17、 has been prepared by Technical Committee ECISS/TC 24 “Electrical steel sheet and strip qualities - Qualities, dimensions, tolerances and specific tests”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an ide

18、ntical text or by endorsement, at the latest by November 2006, and conflicting national standards shall be withdrawn at the latest by November 2006. This document supersedes EN 10126:1995 and EN 10165:1995. This document is based on IEC 60404-8-3:2005 which was technically changed. According to the

19、CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembou

20、rg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 10341:20064 Introduction This document has been prepared by merging EN 10126:1995 and EN 10165:1995, taking into consideration corresponding decisions of IEC/TC 68 on rele

21、vant IEC documents IEC 60404-8-2:1998 and IEC 60404-8 -3:1998 which are being merged at the same time. The merged document published as IEC 60404-8-3:2005 was the basis of this European Standard. The intention of this merging was to specify no longer non-alloy and alloy steel grades for cold rolled

22、electrical steel sheet and strip, but to leave the type of steel open. Therefore, it has been decided to use a new letter “K“ instead of previous used “D“ or “E“ for the designation of electrical steels specified in this European Standard. The dew point of the gas used for the heat treatment specifi

23、ed in 7.1.1 is + 20 C 2 C at atmospheric pressure. This is the value stated in EN 10165:1995 but it differs from the temperature of + 35 C stated in EN 10126:1995. As the final annealing of cold-rolled electrical non-alloy and alloy steel sheet and strip delivered in the semi-processed state is the

24、responsibility of the purchaser, attention is drawn to the importance of this treatment for the properties of the material. For this reason the magnetic properties in Table 1 are given for a reference condition (see 7.1.1) obtained by a suitable heat treatment. To ensure that the properties in use a

25、re equivalent to those specified, it is important that the heat treatment carried out by the user is equivalent to that used to define the reference condition. It is recognized that these materials may be used in the semi-processed state, in which case the magnetic properties are not subject to the

26、specifications of this standard. EN 10341:20065 1 Scope This document specifies cold-rolled electrical non-oriented non-alloy1)or alloy2)steel sheet and strip delivered in nominal thicknesses of 0,50 mm and 0,65 mm in the semi-processed condition, that is without final heat treatment; in particular,

27、 it specifies general requirements, magnetic properties, geometric characteristics and tolerances and technological characteristics, as well as the inspection procedure. This document applies to material intended for the construction of magnetic circuits. These magnetic materials correspond respecti

28、vely to subclauses C21 and B2 of IEC 60404-1:2000. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including

In addition, the fol

33、lowing terms and definitions apply. 1) Non-alloy steel is that steel the basic constituent of which is iron containing alloying elements in amounts smaller than the limiting values fixed by EN 10020. 2) Alloy steel is that steel the basic constituent of which is iron containing alloying elements in

34、amounts equal to or greater than the limiting values fixed by EN 10020.

36、 Classification and designation 4.1 Classification The steel grades covered by this document are classified according to the specified value of maximum specific total loss in watts per kilogram at 1,5 T after a reference heat treatment (see 7.1.1) and according to the nominal thickness of the materi

37、al (0,50 mm, 0,65 mm). 4.2 Designation 4.2.1 For the steel grades covered by this document, the steel names are allocated in accordance with EN 10027-1. The steel numbers are allocated in accordance with EN 10027-2. The steel name comprises the following in the order given: 1) the letter M for elect

38、rical steel; 2) one hundred times the specified value of maximum specific total loss at 50 Hz, in watts per kilogram, corresponding to the nominal product thickness, at 1,5 T; 3) one hundred times the nominal thickness of the material, in millimetres; 4) the letter K for non-alloy or alloy electrica

EN 10341:20068 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 bundles in the case of sheets and

46、in coils in the case of strip. The mass of bundles of sheets or coils shall be agreed at the time of enquiry and order. The most usual values for internal diameter of coils are approximately 508 mm and 610 mm. The recommended value is approximately 508 mm. The external diameter shall be the subject

47、of an agreement at the time of enquiry and order. Sheets which make up each bundle shall be stacked so that the side faces are substantially flat and approximately perpendicular to the top face. Strip shall be of constant width and wound in such a manner that the edges are superimposed in a regular

48、manner and that the side faces of the coil are substantially flat. Coils shall be sufficiently tightly wound 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 and order. If necessary, the marking o

49、f welds may be agreed at the time of enquiry and order. For coils containing repair 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. 6.3 Delivery condition Material supplied with trimmed edges shall not have any burrs which will adversely affect its further application or use. As the result of the method of manufacture and delivery in the form of coils, material may, in the delivery condition, exhibit residual
