Abstract
The invention discloses a kind of methods for preventing ball press roller sizing, include: step 1: being respectively mounted graphite and round brush on the outside of two rollers of ball press, round brush side is contacted with the discharge port of graphite, and the round brush other side is contacted with roller, and graphite is provided with graphite powder；Step 2: first starting ball press before pressure ball, under the drive of roller, round brush is in reverse to roller turn；Step 3: when the round brush approach graphite of rotation, the graphite powder in graphite adheres to round brush surface layer, and the round brush of rotation again paints the graphite on surface layer on the surface of roller；Step 4: after roller surfaces are all brushed with one layer of graphite powder, opening the blanking device supply mixture of ball press to start pressure ball operation to produce green-ball.Using this method of the invention, green-ball moisture content can also be improved while effectivelying prevent ball press roller sizing, thus improves green ball strength and green-ball balling ratio.
Description
Technical field
The present invention relates to green-ball preparation technical field, in particular to a kind of method for preventing ball press roller sizing.
Background technique
Ball press is widely used in the preparation of the green-ball of rotary hearth furnace direct-reduction pelletizing.Due to the need by green-ball subsequent production
It wants, the intensity and balling ratio that green-ball needs to have certain.According to knowhow, the case where not considering ball press roller sizing
Under, the moisture size of the yield rate of green-ball, intensity and green-ball is closely bound up, and green-ball moisture is bigger, and green ball strength is higher, green-ball at
Ball rate is higher, on the contrary then opposite.But the fact is that ball press roller just will appear viscous after green-ball moisture content is greater than 15%
Expect phenomenon, and with the increase of green-ball moisture content, ball press roller sizing situation is more serious.Ball press roller sizing is tight
When heavy, it has to shut down cleaning, this not only influences normally to produce, and needs to remove ball press roller when cleaning, manually
Cleaning, large labor intensity, time-consuming.Therefore, in order to avoid ball press roller sizing, generally the moisture of green-ball is controlled in production
15% hereinafter, but gained green ball strength is poor in this case, balling ratio is lower.
Therefore, according to the current prior art, if improving green-ball moisture content to improve yield rate, the intensity of green-ball,
Ball press roller sizing can then occur, influence normal production operation；It and is to prevent ball press roller sizing from then having to reduce life
Ball moisture content can reduce yield rate, the intensity of green-ball in this way.
Summary of the invention
It is an object of the invention to overcome above-mentioned technical problem, a kind of method for preventing ball press roller sizing is provided, benefit
With this method, green-ball moisture content can also be improved while effectivelying prevent ball press roller sizing, it is strong thus to improve green-ball
Degree and green-ball balling ratio.
To achieve the goals above, a kind of method preventing ball press roller sizing provided by the invention includes:
Step 1: being respectively mounted graphite and round brush, the discharging of round brush side and graphite on the outside of two rollers of ball press
Mouth contact, the round brush other side are contacted with roller, and graphite is provided with graphite powder；
Step 2: first starting ball press before pressure ball, under the drive of roller, round brush is in reverse to roller turn；
Step 3: when the round brush approach graphite of rotation, the graphite powder in graphite adheres to round brush surface layer, the round brush of rotation
The graphite on surface layer is painted on the surface of roller again；
Step 4: after roller surfaces are all brushed with one layer of graphite powder, open ball press blanking device supply mixture to
Start pressure ball operation to produce green-ball.
Further, in the above-mentioned method for preventing ball press roller sizing, the length of graphite and the length of round brush are equal
It is set as not less than ball press roller length.
Further, in the above-mentioned method for preventing ball press roller sizing, the length of round brush is equal to graphite
Discharge port length.
Further, in the above-mentioned method for preventing ball press roller sizing, the discharging of round brush side and graphite is tight-lipped
Contiguity touching when round brush rotates, drives the graphite powder in graphite to round brush surface layer；When round brush is static, the discharging of graphite is blocked
Mouthful.
Further, in the above-mentioned method for preventing ball press roller sizing, the granularity of graphite powder is 28um or less.
Further, in the above-mentioned method for preventing ball press roller sizing, the granularity of graphite powder is 45um or less.
Further, in the above-mentioned method for preventing ball press roller sizing, the granularity of graphite powder is 75um or less.
The present invention is simple, easy, and the characteristic lubricated using graphite powder exquisiteness is transferred to pressure ball in ball press roller by round brush
The graphite powder a thin layer of in roller surfaces brush before region, to play the purpose for preventing ball press roller sizing；Round brush is tight
Close to be contacted with roller, by frictional force, round brush does not need to provide additional power device with roller reverse movement；Round brush and stone
The graphite powder discharge port of print cartridge is in close contact, round brush rotation, and the graphite powder in graphite is adhered to round brush surface layer via discharge port,
When round brush is static, round brush plays the role of blocking graphite discharge port.
After the method provided by the invention for preventing ball press roller sizing, due to not having to consider further that ball press roller is viscous
The influence factor of material, therefore green-ball moisture content can be increased to 16%~20% from 15%, thus it is strong that green-ball can be improved
Degree and green-ball balling ratio.In addition, green-ball binder can at least drop when green-ball moisture content is increased to 17%~18%
Low 50% or more, this can greatly reduce green-ball production cost.
