锤片是锤片式粉碎机的主要工作部件,极易磨损。据文献介绍,我国粉碎机锤片每年耗用钢材达5万t以上。随着养殖业与饲料工业的发展,锤片耗量还将继续增大。如何提高锤片的耐磨性,减少钢材消耗,提高粉碎机的生产效率,降低饲料加工成本的问题,越来越受到人们的重视,渗硼是一种表面强化工艺,可显著提高工件的耐磨性。为此,我们对粉碎机锤片进行了渗硼试验。一、试验材料与方法试验采用目前粉碎机锤片常用的20钢和QT600-2球铁,以及GP-2型粒状渗硼剂。将上 Hammer is the main working part of the hammer mill, easy to wear. According to the literature, China’s crusher hammer consumes more than 50,000 t of steel annually. With the development of aquaculture and feed industry, hammer consumption will continue to increase. How to improve the wear resistance of the hammer, reduce the consumption of steel, improve the mill’s production efficiency and reduce the cost of feed processing, more and more people’s attention, boronizing is a surface strengthening process, can significantly improve the resistance of the workpiece Grindability. For this reason, we have carried on the boronizing test to the crusher hammer piece. First, the test materials and methods The test is currently used by the mill hammer 20 steel and QT600-2 ductile iron, and GP-2 granular boronizing agent. Will be on
