Optimal design of low carbon low alloy wear-resistant bucket tooth steel

The production process of low-alloy steel is relatively simple, the cost is not high, and its wear resistance and toughness are good, suitable for mechanical engineering fields such as excavator buckets. When the bucket is in direct contact with the material during excavation operations, it will cause serious wear and tear. In order to increase the strength and wear resistance of the bucket, and to improve the strength and wear resistance of the bucket, the chemical composition of the bucket tooth steel was improved, and the sprue and riser of the casting system were optimized and designed. The experimental results show that the wear amount of the newly designed bucket tooth side plate in the height direction is only 55.0%, 54.0%, and 57.1% of YNM400 steel, which is about half of the wear amount of YNM400 steel. The wear resistance has been significantly improved, and no phenomena such as detachment or cracking occurred during the testing process, which meets the weldability standards. The use of this new type of steel can improve the performance of excavators, which is of great significance for the development of the excavator industry.
