Problems solved by technology
The invention discloses a high-strength automobile steering knuckle and a preparation method thereof. The preparation method is characterized in that pig iron, silicon carbide particles, graphite fiber, manganese, nickel, chromium, ceria and titanium oxide are mixed and then are smelted; then refining is carried out and thus molten iron is obtained, and the molten iron is subjected to casting moulding subsequently and thus a moulded blank is obtained; finally the moulded blank is subjected to heat treatment and thus the high-strength automobile steering knuckle is prepared; and with respect to 100 parts by weight of pig iron, the use amount of silicon carbide is 0.5-0.8 part by weight, the use amount of graphite fiber is 1.5-2.5 parts by weight, the use amount of manganese is 0.6-1.5 parts by weight, the use amount of nickel is 0.1-0.5 part by weight, the use amount of chromium is 0.3-0.6 part by weight, the use amount of ceria is 0.1-0.5 part by weight, and the use amount of titanium oxide is 0.05-0.1 part by weight. The high-strength automobile steering knuckle has the advantages of high tensile strength, high yield strength, high elongation percentage, good shock resistance and the like.
