Magnetic suspension superconductive steel rolling machine

Abstract

The invention discloses a magnetic suspension superconductive steel rolling machine. A piston is connected with a frame through a thread. A cylinder body is connected with an upper rolling and pressing mechanism. The oil pressure pushes the upper rolling and pressing mechanism to move forwards and backwards along guide rails fixed to the two sides of the frame. Cooling is conducted through liquid nitrogen. The central line of a supporting roller and the central line of a working roller are kept parallel by adjusting the magnetic force of a permanent magnet. A steel plate to be rolled and pressed is flatly placed on a magnetic suspension rolling and pressing platform in the width direction of the working roller. The rotary central line of the rolling and pressing platform intersects with the central line of the working roller. The rolling and pressing platform supports the steel plate to be rolled and pressed and squeezes the working roller. The permanent magnet is installed under the rolling and pressing platform. Permanent magnetic repulsive force is generated between the rolling and pressing platform and a powered electromagnet, so that the rolling and pressing platform bears rolling and pressing force to be suspended. An external power driving shaft drives an inner permanent magnet to rotate, and an outer permanent magnet is coupled to rotate, so that the rolling and pressing platform is driven to rotate. Friction is generated between the rolling and pressing platform and the steel plate to be rolled and pressed through the rolling and pressing force of the working roller, and the rolled steel plate is pushed to move forwards. The magnetic suspension superconductive steel rolling machine has the advantages that the roller peak, the working roller which is used for plane rolling and adjusted through magnetic force and the supporting roller are parallel, and a permanent magnetic coupler drives the rolling and pressing platform to rotate so that the rolled steel plate can be pushed.

Description

technical field [0001] The technology of the invention mainly relates to the field of steel rolling equipment, in particular to a magnetic levitation superconducting steel rolling machine. Background technique [0002] At present, the rolling mills used in steel rolling machines all use upper and lower work rolls to simultaneously roll and press steel plates. The rolling mill has structures such as lower work rolls and lower support rolls, which increases the cost of manufacturing and maintenance of the equipment, and the deformation of the upper and lower work rolls causes the plate to appear. Problems such as uneven thickness, wave bending and warping; in order to avoid these problems, some rolling mills have added backup rolls or fixed rolls on both sides of the work rolls to prevent deformation of the work rolls; but this structure also cannot avoid the work rolls The deformation, but also increased the cost of production and maintenance of the rolling mill. At the same...
