[16] The present invention relates to a calibration apparatus for use in a rolling process, and more particularly to a scale breaker apparatus for straightening the strip and breaking the scale layer of the strip surface.
[17] As shown in FIG. 3, during the production of stainless hot rolled coils, the scale breaker facility installed at the front of the descaler facility moves the upper work roll 2 downward using the cylinder 4 so that the upper work roll 2 and the lower work piece are moved. While the work rolls 4 intersect, the strips S are bent into a "V" shape by the upper and lower work rolls 2 and 4 to correct the flatness of the strips S, and at the same time, It is installed to improve pickling properties by crushing the scale layer.
[18] However, when the upper work roll 2 is raised and lowered, the left and right sides of the upper work roll 4 are always raised and lowered horizontally to give only a uniform reduction amount. In this case, flatness correction is not performed.
[19] In addition, the camber strip enters the pickling line installed at the rear end and passes through the brush roll, causing brush roll wear and roll marks due to poor flatness. There are many problems in deterioration of quality and productivity, such as pressing on the roll to shorten the roll life and generating a roll mark.
[20] The present invention has been made to solve the above problems, and an object of the present invention is to attach a pressure reduction device to the work breaker upper work roll which gives only a uniform reduction amount, and the crushed scale is attached to the work roll and the backup roll. It is to provide a scale breaker device that can be prevented.

Top brush roll 36.
[32] Both ends of these rolls are installed in the tilt block 28 and the other moving block 18b through bearings, and the degree of the tilt block 28 is increased by about ± 1 to about when the tilt block 28 is lifted up and down using the tilt cylinder 26. 2mm.
[33] Here, the upper work roll 30 is in direct contact with the strip S, the upper small back up roll 32 and the upper large back up roll 34 support the upper work roll 30, the upper brush roll 36 Is in contact with the upper large backup roll 34 to remove the foreign matter.
[34] The lower work roll 38, the lower small back up roll 40, and the lower large back up roll, respectively, are located at the lower side of the strip S, that is, the lower side of the front side and the lower side of the tilt adjusting unit 20 based on the strip S. The 42 and the lower brush roll 44 are installed with the both ends supported by the roll base 46.
[35] The removal unit 50 is connected to the high pressure water line 52 and the high pressure water line 52 installed on the outer surface of the moving block 18 as shown in FIG. A V-type spray head 54 and an I-type spray head 56 positioned therebetween, and an I-type spray head 58 positioned between the lower small back-up roll 40 and the lower large back-up roll 42 are included.
[36] The high pressure water line 52 is provided with a solenoid valve 52a to adjust the amount of high pressure water supplied.
[37] By forming the bent direction of the V-type spray head 54 to the outside and the spray angle toward the outside, the scale separated by the sprayed high-pressure water is pushed outward of the strip S.
[38] In addition, all the above-described small backup rolls 32 and 40 are formed with slanted grooves, and the crushed scale flows into these grooves to the work rolls 30 and 38 or the large backup rolls 34 and 42. Prevents roll marks from forming.
[39] In addition, the brush roll 44 also contacts the front and rear lower back-up rolls 42 to wipe the surface of the back-up rolls 42.
[40] As shown in FIG. 1, the moving part 60 installs the pinion roll 62 at the lower four corners of the base frame 12, and the pair of pinion rolls 62 are rotated together by the rotation shaft. 62 is installed in engagement with the rack gear 64a of the rail 64.
[41] In addition, a rod end of the moving cylinder 66 is fixed at the lower center of the base frame 12 to move the base frame 12 to the left and right.
[42] In addition, a sensor guide 70 having a strip detecting sensor 70a and an alarm detecting sensor 70b is installed at both edges of the strip, and the sensors are connected to the control panel 72 to remotely operate the operator. Adjustment is possible.
[43] The drain line 74 is installed at one side of the lower side of the base frame 12 to drain the injected high pressure water.
[44] The scale breaker device according to the present invention configured as described above exhibits the following actions.
[45] First, the upper cylinder 14 is operated to lower the one side moving block 18a and the other side moving block 18b to contact the strip S and the upper work roll 30.
[46] At this time, the rack rod 24 and the pinion gear 12a located on both sides of the upper cylinder 14 precisely control the vertical movement distance of the one side moving block 18a and the other side moving block 18b.
[47] If either of the edges of the strip S has been stretched by the camber phenomenon, the calibration operation may be carried out with the tilt cylinder 26 so that the upper work roll 30 and the lower work roll 38 can contact the extended portion of the strip S. ) To lower or raise the tilt block 28.
[48] That is, since the tilt cylinder 26 is installed only on one side of the moving block 18a and fixed to the hinge shaft 22 on the other side, when the tilt cylinder 26 is raised, the side with the hinge shaft 22 is lowered and the tilt is reversed. Lowering the cylinder 26 lowers the upper work roll 30 toward the tilt cylinder 26 and corrects the stretched portion of the strip edge portion.
[49] The diagonal groove formed on the surface of each of the small backup rolls 32 and 40 has a broken scale entering the groove, and the upper and lower large backup rolls 34 and 42 engaged with the upper and lower small backup rolls 32 and 40, respectively. Or roll marks that are generated due to scale compression on the upper and lower work rolls 30 and 38 surfaces.
[50] In addition, since the high-pressure water is injected from the I-type spray heads 56 and 58 installed in front of the upper and lower small back-up rolls 32 and 40, the roll surface can be kept clean at all times.
[51] Brush rolls 36 and 44 provided on the side of each of the large backup rolls 34 and 42 are installed to remove the scale by wiping the surface of the large backup roll.
[52] The V-type spray head 54 facilitates peeling of the scale, and detects both edges of the strip by the strip detecting sensor 70a attached to the sensor guide 70, and moves the cylinder 66 by the action of the control panel 72. ).
[53] Then, the scale breaker device operates at the correct point at all times while the entire base frame 12 is moved, and when the strip pull occurs excessively, the alarm detection sensor 70b outputs a line start stop signal.
[54] As described above, the present invention facilitates the descaling and flatness correction of the stretched portion of the strip by tilting the tilt block up to the tilt cylinder.
[55] In addition, an oblique groove is formed on the surface of the small back-up roll to prevent a roll mark from being generated.
[56] In addition, by using the I-type spray head to remove the scale peeled off with high-pressure water and at the same time to remove the scale of the large back-up roll with a brush roll it is possible to achieve the effects of preventing the roll mark, improve pickling properties and extend the roll life.
