Problems solved by technology

[0007] The existing four-high rolling mills are mostly used for synchronous rolling of large work roll diameters, which cannot roll thin strips or extremely thin strips; the roll system is vertically distributed, and it is difficult to roll liquid, powder and granular metal raw materials; the existing asynchronous rolling mills The replacement of different speed ratios depends on the replacement of transmission gears, which is costly and inefficient, and the existing rolling mill rolls are all formed at one time, cannot be changed and disassembled, and have a single range of use
The current thin strip and ultra-thin strip production equipment in the state of metal, alloy and powder state cannot meet the demand, and the present invention is proposed under this background

Embodiment 1

[0052] The four-roller vertical distribution rolling mill includes a pressing device 1, a pair of vertically distributed work rolls 3 and a pair of support rolls 2, a archway 4 and a base 10, a tension motor 5, a main drive motor 7, a drum 8 and a tension roll 9. The archway 4 is fixed on the base 10 by bolts on the contact surface 15 between the archway and the base in a vertical arrangement. Both ends of the roll are fixed by sliding bearing seats, and the roll and bearing seats move at the same time. The bearing seats of the upper backup roll 2 are balanced by The beam 18 is hoisted, the bearing seat of the lower back-up roll 2 is fixed at the bottom of the archway 4, the bearing seats of the upper and lower work rolls 3 are connected by a spring 19 between the work rolls, and the upper surface of the bearing seat of the lower work roll 3 has holes and grooves, so that the springs between the work rolls 19 is fixed inside, the upper end of the spring 19 between the work roll...

Embodiment 2

[0056] The two-roll horizontally arranged rolling mill is composed of two work rolls 3 arranged horizontally on the left and right, the archway 4 and the base 10, the main drive motor 7, the feeding port 11 and the discharge port 12, and the archway 4 passes through the two-roller horizontally arranged archway. The contact surface 14 with the base is fixed on the base 10 by bolts. The work rolls 3 are the work rolls 3 in the four-roll vertical arrangement after disassembly, and the backup rolls 2 in the four-roll vertical arrangement are used as the work rolls 3 in the two-roll horizontal arrangement.

[0057] Start the power supply of the rolling mill system. During rolling, liquid, powder or particles are sent into the roll gap through the feeding port, and the finished strip is obtained after rolling.

Embodiment 3

[0059] The two-roll vertically arranged rolling mill is composed of a pressing device 1, a pair of vertically distributed work rolls 3, an archway 4 and a base 10, a tension motor 5, a main drive motor 7, a reel 8 and a tension roll 9; The work roll 3 is the work roll 3 of the four-roll vertical arrangement after disassembly, and the backup roll 2 in the four-roll vertical arrangement is used as the work roll 3 in the two-roll vertical arrangement. The archway 4 is vertically arranged The arch and the base contact surface 15 are fixed on the base 10 by bolts.

[0060] Start the power supply of the rolling mill system, and carry out synchronous or asynchronous rolling and forming of the thin strip billet. The rolling process is carried out under the condition of strip tension. After multiple passes of repeated rolling, the thickness range is below 0.05mm, until it is below 0.005mm. Finished functional material for thin strips.

Abstract

The invention relates to a multifunctional rolling mill for producing thin metal straps and ultra-thin metal straps and belongs to the field of metal rolling devices. The multifunctional rolling mill comprises a pressing-down device, a memorial archway, a base, a roll system, a roll gap adjusting device, a main transmission motor and a tension motor. The memorial archway is fixed on the base through a bolt, the pressing-down device is fixed on the memorial archway through a pressing-down lead screw, the roll system is placed in the memorial archway, a bearing seat limits horizontal movement of the roll system, the roll system can vertically slide in a memorial archway window, the roll gap adjusting device uplifts a spring through the pressing-down lead screw and a balance beam to be connected with the memorial archway, the main transmission motor is connected with the roll system through a universal spindle, the tension motor is fixed on the base through a bolt, and the roll system adopts a four-roller vertical distributing mode, a two-roller vertical distributing mode or a two-roller horizontal distributing mode. The multifunctional rolling mill can be used for rolling liquid, powdery and particle-shaped ultra-thin metal and alloy strap materials and has a continuously variable function, a stepless adjusting function and a function of optionally selecting transmission speed ratio of vertical rollers.
