长垣市垣起中龙起重机械有限公司专业生产车轮组质量保障

车轮是用来支承起重机和载荷，并在轨道上使起重机往复行驶运行的装置。车轮主要损伤的形式是磨损、硬化层压碎和点蚀。车轮的材料一般采用ZG430-640铸钢。为了提高车轮表面的耐磨强度和寿命，踏面应进行表面热处理，要求表面硬度为HB300-350，淬火深度不少于20mm。Changyuan city Yuanqi Zhonglong Crane Machinery Co. , Ltd. is specialized in the production of Wheel Group Quality Assurance, wheel is used to support the crane and load, and on the track to make the crane reciprocating running device. The main forms of wheel damage are wear, crush of hardened layer and pitting. The wheel is usually made of ZG430-640 cast steel. In order to improve the wear resistance and service life of the wheel surface, the tread surface should be heat treated, the surface hardness should be HB300-350, the quenching depth should be not less than 20mm.
