Description
Technical field
The invention belongs to plate hight speed rolling field as thin as a wafer, be specifically related to a kind of method that prevents vibration of steel bar under high-speed rolling station of ultra-thin plate.
Technical background
The mill speed of modern cold continuous rolling generally at 1500m/min between the 3000m/min, produce the cold continuous rolling of plate as thin as a wafer (0.4mm following for plate) as thin as a wafer, consider that from production efficiency ordinary production speed is higher than common cold-reduced sheet again.Milling train under the effect of various perturbed forces, is easy to occur frequency tripling or five frequency multiplication flutters in the rolling process of plate as thin as a wafer, by tension force between frame, pass to continuous frame, causes system vibration, causes the serious overproof even broken belt of tape thickness, damage equipment.Therefore, stable tension control is the rolling key of plate as thin as a wafer.
On the other hand, the band steel inevitably can agitation air in the high-speed rolling process, forms air-flow.For plate as thin as a wafer, air-flow can cause plate vibration as thin as a wafer, and then causes tension fluctuation, has a strong impact on the normally rolling of plate as thin as a wafer.
Summary of the invention
The object of the present invention is to provide a kind of method that prevents vibration of steel bar under high-speed rolling station of ultra-thin plate, this method can prevent vibration of steel bar under high-speed rolling station of ultra-thin plate.
To achieve these goals, technical scheme of the present invention is: a kind of method that prevents vibration of steel bar under high-speed rolling station of ultra-thin plate, it is characterized in that: three roller stabilising arrangements are set up in the first frame porch in tandem mills, three roller stabilising arrangements comprise the lower-left roller, bottom right roller and a last intermediate calender rolls, last intermediate calender rolls is positioned at the lower-left roller, on the roller centre, bottom right, and the last intermediate calender rolls of three roller stabilising arrangements is positioned on the roll line, the lower-left roller of three roller stabilising arrangements, the bottom right roller is positioned under the roll line, the band steel is from the last intermediate calender rolls and the lower-left roller of three roller stabilising arrangements, pass between the roller of bottom right, last intermediate calender rolls is by the Driven by Hydraulic Cylinder lifting, normal when rolling, last intermediate calender rolls is depressed and is pushed down the band steel; Set up the anti-device that quivers of single roller in last frame exit of tandem mills, being positioned under the roll line of the vibration-resistant roller of the anti-device that quivers of single roller, normal when rolling, vibration-resistant roller is stretched out by Driven by Hydraulic Cylinder, tightens the band steel.
Be respectively equipped with guiding gutter on the surface of the last intermediate calender rolls of described three roller stabilising arrangements, lower-left roller, bottom right roller.The surface of described vibration-resistant roller is provided with guiding gutter.
The invention has the beneficial effects as follows: three roller stabilising arrangements are set up in the first frame porch in tandem mills, and the band steel is depressed from passing afterwards last intermediate calender rolls between the last intermediate calender rolls of three roller stabilising arrangements and the left and right sides lower roll; Set up the anti-device that quivers of single roller in last frame exit of tandem mills, normal when rolling, the vibration-resistant roller of the anti-device that quivers of single roller is stretched out by Driven by Hydraulic Cylinder, tightens the band steel; In the porch of tandem rolling unit and the control of exit tension force, set about simultaneously, solve vibration of steel bar under high-speed rolling station of ultra-thin plate; The present invention has alleviated plate vibration as thin as a wafer, and its effect is remarkable.The present invention descends the control of the stable rolling and thick difference of strip to bring significant effect at a high speed for the band steel.
Be respectively equipped with guiding gutter on the surface of the last intermediate calender rolls of three roller stabilising arrangements, left and right sides lower roll and vibration-resistant roller, rationally derive air-flow, fundamentally eliminate the vibration of band steel.
