Description
Technical field
The present invention relates to a kind of converting furnace installation method, specifically, be that a kind of installation accuracy that improves is made with shortening construction
The flash converting furnace installation method of the improvement in industry cycle.
Background technology
Blowing operation be indispensable operation in copper smelting by pyrometallurgy operation, air is blasted copper matte regulus melt and with copper matte regulus melt
In ferrum, sulfur carry out oxidation reaction and release heat, maintain self-heating blowing, operate through slag-formation period and copper making period, generate blister copper.Mesh
Before, along with the fast development of national economy, process of industrialization is substantially accelerated, especially heavy duty industrial project institute in nation-building
Accounting weight strengthens year by year.At numerous areas such as heavy duty industrial projects, according to production technology needs, steel framework beam is popularized in a large number
Design and use, the coloured industry such as melting main building especially for some special industry technological requirements is accomplished by using this
Plant version.
400,000 tons/year of smelting process project melting main building flash converting furnace masters of Jinchuan, Guangxi non-ferrous metal company limited
Will by basis, bottom girder, furnace bottom cooling system, reaction tower, sedimentation tank, uptake flue, the shockproof support of sedimentation tank, furnace roof adnexa,
The part composition such as support frame frame, flue valve support, platform, outer beam bracket, the installation of converting furnace water jacket, layout of spring, this engineering sets
Meter slag line overall length is 21800mm, and slag line width is 6700mm, pool depth 900mm, furnace height 2100mm, body of heater gross weight
1200.241 tons, wherein furnace equipment total amount 803.86 tons, Copper Water Jacket 396.382 tons.Flash converting furnace is installed all to use and is set up
Scaffold coordinates Factory Building maintenance driving or setting up scaffold coordinates autocrane or crawler crane two ways, front
A kind of method is with sedimentation tank along body of heater surrounding, sets up all round victory scaffold and set up multilamellar peace centered by reaction tower, uptake flue
Dress job platform；Integral falsework system is reserved component converse transportation and is entered body of heater passage；The all components of body of heater are unloaded, and have bad luck, just install
Position is main uses maintenance driving in plant floor；Later approach is
All round victory scaffold establishment multilamellar mounting operation platform is set up at center；Integral falsework system reserve component converse transportation enter body of heater lead to
Road；The all components of body of heater are unloaded, and have bad luck, install main utilization in place and be arranged in autocrane or the crawler belt of body of heater both sides
Formula crane.
The shortcoming of known above two method: first method needs segmented-erection all round victory scaffold arranging multiplayer
Operating platform, the needs of setting up of scaffold strictly and accurately check, and preparation is complicated, scaffold is set up requirement partially
Height, because of body of heater height universal 20～about 24m, so needing a point multilamellar to set up, all arranges springboard and protection network at every layer of platform,
And it is limited to body of heater installation procedure and component converse transportation pass effect, first sedimentation tank construction, then reaction tower and uptake flue
Construction；The use of Factory Building maintenance driving, therefore in scheme Factory Building, maintenance driving is that all components of body of heater are unloaded, and has bad luck, just installs
The main tool of position, so the use of maintenance driving reserved lifting from furnace bottom to furnace bottom when needing mill construction to construct in Factory Building
Space, multilamellar platform in lifting space (as a example by this engineering, need reserved 11.76m platform, 17m platform, 23m platform,
28.4m platform, 22～23 line multi-axial cord spacing) column braces beam and plateform system cannot construct that to be necessary for body of heater construction institute pre-
Stay, bring the added burden on installation procedure and potential safety hazard, later stage Factory Building intercolumniation beam so to the integral installation of mill construction
And each layer plateform system construct the difficult problem bringing many such as mill construction parts to have bad luck and install；Extensive operation break-down (first precipitates
Behind pond, reaction tower and uptake flue are installed) scaffold set up that there is also takes up room too big (affect body of heater region Factory Building to tie
Structure is constructed), scaffold usage quantity is too much, and multi-platform layout, the use of many springboards and protection network exists substantial amounts of safety in production
Hidden danger, brings extra management cost to field engineering management.
Second method is to arrange two automobiles in body of heater sedimentation tank both sides (slag tap side and flue outlet waste heat boiler side)
Formula crane early stage arranges a lifting sedimentation tank, and the later stage arranges that two points of uptake flues and reaction tower independently lift, the program
Also needing operation break-down to set up extensive all round victory scaffold, it is empty that the use of autocrane needs to take body of heater surrounding structure platform
Between, a large amount of platforms and the mill construction construction keeping for the later stage of column braces girder and sealing power house bring extra being constructed into
Originally with management cost, a large amount of mechanical one-shifts of another autocrane use increases substantial amounts of mechanical one-shift to integrated engineering construction
Expense.
The most known converting furnace installation method also exists above-mentioned all inconvenience and problem.
