Rolling mechanism used in magnetic levitation superconductivity rolling mill

Abstract

The invention relates to a rolling mechanism used in a magnetic levitation superconductivity rolling mill. The rolling mechanism is characterized in that a plurality groups of support roller holes, free roller holes and working roller holes which are arranged longitudinally are formed in a machine body; permanent magnetic iron grooves are symmetrically formed in the upper parts of the support roller holes and two sides of the support roller holes, the free roller holes and the working roller holes; permanent magnets are mounted inside the permanent magnetic iron grooves and are sealed through permanent magnetic groove covers; the support rollers, the free rollers and the working rollers are respectively inserted into the support roller holes, the free roller holes and the working roller holes and are assembled on the roller hole covers at two ends of the roller holes through bearing pedestals; one end of each working roller is connected with the output shaft of a motor; air cooling chambers are formed outside each groups of the support roller holes, the free roller holes and the working roller holes; the air cooling chambers are communicated with the outside through nitrogen conveying tubes. The rolling mechanism has the characteristics of novel structure, simplicity and convenience for machining, cost reduction, improved efficiency and product quality, prolonged service life of equipment, and the like.

Description

technical field [0001] The rolling mechanism for a magnetic levitation superconducting rolling mill of the present invention relates to a rolling mechanism of a magnetic levitation strip rolling mill. Background technique [0002] Plate and strip rolling mill is a common production equipment in steel production enterprises. The role of the roll in the rolling mill cannot be replaced, but the occurrence of roll deformation cannot be avoided. The deformation of the roll causes problems such as uneven thickness and wavy edges of the plate; In order to avoid the occurrence of these problems, some rolling mills have increased backup rolls or fixed rolls on both sides of the rolls to prevent the deformation of the rolls; but this structure can not avoid the deformation of the work rolls, but also increases the production and maintenance costs of the rolling mill. [0003] The existing rolling mill adopts a water-cooling method to cool the roll, and the cooling water or cutting flu...
