High speed rotation is asked to still suffer from the slab weight of 1000 DEG C or more high temperature, therefore roll body must make water-cooling structure form.Existing roller
Intracoelomic cavity water route is separated by rotary joint into and out of hot and cold water.Specific constructive form is as shown in Figure 2：Roll body 1, left roller end 2, into
Water pipe, right roller end 4, bearing block 5, rotary joint 6, intake antrum 10, backwater cavity 11.
Water route operating path is as follows：Water inlet pipe is elongated tubular, and normal length is suitable with barrel length (about 2m), diameter very little
(about 40mm or less) right end is inserted into rotary joint 6, and left end is inserted into left 2 endoporus of roller end, when intake antrum 10 is worked with 0.5MPa
When pressure is intake, hot water is gradually risen by roller surfaces heat radiation in backwater cavity 11, and hot water passes through 4 endoporus of right roller end and water inlet
3 outer diameter of pipe flows back in rotary joint 6.
But roller work has the following problems：Roll body 1 is welded on one (for revolving body), water inlet with left and right roller end 2,4
Pipe and rotary joint 6 are fixed；When 1 high speed rotation of roll body, under water inlet pipe water outlet can be in 2 endoporus of left roller end
It hangs down, generates interference therewith；If water inlet pipe is extracted from rotary joint 6, hot water or cold water does not become circuit in roll body, to
The function of losing water cooling roll body quickly, causes water cooling roller channel to damage.

The other end is connected by the second fixing sleeve 8 with right roller end 4；Second water inlet pipe, 7 one end passes through 8 one end of the second fixing sleeve and right roller end
4 are connected, and the other end and rotary joint 6 are closely coupled.As shown in figure 3,3 size of the first water inlet pipe is 34 × 4 × 2400mm of Ф, the
Two water inlet pipes, 7 size is 33 × 4 × 450mm of Ф, and the first fixing sleeve 9,8 size of the second fixing sleeve are 50 × 7.5 × 70mm of Ф,
These four original paper materials are mild steel Q345-A, and solderability is good.
Suitable gap is extremely important between second water inlet pipe 7 and the second fixing sleeve 8, if gap is excessive, can cause into
Water inlet in water cavity 10 reflux from gap goes out, and influences the cooling effect of roll body 1, if gap is too small, when roller runs one section
Between after, can incrustation scale is left at this, gap is blocked, the second water inlet pipe 7 and roll body 1 is made to rotate together, so as to cause second into
Water pipe 7 is extracted from rotary joint 6, loses the effect of cooling roll body.
Roller structure before transformation is as shown in Fig. 2, roll body 1 is welded on one with left roller end 2, right roller end 4, for revolving body；Into
Water pipe and rotary joint 6 are fixed；When 1 high speed rotation of roll body, under water inlet pipe water outlet can be in 2 endoporus of left roller end
It hangs down, generates interference therewith；If water inlet pipe is extracted from rotary joint 6, hot water or cold water does not become circuit in roll body, to
The function of losing water cooling roll body quickly, causes water cooling roller channel to damage.
The schematic enlarged-scale view of first fixing sleeve 9 and the second fixing sleeve 8 as shown in figure 3, the second water inlet pipe 7 outer diameter ratio first
Small 0.5~the 1mm of 3 outer diameter of water inlet pipe ensures that gap is 0.5~1mm between the second water inlet pipe 7 and 8 radial direction of the second fixing sleeve.
Roller service life is 3~4 months before transformation, every 40,000 yuan or so of roller manufacturing cost, if water route is asked
Entire roller is removed or is rectified and improved at least spending 20,000 yuan or more by topic.After transformation, the service life of every roller extends to 2.5 years
More than, general hot rolling line at least uses 40 water cooled rollers, can at least save 1,200,000 yuan of cost of equipment every year.
Embodiment 2
Roller structure after transformation as shown in Figure 1,3 one end of the first water inlet pipe is connected by the first fixing sleeve 9 with left roller end 2,
The other end is connected by the second fixing sleeve 8 with right roller end 4；Second water inlet pipe, 7 one end passes through 8 one end of the second fixing sleeve and right roller end
4 are connected, and the other end and rotary joint 6 are closely coupled.As shown in figure 3,3 size of the first water inlet pipe is 34 × 4 × 2400mm of Ф, the
Two water inlet pipes, 7 size is 32 × 4 × 450mm of Ф, and the first fixing sleeve 9,8 size of the second fixing sleeve are 50 × 7.5 × 70mm of Ф.
Embodiment 3
Metallurgical hot rolling slab water cooled rolls includes above-mentioned roller-way, is connected to the roll shaft at roller-way both ends, and roll shaft is inserted into roller-way end,
It is formed and is fixedly connected with merging, axially extending bore is equipped in roller-way, is respectively equipped with and axially extending bore phase in roller-way in the roll shaft at both ends
The inlet and outlet of unicom.
Embodiment 4
This roller-way restoration and reuse is on hot rolling line strip edge heater rollgang, 1100 DEG C of board briquette, roller-way
The speed of service is 0~20m/s, and water cooling roller channel uses certain company's roller.
Roller-way adaptation step is as follows：
3 one end of (1) first water inlet pipe welds together with the first fixing sleeve 9, and the other end and the second fixing sleeve 8 are welded on one
It rises；
(2) the first water inlet pipe 3 and the first fixing sleeve 9 after being fixedly connected are fixed on the inside of left roller end 2；
(3) the second fixing sleeve 8 after being fixedly connected is fixed on the inside of right roller end 4；
(4) it carries out the roll body after above-mentioned steps and carries out static balancing test；
7 one end of (5) second water inlet pipe is injected in rotary joint 6, and the other end injects in the second fixing sleeve 8, and is consolidated with second
Surely cover between 8 radial directions that there are the gaps 0.5mm.
For the revolving member (such as roller gear, uniform disc) of certain symmetrical geometries, because of foozle, material
Inertia force caused by unequal reason is uneven, is that can not determine the size and orientation of balance quality by calculating.Even if
Certain components have apparent several pieces of eccentric mass, it is also possible to size and its barycenter position of each eccentric mass can not accurately be determined
It sets.Therefore case above can only all determine the size and orientation of balance quality by static balancing test.
The basic principle of static balance experiment is to be based on such a universal phenomenon, effect of any object in terrestrial gravitation
Under, center (namely barycenter) is always at extreme lower position.Since revolving member barycenter deviates shaft, component cannot be made arbitrary
Position remains stationary is motionless (i.e. static balance), and this phenomenon is known as static unbalance.Add on balance quality entity is exactly adjustment revolution
The centroid position of component, is located in shaft.
Equipment used in static balancing test is known as static balancing frame, and major part is mounted in two in same level
Edge-shaped guide rail parallel to each other.
The axle journal of roll body in above-mentioned steps (3) is supported on two guide rails when static balancing test.If roll body is static unbalance
, then under the action of eccentric neutral, it will be rolled on the edge of a knife.After it determined offset direction of the roll body barycenter with respect to shaft,
Appropriate location (right over i.e.) in the opposite direction takes suitable clay temporarily to be pasted on roll body instead of balance quality, repeats
The above process.Through repeatedly adjusting the size or radial position repetition test of clay, until roll body all remains stationary at an arbitrary position
It is motionless, the mass-radius product W of institute's viscose glue mud at this timeb.Finally according to the concrete structure of roll body, by WbThe balance quality that determines of size it is solid
Surely the corresponding position of roll body is arrived, roll body can be made to reach static balance.
WbBalance quality is determined by following formula；
Wb=Mbrb
MbAnd rbRespectively increased balance quality and its barycenter to diameter.
