近年来选矿流程中细筛分级技术得到广泛地推广应用,为了提高筛分效率和筛网寿命,研制合适的筛网材料的问题逐渐引起人们的重视。目前,尼龙筛篦和金属筛网之间存在着竞争,虽然尼龙筛篦的使用寿命较长,但存在着有效筛分面积很小,筛孔尺寸容易变形等固有缺点。因此,对于那些要求较高的细筛说来,仍然需采用金属细筛网。据近年来对国外筛网样品的分析表明,美国、加拿大和日本等国的筛网都是由单相、无磁、主要成份为Fe-Cr-Ni的奥氏体
In recent years, beneficiation process fine sieve grading technology has been widely applied, in order to improve the screening efficiency and screen life expectancy, the development of suitable screening materials gradually attracted the attention of people. Currently, there is competition between nylon mesh and metal mesh. Although nylon mesh grate has a longer service life, it has inherent shortcomings of small effective mesh size and easy deformation of mesh size. Therefore, for those demanding fine sieve said, still need to use fine metal mesh. According to the analysis of overseas sieve samples in recent years, the sieves in the United States, Canada and Japan are all composed of single phase, non-magnetic austenite whose main component is Fe-Cr-Ni
