Abstract
The invention discloses the method for repairing and assembling of the vaporization gas hood of converter vaporization cooling boiler, step is: 1. according to the technical requirements of design or drawing, the straight tube of mini three links Guan Yiduan is not reserved fitting allowance, directly welds mutually with circular header; 2. with circular header horizontal positioned on the ground, the axis of mini three links pipe is in vertical direction, and the straight tube of mini three links Guan Yiduan welds mutually with circular header; 3. two of the mini three links pipe the other end breeches pipes weld with comb respectively.Method of repairing and assembling of the present invention, mini three links are assembled under the situation of not putting fitting allowance, reduce waste of material, save material and the energy; Header lies in a horizontal plane in ground, more can control fitted position on the ground well, and the assembling moulding is attractive in appearance, not limited by the operating space, has eliminated the existing security incident of aerial work; The welder can carry out the welding of comprehensive planimetric position, reduces each work post work holdup situation and guarantees weldquality, improves efficiency of assembling.
Description
Technical field
The present invention relates to a kind of method of repairing and assembling of steel-making converter vaporization cooling boiler, especially the method for repairing and assembling of the vaporization gas hood of steel-making converter vaporization cooling boiler.
Background technology
Converter vaporization cooling boiler occupies crucial status at steelworks, and it not only is used for reclaiming coal gas, steam and flue dust, and participates in STEELMAKING PRODUCTION directly as the part of converter steelmaking process.When bessemerizing, a large amount of high-temperature flue gas pass waste heat boiler, and the thermal load of waste heat boiler sharply increases; When blowing stopped, the thermal load of waste heat boiler sharply reduced, and converter flue vaporization refrigerative running condition with converter smelting process periodically, change sharp must exert an influence to the flue refrigerative of vaporizing in abominable operational conditions work-ing life.Therefore the work-ing life of converter evaporation cooling air flue is very short, flue fire door section mean life is 4～6 months, needs maintenance in 1 year, maintenance back assembling several times, under the prerequisite that guarantees the maintenance assembly quality, shorten the time of evaporated flue fire door section maintenance assembling, to improving output of steel, safety in production has significance.
What the vaporization gas hood of steelworks 50t converter vaporization cooling boiler was the most complicated is the fire door section; Form by 156 Φ 38*5 steel pipes, be connected with circular header through 78 mini three links pipes.The assembling of medium and small Y-tube of prior art and header is to set up at the petticoat pipe mounting rack, and circular header is standing after the support location, just assembles.There is the problem of five aspects in this assembly method: 1, straight tube of mini three links must be put fitting allowance, i.e. waste material; 2, the mini three links assembling is one, welds one, causes the work holdup between each work post, the cost of labor height, and efficiency of assembling is low; 3, on the high chain-wales of the 1-2 rice of setting up, assemble, because the place restriction is second-rate; 4, the welding position is undesirable, forms all position welding, has increased the welding difficulty; 5, aerial work can increase the generation of security incident.
Summary of the invention
The vaporization gas hood that the present invention is directed to the converter vaporization cooling boiler of prior art overhauls laggard luggage and joins above shortcomings, provides a kind of assembling and positioning accurately, not to be subjected to operating space restriction, improves efficiency of assembling, reduces the method for repairing and assembling of vaporization gas hood of the converter vaporization cooling boiler of the cost of overhaul.
Technical scheme of the present invention is: the method for repairing and assembling of the vaporization gas hood of converter vaporization cooling boiler is characterized in that comprising the steps:
1, according to the technical requirements of design or drawing, the straight tube of mini three links Guan Yiduan is not reserved fitting allowance, directly welds mutually with circular header;
2, with circular header horizontal positioned on the ground, the axis of mini three links pipe is in vertical direction, and the straight tube of mini three links Guan Yiduan welds mutually with circular header;
3, two of the mini three links pipe the other end breeches pipes weld with comb respectively.
The method of repairing and assembling of the vaporization gas hood of converter vaporization cooling boiler of the present invention with respect to prior art, has following characteristics:
1, straight tube of mini three links is assembled under the situation of not putting fitting allowance, reduces waste of material, saves material and the energy.
2, on the ground, under this advantageous conditions in ground, more can control fitted position well, the assembling moulding is attractive in appearance, not limited by the operating space with circular header horizontal positioned; At Ground Operation, eliminated the existing security incident of aerial work.
3, after the whole assemblings of riveter were finished, the welder just can carry out the welding of comprehensive planimetric position, reduced work holdup situation and assurance weldquality between each work post, had improved efficiency of assembling greatly, can satisfy fully and produce and design requirements.
4, assembly quality is better than the making quality of former technology, former operation is to assemble on the high chain-wales of the 1-2 rice of setting up, because place restriction, be difficult for the location in mini three links pipe and the header assembling process, visual appearance is relatively poor, existing operation more can be controlled fitted position well under this advantageous conditions in ground, the assembling moulding is attractive in appearance.
5, former operation welding position is undesirable, forms all position welding, has increased the welding difficulty, difficult quality guarantee, so the welding quality of seam will be under some influence, existing operation is welded in the planimetric position comprehensively.
Description of drawings
Accompanying drawing is the structural representation of vaporization gas hood of the present invention.
Summary of the invention
The method of repairing and assembling of the vaporization gas hood of converter vaporization cooling boiler of the present invention is characterized in that comprising the steps:
1, according to the specification requirement of design or drawing, the straight tube of mini three links Guan Yiduan is not reserved fitting allowance, Directly weld mutually with circular header;
2, with circular header horizontal positioned on the ground, the axis of mini three links pipe is in vertical direction, and is little The straight tube of three-way pipe one end welds mutually with circular header;
3, two of the mini three links pipe other end breeches pipes weld with comb respectively.
In figure, circular header 1 horizontal positioned, the axis of mini three links pipe 2 is in vertical direction, and is little The straight tube 3 of three-way pipe 2 one ends welds mutually with circular header 1, at horizontal level mini three links pipe 2 is welded Be connected on the circular header 1; Two breeches pipes 4 of mini three links pipe 2 other ends weld with comb 5 respectively. By above-mentioned processing method, can easily circular header 1, mini three links pipe 2, comb 5 be connected into one Body.
The present invention with circular header horizontal positioned on the ground, the axis of mini three links pipe 2 is in vertical side To welding mutually with circular header, more can control fitted position well, the assembling moulding is attractive in appearance, is not subjected to operation empty Between the restriction, easier location in mini three links pipe and the header assembling process. After the whole assemblings of riveter are finished, The welder just can carry out the welding of comprehensive plan-position, reduces work holdup situation and assurance between each work post Weldquality has improved efficiency of assembling greatly, can satisfy fully and produce and designing requirement. The present invention falls Low welding difficulty is welded in the plan-position comprehensively, guarantees to a certain extent welding quality.
