Description
Technical Field
The utility model relates to a fluted roller structure for lower fluted roller formula machinery nicking machine belongs to oriented silicon steel production facility technical field.
Background
Oriented silicon steel is a ferrosilicon alloy with preferred grain orientation produced by deformation and recrystallization annealing, and has a silicon content of about 3% and a very low carbon content. The product was a cold rolled sheet or strip with nominal thicknesses of 0.18, 0.23, 0.28, 0.30 and 0.35 mm. The soft magnetic material is mainly used for manufacturing various transformers, fluorescent lamp ballasts and stator cores of steam turbine generators. When the oriented silicon steel is magnetized as a magnetic medium in an alternating current working environment, a part of energy is converted into heat in an electromagnetic conversion process and is lost, and the lost energy is called iron loss. The iron loss comprises hysteresis loss and eddy current loss, and the hysteresis loss refers to inherent loss generated by a ferromagnetic material serving as a magnetic medium under a certain excitation magnetic field; the eddy current loss refers to the loss generated by the core resistance due to the induced current generated by the core when the magnetic flux alternates.
Because the iron loss causes huge waste of energy, in order to reduce the iron loss of the oriented silicon steel, experts at home and abroad make many researches. The method for reducing the iron loss of the oriented silicon steel for the silicon steel material comprises the following steps: increase the silicon content, reduce the plate thickness and refine the silicon steel magnetic domain. The method is characterized in that parallel lines are engraved on the surface of the oriented silicon steel, so that the tissues on the nicks are deformed and dislocated, and residual stress is generated in a non-nicked area, thereby achieving the purposes of refining the magnetic domain and reducing the iron loss.
The existing silicon steel nicks are divided into laser nicks and mechanical nicks, and at present, because of the limitation of laser power, the research of the oriented silicon steel laser nicks still stays in the process experimental research aspect of a laboratory; mature products are lacking in the aspect of mechanical scoring equipment. Mechanical scoring generally suffers from the following problems: 1) the method comprises the steps that a groove set by a process is rapidly realized on the surface of an oriented silicon steel plate, the size of the groove comprises depth, width and space, and the size of the groove cannot be adjusted or is inconvenient to adjust (related parts need to be disassembled and replaced); 2) the working roll directly contacted with the silicon steel is a driving roll, and the working roll and the silicon steel are easy to slip during production, so that the processing quality is influenced.
