    • White, chromium cast iron having shock and impact resistance which comprise iron together with:______________________________________ Carbon: 2.2 to 3.6% by weight Chromium: 12.0 to 30.0% by weight Molybdenum: 0.0 to 3.0% by weight Nickel: 0.0 to 3.0% by weight Manganese: 0.0 to 2.0% by weight Copper: 0.0 to 3.0% by weight Vanadium: 0.0 to 1.5% by weight ______________________________________ are disclosed. The casting are produced by casting the molten alloy in a metallic permanent mold, removing the solidified casting from the mold at a temperature above the A.sub.c3 temperature and cooling the casting sufficiently quickly to prevent the formation of pearlite as well as secondary carbide precipitation.

    • A device is provided for protecting the inner walls of casting molds, particularly molds of the permanent type which are filled by top pouring of the molten casting material thereinto, and for improving the surface quality of the castings formed in the mold. The device is formed from material which enables the device to be integrated into the casting formed in the mold and the protective device is configured with a bottom plate and a pair of laterally spaced upstanding side walls formed of sheet material. The protective device is placed in the bottom of the mold cavity and is located directly beneath the jet of molten casting material being poured into the mold. A wire lattice may be placed upon the protective device spaced above the bottom plate thereof or an upstanding tubular socket may be formed on the bottom plate.
    • 提供一种用于保护铸模的内壁的装置,特别是通过将熔融铸造材料顶部浇注而填充的永久型模具,以及用于改善在模具中形成的铸件的表面质量。 该装置由能够将装置集成到模具中形成的铸件的材料形成,并且保护装置构造有底板和由板材形成的一对横向间隔开的直立侧壁。 保护装置放置在模具腔的底部,并且位于浇注到模具中的熔融铸造材料射流的正下方。 线栅可以放置在与其底板间隔开的保护装置上,或者可以在底板上形成直立的管状插座。

    • An auxiliary device for use with a permanent mold in casting operations includes a cover plate having an upwardly and a downwardly facing surface. In place on the permanent mold, the downwardly facing surface defines the upper limit of the mold cavity. At least one pipe extends through an opening in the cover plate with its lower end in the plane of the downwardly facing surface of the cover plate. An annular recess located in one of the downwardly facing surface of the cover plate or the lower end of the pipe, encircles the lower end of the pipe radially outwardly from its opening. A breaking core can be incorporated as a part of the lower end of the pipe or it can be formed as a separate member. The pipe can be used only to feed additional molten metal into the mold as the poured metal starts to solidify or it can be used both to pour the molten metal into the mold cavity and then to provide the additional feed as the metal solidifies.
    • 用于铸造操作中的永久模具的辅助装置包括具有向上和向下的表面的盖板。 在永久模具上就位,面向下的表面限定了模腔的上限。 至少一个管道延伸穿过盖板中的开口,其下端在盖板的面向下的表面的平面中。 位于盖板的面向下的表面之一或管的下端中的一个环形凹槽围绕管的下端从其开口径向向外。 破碎芯可以作为管的下端的一部分结合,或者可以形成为单独的构件。 当浇注的金属开始固化时,该管可以仅用于将额外的熔融金属进料到模具中,或者可以将该熔融金属用于将熔融金属倒入模腔中,然后在金属固化时提供附加的进料。

    • A wall member for a converter chamber for the treatment of cast iron melt with magnesium. The size and shape of the wall member of a converter have a decisive influence on the efficiency of the treatment of a cast iron metal in a converter and on the accuracy of obtaining a residual magnesium content. For an optimum control of this influence, the length L of the wall member is determined in accordance with the formula L=600.times.T.sup.0.45 .times.A and the height H is determined in accordance with the formula H=0.5 L.times.A, wherein A is a coefficient ranging between 0.5 to 1.5 depending upon the sulfur content of 0.01 to 0.15% by weight and depending upon the thickness of the refractory lining of the converter vessel ranging from 40 to 150 mm.
    • 用于用镁处理铸铁熔体的转炉室的壁件。 转炉壁构件的尺寸和形状对转炉中铸铁金属的处理效率以及获得残余镁含量的准确性具有决定性的影响。 为了对该影响进行最佳控制,根据公式L = 600×T0.45×A确定壁构件的长度L,并且根据公式H = 0.5LxA确定高度H,其中A是范围在 0.5至1.5,这取决于硫含量为0.01至0.15重量%,并且取决于转炉容器的耐火衬里的厚度为40至150mm。
