    • A method for two-stage melt reduction of iron ore, in which iron ore is prereduced substantially to wustite and at the same time melted down in a melting cyclone, and then liquid hot metal is produced in an iron bath reactor connected to the outlet of the melting cyclone and receiving the melted wustite by adding carbonaceous fuels and oxidizing gas to the melt. The resulting reaction gas from the melt is afterburned, and the dust-laden, partly burned reaction gases from the iron bath reactor are accelerated and further afterburned by adding a hot blast with a temperature of 800.degree. C. to 1500.degree. C., and at least a portion of such accelerated, after burned reaction gases are introduced into the melting cyclone to reduce and melt fresh iron ore.
    • 一种铁矿石两阶段熔融还原的方法,其中将铁矿石基本上还原为方铁矿,同时在熔融旋流器中熔化,然后在连接到出口的铁浴反应器中产生液态铁水 熔融旋流器,并通过向熔体中加入碳质燃料和氧化气体来接收熔化的方钨矿。 来自熔体的所得反应气体被再燃烧,并且来自铁浴反应器的含灰尘的部分燃烧的反应气体通过在800℃至1500℃的温度下加入热风加速并进一步后燃,并且 将这种加速的,经过燃烧的反应气体的至少一部分引入熔融旋流器中以减少和熔化新鲜的铁矿石。

    • This invention relates to a method for installing a converter bottom, using not only bottom bricks of commercial brick formats but also shaped and fitting bricks, the largest area on a bottom plate being lined with bottom bricks of commercial brick formats, leaving a space free. After the bottom has been inserted into the converter, shaped bricks are laid one beside the other in the free edge area adjacent to the converter walling, the sides of these bricks facing the converter walling being fitted to the curvature of the converter walling. These shaped bricks are of a size such that a free space exceeding one joint width remains between each shaped brick and the adjacent bottom brick. Fitting bricks true to dimensions are laid in these free spaces.
    • 本发明涉及一种用于安装转炉底部的方法,不仅使用商业砖形式的底砖,而且还使用成形和装配的砖,底板上最大的区域衬有商业砖格式的底砖,留下空间。 在将底部插入转换器之后,成形砖在与转炉壁相邻的自由边缘区域中彼此靠近放置,这些砖的面向转炉壁的侧面装配在转炉壁的曲率上。 这些成形砖的尺寸使得在每个成形砖和相邻的底砖之间保留超过一个关节宽度的自由空间。 这些自由空间中放置了适合尺寸的贴砖。

    • A metering slide for fine-grained solids for gastight closing and cross-section-variable opening of vessels and piping in pneumatic conveying systems. A sliding plate provided with a metering opening is moved between two slide rings by a drive in a compression-proof slide casing. The intake side slide ring opening has a predetermined nominal width between 1/10 and 1/3 of the outside diameter of the slide ring. The discharge side slide ring has an inside diameter corresponding to 3 times to 10 times the nominal width of the intake. The slide casing is filled with a lubricant which is under a pressure equal to or higher than the operating pressure of the penumatic conveying system.
    • 用于气密闭合的细粒固体的计量滑块和气动输送系统中的容器和管道的横截面可变的打开。 设置有计量开口的滑动板通过在抗压滑动壳体中的驱动器在两个滑环之间移动。 进气侧滑环开口具有预定的标称宽度,该滑动环的滑动环的外径的1/10和1/3之间。 排出侧滑环的内径对应于入口标称宽度的3倍至10倍。 滑动壳体填充有等于或高于阴茎输送系统的操作压力的压力的润滑剂。
