Embodiment Construction

[0014] A production process of high wear-resistant aluminum alloy profile includes the following steps:

[0015] (1) Put the charge into the smelting furnace for heating and smelting. After the charge is melted, sprinkle 3 / 5 amount of covering agent to cover. When the alloy melt is heated to 765°C, use 0.3% NaBF of the charge weight 4 And 0.5% C 2 Cl 6 For refining, put it in the furnace and let it stand for 15 minutes. When the temperature is lowered to 730℃, press the block modifier into the bottom of the furnace for metamorphism treatment. After the metamorphism reaction for 2 minutes, sprinkle the remaining 2 / 5 of the covering agent and let it stand for 14 minutes It can be cast. Before casting, ensure that the mass percentage of each alloy element in the melt is: Si 12-16, Mg 4-6, Zn 2-3, Mn 0.6-1.2, V 0.4-0.8, Cr 0.3-0.5 , Ni 0.2-0.3, Ti 0.18-0.22, Co 0.1-0.15, As 0.03-0.05, In 0.02-0.03, P 0.01-0.02, RE 0.08-0.12, the balance is Al;

Abstract

The invention discloses a production technique of a high-wear-resistance aluminum alloy section. The alloy comprises the following elements in percentage by mass: 12-16% of Si, 4-6% of Mg, 2-3% of Zn, 0.6-1.2% of Mn, 0.4-0.8% of V, 0.3-0.5% of Cr, 0.2-0.3% of Ni, 0.18-0.22% of Ti, 0.1-0.15% of Co, 0.03-0.05% of As, 0.02-0.03% of In, 0.01-0.02% of P, 0.08-0.12% of RE and the balance of Al. By properly enhancing the Mg element content and optimizing the Si / Mg ratio, abundant Mg2Si phases can be generated in the alloy structure, and the hard granules can obviously enhance the wear resistance of the alloy; and small amounts of As, In and RE added into the alloy structure can improve the high-temperature stability of the alloy. The aluminum alloy section has the advantages of high strength, strong high-temperature stability and excellent wear resistance, and can be widely used in industrial wear-resistant parts.

Description

Technical field [0001] The invention relates to a production process of high wear-resistant aluminum alloy profiles, and belongs to the technical field of aluminum alloy materials.
