摘要： A stave protection system for a metallurgical furnace comprises: a stave comprising a front face having an X direction and a Y direction which is perpendicular to the X direction such as to define an X-Y plane, the front face comprising rows of grooves which extend in the X direction; and inserts which are slidingly received by the grooves, the inserts so received by each respective groove being spaced apart from each other along the groove, the centres of the inserts which are received by one of the grooves being offset in each of the X and Y directions from the centres of the inserts which are received by an adjacent groove, each of the inserts projecting from the front face of the stave and comprising flow guiding surfaces which are inclined with respect to each of the X and Y directions in the X-Y plane, such that in use the offsets of the inserts in each of the X and Y directions and the inclined flow guiding surfaces cause a flow of furnace burden material, under gravity, to flow in a direction having a component in each of the X and Y directions, so as to distribute the burden material between the inserts over the front face of the stave and/or trap the burden material between the inserts.

摘要： Disclosed is a continuous casting nozzle having a refractory portion formed to contain a dolomite clinker and arranged to define a surface region adapted to be in contact with molten steel, which is capable of protecting a working surface of the nozzle from alumina build-up due to alumina in molten steel, while improving corrosion resistance, even during long-term continuous casting of molten steel. The refractory portion is prepared by adding a binder to a mixed material and subjecting the obtained mixture to kneading, forming and heat treatment. The mixed material comprises a dolomite clinker which has an average particle size of 0.8 mm or less and a CaO content of 50 mass % or less. The mixed material has a ratio W1/W2 of 0.33 or more, wherein W1 is a content by mass of CaO, and W2 is a content by mass of MgO. The mixed material comprises a dolomite clinker and a magnesia clinker. Alternatively, the mixed material comprises a dolomite clinker and a magnesia clinker. The mixed material has a ratio WD/WM in the range of 0.5 to 15, wherein WD is a mass % of dolomite clinker particles having a particle size of 1 mm or less in a particle size distribution of the dolomite clinker, and WM is a mass % of magnesia clinker particles having a particle size of 1 mm or less in a particle size distribution of the magnesia clinker. Further, the mixed material has a ratio W1/W2 in the range of 0.33 to 3.0, wherein W1 is a content by mass % of a CaO component in the dolomite clinker, and W2 is a content by mass % of an MgO component in the magnesia clinker.
摘要翻译：公开了一种连续铸造喷嘴，其具有形成为容纳白云石熟料并且布置成限定适于与钢水接触的表面区域的耐火部分，其能够保护喷嘴的工作表面免于氧化铝堆积，这是由于氧化铝在钢水中，同时提高耐腐蚀性，即使在钢水的长期连续铸造中也是如此。通过将粘合剂添加到混合材料中并对所得到的混合物进行捏合，成形和热处理来制备耐火材料部分。混合材料包括平均粒度为0.8mm以下且CaO含量为50质量％以下的白云石熟料。混合材料的W1 / W2比为0.33以上，W1为质量百分比，W2为MgO的质量含量。混合材料包括白云石熟料和氧化镁熟料。或者，混合材料包括白云石熟料和氧化镁熟料。混合材料的WD / WM比为0.5〜15，其中WD为白云石熟料的粒度分布中粒径为1mm以下的白云石熟料颗粒的质量％，WM为在氧化镁熟料的粒度分布中，粒径为1mm以下的氧化镁熟料粒子的质量％。此外，混合材料的比例W1 / W2在0.33〜3.0的范围内，其中，W1是白云石熟料中CaO成分的质量％，W2是MgO成分的质量％镁砂熟料

摘要： A device for adjustably positioning a structural element in a dust-laden environment, such as for positioning impact casing elements in a metallurgical blast furnace, consists of a motion rod connected between a drive member and the elements to be positioned and a shield through which the motion rod extends, the shield is constructed of plates which form a slot and of a slide movably positioned in the slot and having a bore through which the motion rod extends. The slide covers an opening through the plates and forms a closure against the passage of dust into the drive member. Further, the bore surface through the slide is shaped to afford not only longitudinal movement of the motion rod but also limited pivotal movement and, in addition, the slide affords transverse movement.
