Description
Technical field
The present invention relates to heating furnace manufacturing technology field, the modular manufacturing method and use of specifically a kind of heating furnace
The heating furnace of the method manufacture.
Background technology
Modernization some large scale equipments parameter it is high, part is more, volume is big, weight is big, it is impossible to manufactory manufacture after
Transport device to live, and the shortcomings of having long in time limit, equipment quality hardly possible is controlled of constructing at the scene；With module supply business
Specialized and traffic condition improve constantly, domestic major petrochemical projects are all carrying out different degrees of modularization, with true
Guarantee the quality and the cycle, compared with making in site, modularization has following advantage：
1）More preferable working environment
The condition of work of factory floor manufacture is far superior to field condition, smaller by weather, such environmental effects, and not by existing
Build when solid space limitation, can multimode simultaneously manufactured, there is no work high above the ground after modularization, operating efficiency is significantly
Improve, total lever factor can shorten 4-5 month.
2）More superior manufacturing equipment
In specialized workshop manufacturing process, more superior frock equipment can be used, be conducive to improving operating efficiency and system
(making such as to large-scale steel structure introduces CO to make precision2The high-efficiency welding method such as gas shielded arc welding and submerged-arc welding, use special machine
Device is cut and is eliminated rust, and there are sandblasting paint shop, large-scale heat treatment, exposure room and the professional blanking equipment of specialty in factory)；
Workshop manufactures, and has special manufacture of steel structure platform, and weldquality is easy to control, and flatness, linearity is conveniently adjusted.
The sandblasting paint shop of specialty, thoroughly, roughness is up to standard for sandblasting, and paint is uniform, attractive in appearance, and is lost small.
One of key of heating furnace manufacture is exactly to weld, and the welding of pressure parts and steel construction is most important, indoor welding
Following advantage is welded with compared to in-site installation open air：
1. environment temperature can be controlled effectively, reach the temperature required by welding；
2. wind speed can be controlled effectively, it may be necessary to set draught exclusion device, relatively outdoor more simple；
3. welding is protected from weather influences, it may be necessary to take measures to make humidity during welding to reach standard requirement；
4. welder is under conditions of welding surroundings are excellent, and beneficial to playing the due technical ability of welder, and labour intensity is than big out of doors
Amplitude reduction, raises labour productivity, it is ensured that product quality；
5. indoor welding can also preferably set safety prevention measure, it is ensured that safety in production.
3）Job engineering efficiency higher
Module supply business has special organization and professional contingent, and orderly the carrying out of energy efficiently produces.With site operation phase
Than, it is not necessary to total bag and owner to live various places, road, the management such as the coordination of hydroelectric facility etc. and HSE.
4）Committed step better quality controls (lining, welding of tubes)
Workshop manufacture (can such as change operation difficulty high for the welding of the important components such as boiler tube is createed than live more favorable condition
Vertical position welding and fixed weldering is for the low downhand welding of operation difficulty and rotates weldering, conveniently take interior argon filling, preheating and heat treatment measure etc.),
Be conducive to improving welding quality, reduce reclamation work amount；
Workshop manufacture can reduce that lining construction is outdoor and work high above the ground difficulty, can be put down using the irrealizable castable of making in site
Lining, improves lining quality.
5）It is easy to quality control
In addition to the manufacturing equipment and inspection equipment that have specialty, manufactory has also carried out pre-assembled, can not only check final size,
(such as whether rationally design of node, node diagram is either with or without statement to also help discovery design document imperfection or unaccommodated details
With the presence or absence of situation about being difficult to carry out etc. in clear, manufacture), scattered material to asking that Assembling just finds is evaded to greatest extent
Topic, is corrected in time.
6）Work on the spot amount is reduced, and is easy to control the construction period
Modular manufacturing not by the wind, the influence of the outside environmental elements such as rain, snow, typhoon, the manufacturing cycle is short.Modularization greatly reduces existing
Field installation period, the scene only once jacking work in place of integral module main equipment.For scene changing without construction site
Expansion project, construction period short grassroot project, and can short construction period Petrochemical Enterprises (north frost place), modularization
It is first-selected.
7）Expense is relatively reduced
Expense aspect qualitative analysis：It is assumed that workman is identical with manager-related factors, expense aspect qualitative analysis is carried out.
Installation fee：The prefabricated expense of factory modularization has very big reduction relative to in-site installation expense：
1. the site operation ratio cost of labor that is prefabricated in the factory is high；
2. prefabrication efficiency is improved, can effective reduces cost；
3. prefabrication, Assembling can save live place and take and space expenses, rule of thumb 100,000,000 yuan of contract output values, greatly
Generally need 10,000 square metres of in-situ precast places；The temporary facility expense such as storehouse, office can be saved simultaneously；
Prefabrication, Assembling workmen is reduced, and the in-site installation cycle greatly reduces, and the management of owner can be greatly reduced
Personnel and administration fee.
The content of the invention
The technical problems to be solved by the invention are directed to the present situation of prior art, there is provided can shorten the manufacturing cycle, subtract
