镶铸法加消失模铸造制备破碎机锤头工艺研究
Research on the Process of Preparing Crusher Hammer Heads by Inlay Casting and Expendable Pattern Casting
摘要
Abstract
To further improve the service life of a crusher and reduce its production cost,a crusher hammer head was prepared via the inlay casting method and lost foam casting technology,and microstructure,microstructure,hardness and other tests were carried out on inlay casting samples.The morphology and structural characteristics of the inlay casting interface were studied,and the influence of water toughening treatment on the hardness change of the hammer head was discussed.As a result,the composite hammer head after water toughening treatment has no pores or sand stuck to its surface.There is mutual diffusion of elements such as Mn and Ti between the ZGMn13 matrix and the embedded column,resulting in good metallurgical bonding.The Rockwell hardness from the substrate to the embedded column increases from 24.9 HRC to 60.8 HRC,which meets the production and usage requirements.关键词
