Description

【発明の詳細な説明】 本発明は、特許請求の範囲第１項に記載の概念における
溶鉱炉あるいは鋳鍋からの溶解金属を通す低部流出口に
使用する装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for use in a lower outlet for passing molten metal from a blast furnace or a cast pot in the concept defined in claim 1.

本発明に従った装置がそれのために使用する。A device according to the invention is used for that purpose.

鉱流において酸素。There is always a demand for higher purity for metals, including iron. However, when pouring molten metal from a blast furnace or similar into a casting pot, or from a casting pot into a mold, the molten metal stream is exposed to the atmosphere, so that the molten metal is exposed to oxygen in the molten stream.

溶解金属を底部から取り出す方法が公知である。These elements or their compounds, including nitrogen and hydrogen, degrade the purity of the molten metal; this degradation can be limited by shortening the pouring time and pouring path. In this regard, methods are known in which the molten metal from a blast furnace or cast pot is removed from the bottom.

第８１２２１６号）、この方法はその実施可能性と経済
性から小規模の装置に限定されている。Although it is known (UK Patent No. 812,216) to protect the melt flow from atmospheric influences by arranging the blast furnace and the casting pot in a closed space excluded from air or immersed in a protective gas, this method is limited to small scale equipment due to its feasibility and economy.

、結果としてより長い流出口を有することになる。Therefore, methods for protecting the melt flow from atmospheric influences are limited to methods that shorten the melt flow and casting time through bottom outlets. At the same time, reducing the pouring time of molten metal from the blast furnace requires lower temperatures, resulting in a reduction in overall loading time and at the same time energy savings. Despite this advantage, known bottom outlet devices have a few drawbacks. This is because such devices are actuated by flaps, which open and close the opening of the bottom outlet using pneumatic or hydraulic cylinders, during which the progress of the melt and the metallurgical work are interrupted. The static pressure of the molten metal is applied to a pneumatic or hydraulic device via the flap and its associated rod. Therefore, irregularities in the pneumatic or hydraulic mechanism of this bottom outlet device can cause disturbances during the loading time and during the outflow and lead to considerable damage, which is also due to its working method. It requires a certain spacing between the individual mechanical devices, resulting in a longer outlet.

確実に耐えることができず、そのために底部の流出口の
閉鎖は短時間しかできない。In the above-mentioned known device (GB 812,216), there is a closing plate in the melting crucible of the blast furnace, which avoids transmission of the static pressure of the molten metal by pneumatic or hydraulic mechanisms. This closure plate mechanically supports the static pressure of the molten metal and is actuated by the hand wheel via a pivot shaft and bevel gear. The disadvantage of this closure plate is that the mouth of the outlet opening at the bottom of the melting crucible must be made very small to prevent the molten metal from flowing out. This cannot reliably withstand large and constantly changing temperature loads on the closure plate, so that the bottom outlet can only be closed for a short time.

A device for use in a lower outlet for molten metal from a blast furnace or a casting pot according to the concept according to claim 1, which operates reliably and withstands greater mechanical and thermal loads and is maintenance-free. It is an invention based on the task of creating.

いは表面を粗くしである。The particulate material fills the outlet opening or a portion thereof. The plate prevents the downward flow of particulate matter, takes on the static pressure of the molten metal, and is placed directly below the mouth of the outlet opening. To open and close the outlet, the plate slides or pivots horizontally. In order to ensure the necessary movement of the plate, the upper corner of the plate has a distance of 2 to 15 mm from the lower corner of the mouth of the outlet opening, preferably 5 to 8 mm. It depends on the grain spacing of the granules. This ensures that no particulate matter flows out of the closed outlet opening when the diameter of the plate is two to three times or more than the diameter of the outlet. Additionally, the plate may have recesses or a roughened surface.

一一一高にその特徴がある。To open the outlet opening, the plate can simply be removed from its mouth, so that the particulates either fall out of the outlet opening or are forced out by the static pressure of the molten metal, causing the molten metal to can flow out. The plate moves in a straight line on a guide rail connected to the blast furnace or casting pot.

In the case of repair work in the area of the device at the bottom outlet, it can be fixed with split bolts.

いうことに注意すべきである。It is surprising that the device according to the invention completely protects the melt stream from atmospheric influences during discharge without any economic waste. This is due to the fact that as the plate moves out of the outlet opening, the protective tube enters or pivots and connects the plate with the melt flow, so that the M'jJJ of the plate requires additional operations or This method does not require any special maneuvering. It should be noted that in the end position of the common drive for the plate and the protective tube, the axis of the latter and the axis of the outlet opening overlap.
