Abstract
A rough-rolling vertical roll hole pattern capable of changing outline belongs to the technical field of steel rolling equipment, and aims at prolonging the service life of a vertical roll, reduce rolling consumption and improve machine output and band steel width accuracy. The technical scheme is that the side wall of the hole pattern is divided into two portions, an included angle formed by the upper portion side wall and the axis line of the hole pattern is larger than that formed by the lower portion side wall and the axis line of the hole pattern, the height of the upper portion side wall is 25 to 65 millimeters in the hole patter axis line direction, the height of the lower portion side wall is 25 to 65 millimeters in the hole pattern axis line direction, and the opening degree of the hole pattern is 235 to 240 millimeters. The rough-rolling vertical roll hole pattern adopts a double side wall hole pattern capable of changing the outline, and appropriately reduces the depth of the hole pattern. In use, the rough-rolling vertical roll hole pattern can change side walls and opening degrees to further guarantee stability of running of rolled pieces, benefit biting of the rolled pieces, reduce accidents of steel stacking and steel blocking, improve plate bandwidth control accuracy, and increase turning times of a vertical roll. Stress concentration areas are avoided by enlarging a fillet of the tank bottom, thereby greatly reducing consumption of the vertical roll.
Description
Technical field
The utility model relates to a kind of roughing edger roll pass, belongs to the steel rolling equipment technical field.
Background technology
Fierce day by day and raw-material rise in price along with the steel industry competition, low-cost production has risen to a new height, at mill, roller consumption proportion in production cost is bigger, high-quality panel production line particularly, the intensity of breaker roll, hardness, roll shape etc. are had relatively high expectations, so the roll expense is also higher.
Traditional roughing edger roll pass is shallow and be one-sided cinclides type because of its groove, sidewall of pass gradient is bigger, in use, along with rolled piece attenuation gradually, the stepped from bottom to top distribution of the wearing and tearing of pass bottom land, bottom land and lower wall contact position are because of painstaking big and maximum with the steel band frequency of exposure in producing, its wearing and tearing are the most serious, this just causes in the turning process of maintenance roll, for guaranteeing pass type shape, must be that benchmark carries out the turning location with the most serious zone of pass wearing and tearing, to satisfy its availability, cause each turning amount quite big, reach each turning amount 5-8mm, proportion is big in the total consumption of roll.In order to reduce the wearing and tearing of roughing edger roll pass, the each turning amount when reducing maintenance increases the turning number of times, prolongs the service time of roll, reduces the consumption of roll, is necessary roughing edger roll pass is improved.
The utility model content
Technical problem to be solved in the utility model just provides that a cover can prolong edger roll service time, improves edger roll pass turning number of times, reduces roll consumption, output and improve the variable outline roughing edger roll pass of strip width precision when improving machine.
The technical scheme that solves the problems of the technologies described above is:
A kind of variable outline roughing edger roll pass, its sidewall of pass is divided into two parts up and down, the angle of upper portion side wall and pass axis is greater than the angle of lower sides and pass axis, upper portion side wall is 25-65mm at the height of pass axis direction, lower sides is 25-65mm at the height of pass axis direction, and the opening degree of pass is 235-240mm.
Above-mentioned variable outline roughing edger roll pass, the suitable for reading of described pass is 14%-16% with fillet and bottom fillet.
Roughing edger roll pass of the present utility model is variable outline double side wall pass, and strengthened the fillet of pass, lateral pressure amount according to edger roll has suitably reduced depth of groove simultaneously, variable profile pass is in use by becoming sidewall, becoming opening degree, can further guarantee the stability of rolled piece operation, be beneficial to nipping of rolled piece, reduce heap steel-fastening accident, improve the wide control precision of strip, edger roll turning number of times is increased, by fillet at the bottom of the oversized slots, avoid area of stress concentration simultaneously, greatly reduced edger roll roller consumption; Even there is the serious situation of concentrated wear in the edger roll pass, also can reduce stock removal by changing the pass size, edger roll rigidity is strengthened, guaranteed the wide precision of edger roll control.
Description of drawings
Fig. 1 is the structural representation of the utility model starting stage;
Fig. 2 be the utility model terminal stage structural representation.
Mark is as follows among the figure: pass bottom land 1, upper portion side wall 2, lower sides 3, fillet suitable for reading 4, bottom fillet 5, roughing mill rolling centerline 6.
The specific embodiment
Roughing edger roll pass of the prior art is traditional wide plate edger roll pass, and pass is darker, and fillet is less, and only concentrated wear is serious as the edger roll pass, in the turning process, also can only be by the turning of pass original appearance, and the turning amount is bigger.The utility model is changed into variable profile pass with former pass, be variable sidewall variable pitch opening degree pass in the turning process, in use, not only greatly reduce edger roll roller consumption, even and there is the serious situation of concentrated wear in the edger roll pass, also can reduce stock removal by changing the pass size, edger roll rigidity is strengthened, guaranteed the wide precision of edger roll control.
Show among the figure that the variable profile sidewall of pass of the present utility model is divided into two parts up and down, the angle of upper portion side wall and pass axis is greater than the angle of lower sides and pass axis, and promptly the outside opening of upper portion side wall is greater than the outside opening of lower sides.
What Fig. 1 showed is the structural representation of roughing edger roll pass in the starting stage.In the starting stage, suitably reduced depth of groove according to the lateral pressure amount of edger roll, promptly, be decreased to 50mm by 100 original mm at the height of axis direction.
What Fig. 2 showed is the structural representation of roughing edger roll pass in terminal stage.In terminal stage, the edger roll pass is increased to 130mm through the repeatedly turning degree of depth.
Since the degree of depth of edger roll pass by upper portion side wall and lower sides the height addition on the pass axis direction form, therefore change from original state to the process of end-state at the edger roll pass, upper portion side wall is 25-65mm at the height of pass axis direction, and lower sides is 25-65mm at the height of pass axis direction.
In the change procedure of above-mentioned two states, the opening degree of edger roll pass is changed to 235-240mm.
In the above-mentioned two states, the suitable for reading and bottom fillet of pass is increased to 14%-16% by original 10%, and fillet suitable for reading and the bottom fillet of an embodiment who shows among Fig. 1,2 are 15%.
The utility model is in turning process, the variable quantity of top and bottom sidewall can become 65mm by 25mm, and opening degree increases gradually with the increase of turning amount simultaneously, and the variable quantity of opening degree becomes 240mm by 235mm, by the variation of pass size, the turning number of times has increased more than one times.In actual use, not only prolonged roll and used tonnage, made edger roll roller consumption reduce to 0.08kg/t, guaranteed the wide control precision of band steel simultaneously by original 0.2kg/t.
