25、 10107:2014 (E) 4 1 Scope This European Standard defines the steel grades of grain-oriented electrical strip and sheet in nominal thicknesses of 0,23 mm, 0,27 mm, 0,30 mm and 0,35 mm and specifies in particular, general requirements, magnetic properties, geometric characteristics and tolerances and

26、technological characteristics, as well as inspection procedures. This European Standard applies to Goss textured grain-oriented electrical strip and sheet supplied in the final annealed condition in sheets or coils, and intended for the construction of magnetic circuits. The materials are grouped in

27、to two classes: a) conventional grain oriented material; b) high permeability grain oriented material. They correspond to Clause C.22 of IEC 60404-1:2000. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its ap

37、in relation to the line of cutting 4 Classification and designation 4.1 Classification The steel grades covered by this European Standard are classified according to the value of maximum specific total loss in watts per kilogram and according to the nominal thickness of the material (0,23 mm; 0,27 m

38、m; 0,30 mm; 0,35 mm). 4.2 Designation 4.2.1 For the steel grades covered by this European Standard, the steel names are allocated in accordance with EN 10027-1.

DIN EN 10107:2014-07EN 10107:2014 (E) 7 6 General requirements 6.1 Production process The production process of the steel and its chemical composition are left to the discretion of the manufacturer. 6.2 Form of supply The material is supplied in coils

47、 in the case of strip and bundles in the case of sheets. The mass of coils or bundles of sheets shall be agreed at the time of enquiry and order. The recommended value for the internal diameter of coils is approximately 508 mm. Strip shall be of constant width and wound in such a manner that the edg

48、es are superimposed in a regular manner and that the side faces of the coil are substantially flat. Coils shall be sufficiently tightly wound so that they do not collapse under their own weight. Strip may exhibit welds resulting from the removal of defective zones if agreed at the time of enquiry an

49、d order. If necessary the marking of welds may be agreed at the time of enquiry and order. For coils containing welds, each part of the strip shall be of the same grade. The edges of parts welded together shall not be so much out of alignment as to affect the further processing of the material. Sheets which make up each bundle shall be stacked so that the side faces are substantially flat and approximately perpendicular to the top face. 6.3 Del
