The preparation method of a kind of automotive axle, is prepared by the steps:
(1) each raw material of following parts by weight is weighed respectively: carbon 5-9 part, manganese 4-7 part, nickel 2-5 part, ferrum 9-11 part, crystallization
Silicon 8-10 part, carbon fiber 2-6 part, calcium silicide 5-8 part, zirconium oxide 3-7 part, titanium dioxide 6-9 part and clay 3-5 part；
(2) raw material step (1) weighed obtains strand after smelting；
(3) strand is put into heating furnace to heat；
(4) strand after heating is put into milling train to roll, it is thus achieved that hot rolled plate；
(5) hot rolled plate is cooled down；
(6) hot rolled plate after cooling is batched, it is thus achieved that steel plate finished product.
Further, described strand is put into heating furnace and heats, including: described strand is heated in described heating furnace
To 1500-2000 DEG C；
Described strand is incubated after being heated to design temperature, and described temperature retention time controls as more than 200min.
Further, the described strand after heating is put into milling train and rolls, including: described strand is carried out roughing；Institute
Stating and carry out finish rolling after roughing completes, the inlet temperature of described finishing stands controls as 800-900 DEG C, and finishing temperature control is 700-
