Abstract

The invention discloses a stable and reliable automobile balancing block and a production process thereof. The automobile balancing block is prepared from the following elements according to percentage by mass: 10-30% of manganese, 0.05-0.25% of thallium, 0.2-1.5% of chromium, 0.5-1.5% of silicon, 0.02-0.8% of nickel, less than or equal to 0.08% of sulfur, 0.02-0.15% of niobium, 0.5-2.5% of carbon and the balance of iron and inevitable impurities. The production process of the stable and reliable automobile balancing block comprises the following steps: adding iron into a resistance furnace; removing oxidization slag on the surface of melt after the iron is completely molten; cooling, adding preheated silicon, nickel, sulfur and niobium, and preserving heat; then adding preheated manganese, thallium, chromium and carbon, preserving heat and removing dross; refining, standing, casting and molding and carrying out ageing treatment to obtain the balancing block. The balancing block is low in cost, high in product surface quality, free of magnetism, low in deformation, excellent in product surface consistency, high in density, strong in applicability, long in service life and wide in market prospect, is stable and reliable; the performance of the balancing block is not changed at 800 DEG C.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a stable and reliable automobile balance weight and a production process thereof. Background technique [0002] Balance weight, also known as tire balance weight. It is a counterweight component installed on the wheel of the vehicle. The function of the balance weight is to keep the wheel in dynamic balance under high-speed rotation. The function of the balance weight is to minimize the quality gap of the wheels to achieve a relatively balanced state. The balance weight is required to be non-magnetic and non-magnetized. If it is magnetic, the rotor will be affected by the Loren magnetic force when it rotates at high speed in a changing magnetic field, causing the rotor of the motor to be unbalanced, thereby affecting the operating efficiency and life of the motor. . In addition to requiring no magnetism, the balance weight is also required to have accurate weight. Existin...
