Problems solved by technology

[0005] a) Poor wear resistance and short service life;
[0006] b) Poor high temperature resistance;
[0007] c) Fast heat conduction, easy to deform
[0008] Patent No. "200410051611.5" and invention title "A Car Brake Disc and Its Manufacturing Method" discloses a brake disc and its manufacturing method, wherein the material of the brake disc is silicon nitride ceramic material, which has high durability Wear resistance and high temperature resistance, but this kind of brake disc is brittle and easy to break. Once damaged, it cannot be repaired, and the manufacturing process is completely different from the original brake disc. The manufacture of this brake disc requires the replacement of the original casting equipment, so The investment is large, and the scope of use is limited

Embodiment 1

[0043] Example 1: A method for manufacturing automobile brake discs. First select 992 kg of gray cast iron G3000 and 8 kg of ceramic fiber, and then put 992 kg of gray cast iron G3000 in an electric furnace to be heated to melt, continue to heat to form molten iron, and remove Waste residue, after the temperature reaches 1400°C, add 8 kg of ceramic fibers to the molten iron, continue to heat, increase the temperature to 1450°C, stir evenly, cast into the sand mold cavity, cool and shape, and finally obtain the product obtained by the present invention Moving disc or brake hub.

Embodiment 2

[0044] Example 2: A method for manufacturing automobile brake discs. First select 994 kg of gray cast iron G3000 and 6 kg of ceramic fiber, and then put 994 kg of gray cast iron G3000 in an electric furnace and heat it to melt, continue to heat to form molten iron, and remove Waste residue, after the temperature reaches 1400°C, add 6 kg of ceramic fiber to the molten iron, continue to heat, increase the temperature to 1420°C, stir evenly, cast into the sand mold cavity, cool to shape, and finally obtain the product obtained by the present invention Moving disc or brake hub.

Embodiment 3

[0045] Example 3: A method for manufacturing automobile brake discs. Firstly, 991 kg of gray cast iron G3000 and 9 kg of ceramic powder are selected, and then 991 kg of gray cast iron G3000 is heated in an electric furnace to melt, and continue to be heated to form molten iron. Waste residue, after the temperature reaches 1400°C, add 9 kg of ceramic fiber to the molten iron, continue to heat, increase the temperature to 1480°C, stir evenly, cast into the sand mold cavity, cool and shape, and finally obtain the product obtained by the present invention Moving disc or brake hub.

Abstract

The invention discloses a manufacturing method for an automobile brake disc or brake hub. The manufacturing method includes the steps of distributing, melting, slag removal, casting, cooling forming and the like. Ceramic powder or ceramic fiber is added into molten iron after slag removal, and the molten iron is uniformly stirred after continuing to be heated until the ceramic powder or ceramic fiber is melted. The brake disc or brake hub manufactured by adding a proper amount of the ceramic fiber or ceramic powder has the advantages of weak heat conductivity, low heat transfer capacity and the like. When instant temperature is generated in brake, heat cannot be immediately transferred to the whole brake disc or brake hub, and the temperature of other positions of the brake disc or brake hub is low, so that the friction coefficient of the surface of the brake disc or brake hub cannot be decreased, and brake effects cannot be reduced or lost. Therefore, the technical scheme requiring protection has outstanding substantial advantages and remarkable progress.

Description

Technical field [0001] The invention relates to a manufacturing method, in particular, to a manufacturing method of an automobile brake disc or brake hub. Background technique [0002] In the automobile brake system, the brake disc or brake hub is one of the most critical safety components. The quality of the brake disc and brake hub will directly affect the braking performance of the automobile brake assembly. The brake disc is composed of steel plate, adhesive heat insulation layer and friction block. The steel plate must be painted to prevent rust. The heat insulation layer is composed of materials that do not transfer heat for the purpose of heat insulation. The friction block is composed of friction material and adhesive, and is squeezed on the brake disc or brake hub to generate friction during braking, so as to achieve the purpose of decelerating and braking the vehicle. Due to friction, the friction block will gradually be worn out. The brake disc or brake hub should be ...
