Description

Online cleaning device for working roller

Technical Field

The utility model relates to the field of metallurgical equipment, in particular to an online cleaning device for a working roll.

Background

In the steel industry, with the development and maturity of ESP technology (strip steel endless continuous casting and rolling technology) and casting and rolling technology, the quality and performance of the hot rolled finished product can be improved after flattening and the like deep processing, and the market competitiveness of the product is improved. At present, a new leveling machine set is arranged after an ESP or a cast rolling line, and on a leveling machine of the machine set, as the surface of hot rolled strip steel has more oxidized iron scales, the hot rolled strip steel is often easy to be adhered to a working roll of the leveling machine, and the steel slag on the surface of the working roll is copied on finished strip steel again, so that the quality of a machine set product is seriously influenced. Therefore, an effective device for cleaning the roller surface of the working roller is needed to solve the problem of foreign matters sticking to the working roller.

Disclosure of Invention

The utility model aims to solve the problems and provides an online cleaning device for a working roller.

The utility model adopts the following technical scheme:

an online cleaning device for a work roll, comprising: the upper working roll scraper module and the lower working roll scraper module comprise scraper blades, clamping cylinders used for fixing the scraper blades, swing cylinders used for driving the clamping cylinders to swing and installation bases used for fixing the swing cylinders.

Further, the upper working roll scraper module and the lower working roll scraper module are both arranged on one side of the strip steel outlet.

Further, an ash receiving disc is arranged between the lower part of the upper working roll scraper module and the upper part of the strip steel.

Further, the doctor blade is made of a carbon fiber composite material.

Further, the installation base is fixed on the bearing seat of the working roll at two sides of the upper working roll or the lower working roll through bolts.

Further, the swing cylinder includes two, installs respectively in the both ends of clamping cylinder, and two swing cylinders are all fixed on two installation bases through U type bolt.

By adopting the technical scheme, the utility model can better solve the problems of bonding scale and other impurities on the surface of the working roller, improve the cleanliness of the surface of the working roller, improve the product quality and improve the production environment of the unit.

Detailed Description

For further illustration of the various embodiments, the utility model is provided with the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments and together with the description, serve to explain the principles of the embodiments. With reference to these matters, one of ordinary skill in the art will understand other possible embodiments and advantages of the present utility model. The components in the figures are not drawn to scale and like reference numerals are generally used to designate like components.

The utility model will now be further described with reference to the drawings and detailed description.

The embodiment discloses an online cleaning device for a working roll, which comprises an upper working roll scraper module and a lower working roll scraper module as shown in figures 1-3. Wherein, upper working roll scraper module and lower working roll scraper module all include doctor blade 1, be used for fixed doctor blade's 1 clamping cylinder 2, be used for driving clamping cylinder 2 to swing the swing cylinder 3 and be used for fixed swing cylinder's 3 installation base 4.

The doctor blade 1 is of an elongated shape having a length approximately equal to the length of the work roll 6, in this embodiment a carbon fiber composite material. The doctor blade 1 is fixedly arranged on the side wall of the clamping cylinder 2, the clamping cylinder 2 is driven to move through two swinging cylinders 3 connected with two ends of the clamping cylinder, and the two swinging cylinders 3 are fixed on two mounting bases 4 through U-shaped bolts.

The upper working roll scraper module and the lower working roll scraper module are both arranged on one side of an outlet of the strip steel, the upper working roll scraper module is fixedly arranged on an upper working roll bearing seat 5, the lower working roll scraper module is fixedly arranged on the upper working roll bearing seat 5, and particularly, the installation base 4 is fixed on the working roll bearing seats 5 on two sides of the working roll 6 through bolts. The mounting positions of the upper working roll scraper module and the lower working roll scraper module are both on the outlet side of the strip steel, and the swinging air cylinder 3 can be driven to enable the scraper blade 1 to be close to the working roll 6 and far away from the working roll 6.

An ash receiving disc 7 is arranged between the lower part of the upper working roll scraper module and the upper part of the strip steel and is used for receiving impurities such as iron powder scraped by the scraper blade 1 in the upper working roll scraper module and preventing the impurities from falling on the surface of the strip steel again. The impurities removed by the lower working roll scraper module directly fall on the ground below the strip steel.

In this embodiment, when the leveler is not put into or after the input, the work roll 6 surface is free from binding impurities, the work roll doctor module does not work, and the doctor blade 1 is not close to the work roll 6 surface. After the surface of the working roll 6 is adhered with impurities such as iron powder, the working roll scraper module is put into operation, the swinging cylinder 3 swings for a certain angle, the doctor blade 1 is guaranteed to be just close to the surface of the working roll 6, and the impurities adhered to the surface of the working roll 6 can be effectively removed due to the fact that the doctor blade 1 is opposite to the rotating direction of the working roll 6, and the surface of the working roll 6 is guaranteed to be clean. Meanwhile, the scraped impurities cannot fall on the surface of the strip steel, and secondary pollution is avoided.

Under normal use conditions, the device can effectively remove impurities such as bonded iron powder on the surface of the working roller 6, and is convenient to install and simple to operate. The roller surface is not damaged, and the quality of the strip steel is not negatively affected.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
