摘要： The invention relates to a device for opening a pouring channel of metallurgical vessels such as foundry ladles or the like, wherein the pouring channel is arranged on the lined bottom of the vessel, comprising at least two slide plates (5, 7) which have a sliding shutter, comprising a fixed slide plate (5) connected to the vessel and at least one displaceable slide plate (7) operatively connected to same, wherein all slide plates (5, 7) have at least one pouring opening (6, 8) and can be displaced with respect to each other such that for opening and for the melt to flow out, the pouring openings (6, 8) are covered. In order to achieve a quality improvement by reducing the introduction of oxide into the tundish and moulds and hence an improvement in the cost-effectiveness, according to the invention, the need for sliding filling sand is completely removed by arranging a stopper (12) above the sliding shutter, the size of which exceeds the diameter of the pouring channel and which is connected to the lining of the vessel, and the sliding shutter has a gas supply line (10) to which pressurised gas can be applied such that the stopper (12) can be pneumatically removed from the closure position thereof to release the pouring channel.

摘要： The present invention relates to an apparatus for preventing nozzle clogging, which rapidly estimates the degree of nozzle clogging when molten steel is supplied from a tundish to a mold and then controls a casting state according to the estimation result, an apparatus for continuous casting having the same, a method for preventing nozzle clogging and a method for continuous casting using the same. The present invention includes measuring backpressure of inert gas supplied to a casting nozzle in real time; and calculating a nozzle status index from the measured actual backpressure. There are effects in that it is possible to rapidly and accurately estimate the location and degree of nozzle clogging based on a backpressure change of inert gas supplied to a casting nozzle, to detect leakage of the inert gas, and to improve a casting yield and quality of strands by suitably controlling inert gas supplied to a casting nozzle.

摘要： The object of the present invention is a refractory pouring tube including a contact face (15) capable of bearing against a contact face (11) of another refractory component (9), the said pouring tube being arranged to be displaced. The said pouring tube is characterised by the fact that its contact face (15) incorporates a cleaning groove (26, 27) delineated notably by a wall presenting an edge capable of exerting a scraping action, as the said pouring tube is displaced, at least partially on the determinate part of the contact face of the other refractory component. The cleaning groove makes it possible to preserve the integrity of the contact surface of the other refractory component and, consequently, the joint surface formed between the two components.

摘要： This invention relates to a gas blowing plate brick or nozzle brick for a molten metal ejector, characterized in that the plate brick or nozzle brick is divided into at least two segments in the horizontal direction with a plurality of small-diameter pipes arranged fixedly in a sealed state in the dividing surfaces. Each brick is capable of preventing the leakage of a gas blown into the above-mentioned kind of apparatus, and carrying out a stable casting operation, and renders it unnecessary to carry out troublesome, expensive additional steps, such as a brick cutting step, a brick boring step and a brick connecting step.

摘要： A collector nozzle (2) in a device for controlling outflow of cast steel from a ladle or from a tundish, which nozzle incorporates at least one main duct (7) placed ringwise round the outlet passage of the nozzle, a first plurality of secondary ducts (12) connecting each of the above main ducts (17) with a portion of said outlet passage and a second plurality of secondary ducts (13) connecting each of said main ducts (17) with the environment outside the nozzle, at the latter's lower end. The main ducts being filled with a current of inert gas under pressure so that the inert gas reaches the area of said passage where otherwise aluminium oxides would become deposited and immediately outside said nozzle to create overpressure of inert gas, thus preventing air from penetrating through the fissures between the nozzle and the tube protecting the flow of cast steel.
