本文的“圆锥破碎机衬板”系指高锰钢铸造的破碎壁、轧臼壁或是动锥衬板、定锥衬板。金属铸件的残存内应力往往是圆锥破碎机衬板的致命杀手。由于圆锥破碎机的工矿条件,决定了圆锥衬板的表面必须要承受很高的径向挤压力和周向剪切力,圆锥衬板的残存内应力会很快导致圆锥衬板过早地开裂报废,严重影响生产的正常进行。目前德兴铜矿目处理矿石达到10万t以上,不仅对圆锥衬板的需求量大,而且对圆锥衬板的质量也提出了非常高的要求。对生产供应商来说,既是机遇,更是挑战。一些英勇善战的生产供应商在“时效”面前遭受重创,悲壮地退出“战场”。下面为读者娓娓道来该矿圆锥破碎机衬板的“时效”故事,以供诸位悉心品味。
This article “cone crusher lining” refers to the high manganese steel casting broken wall, rolling acetabular wall or moving cone liner, fixed cone liner. Residual internal stress of metal castings are often fatal killers of cone crusher linings. Due to the industrial conditions of the cone crusher, it is determined that the surface of the cone liner must withstand high radial compressive force and circumferential shear force. The residual internal stress of the cone liner will quickly cause the cone liner to prematurely Cracking scrap, seriously affecting the normal production. At present, Dexing copper mine processing ore reached 100,000 tons or more, not only the demand for the cone liner, but also the quality of the cone liner also put forward very high requirements. For production suppliers, it is both an opportunity and a challenge. Some brave and fierce production suppliers have suffered heavy losses in the face of aging and tragically withdraw from the battlefield. The following for the reader explain the mine cone crusher liner “aging ” story, for you to taste.
