Method for judging quality of oriented silicon steel sutured seam

Abstract

The invention discloses a method for judging the quality of an oriented silicon steel sutured seam; the quality of the sutured seam can be quickly judged according to conditions of removed tooth, broken teeth, tooth length, overlap quantity and deviation of unilateral width of the suture seam; the method can find out a suture seam with poor quality in time, performs re-suture in time, reduces thespeed-down shutdown or even band breakage caused by rewinding re-suturing, ensures the stable operation of the unit, and increases the unit output. After only observing and measuring need to be performed according to the standards, the quality of the suture seam can be judged, the breakage and shutdown caused by the suture seam can be effectively reduced, and the ability of stable operation of theunit can be improved; the field operation is simple, fast and strongly pertinent, and the method has good promotion value.

Description

technical field [0001] The invention relates to the technical field of seam quality detection, in particular to a method for judging the seam quality of oriented silicon steel. Background technique [0002] Oriented silicon steel is an electrical steel in which the easy magnetization direction of grains is parallel to the rolling direction and the silicon content is about 3%. Oriented silicon steel can be divided into two categories: general oriented silicon steel and high magnetic induction oriented silicon steel. It is mostly used in the field of electric energy transmission (such as transformers, etc.), and is an indispensable important metal functional material for electric power, electronics and military industries. Oriented silicon steel is known as steel artwork, with high technical content and complex process. Whether or not to master the production technology of oriented silicon steel is often used to measure the technical strength of a steel company. Its production...

Problems solved by technology

However, there are the following problems: 1) There is no clear standard for tooth loss and broken teeth, and different people have inconsistent judgment standards; 2) There is no clear standard for the length of sutured teeth. If it is too long, the two rows of suturing teeth will easily affect each other and cause disengagement; 3) There is no standard for the amount of overlap between the head and tail. 4) There is no standard for the unilateral width deviation of the front and rear two rolls. If the unilateral width deviation is too large, it will easily cause uneven force on the camber and easy to pull apart; Heavy sewing, slow down and shutdown, or even broken belts will affect the output of the unit
