Embodiment
Set up channel-section steel in steel column 9 upper ends, the regenerator left and right sides and do and hang that the gap between some secondary beam 7, two secondary beams of crossbearer is slightly larger than the suspension rod diameter between 8, two girders of arch special-purpose steel structure girder, with secondary beam electric welding anti-sliding stop on girder.For the arch top that thermal insulation layer is arranged, remove aluminium foil above the arch brick and insulating cotton, the first layer insulating brick, second layer insulating brick etc. successively, certain interval of time slowly descends arch brick surface temperature between each step.The arch brick will cool off contraction after removing thermal insulation layer, be the danger that reduces to construct, and the tie rod between the steel column of the regenerator left and right sides is strained.Determine that according to field condition the drill bit with suitable dimension and material punches in the middle of each piece arch brick 16 upper surface of sunken regions, in the punching process drill bit is carried out the part cooling, and avoid undue force that original arch top refractory brick is hit down.The expansion bolt 2 of punching back mounting strap drop hanger in the hole, the diameter of expansion bolt is between 5mm-20mm.And then connect drop hanger and suspension rods 4 with iron chains 3, and the suspension rod the other end passes the gap between the secondary beam, and the upper end screws on hangs nut suspender is suspended on the secondary beam 7.At this moment, suspender just is in place and does not tighten, wait an arch brick that all sinks all hung after unified again pretension, stressed all even to guarantee arch top integral body by the Harmony of maintenance position.After maintenance construction finishes, for preventing that arch brick surface temperature from raising expansion bolt is come off, at the logical certain cooling air in chain, drop hanger and the arch brick junction on arch top, for preventing that cooling air from making arch brick surface crackle occur, apply on the brick face with an amount of refractory mortar, refractory mortar or other plasticity-refractory body, thickness is 1-5mm.Tighten one by one and hang nut 5 (will use the tension force spanner generally speaking, prevent firmly inequality or tension), hang the arch end-of-job.Will make regular check on later on, discovery suspender degree of tightness differs and just need readjust, the pulling force that will make the arch top be subjected to evenly making progress in a word.
At different sinking degree, can select different sequences of construction.Sink early stage or mid-term on the arch top, construct, progressively to the most dangerous position development, to guarantee whole stability in arch top and the risk that reduces in the possible construction generally preferably from the arch angle.Sink the later stage on the arch top, when the possibility increase of local collapse took place, construction was general preferably from the weakest link gently, the development of progressively peritropous position, the one, when avoiding the periphery construction, because small vibrations cause subsiding of the weakest link arch brick; The 2nd, if the weakest link arch brick subsides, reduce its generating capacity as far as possible and enough goods and materials are arranged and the preparation of strength, carry out emergent management.
The present invention is with cheaper material and construction cost, in regenerator crown top local subsidence but hang maintenance before not caving in, thoroughly solves the hidden danger that the arch top sinks may cause that the arch top caves in, and guarantees the operation of tank furnace stability and safety, prolongs regenerator work-ing life.
