Description

Copper making refine grate installation method
Technical field
The present invention relates to a kind of project installation method, especially a kind of Copper making refine grate installation method.
Background technology
Refine grate technology, is specific to copper scap and smelts and the Copper making technology of a kind of advanced person developed, with it The smelting equipment of its similar functions is compared, and refine grate cost is low, applied widely, smelting time is short, energy-conserving and environment-protective, and grate is originally Body is made up of arc-shaped base, side wall, headwall, furnace top cover etc., the most also cradle type supporting arrangement and hydraulic tilting device, but Being that cradle type supporting arrangement the most often goes wrong, its deviation observing and controlling adjusts extremely complex difficulty, does not currently also have one Overlap complete installation procedure and ensure its smooth enforcement, and in work progress, large scale hoisting machinery platform to be used Class, with high costs.
Summary of the invention
Present invention aim to solve existing Copper making refine grate in the problems referred to above present on installation, it is provided that A kind of every deviation is little, and installation accuracy is high, can effectively reduce the Copper making refine grate installation method of installation cost.
The concrete scheme of the present invention is: Copper making refine grate installation method, comprises the steps:
A) on the furnace bottom die-filling frame of bent frame dedicated set, furnace bottom framework is carried out assembly production, complete to get on the right track simultaneously Assembly welding;
B) arranging saddle lower railway and install tracking and command network, this tracking and command network is arranged by the following method: measure the transversal line of two saddles, the longitudinal axis Line, absolute altitude, using the midpoint line of the arc track of two saddles as saddle observing and controlling axis, more respectively from two saddles are respective Point measures to the left, to the right two sections of equal arc length, using the end points of left and right arc length as left point, right point, and between left point, right point Arc length account for the 2/3 of the total arc length of arc track and be advisable, two left points and two right points are collectively forming a rectangle;
C) processing saddle surface of base, parallels seat is starched, levelling;
D) saddle is installed in place: before saddle is in place, first determine on saddle saddle detection and localization line in place,
Test point, then makes saddle base plate center line, makes midpoint at arc track upper surface the most again, as with the body of heater longitudinal axis The installation test point that line aligns, and perform labelling with sample punching, the lifting carrying out saddle the most again is in place;
E) saddle is checked, structure adjusting: 1. saddle install in place after, according in step b arrange tracking and command network, with the most fixed The midpoint of good arc track upper surface, as test point, carries out centering, looks for absolute altitude;2. detect and adjust the absolute altitude of two saddles Difference;3. arc track upper surface is levelling along body of heater y direction;4. with arc track upper surface as test point, check and adjust two saddles The range deviation of seat, the parallel misalignment of two saddles;5. based on the tracking and command network in step b to saddle along body of heater transversal line side Levelling to carrying out;6. the radian of the arc track of two saddles is detected;7. with two left points, the square of two right formation of two saddles Shape is detection faces, and the catercorner length detecting and adjusting this rectangle is poor;8. the distance of repetition measurement two saddle and the depth of parallelism;9. saddle ground Foot bolt fastens, and parallels is fixed, and carried out back-grouting;
F) roller cage, get on the right track installation in place: time in place, roller cage, the midpoint got on the right track all align the midpoint of saddle, just get on the right track After Wei, temporary support is used to be fixed;
G) body of heater tiling arrangement is installed: in installation process, it is to be ensured that two respective upper and lower ear mount pin shaft hole axis of oil cylinder must Must be parallel with body of heater longitudinal axis, two lower ear base pin shaft hole axis are parallel, and two upper ear seat pin shaft hole axis are parallel;
H) furnace bottom framework is installed: to get on the right track as assembling mould bases, be directly installed on by the furnace bottom framework of pre-assembled on getting on the right track, In installation process, between furnace bottom framework and ground, set up temporary support;
I) abutment wall, top cover and wind and smoke interface tube are installed;
J) burner is installed.
In the present invention, the arc track upper surface described in step e is levelling along body of heater y direction, and its leveling method is as follows: Equidistant several points of making in both sides, arc track midpoint, draw vertical with arc track edge straight by these points respectively Line, detects the axial levelness of arc track by horizon rule on these straight lines and is adjusted.
In the present invention, in step e, saddle carries out levelling along body of heater transversal line direction, and its leveling method is as follows: from the arc of saddle The midpoint equal length of shape track measure left point, right point, and meet arc length between left point, right point and account for the 2/3 of arc track overall length, With sample punching perform labelling, with left point, right point line for detection line, detect the levelness of this line, and root with precision level The levelness of saddle is adjusted according to testing result.
Detecting the radian of the arc track of two saddles in the present invention in step e, its method is as follows: make a standard triangle sample Plate carries out radian separate-blas estimation, as excessive in radian deviation, then carried out the arc track on saddle by adjustment base inclined sizing block Adjust.
Installation abutment wall described in step i, top cover and wind and smoke interface tube in the present invention, its installation is divided into three assembly lists Unit, lower wall body is first module, and upper frame is second unit, and airduct, smoke pipe, blower fan and flue gas interface are the 3rd list Unit, each unit assembly erection sequence be from bottom to top, first intermediate and then both sides, and lower wall body needs to arrange interim before welding Support, prevents welding deformation.
The installation of burner in step j in the present invention, the orientation angles of the installation of burner is to be fixed the position of seat by burner Determine, burner fix the installation of seat include burner fix seat Primary Location, burner fix seat be accurately positioned and burner fix seat with Being welded to connect of furnace wall.
It is as follows that heretofore described burner fixes seat accurate positioning method: fix each spot welding of two-port one of seat at burner Angle steel, finds burner fix the center of seat and hole on angle steel, then draws two steel wires, wherein moves the fire designed to for one The optimal shock point of flame, burner fixes seat Flange Plane should be vertical with this root wire;Two burnings designed moved to by another root steel wire Mouth point of symmetry, in said process, burner is fixed seat center, the optimal shock point of flame and two burner point of symmetry and should be maintained at same In vertical plane.
