlet.

摘要： The present invention relates to a pour tube for casting molten metal. The pour tube is adapted to reduce turbulence and mold disturbances, thereby producing a more stable, uniform outflow. The pour tube includes an exit port with at least one tongue to provide at least two slots on either side of the tongue. The slots generate counter-rotating flows, which result in a more diffusive and more homogeneous outflow. Advantageously, such an outflow can reduce detrimental asymmetry and alumina clogging in the pour tube.

摘要： The present invention concerns stopper rod system for use in a metallurgical vessel, comprising a stopper rod and a nozzle. At least one of the stopper rod nose (42,56) and the internal surface of the nozzle bore comprise (43,62) a plurality of ripples that are arranged such that the size of a flow channel between the stopper rod nose and the internal stopper rod when the stopper rod system is in an open position discontinuously increases in size as a function of the distance downstream from the point of contact between the stopper rod and the nozzle.

摘要： The present invention relates to a metallurgical ladle and more particularly to the bottom of the ladle having an outlet through which the molten metal can drain. An object of the present invention is to increase the efficiency of a ladle draining operation, including reducing the amount of discarded metal, avoiding the premature flow of slag through the outlet, and reducing the contamination of slag in the molten metal effluent. The ladle bottom (2) comprises a plurality of terraces (31A) and flow channels(33A, 33B, 33C), ultimately directing the stream of molten metal to an outlet (5) of the ladle. The terraces are described as capturing slag and the channels permit molten metal to flow preferentially through the outlet.

摘要： An apparatus and method for detecting the condition of the flow of liquid metal in or from a teeming vessel includes one or more sensors for detecting vibration caused by a flow of liquid metal in or from the teeming vessel and for outputting a sensor signal corresponding to mechanical and acoustic vibrations detected by the sensor. A signal processor receives the sensor signal and compares the sensor signal to a reference calibration signal and outputs a comparison signal. A logic unit receives the comparison signal and outputs a status signal indicative of the condition of the flow of the liquid metal in or from the teeming vessel which can be used to stop the flow of metal. The calibration signal can be static or may be dynamically updated.
