Abstract

The invention provides an anti-wear bucket tooth for an excavator and a production process thereof, and relates to the technical field of bucket tooth production. The anti-wear bucket tooth comprisesthe following components in percentage by mass: 1.0-2.0 wt % of C, 12.0-20.0 wt % of Cr, 1.0-2.0 wt % of Ni, 0.5-1.5 wt % of Mn, 0.8-1.2 wt % of Si, 0.3-0.4 wt % of Ti, 0.2-1.0 wt % of Zr, 0.1-0.2 wt% of Re, 0.05-0.1 wt % of B, 0.2-0.3 wt % of Y, 0.1-0.3 wt % of W, 0.05-0.1 wt % of Nb, 0.06-0.10 wt % of P, 0.02-0.06 wt % of S, 2.0-3.0 wt % of a coupling agent, 1.6-2.0 wt % of a defoaming agent, 2.2-2.6 wt % of a flexibilizer and the balance of Fe and impurities. According to the invention, a plurality of wear-resistant components are adopted as bucket tooth fillers, and are reasonably proportioned, so that the components cooperate with each other, and the mechanical property of the bucket tooth is remarkably improved, and meanwhile, the prepared bucket tooth prepared through additive addition, heat treatment and the like is high in toughness, high in hardness, high in tensile strength, high in wear resistance and corrosion resistance, and is convenient to use and excellent in performance.

Description

technical field [0001] The invention relates to the technical field of bucket tooth production, in particular to an anti-wear bucket tooth for an excavator and a production process thereof. Background technique [0002] Excavator bucket teeth are important consumable parts on excavators. Similar to human teeth, they are combined bucket teeth composed of tooth seats and tooth tips, and the two are connected by pins. Bucket teeth are one of the main wear parts of the excavator. During the operation, they are directly in contact with sand, soil, rocks, minerals, etc. The working conditions are harsh, the wear is serious, and the consumption is large. The traditional bucket teeth are made of high manganese steel, but they have the disadvantages of short service life, poor wear resistance, and high friction and wear under high-frequency impact loads. [0003] At present, the formula composition and production process of bucket teeth are unreasonable, resulting in poor wear resis...
