22、-3:2012EN 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 other high duty applications. Heavy duty refers to
23、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 addition to the requirements of this part of this
24、 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 applications: dimensional tolerances; mechanical cha
25、racteristics; 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.

29、signation of the product The designation of wire for ropes manufactured in accordance with this European Standard shall be based on the nominal dimension, surface appearance and tensile strength. The indicator of dimension for round wire is the nominal diameter; for shaped wire it is the value of th
30、e 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 wire, with a letter indicating the class of coating (
31、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 2,0 - A 1 570 EXAMPLE 2 Wire for rope, trapezoidal pro
32、file, 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, tensile strength grade 1 370 MPa, in accordance with
33、 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 applications, and in accordance with EN ISO 16120-1 and EN ISO
34、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. The coatings commonly used are zinc or Zn95/Al5. Unles
35、s 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 used for the coating material (zinc or zinc alloy) shou
36、ld 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 Characteristics of the wire 5.1 Tensile strength grades The tensi
37、le 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. BS EN 10264-3:2012EN 10264-3:2012 (E) 6 Table 1 Tensile streng

40、re, 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 conventional characteristic values are as follows: h heigh
41、t: 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 the profile; e distance taken diagonally across the transve
42、rse 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) and that of a trapezoidal wire by the letter T followed by
43、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.

The diameter of the eq
45、uivalent 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
46、 planimetry on the drawing of the shaped wire. If the surface area of the transverse section of the shaped wire is A and the perimeter C, the equivalent values are calculated as follows: equivalent a = AA24= equivalent c = C5.3 Minimum requirements for wire characteristics 5.3.1 Dimension measured v
47、alues The measured values for the round wire shall satisfy the requirements of Table 3. Ovality shall not be greater than half the tolerance specified in Table 3.
