    • The present invention concerns a method for creating a thermally stable base structure which may form part of furnaces and means in connection with such a method. In particular, the present invention concerns base structures which may form part of ring furnaces for calcining of carbon blocks for use in aluminium electrolysis. The base structure rests on a foundation consisting of a number of columns (15, 16, 17, 18, 19, 20) and is created by a first layer B' of refractory bricks being laid on the foundation. These bricks are made with locking elements (25, 26) on their tops, onto which is laid a second layer C' of refractory bricks with equivalent, complementary locking elements underneath them. In this way, the two layers are connected to each other and a structure is achieved which has proved stable in relation to thermal and mechanical loads.
    • 本发明涉及一种用于产生热稳定的基础结构的方法,该基础结构可构成与这种方法有关的一部分炉子和装置。 特别地,本发明涉及可以形成用于煅烧用于铝电解的碳块的环形炉的一部分的基础结构。 该基础结构位于由许多列(15,16,17,18,19,20)组成的基础上,并由铺设在基础上的耐火砖的第一层B'制成。 这些砖由其顶部上的锁定元件(25,26)制成,在其上放置第二层耐火砖,其上具有相当的互补锁定元件。 以这种方式,两层彼此连接,并且实现了相对于热和机械负载稳定的结构。

    • The present invention concerns a wall structure and a method for constructing such an anchored wall structure. The wall structure is designed for use in a furnace or the similar, where the structure is exposed to cyclical thermal load. The structure consists of a row of individual elements which are placed in the longitudinal direction of the structure and are arranged in one or more courses, one resting on the other. The individual elements may consist of bricks of refractory material and the wall structure may also be provided with internal flue gas ducts. The wall structure is also designed to be able to compensate for longitudinal changes and any vertical changes as a consequence of cyclical thermal load. The wall structure's longitudinal changes are compensated for in a connection (2) arranged at least one end of the wall structure. The structure's individual elements are fixed to each other in the horizontal direction by means of mutually interacting contact elements. This produces a structure which remains stable after repeated thermal cycles, and costs related to restoration and stoppages can be reduced.
    • 本发明涉及一种用于构造这种锚固壁结构的壁结构和方法。 壁结构设计用于炉或类似物,其中结构暴露于周期性热负荷。 该结构由排列在结构的纵向方向上的一排单独元件组成,并排列成一个或多个平台,一个搁置在另一个上。 单个元件可以由耐火材料砖组成,并且壁结构还可以设置有内部烟道气管道。 壁结构还被设计成能够补偿由于循环热负荷而导致的纵向变化和任何垂直变化。 壁结构的纵向变化在布置在壁结构的至少一端的连接(2)中进行补偿。 结构的各个元件通过相互作用的接触元件在水平方向上彼此固定。 这产生在反复热循环后保持稳定的结构,并且可以减少与恢复和停止相关的成本。
