Description
Technical field
The present invention relates to a kind of replacing options of cold-rolling equipment, specifically the replacement side of cold rolled continuous annealing stove furnace roller
Method.
Background technology
When current cold rolling mill continuous annealing furnace is replaced, when drawing horse dismounting bearing using tradition, shaft strength may be made
It is uneven, cause bearing that can not extract, during furnace roller is removed in the past, we are usually by two before hanging out and installing furnace roller
4 jackscrews of side jack up simultaneously, find that driving side jackscrew is always easily by furnace roller after installation is complete in furnace roller in multiple construction
It fills curved so that jackscrew can not take out, causes us that must not be cut off less than curved part will be hit in stove, this not only increases labour
Amount and significant delays duration.
Invention content
The defects of the present invention is directed to overcome the prior art, provides a kind of replacing options of cold rolled continuous annealing stove furnace roller, carries
High working efficiency and the time for greatly reducing processing fracture of wire, save manpower.
In order to solve the above-mentioned technical problem, the invention is realized in this way：
A kind of replacing options of cold rolled continuous annealing stove furnace roller, it is characterised in that：Include the following steps：

Step 2：Remove bearing and bearing enclosure, axle sleeve of the axis with locking cap fore side and driving side；First by both sides jackscrew
Jack up, bearing is removed using extracting tool, as the gap of bearing and bearing block not enough driving side using jack will integrally to
Fore side moves suitable distance, first both sides jackscrew comes loose when if desired moving integrally in order to avoid jackscrew stress deformation is difficult to take out,
The axle sleeve removed and lock nut are cleaned up, replace axle sleeve inner seal ring；
Step 3：Side shaft holder is operated to remove；Bearing block puts bottom gasket in order when removing；
Step 4：Old furnace roller is removed；Old furnace roller is removed using suspender, counterweight is adjusted according to the mark marked on suspender；It tears open
Except the DATA REASONING of the preceding spacing by between front and rear roller comes out, and make a record；The degree of balance is adjusted using suspender；Furnace roller is removed
Driving side jackscrew is returned with during installation；
Step 5：Furnace roller is installed to stove；
1. first new flange gasket is fixed on furnace wall, and lengthening section is uniformly screwed into driving side spindle nose by fluid sealant smearing,
Then axle supports are removed；
2. trolley is driven forward, in roller push-in stove；It is adjusted forward, backward, to the left or to the right with overhead traveling crane movable hanger
Whole roller axle center, makes it not encounter the edge in hole；One staff provides necessary instruction in driving side with intercom；
3. roller is pushed into until roll shaft；
4. be pushed further into roller reaches final position until the shaft shoulder stretches out bearing 1-3cm；
5. installation band covers bearing and with nut check on axis；
6. with the help of extracting tool and axis lengthening section, adjustment axle center enables in bearing advance seat；Installation operation side roller
The roller support on extracting tool is removed in support；
7. moving trolley is to track-frame balance mark point；
8. being hung with day handlebar extracting tool to level ground, restore local area railing；
Furnace roller is fastened after being installed in place in four direction with bolt respectively；
Step 6：Return dress bearing block and telescopic joint, axle sleeve, bearing block sealing, bearing, lock nut；Bearing seal makes before returning dress
Gap of the roll shaft in bearing saddle bore is identical, and adjustment driving side shaft end is equal with before dismounting to the distance between speed reducer catcher；
Bearing heating temperature must not exceed 120 DEG C when returning dress, and each portion's part is installed in place, and bearing block installs the gasket at four angles when returning dress
And by bolt fastening in place；
Step 7：Furnace roller installation accuracy adjusts
The measurement of bearing concentricity is carried out to fore side and records data；Under the premise of ensureing that fore side height is immovable
Radial missing ± the 0.15mm made both vertically as well as horizontally is adjusted to bearing block, record data after the completion of adjustment；
Use the levelness of frame level measuring roller；During measurement ensure measurement point position in roller center roll surface without
Foreign matter repeatedly measures and ensures that reading is correct and records data；
Adjustment is measured to the concentricity of inboard bearing with reference to the data that horizontal measurement provides, by adjusting driving
The height of side shaft holder looks for the horizontal departure of roller, levelness is measured again after the completion of adjustment, expires horizontal departure
Sufficient 0.05mm/m, then operation side shaft holder is carried out to beat meter reading and appropriate adjustment；
Use the verticality of swing rod measuring roller；Drawing hangs up properly cloth and is conducive to observation to whether there is bar contact same when setting steel wire
When prevent pedestrian from scraping, swing rod measured deviation must satisfy ＜ 0.05mm/m.
The replacing options of the cold rolled continuous annealing stove furnace roller, it is characterised in that：Extracting tool described in step 2,
The extracting tool includes top plate, two screw rods and two semicircle fixtures, and two screw rod upper ends are connect respectively with top plate, two screw rods
Lower end connects two semicircle fixtures, and two semicircle fixtures are buckled in the gap of bearing and bearing block by when dismounting, two semicircles point
It is connected with after not being buckled on the inside of bearing.
The replacing options of the cold rolled continuous annealing stove furnace roller, it is characterised in that：Old furnace roller described in step 4 is torn open
Except in the process, it is ensured that the verticality and levelness of overhead traveling crane opposed rollers.
The beneficial effects of the invention are as follows：Replacement and the efficiency of assembling of cold-rolling continuous annealing unit furnace roller are improved, is reduced because of dress
The reason of method of completing the square, causes the probability that mounted spare is damaged and scrapped, and saves spare parts cost, reduces labor intensity.
