Abstract

The invention discloses a raw material formula for adjustment arm shell castings of an automobile brake. The raw material formula comprises the following components by weight: 100-130 parts of pig iron, 50-90 parts of carbon steel, 3-8 parts of tungsten steel, 20-40 parts of titanium steel, 6-10 parts of manganese, 15-20 parts of chromium, 12-18 parts of nickel, 5-15 parts of copper powder, 5-15 parts of magnesium powder, 4-12 parts of aluminium powder and 1-5 parts of titanium powder. A production process for the raw material formula for the adjustment arm shell castings of the automobile brake comprises the following steps: S1. raw material cleaning and drying; S2. powder mixing; S3. primary heating; S4. primary mixing; S5. powder fusion; and S6. cooling forming. The formula and the production process, which are disclosed by the invention, are simple, capable of reducing the energy consumption needed for production and the production cost, capable of increasing the strengths of the products through the addition of manganese and chromium, capable of improving the elasticity of the products through the addition of the titanium powder, and capable of increasing the hardness of the products through the addition of the tungsten steel; therefore, the products produced by the scheme disclosed by the invention have better quality and higher market competitiveness.

Description

technical field [0001] The invention relates to the field of casting raw material production, in particular to a raw material formula and a production process for an automobile brake adjusting arm casing casting. Background technique [0002] The existing raw materials used for the production of castings of automobile brake adjusting arm shells have unreasonable formulas, resulting in products with low strength, poor wear resistance, and poor elasticity. Therefore, the automobile brake adjusting arms produced using traditional processes and formulas The quality of the shell castings is not good, and in the prior art, the production process is complicated, so the energy consumption is high, and the production cost is too high, which not only does not meet the current social theme of energy conservation and environmental protection, but also has poor market competitiveness. Contents of the invention [0003] The object of the present invention is to provide a raw material fo...
