Problems solved by technology

[0003] In view of this, the object of the present invention is to provide a plate shape control roll group and a strip rolling mill to solve the problem of the roll bending technology used in the current conventional strip rolling mill, increase the load of the rolls and the wear and tear of parts, and reduce the increase in the middle of the six-high rolling mill. Roll and bending technology to control the plate shape and other technical issues, realize the direct adjustment of the upper and lower support rolls and the upper and lower work roll gap shape, and directly control the force deformation and plate shape of the roll

Embodiment 1

[0029] Such as Figure 1-3 As shown, in the present embodiment, the plate type control roll group is set on a four-roll strip mill, which includes a frame 1, a hydraulic cylinder 2 for pressing, an upper back-up roll 4, an upper work roll 5, The lower work roll 6, the lower support roll 7, the lower beam 9, the upper beam 10, the balance device 11 and the upper hydraulic cylinder 13, the lower hydraulic cylinder 2 is installed on the frame 1, and the two ends are provided with bearing seats ( On the upper support roller 4 of unmarked), the upper hydraulic cylinder 13 is installed on the frame 1, and acts on the lower support roller 7 with bearing seats (unmarked) at both ends, and the bearing seats are all installed on the frame And the gap is adjusted by the pressing hydraulic cylinder (unmarked) arranged on the side; the upper support roll 4 is used to support the upper work roll 5, the lower support roll 7 is used to support the lower work roll 6, and the balance device 11 ...

Embodiment 2

[0034] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the above-mentioned plate shape control roll group is applied to the two-roll strip mill, that is, the upper support roll 4 and the lower support roll 7 are not provided, and the upper support roll is controlled The oil cylinder 12 controls the upper control roll 3 to directly act on the upper work roll 5 , and the lower control oil cylinder 14 controls the lower control roll 8 to directly act on the lower work roll 6 .

Embodiment 3

[0036] Such as Figure 4As shown, the difference between this embodiment and Embodiment 1 is that the four-high strip mill is transformed from a six-high strip mill, that is, the upper and lower intermediate rolls of the six-high strip mill are removed and controlled from the top. The oil cylinder 12 provides different control pressures and positions for the upper support roller 3 to act on the upper support roller 3, and the upper control cylinder 12 controls the upper control roller 3 to act on the upper support roller 4, and the lower control cylinder 14 controls the lower control roller 8 to act The roller 7 is supported underneath.

Abstract

The invention discloses a plate type control roller group and a plate strip rolling mill, and belongs to the technical field of metallurgical machinery design and manufacturing. The plate type controlroller group comprises an upper control roller and a lower control roller, wherein the upper control roller is arranged above an upper roller of the plate strip rolling mill, the two ends of the upper control roller are each provided with an upper control oil cylinder connected with an upper cross beam of the plate strip rolling mill, the lower control roller is arranged below a lower roller of the plate strip rolling mill, the two ends of the lower control roller are each provided with a lower control oil cylinder connected with a lower cross beam of the plate strip rolling mill, the upper control oil cylinders provide control pressure and position acting on the upper roller to the upper control roller, and the lower control oil cylinders provide control pressure and position acting on the lower roller to the lower control roller. By respectively adjusting the pressures and the positions of the upper control roller and the lower control roller, the purposes of directly adjusting theroller gap shapes of an upper support roll, a lower support roll, an upper working roller and a lower working roller, and controlling the roller deformation and the rolling plate shape of the plate strip rolling mill are achieved.

Description

technical field [0001] The invention belongs to the technical field of strip rolling mills used in the metallurgical machinery industry, and in particular relates to a strip shape control roll group and a strip rolling mill. Background technique [0002] At present, the medium and heavy plate mills and strip coil mills used in the metallurgical machinery industry are basically conventional two-roll mills, four-roll mills, and six-roll mills. Each side of the roll is equipped with a bending force of about 100-500 tons, or the axial movement of the roll, grinding the roll shape curve, etc. The disadvantages are: increased roll load, a rolling mill added roll bending oil cylinder + roll axial movement oil cylinder (about 16+4=20 oil cylinders in total), or special roll curve grinding; The size of the roll, such as the diameter of the support roll of a 5-meter-wide rolling mill is 2.0-2.4 meters, and the thickness of the surface layer of the roll is about 50-100 mm, which will ...
