Description
Technical field
The present invention relates to steel band production equipment technology, more particularly, to a kind of backing support roller and applies the back of the body
Serve as a contrast the milling train of support roller.
Background technology
Milling train is a kind of equipment that thick steel band is rolled into thin steel strip using working roll, is produced and processed for steel band.Typically
Milling train in rolled steel strip, working roll will bear the pressure of very big intensity, and working roll is axially generally long, in order to
Prevent working roll from bending deformation, one group of (several) support roller can be set in the dorsal part of working roll, near the support roller of working roll
Referred to as backing support roller.
In mill milling steel band, working roll pressed-steel band can produce substantial amounts of heat, in order to prevent from burning out working roll or
Steel band is burnt out, needs constantly to cool down working roll when milling train works.Wherein, a kind of common type of cooling is to steel
Band, which bites mouth, to be continued to spray cooling oil, but this mode cooling oil is sprayed on steel band from outside and bitten on mouth, due to working roll and steel
Interband pressure it is very close, the steel band from outside bites mouth and flowed away and drops most cooling oil soon, only sub-fraction
Cooling oil can be brought into inner side, and therefore, existing this type of cooling cooling effect is simultaneously bad, and to the amount requirement of cooling oil
It is very big, cause to waste.
The content of the invention
The invention aims to solve the problems of the prior art, a kind of backing support roller and its milling train are proposed, should
Backing support roller is applied on milling train, changes the type of cooling to working roll, and its cooling effect is more preferable, and can save cooling
The dosage of oil.
The technical solution adopted by the present invention is as follows：
A kind of backing support roller, for supporting the working roll of strip mill, the backing support roller includes support base, mandrel
And bearing, the support base both ends are provided with mounting hole, the mandrel both ends are fixed in the mounting hole, and the bearing is provided with more
Individual uniform intervals are arranged on the mandrel, and the support base corresponds to and groove is provided with the bearing, and the groove is used for direction
The bearing of the support base side is embedded in the groove, and atomizer is provided with the interval of the bearing and bearing.
Further, the mandrel is axially arranged with oil-through hole, and the atomizer passes out of described mandrel, and the spray
Oil nozzle connects the oil-through hole.
Further, the mandrel corresponds to the first oil outlet that the oil-through hole is communicated with the bearing, the axle
The second oil outlet that inner side is communicated with Bearing inner is held, second oil outlet connects with first oil outlet.
Further, the 3rd oil outlet of Bearing inner is communicated with the outside of the bearing.
Further, the support base dorsal part is provided with bayonet socket, to the branch when bayonet socket is used to install the support base
Support seat positioning.
Further, one of axial side wall of the bayonet socket concaves setting.
A kind of milling train, the milling train include working roll and backing support roller, the working roll and the backing support roll shaft
To be arrangeding in parallel, and the surface of the working roll is resisted against the bearing surface of the backing support roller, and the backing support roller is
Backing support roller as described above.
The beneficial effects of the invention are as follows：
The backing support roller of the present invention, for supporting the working roll of strip mill, it is at the interval of the bearing and bearing
Place is provided with atomizer, and during work, cooling oil is sprayed onto the upside of working roll by atomizer, and cooling oil flows down along working roll both sides, divides
It does not flow to the inner side and outer side that working roll steel band bites mouth equably, therefore there is more preferable cooling effect；Due to cooling effect
Raising, can artificially design and spray less cooling oil, therefore can also save the dosage of cooling oil.
The preferred embodiments of the invention and its advantage, embodiment will be combined and be further described.
