摘要:
The floor of the invention comprises a plurality of structural elements (10) of elongated parallelepiped shape with their longitudinal axis horizontal, they being disposed adjacent to each other to form a flat horizontal structure supported by two opposing vertical walls (23) and (24) of the kiln; each structural element (10) comprises two internal beams (11) parallel to the axis of the element and a plurality of blocks (12) of thermally insulating material, each provided with two through holes (13) by which they are mounted along the internal beams (11); the blocks (12) are slidable along the internal beams (11); means also being provided acting on the ends of the row of said blocks (12) to compress the row in an axial direction, so pressing the blocks together; the internal beams (11) are stressed only partly by the weight of the blocks (12), which can therefore have a greater specific gravity or thickness to increase the insulating effect of the floor.
摘要:
Zur Erleichterung der Montage und Verbesserung der Stabilität sowie Vermeidung von mechanischen Beschädigungen an einer Decke (13) eines Industrieofens schlägt die Erfindung ein feuerfestes Profilteil zur Verwendung als ofenkanalseitig einsetzbares selbsttragendes Bauteil (20) vor.
摘要:
Die Erfindung betrifft ein Verbundsystem von feuerfesten keramischen Steinen zur Ausbildung einer gewölbeartigen Tragkonstruktion. Die Verbindung benachbarter Steine erfolgt über korrespondierende Profilierungen an den Aussenflächen der Steine in X- und Y-Richtung, wodurch es möglich ist, alle Steine innerhalb einer Lage, d.h. nebeneinander in X-Richtung und hintereinander in Y-Richtung, formschlüssig zu einer Tragkonstruktion anzuordnen. Daraus ergibt sich unmittelbar eine Stabilisierung der gesamten Trägkonstruktion.
摘要:
The invention relates to an electric arc furnace roof top (10) comprising a central portion (14) and a peripheral portion (16) surrounding the central portion (14), each of these portions having an inner surface (24,26) suitable for facing the furnace inner space (I). The inner surfaces of the peripheral and central portions form together a step (d) so as to raise the inner surface (24) of the central portion (14) in relation to the inner surface (26) of the peripheral portion (16) with respect to the furnace inner space.
摘要:
Furnace aggregate consisting of two sidewalls, ceiling formed by modules made of ceramic fiber mats, input and output gates, where this furnace aggregate, in direction from the input gate, is divided into pre-heating, firing and cooling zones. Sidewalls are in their lower parts formed by lines of alternately laid large-format ceramic blocks (1) equipped with vertical and horizontal interlocking joints, which have continuous openings (2). Above these lines of blocks (1) a labyrinth is created from both-sided interlocking sidewall stone (3) or interlocking plate (31) and above this labyrinth are again lines of blocks (1) placed alternately on each other. Outer sides of sidewalls are equipped with lining from insulation bricks (4) and covered by assembly mutually joint by refractory steel anchors and formed by ceramic fiber insulation (5), insulation plates (6) and outer encasement (7), which is in the cooling zone of the furnace equipped with the cooling system piping. Sidewalls are at their top edge equipped with refractory reinforcement (20) with interlock for settling the ceiling. Ceiling is formed by module assemblies allowing mutual connection consisting of ceramic fiber mats (10) equipped on their sides with interlocking joints and having in their bodies at least one puncture (11). Module assembly is formed by two modules of ceramic fiber mats (10) interlocked by interlocking joints mounted to at least one ceramic anchor (12). Ceramic fiber mats (10) and ceramic anchors (12) are horizontally traversed by at least one spike (13). Ceramic anchors (12) are led outside the ceramic fiber mats (10) by means of a head (14) adjusted for mounting the assembly to a welded structure from pressed profiles (15) located above each line of ceramic fiber mats (10) in direction of longitudinal axis of such line. Module assemblies have ends adjusted for settling to the interlocking joints on sidewalls reinforcement (20) of the furnace aggregate.
