    • A low carbon high chromium alloyed steel is made by an underpressure treatment wherein a steel melt with a high chromium and carbon content is supplied with a gaseous decarbonization agent while it is maintained at an underpressure. At the beginning of the underpressure treatment the steel flows upwardly from a ladle through an inlet into a reaction vessel and no decarbonization agent is supplied. In a second phase of the treatment a high quantity of decarbonization agent is added directly to the melt which flows upwardly from the ladle into the reaction vessel. In a third treatment phase a small quantity of decarbonization is supplied. The melt is subsequently deoxidized and alloy corrected and it is then poured off from the reaction vessel. The apparatus includes a reaction vessel which has a downwardly extending inlet connected to the ladle and an outlet spaced from the inlet extending down into the ladle within the melt thereof. The inlet includes means for directing a decarbonization agent directly into the inflowing melt at the inlet. The apparatus includes a downwardly extending oxygen blow lance which is sealed at its entrance into the top of the vessel and which is water cooled by a surrounding water cooling jacket system. The vessel also includes an inlet for additional alloy materials.
    • 通过负压处理制造低碳高铬合金钢,其中具有高铬和碳含量的钢熔体在维持在负压下被供给气态脱碳剂。 在负压处理开始时,钢从浇包通过入口向上流入反应容器中,并且不提供脱碳剂。 在第二阶段的处理中,将大量脱碳剂直接加入到从浇包向上流入反应容器的熔体中。 在第三处理阶段,提供少量脱碳。 然后将熔体脱氧并合并校正,然后将其从反应容器中倒出。 该装置包括反应容器,该反应容器具有连接到钢包的向下延伸的入口,以及与在其熔体内向下延伸到钢包中的入口间隔开的出口。 入口包括用于将脱碳剂直接引入入口处的流入熔体的装置。 该装置包括一个向下延伸的氧气喷枪,其在其入口处密封在容器的顶部,并且由周围的水冷套管系统水冷却。 该容器还包括用于附加合金材料的入口。

    • A bearing device includes at least one kingpin, a carrier unit, a first bearing unit, and a second bearing unit. The first and second bearing units rotatably support the carrier unit relative to the kingpin. The first bearing unit includes an angular contact sliding bearing that includes a first bearing element, a second bearing element and a third bearing element, the first and second bearing elements being movable relative to each other during at least one operating process, and the third bearing element being disposed between the first bearing element and the second bearing element. During the operating process the third bearing element slides on the first and/or second bearing element, and the third bearing element is formed at least partially from a polymer.
