Sidepiece is provided with the second fixed via, and first fixed via and first fixed via are provided with bolt.
Further：First side plate and second side plate are parallel to each other.
Compared with prior art, this utility model technique effect includes：
1st, of the present utility model simple and reliable for structure, easily operated, and can guarantee that the reparation of roll and the production of annealing furnace
Efficiency；It is easy to operate in hoisting process, achieves safety in production.
2nd, for heap postwelding roll heat treatment, using this utility model after, the roll neck hardness after annealing is improved on year-on-year basis
20%-30%, meets onsite application expection；After heap postwelding is improved, the hardness of roller neck is improved to HB265 by HB165, more preferably
Meet use requirement, and reflect during tracking good.
3rd, transformation budget rationally, reduces production cost, and can have obvious benefit.
(1) roller neck hardness be cause roll tile kilning and roll wear after bring roll input amount increase main cause
One of, through to company over 4 years new roll input amount count, every year on average roll put into 0.71 yuan/ton, after transformation minimizing
0.12 yuan/ton of input, by 800,000 tons of calculating of annual production.9.6 ten thousand yuan of annual saving expense.
(2) due to the accident roll changing time that causes after roller neck abrasion and change between watt-hour to estimate, 20 will be saved every year
Hour, roll 80 tons of output of steel, 200 yuan of calculating of steel profit per ton on an hourly basis.More than 30 ten thousand yuan of the estimated creation of value.
(3) a watt accident is ground due to what roll neck abrasion caused, need to change watt, according to 850 roll gluing wood spools watt in recent years
Usage amount, estimates with 8% as roll neck particle tile kilning by about 350 pieces every year on average.1.12 ten thousand yuan of estimated saving.

Specific embodiment
In order that those skilled in the art more fully understand the technical solution of the utility model, with reference to of the present utility model
Accompanying drawing, carries out clear, complete description to the technical solution of the utility model, based on the application in embodiment, this area is general
Other similar embodiments that logical technical staff is obtained on the premise of creative work is not made, should all belong to the application
The scope of protection.
According to technical requirements, in the case where existing annealing furnace is basically unchanged, annealing furnace surrounding does not allow to have which
Big change, produce can be heat-insulated device roll neck ring is wrapped, and roll body can be held up, enable roll equal
Even be heated, roll neck temperature change should be within 100 DEG C.To can bear the weight of roll at high temperature and can not become
Shape, and the device must have enough stability, safety in use.
As shown in figure 1, being the structure chart of surfacing roll roll neck attemperator in this utility model；
The structure of surfacing roll roll neck attemperator includes：Base plate 1, the first side plate 2, the second side plate 3；First side plate 2,
The bottom of two side plates 3 is vertically welded in the top of base plate 1, and the top surface of the first side plate 2 is provided with the first cambered surface supporting mouth 21, and second
The top surface of side plate 3 is provided with the second cambered surface supporting mouth 31, forms draw-in groove 4 between the first side plate 2, the second side plate 3.Draw-in groove 4 is arranged
The periphery for having heat-barrier material, surfacing roll roll neck attemperator is also coated with heat-barrier material.
First side plate 2, the second side plate 3 are parallel to each other.First side plate 2, the second side plate 3 are respectively arranged with the first fixed via
6.
The electrode band steel of first side plate 2, the second side plate 3 from height 65mm* length 230mm, according to annealing furnace inner wall size
And the profile of roll itself, weight etc. determine bracing frame profile size.According to the character of existing roll overlaying annealing furnace, structure is special
Point and environmental requirement, can only be transformed on existing annealing furnace.Two sets of surfacing roll roll neck attemperators can be surrounded up and down
Roll, the first cambered surface supporting mouth 21, the second cambered surface supporting mouth 31 can encircle the roll neck of roll.
Asbestic blanket selected by heat-barrier material, it would be desirable to which the roller neck of annealing is placed in the first cambered surface supporting mouth 21, the second cambered surface
In supporting mouth 31, top compresses surfacing roll roll neck attemperator, upper and lower two pairs the first cambered surface supporting mouths 21, the second cambered surfaces
The tight encirclement of support mouth 31 simultaneously supports roll neck, until holding stage, guarantor of the roller neck in asbestic blanket after annealing furnace temperature is raised
The lower temperature of shield rises High variation less, plays heat-blocking action.
Table 1：Hardness balance using roll neck before and after this utility model
From data above, using this utility model after, Brinell hardness averagely improves more than 100, roller of annealing
The hardness of neck has reached the requirement of work roll cooling.After tracking at the scene, field technician's reflection roll neck is than before in abrasion journey
Take a turn for the better on degree.
As shown in Fig. 2 being the front view for being incubated rockwool blocks 5 in this utility model.
In hoisting process, the asbestic blanket of top surfacing roll roll neck attemperator because not being completely fixed, often from
Drop out.Replace asbestic blanket with insulation rockwool blocks 5, insulation rockwool blocks 5 are fixed in draw-in groove 4.
The shape of insulation rockwool blocks 5 is adapted with the shape of draw-in groove 4, top surface is provided with cambered surface opening 51, sets in sidepiece
It is equipped with the second fixed via 51.Insulation rockwool blocks 5 are put in draw-in groove 4, bolt is fixed logical through the first fixed via 6, second
Hole 51, insulation rockwool blocks 5 are fixed on the first side plate 2, the second side plate 3.
Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment is only wrapped
Contain an independent technical scheme, this narrating mode of description is only that those skilled in the art should for clarity
Using description as an entirety, the technical scheme in each embodiment can also form those skilled in the art through appropriately combined
