Abstract

An amorphous strip heat treatment take-up and pay-off system comprises a strip pay-off disc and a strip take-up disc which are installed on a machine frame and driven by a motor, a transition disc is further installed on the machine frame in a rotating mode, the transition disc is in a groove wheel shape, a plurality of radial air holes are formed in the circumferential face of the transition disc, and the air holes are communicated with an inner cavity of the transition disc. The center of the transition disc is connected with a rotary joint, the rotary joint is communicated with an inner cavity of the transition disc, a fixed portion of the rotary joint is connected to a vacuum generation device, a front roller and a rear roller are arranged at the position close to the transition disc, a strip from the strip pay-off disc bypasses the front roller, then bypasses the transition disc and then bypasses the rear roller and then is conveyed backwards, and the transition disc is rotationally installed on the machine frame through a rotating shaft. The control method of the amorphous strip heat treatment take-up and pay-off system adopts the amorphous strip heat treatment take-up and pay-off system. The invention is good in trial effect in practice.

Description

technical field [0001] The invention relates to the processing of amorphous and nanocrystalline strips, in particular to a constant speed and constant tension system and a control method in the processing of amorphous and nanocrystalline strips, and belongs to the technical field of high-end magnetic core production and manufacturing. Background technique [0002] Magnetic cores used in electric meters require low magnetic permeability, low loss, DC resistance, and stable performance. The material can meet this requirement by annealing (heat treatment) the amorphous and nanocrystalline strips. Patented in China Application numbers 2006800267143 and 2014101224230 have disclosed this process in more detail. In this process, the temperature during the return process, the tension on the strip, and the speed of the strip have a decisive impact on the properties of the obtained strip. Both of the above two documents mentioned that annealing should be carried out within a certain t...
