Embodiment Construction
[0017] According to the furnace lining structure and service temperature, the present invention breaks the internal anchoring structure of the traditional module, puts the compressed and packaged module outside with a metal anchoring fork and inserts it from the side, and at the same time moves its fixing position from the center to the outside of the module along the horizontal line to the right , so that the whole process of nut fixing is visualized, and the center sleeve and installation guide tube are abandoned, which is convenient for installation and inspection, reduces labor and material consumption, shortens the installation cycle to a limited extent, and significantly improves economic benefits.
[0018] See Figure 1 to Figure 3 ,
[0019] Construction steps:
[0020] Module assembly: combine the packaged fiber module made in the ceramic fiber manufacturer with the custom-made "fork" shaped metal anchor fork. The metal anchoring fork includes a head that is folded ...

The invention relates to a ceramic fiber module for an annealing furnace lining, in particular to an ectopic fixation method of ceramic fiber modules for an annealing furnace lining. The method comprises the steps of module assembling, wherein the fiber modules made and packaged in a plant are combined with processed and customized metal fork-shaped anchoring structures; anchoring bolt welding, wherein the ectopic positions of anchoring bolts are determined through measuring and setting-out, and the anchoring bolts are firmly welded; backing fiber blanket paving, wherein backing fiber blankets are paved in a butt-joint mode; fiber module installing, wherein the fiber modules are installed in place according to the installation numbers; nut screwing, wherein on the outer sides of the modules, metal anchoring fork opening portions are sleeved with the anchoring bolts to be close to the modules, then clamp-type gaskets are fixed to the metal forks, and finally nuts are installed on the anchoring bolts and tightened; the process is conducted circularly until installation of the row of modules is finished; a transverse package belt is disassembled, wood splints are pulled out, and the surfaces of the modules are flattened with a wood float. According to the fixation method, usage of metal fixation parts, plastic casing pipes and the like is reduced, the method is convenient to operate and reliable, and the working efficiency is improved.
Description
technical field [0001] The invention relates to an annealing furnace, in particular to a ceramic fiber module for the lining of the annealing furnace. Background technique [0002] With the increasingly higher requirements for energy saving, emission reduction and environmental protection, the lining of annealing furnaces in the metallurgical industry, especially the furnace roof and furnace wall, adopts refractory ceramic fiber module structure. Compared with the previous lining structure, the ceramic fiber module lining has low heat capacity, It has good thermal shock resistance and better heat insulation performance, which can effectively strengthen the heat insulation effect of the furnace lining and reduce the heat loss of various thermal equipment. [0003] The arrangement structure of traditional ceramic fiber modules is mostly in a row or mosaic style, and the fiber modules are mostly hung in the center hole. The installation procedure is anchor bolt welding, inspect...
