DIN EN 10264-3:2012-03 EN 10264-3:2012 (E) 4 1 Scope This part of this European Standard specifies round and shaped non alloyed steel wire for use in the manufacture of ropes for mine hoisting, man-riding haulage, cableways for the transportation of passengers and ot

26、her high duty applications. Heavy duty refers to situations where the stresses applied to the rope are either high or vary by a large amount during service. This part of this European Standard refers to round wires and three types of shaped wire: full lock (Z), half lock (H) and trapezoidal (T). In

27、addition to the requirements of this part of this European Standard, the requirements of EN 10264-1 also apply. It does not apply to steel wire taken from manufactured ropes. This part of this European Standard specifies the following for cold drawn non alloyed steel wire for ropes for high duty app

28、lications: dimensional tolerances; mechanical characteristics; requirements relating to the chemical composition of the steel wire; conditions to be satisfied by any coating. 2 Normative references The following referenced documents are indispensable for the application of this document.

The indicator of dimension for round wire is the n

33、ominal diameter; for shaped wire it is the value of the height (h), followed by a letter specifying the profile. In the case of H profiles, this indicator shall be followed by the value of the narrowing. The surface appearance shall be indicated as defined in EN 10264-1 with U for uncoated or bright

34、 wire, with a letter indicating the class of coating (A, B, ) and in the case of zinc alloy coatings, indicating in brackets (Zn/Al). EXAMPLE 1 2,0 mm wire for rope with thick zinc layer, class A, tensile strength grade 1 570 MPa, in accordance with EN 10264-3. Designation: wire for rope EN 10264-3

35、2,0 - A 1 570 EXAMPLE 2 Wire for rope, trapezoidal profile, h = 3,5 mm, class B zinc coated, tensile strength grade 1 770 MPa, in accordance with EN 10264-3. Designation: wire for rope EN 10264-3 - T3,5 - B 1 770 EXAMPLE 3 H shaped wire for rope h = 3,0 mm, w = 1,8 mm, coated with class A zinc alloy

36、, tensile strength grade 1 370 MPa, in accordance with EN 10264-3. Designation: wire for rope EN 10264-3 - H 3,0 1,8 - A (Zn/Al) 1 370 4 General conditions of manufacture The drawn wire shall be manufactured from rod in accordance with EN ISO 16120-1 and EN ISO 16120-2 for ropes for static applicati

37、ons, and in accordance with EN ISO 16120-1 and EN ISO 16120-4 for ropes for dynamic applications. The drawn wire shall show no surface defects or internal defects prejudicial to its use. When specified, the drawn wire shall be supplied with a coating applied by a hot dipping or electrolytic method.

38、The coatings commonly used are zinc or Zn95/Al5. Unless otherwise specified, the zinc used for coating shall have a purity of 99,95 % according to EN 1179, Z3, other zinc alloys may be agreed at the time of enquiry and order. NOTE If required by the purchaser, the quality of the zinc or zinc alloy u

39、sed for the coating material (zinc or zinc alloy) should be certified by the manufacturer. Because of the reaction between the base material and coating material, which is inherent to the process, the composition of the coating on the wire is different to that used in the coating bath. 5 Characteris

40、tics of the wire 5.1 Tensile strength grades The tensile strength grades are defined in Table 1. NOTE The nominal values are the minimum tensile strength limits. The upper limits (maximum) are equal to these minimum values increased with the tolerances specified in EN 10264-1:2011, Table 1. DIN EN 1

43、 5.2 Profiles 5.2.1 Definition of shaped wire For shaped wire, the characteristic sections of the wire are shown in Figure 1 for full lock Z, half lock H and trapezoidal T wires. The nominal dimensions and tolerances shall be agreed between the supplier and the purchaser at the time of ordering. The

44、 conventional characteristic values are as follows: h height: difference between the radii of the 2 concentric boundary circles; b width: maximum width of upper part perpendicular to a radial line passing through the centre of the width (as shown in Figure 1); w minimum narrowing: smallest width of

45、the profile; e distance taken diagonally across the transverse section of the profile (essentially T or Z profiles). The designation of a full lock wire is established using the letter Z and the height (h), that of a half lock wire by H followed by the height (h) and the minimum narrowing (w) (h w)

46、and that of a trapezoidal wire by the letter T followed by the height (h). Table 2 gives the design criteria for the shaped wire shown in Figure 1. These are the relation between the height of the shaped wires and the other major characteristic dimensions. DIN EN 10264-3:2012-03 EN 10264-3:2012 (E)

48、ivalent diameter of shaped wire is as follows. The diameter of the equivalent transverse circular section (a) is the diameter of a circle with the same transverse section surface area as the shaped wire. The diameter of the equivalent circular circumference (c) is the diameter of the circle with the same perimeter as the shaped wire. Nominal values may be measured by planimetry on the drawing of the shap
