镶铸法加消失模铸造制备破碎机锤头工艺研究OA
Research on the Process of Preparing Crusher Hammer Heads by Inlay Casting and Expendable Pattern Casting
为进一步提高破碎机使用寿命,降低生产成本,采用镶铸法+消失模铸造技术制备破碎机锤头,并对镶铸试样进行组织分析和微观形貌、硬度等检测,研究镶铸界面结合形态及结构特征,讨论了水韧处理对锤头硬度变化的影响.结果表明,经水韧处理后的复合锤头,其表面无孔洞、粘砂,ZGMn13基体与镶柱之间出现Mn、Ti等元素的相互扩散,形成了良好的冶金结合.从基体到镶柱,洛氏硬度由24.9 HRC提高到60.8 HRC,可以满足生产使用要求.
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.
