Method for Improving Product Quality of Amorphous Strip Production

Abstract

The invention relates to a method for improving the product quality in amorphous strip production. The method is characterized by comprising the following steps: (1) setting a plurality of sets of sensors and length encoders above a strip running on shunt winding equipment; (2) carrying out shunt winding on the strip on the shunt winding equipment to obtain small rolls, wherein a unique identification code is generated on each roll; (3) during the shunt winding of the shunt winding equipment, transmitting a multipoint thickness value in the width direction of the strip to a control system, establishing data information of strip thickness, and uploading the data information to a database; (4) taking a test sample to carry out electromagnetic performance testing before or after the shunt winding of the strip, and uploading electromagnetic performance testing data to the database of the strip of a server after testing; and (5) during the operation of roll folding, matching out a plurality of optimal small rolls to carry out strip folding operation according to qualified small rolls in the database by the control system. According to the method, the optimization of roll folding can be realized, the operation is convenient, the production efficiency is improved, and the quality of finished products when amorphous strips leave factories is improved.

Description

technical field [0001] The invention relates to a method for improving the quality of products produced from amorphous strips, in particular to a method for improving the lamination coefficient of amorphous strip products, and belongs to the technical field of production of amorphous alloy materials. Background technique [0002] Amorphous alloy, or metallic glass, is a new technology that came out in the 1970s. It uses quenching technology to form molten steel into a thin strip with a thickness of about 25-30 microns at one time. The solid alloy (thin strip) obtained from FeSiB is different from the crystal structure in which atoms are arranged regularly in cold-rolled silicon steel materials. It is this alloy whose atoms are in an amorphous structure that is randomly arranged, making it have a narrow B-H loop , has the characteristics of high magnetic permeability and low loss; at the same time, the irregular arrangement of amorphous alloy atoms restricts the free passage ...

Problems solved by technology

When 5-layer lamination, if the finished product is directly rolled, the thickness difference between the left and right sides of the finished product (the tightness of the left and right sides) will be greater, which will greatly affect the product quality

[0015] To sum up, it can be known that when the current strip is combined, since there is no corresponding strip physical data and electromagnetic performance data provided to the operator, the operator draws small coils based on experience or randomly, and the product quality of the finished strip Difficult to optimize and difficult to guarantee product quality
