Description
Technical field
The utility model relates to a kind of Continuous Casting Rolls with internal cooling structure.
Background technique
Continuous casting is the production technology by high-temperature molten steel direct continuous casting at steel billet, and fan-shaped section Continuous Casting Rolls are by crystallized device
Cooled and solidified is up to 900 at the casting blank bending of lower thickness green shell, aligning, guiding, the equipment of traction, Continuous Casting Rolls and temperature
DEG C~1100 DEG C of slab directly contacts and by slab heat radiation, also aligned by roller self weight, slab weight and casting blank bending
The effect of power, in addition the influence of secondary cooling shower water, iron scale etc., operating condition is very severe, is easy to produce thermal stress fatigue
The disabled status such as crackle, deformation.In the case where stagnant base occurs in continuous casting, fan-shaped section region cooling water majority, which is in, closes shape
State, Continuous Casting Rolls stop operating and with high temperature slab Static Contact, under the action of a large amount of thermic loads, roll body is easily deformed.
The fan-shaped section Continuous Casting Rolls of mainstream steel mill of the country can be divided into the multiple types such as whole roller, metamerism roller and mandrel roller at present.
Whole roller due to roll surface be it is whole be uniformly process, make it have that concentricity is good, and roll surface absolute altitude is consistent, no cooperation
The advantages that gap, assembly work amount is small.Its shortcoming is that used split bearing is expensive, and failure rate is higher, therefore
Whole roller has been rarely employed at present.
Metamerism roller great advantage is that each merogenesis roll body can be independently operated, and is not limited to specific roller, i.e., when in roller
Other merogenesis roll bodies cannot be in use, that remaining root merogenesis roll body still can be applied in other rollers, and reduction is produced into
This.But when the shortcomings that metamerism roller is the ring wear or Rig up error of the water connector sleeve between merogenesis roll body, it will cause cooling water
Leakage, cooling water can enter Bearing inner, cause bearing reduced service life；In addition, cooling water can also be spilt into from bearing block
Roller outer influences slab quality.
Mandrel roller has had been more and more widely used in steel mill at present, as shown in Figure 1, its structure by multiple rollers set 1,
The composition such as mandrel 2, bearing 3, bearing block 4 its main feature is that roller set 1 is mounted on mandrel 2, and takes 5 connection type of key to fix, respectively
Bearing 3 is supported on mandrel 2.A possibility that mandrel roller is connected without water jacket, avoids cooling water leakage, is conducive to stablize life
It produces；And using standard rolling bearing, use cost is lower than whole roller.The shortcomings that mandrel roller, is that mandrel length is longer and covers it with roller
Between installation be not easy, the prolonged online dismounting using rear mandrel needs to carry out using special drawing equipment, and without cooling
Structure is also easy to produce the disabled status such as thermal stress fatigue crackle, deformation.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of Continuous Casting Rolls with internal cooling structure, this continuous castings
The defect that roller overcomes traditional metamerism roller and mandrel roller to apply, solution metamerism roller centre seepy question, and simpler than the assembly of mandrel roller,
Difficulty of processing is low, and cooling effect is more preferable, extends the service life of Continuous Casting Rolls.
In order to solve the above technical problems, it includes several composite rolls that the utility model, which has the Continuous Casting Rolls of internal cooling structure,
Set, two outside mandrels, two intermediate mandrels and bearing block, described two intermediate core between centers are every coaxially arranged and be located at described
Between two outside mandrels, the bearing block is respectively arranged in the outer end and two intermediate mandrels of described two outside mandrels
Portion, the composite roll set include the jacket and inner sleeve of fitting and pass through welded connecting, and the inner sleeve both ends are respectively equipped with into water
Mouth and water outlet, outer surface are equipped with spiral sink, and spiral sink both ends are respectively communicated with the inlet and outlet, described
Intermediate mandrel is equipped with blind-hole type cooling water channel along axis, and the intermediate mandrel both ends are respectively equipped with the inlet opening of connection cooling water channel
With apopore and end face is equipped with keyway, and the outside mandrel is equipped with cooling water hole and is equipped with keyway in inner end, if described
Dry composite roll set be sheathed between the outside mandrel and intermediate mandrel respectively and two intermediate mandrels between and pass through key
It is connected with keyway, the inlet and outlet at composite roll set inner sleeve both ends are respectively communicated with corresponding outside mandrel and intermediate mandrel
Cooling water hole, inlet opening and apopore.
Further, this Continuous Casting Rolls further includes rotary joint, and the rotary joint is set to the outer end of the outside mandrel simultaneously
And the cooling water hole of the connection outside mandrel.
Further, this Continuous Casting Rolls further includes several O-ring seals, and several O-ring seals are set to the outside mandrel
Between intermediate mandrel outer ring and composite roll set inner ring and it is located at the cooling water hole two sides of the outside mandrel, intermediate core
The inlet opening two sides and apopore two sides of axis.
Since there are the utility model the Continuous Casting Rolls of internal cooling structure to use above-mentioned technical proposal, i.e. this Continuous Casting Rolls two
A intermediate core between centers every it is coaxially arranged and be located at two outside mandrels between, bearing block be set to two outside mandrel outer end
With the middle part of two intermediate mandrels, composite roll set includes the jacket and inner sleeve of fitting, inner sleeve both ends be equipped with inlet and outlet,
Outer surface is equipped with the spiral sink of connection inlet and outlet, and intermediate mandrel is equipped with blind-hole type cooling water channel and both ends along axis
Inlet opening and apopore equipped with connection cooling water channel, outside mandrel are equipped with cooling water hole, and composite roll set is sheathed on outside mandrel
It between intermediate mandrel and between two intermediate mandrels and is connected by key, composite roll covers the water inlet at inner sleeve both ends and goes out
The mouth of a river is respectively communicated with cooling water hole, inlet opening and the apopore of corresponding outside mandrel and intermediate mandrel.This Continuous Casting Rolls overcomes tradition
The defect of metamerism roller and the application of mandrel roller solves seepy question among metamerism roller, and assembles simple, difficulty of processing than mandrel roller
It is low, and cooling effect is more preferable, extends the service life of Continuous Casting Rolls.
