Tension-free strip steel maglev feeding device and maglev high-speed ultra-thin continuous rolling mill

Abstract

The invention discloses a tension-free strip steel maglev feeding device, which comprises a feeding device frame, on which a first conveyor belt is installed, and the first conveyor belt consists of a first lower transmission roller, a second lower transmission roller and a second transmission roller. A transmission belt is connected, and several positioning magnets are installed on the outer surface of the first transmission belt; a driving device is installed on the feeding device frame, and the driving device is connected with the driving shaft of the first transmission belt. Also disclosed is a maglev high-speed ultra-thin continuous rolling mill equipped with the tension-free strip maglev feeding device, which includes at least two rolling mills, and the rolling mill and the tension-free strip maglev feeding device are installed on the same installation base. As for the feeding device, one magnetic levitation feeding device is installed on both sides of each rolling mill. The tension-free strip steel maglev feeding device can change the way of pulling and feeding the strip steel in the existing rolling mill to the way of pushing the strip steel to convey the strip steel to the rolling mill, which can fundamentally solve the problem that the existing rolling mill cannot roll ultra-thin strip steel problem.

Description

technical field [0001] The invention relates to a tension-free strip steel maglev feeding device and a maglev high-speed ultra-thin continuous rolling mill. Background technique [0002] The thickness of the strip rolled by the existing rolling equipment is greatly limited. The thinnest thickness of the hot-rolled strip is 0.8mm, and the thinnest thickness of the cold-rolled strip is 0.2mm. The reasons are: first, the existing rolling mill is To be able to roll a thinner strip, the diameter of the work roll must be smaller. Work rolls with small diameters are easily bent by the strip steel in the existing tension drawing process, resulting in irregular elastic deformation of the rolls, and there is no precise and successful reverse bending technology to compensate for it. Therefore, cold rolling or hot rolling super Thin strip steel is particularly difficult, and the so-called ultra-thin strip steel rolled out does not have the value of practical application. The second, ...
