Abstract
A method for manufacturing a laminated body includes: laminating an electromagnetic steel plate to form the laminated body; performing an annealing process on the laminated body; acquiring a before-annealing lamination thickness information on a thickness of the laminated body before performing the annealing process on the laminated body; and when the before-annealing lamination thickness information does not satisfy a before-annealing criterion which is predetermined, adjusting a lamination condition of the electromagnetic steel plate such that the before-annealing lamination thickness information satisfies the before-annealing criterion.
Claims9
A method for manufacturing a laminated body, comprising:
- repeatedly laminating electromagnetic steel plates to form a laminated body under a predetermined lamination condition;
- performing an annealing process on the laminated body;
- acquiring a before-annealing lamination thickness information on a thickness of the laminated body before performing the annealing process on the laminated body;
- and
- in an occurrence that the before-annealing lamination thickness information of the laminated body does not satisfy a before-annealing criterion which is predetermined, changing a lamination condition of a following laminated body formed subsequent to the laminated body such that a before-annealing lamination thickness information of the following laminated body satisfies the before-annealing criterion, wherein
- the before-annealing criterion that is predetermined is set in advance based on a relationship between before-annealing lamination thickness information and after-annealing lamination thickness information for previous laminated bodies that correspond to specified thicknesses of the previous laminated bodies before and after annealing that are acquired previously, and wherein
- the following laminated body is formed by repeatedly laminating electromagnetic steel plates of the following laminated body.

- wherein the before-annealing criterion includes a before-annealing pressed state criterion and a before-annealing no-load criterion which are predetermined, and
- wherein in an occurrence that at least one of a case where the before-annealing pressed state information of the laminated body does not satisfy the before-annealing pressed state criterion and a case where the before-annealing no-load state information of the laminated body does not satisfy a before-annealing no-load state criterion, the lamination condition of the following laminated body is changed such that the before-annealing pressed state information of the following laminated body and the before-annealing no-load state information of the following laminated body satisfy the before-annealing pressed state criterion and the before-annealing no-load state criterion, respectively.
