Abstract
The invention discloses a preparation process for a metal matrix material for a petroleum sleeve, and the preparation process solves the problem that a current alloy material cannot simultaneously meet cost requirements and strength requirements. The preparation process comprises the following steps: step I, adding pig iron into a furnace to melt as an iron substrate, and carrying out desulfuration treatment, deoxidization treatment and dephosphorization treatment on the iron susbtrate for enabling sulfur content to be lower than 0.02% and phosphor content to be lower than 0.03% in the pig iron; step II, adding Mn, Cu and N into the iron matrix to uniformly mix to obtain a mixture, heating the mixture to a molten state, keeping the molten-state mixture for 1-2 hours, then, adding Si, Cr and C into the mixture to uniformly mix, preserving the heat for at least two hours at a temperature being 800-1100 DEG C, rising the temperature to 1200-1250 DEG C with a temperature rising rate being 5-10 DEG C/min, preserving the heat for at least two hours, and carrying out constant-temperature casting at a temperature being 800-850 DEG C; step III, reducing the temperature and quickly cooling to a temperature lower than 200 DEG C after casting; and step IV, preserving the heat after cooling, and finally quenching and tempering to prepare a finished product. In case of guaranteeing low cost, high strength and high hardness are guaranteed, so that acid etching resistance can be effectively improved.
