Abstract

The invention discloses an aluminum alloy ingot for a tire bell with high tensile strength and a production process thereof, belonging to the field of aluminum alloy processing. Its components and the percentages of each component are: Mg1.2‑1.9%, Ni1.1‑1.7%, Si0.4‑1.6%, Fe0.4‑0.7%, Ti0.25‑0.44%, Y0.13‑0.27 %, Zn0.09‑0.25%, Gd0.08‑0.14%, Er0.06‑0.09%, Ce0.03‑0.08%, the total amount of impurity elements of other metals and nonmetals does not exceed 0.5%, and the rest is Al; The invented aluminum alloy ingot has good tensile performance and high toughness at high temperature, and appropriate addition of rare earth elements Gd, Y, Er, and Ce can increase the heat dissipation, strength and durability of the tire bell. The aluminum alloy ingot is prepared through melting-refining-standstill-casting-annealing and other process steps; through the production process of the present invention, the casting structure of the aluminum alloy ingot is uniform and is not easy to oxidize, which greatly improves the use of aluminum alloy tire bells This technology has a broad market prospect in the popularization of aluminum alloy tire bells.

Description

technical field [0001] The invention relates to the field of aluminum alloy processing, in particular to an aluminum alloy ingot for a tire bell with high tensile strength and a production process thereof. Background technique [0002] The tire bell is an important component of the wheel. The tire bell is often used under complex and harsh conditions. It is subjected to various deformations and loads when driving, so it must have high load-carrying and mechanical properties. Existing The existing tire bell has disadvantages such as poor heat dissipation, poor toughness, and poor durability, which is not conducive to the safe and comfortable driving of the car. The requirements for wheels lie in high precision in size and shape, light weight, good dynamic balance, high fatigue strength, and aesthetics. Tire bells, as one of the important components in the driving system of automobiles, are also a kind of security parts with high requirements. It not only carries the weight o...
