Abstract
The utility model provides a rough rolling edger roll breakwater device grinds into the plane according to 90 back of clockwise rotation in the position of the edger roll bearing box reference column perpendicular to edger roll surface of cylinder, installs the breakwater that is equipped with the bar bolt hole on the grinding plane of edger roll bearing box reference column to paste the breakwater inclined plane and lean on the edger roll surface, the breakwater side covers has the clamp plate, fixes clamp plate and breakwater on the grinding plane of edger roll bearing box reference column through the countersunk head bolt. The utility model discloses can improve edger roll surface wear uniformity, promote the smooth finish of roll surface, prolong the life cycle of edger roll, reduce edger roll grinding number of times, the reduction of slab limit portion temperature drop simultaneously, the limit portion quality improvement of belted steel.
Description
Technical field
The utility model belongs to mechanical equipment of steel rolling field more particularly to a kind of hot rolling roughing vertical roll water baffle plate device.
Background technique
It is typically provided with vertical miller in hot rolling line, main function is the finished width for controlling strip, due to vertical
Roller mill is attached on flat roll mill, is before flat roll mill, so compact equipment installation, space according to putting in order
It is narrow.General vertical miller is all without edger roll body of roll water fender, in production due to the forward direction of edger roll, reverse rotation, slab
Edge is constantly washed away by edger roll body of roll cooling water, causes that slab edge cooling velocity is fast, temperature drop is big, and strip is easily caused after rolling
While splitting, the mass defects such as sideline, edge are coarse, quality objection rate is higher, usually presses downgrade processing, larger to the loss of enterprise.
Summary of the invention
The utility model, which is intended to provide one kind, can be improved water blocking effect, reduce slab edge fault rate, extends edger roll and uses
The roughing vertical roll water baffle plate device in service life.
For this purpose, the technical solution that the utility model is taken are as follows:
A kind of roughing vertical roll water baffle plate device, which is characterized in that including vertical roll bearing box positioning column, water fender, pressing plate and
Dormant bolt;Cylindrical body vertical roll bearing box positioning column perpendicular to edger roll roll surface position according to being ground after rotating clockwise 90 °
It is whittled into plane, and vertical roll bearing box positioning column grinding plane and vertical rolls body are on the same line, grinding plane length is greater than vertical
Roller 50~80mm of barrel length is ground in plane and is machined with dormant bolt hole;The water fender for being equipped with bar shaped bolt hole is mounted on
In the grinding plane of vertical roll bearing box positioning column, and water fender inclined-plane is sticked on edger roll roll surface, water fender side is covered with pressure
Pressing plate and water fender are fixed in the grinding plane of vertical roll bearing box positioning column by plate by dormant bolt.
The utility model has the following beneficial effects:
1, edger roll roll surface wearing uniformity greatly improves, and roll surface finish has biggish promotion, extend edger roll
The machine time effectively raises the quality of edges of strip;
2, slab edge temperature drop drops to 20~30 DEG C by original centre and 60~70 DEG C of the edge temperature difference, and reduction amplitude reaches
60% or more, edge fault rate drops to 0.63% by 1.48%, decreases by 0.85%, effectively reduces the operation of subsequent handling
Amount;
3, the service life of edger roll is extended to 2 months by original replacement in 1 month and is replaced, and improves 2 times using the time in machine,
The grinding times for greatly reducing roll improve edger roll utilization rate.
Detailed description of the invention
Fig. 1 is roughing vertical roll water baffle plate device schematic diagram.
In figure: edger roll 1, vertical roll bearing box 2, vertical roll bearing box positioning column 3, pressing plate 4, water fender 5, dormant bolt 6.
Specific embodiment
As seen from Figure 1, it is respectively equipped with vertical roll bearing box 2 in the upper and lower ends of edger roll 1, vertical roll bearing box 2 passes through cylindrical body
Vertical roll bearing box positioning column 3 positioned.The utility model roughing vertical roll water baffle plate device, including vertical roll bearing box positioning column
3, pressing plate 4, water fender 5 and dormant bolt 6;It is pressed in the vertical roll bearing box positioning column 3 of cylindrical body perpendicular to the position of 1 roll surface of edger roll
According to grinding 10mm after rotating clockwise 90 ° at plane, and vertical roll bearing box positioning column 3 is ground plane with 1 body of roll of edger roll same
On straight line, grinding plane length is greater than 1 barrel length 65mm of edger roll, is ground in plane and is machined with 4 dormant bolt holes;It will be equipped with
The water fender 5 of bar shaped bolt hole is mounted in the grinding plane of vertical roll bearing box positioning column 3, and the inclined-plane of water fender 5 is reclined
On the roll surface of edger roll 1,5 side of water fender is covered with pressing plate 4, and pressing plate 4 and water fender 5 are fixed on edger roll by dormant bolt 6
In the grinding plane of bearing housing positioning column 3.
