输送带用钢丝绳国家标准修订研究

Research on national standard of steel wire ropes for conveyer belts

介绍GB/T 12753—2008《输送带用钢丝绳》标准提出的背景和修订的内容:增加外层为8股的结构钢丝绳;6×19-WSC和6×19W-WSC结构钢丝绳直径调整为6~16 mm,其中心股的中心钢丝可以用1×3结构的钢丝股替代;钢丝的抗拉强度调整为2 060、2 160、2 260、2 360、2 460、2 560 MPa级别,取消1 960 MPa级别,增加2 560MPa级别;增加数值修约与检测数值的判定标准。并对新增结构钢丝绳进行了工艺技术验证。指出提高输送带用钢丝绳的经济性是标准修订的方向。该标准修订后达到国际先进水平,可以有条件转化为国际标准。

To introduce the background and revision items of GB / T 12753-2008 steel wire ropes for conveyer belts,to add the structure wire rope of outer 8 strands; wire rope diameter of 6 × 19-WSC and 6 × 19W-WSC structure is changed to6 ~ 16 mm,the tensile strength of steel wire is changed to 2 060、2 160、2 260、2 360、2 460、2 560 MPa grade,the 1 960 MPa grade is cancelled,2 560 MPa grade is added. The numerical value revised and detection value judge stipulation are added. And newly-added wire rope structure is technological validated. It is pointed out that improve the economic benefit of wire rope for conveyor belt is the direction of the standard revision. The revised standard reaches international advanced level,and can be conditionally converted into the international standard.
