Description

technical field [0001] The invention belongs to the technical field of food processing machinery, and in particular relates to a wear-resistant food machinery material and a preparation method thereof. Background technique [0002] The mechanical properties of metal materials such as strength, hardness (wear resistance), plasticity and toughness usually show mutual restriction and mutual influence to form a contradictory unity. According to the actual use requirements of different industries and combined with existing processing methods and capabilities, selecting reasonable alloy components and contents to achieve optimal metal alloy materials has always been the direction of efforts in the material industry. [0003] In food processing, whether it is primary processing or finishing processing, there are usually processes such as crushing, crushing, and stirring of food. These processes require the use of corresponding mechanical equipment to drive tools of specific shapes ...
