Abstract
The utility model discloses oil injection guide plates for a Sendzimir mill. The guide plates are located between strip steel and working rolls. The upper oil injection guide plates are arranged in an inverted splay mode. The lower oil injection guide plates are arranged in a splay mode. An oil injection pipe is arranged on one side of each guide plate. Each guide plate is provided with oil holes. The oil injection guide plates are characterized in that the surface, making contact with the working rolls, of each guide plate is provided with a lining plate; each lining plate is located on the other side of the corresponding oil injection pipe; the length of each lining plate is the same as that of each guide plate; the width of each lining plate is larger than the radius of each working roll; the thicknesses of the lining plates range from 5mm to 8mm. The oil injection guide plates for the Sendzimir mill can effectively prevent the surfaces of the working rolls from being scratched, the placement frequency of the working rolls is lowered, and the surface quality of the strip steel is improved.
Description
Technical field
The utility model relates to a kind of sendzimir mill oil-blooming guide-board, belongs to stainless steel milling equipment field.
Background technology
Sendzimir mill is in the process of rolled steel strip, and must utilize upper and lower two cover oil-blooming guide-boards is injector surface to band steel and roller, and with the Cooling and Lubricator of steel and roller system, guarantee rolling is carried out smoothly.
In order to guarantee the intensity of oil-blooming guide-board, oil-blooming guide-board generally makes cylinder iron.Because upper and lower two cover oil-blooming guide-boards are " falling eight " and " positive eight " layout in milling train.Because working roll hardness HRC is between 60 ~ 62, and cast iron oil-blooming guide-board hardness HRC is between 56 ~ 60, and both hardness are very approaching.Therefore, at dress during working roll, upper and lower oil-blooming guide-board position slightly discomfort or working roll slightly swings, and its end face is easy to contact with working roll roll surface, and scuffing worker rollers is surperficial, causes steel strip surface defect and improper roll change.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of sendzimir mill oil-blooming guide-board, designs a kind of Novel guide plate end face, when dress roller, even work roll surface and oil-blooming guide-board end contact, can scuffing worker rollers roll surface yet.
The technical solution adopted in the utility model is: a kind of sendzimir mill oil-blooming guide-board, guide plate is positioned in the middle of band steel and working roll, upper oil-blooming guide-board is that " falling eight " arranges, lower oil-blooming guide-board is that " positive eight " arrange, guide plate one side is provided with oiling pipeline, guide plate is provided with oilhole, it is characterized in that: the guide plate face contacting with working roll is provided with liner plate, liner plate is positioned at the opposite side of oiling pipeline, the length of liner plate and guide plate equal in length, the width of liner plate is greater than the radius of working roll, and the thickness of liner plate is 5 ~ 8mm.
In such scheme, described liner plate is copper bar or aluminum strip, and hardness is 10 ~ 20HRC.
The working roll hardness HRC of sendzimir mill is between 60 ~ 62, and cast iron oil-blooming guide-board hardness HRC is between 56 ~ 60, and both hardness are very approaching.The utility model is a kind of liner plate little compared with working roll hardness of end face embedding towards working roll at oil-blooming guide-board; and the hardness of setting liner plate is 10 ~ 20HRC; when dress working roll; upper and lower oil-blooming guide-board position slightly discomfort or working roll slightly swings; its end face is easy to contact with working roll roll surface; because liner plate hardness is lower, be difficult for scuffing worker rollers surface, can not cause steel strip surface defect and improper roll change.
The sendzimir mill oil-blooming guide-board that the utility model provides, a kind of material little compared with working roll hardness of end face embedding at oil-blooming guide-board towards working roll, like this, even work roll surface and oil-blooming guide-board end contact, can scuffing worker rollers roll surface yet, can effectively prevent that work roll surface from scratching, reduce working roll and change, improve strip surface quality.
Below in conjunction with drawings and Examples, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (office is cutd open).
Fig. 2 is the top view of Fig. 1.
Fig. 3 is use view of the present utility model.
In figure, 1 is guide plate, and 2 is oiling pipeline, and 3 is liner plate, and 4 is oilhole, and 5 is band steel, and 6 is working roll.
The specific embodiment
Embodiment:
As shown in Fig. 1 ~ 3, a kind of sendzimir mill oil-blooming guide-board, it is middle with working roll 6 that guide plate 1 is positioned at band steel 5, upper oil-blooming guide-board is that " falling eight " arranges, lower oil-blooming guide-board is that " positive eight " arrange, guide plate 1 one sides are provided with oiling pipeline 2, guide plate 1 is provided with oilhole 4, it is characterized in that: 1, the guide plate contacting with working roll 6 is provided with liner plate 3, liner plate 3 is positioned at the opposite side of oiling pipeline 2, the length of liner plate 3 and guide plate 1 equal in length, the width of liner plate 3 is greater than the radius of working roll 6, and the thickness of liner plate 3 is 5 ~ 8mm.
In such scheme, described liner plate 3 is copper bar or aluminum strip, and hardness is 10 ~ 20HRC.
Concrete preparation method is: the utility model is a kind of liner plate little compared with working roll hardness of end face embedding towards working roll at oil-blooming guide-board, and the hardness of setting liner plate is 10 ~ 20HRC, when dress working roll, upper and lower oil-blooming guide-board position slightly discomfort or working roll slightly swings, and its end face is easy to contact with working roll roll surface, after improvement, the liner plate of setting up on guide plate contacts with working roll, because liner plate hardness is lower, be difficult for scuffing worker rollers surface, can not cause steel strip surface defect and improper roll change; Can effectively prevent that work roll surface from scratching, reduce working roll and change, improve strip surface quality.
Claims (2)
