Abstract

The present invention relates to an aluminum bronze alloy and a preparation method thereof. The aluminum bronze alloy comprises the ingredients by weight percentage: 75 to 82 wt% of Cu, 13 to 16 wt% of Al, 0.8 to 2.5 wt% of Mn, 2.5 to 5.0 wt% of Fe, 0.2 to 2.0 wt% of Co, 0.4 to 2.0 wt% of Ni, 0.4 to 1.2 wt% of Zn, 0.2 to 2.5 wt% of Re and at most 1.0 wt% of impurities. In the preparation method of the present invention, materials are mixed according to the ingredients; the mixed raw materials are loaded in an electric furnace to be melted in atmospheric ambience; the melted raw materials are sent in inert gas to be pre-refined; temperature is kept when reaching 1250 DEG C. The raw materials are chemically refined and are added with pure rare earth to be finally deoxidized; a covering agent is added after gas content is checked to be qualified; temperature is kept for 3 to 5 minutes when reaching 1260 DEG C; the materials are poured between 1160 and 1200 DEG C.

Description

Aluminum-bronze alloy and its preparation method

Technical field

The present invention relates to Alloy And Preparation Method.

Background technology

At present, the mould that is used for some mirror face stainless steel plates of machining large plate-type heat exchanger sheet, kitchen tool, household electrical appliance goods and titanium steel plate etc. generally adopts steel alloy manufacturings such as Cr12, Cr12MoV, T10A, Cr15, Cr-Ni.Tendency is serious because iron is adhered mutually, stretching, sticking to mould easily taking place during calendering stainless steel blank, scratching phenomenons such as workpiece, the product surface slide mark, scratching heavylier, needing follow-up polishing process to come workpiece is carried out surface treatment, the mould loss is serious, and the number of times that repairs a die is more.

Summary of the invention

The objective of the invention is to reduce slide mark, scuffing in stainless steel and the titanium steel minute surface plate work piece production process, improve the ratio of first-grade products of product, reduce the mould loss, enhance productivity.

McGill metals is measured its composition by weight percentage and is: Cu75~82%, Al13~16%, Mn0.8~2.5%, Fe2.5~5.0%, Co0.2~2.0%, Ni0.4~2.0%, Zn0.4~1.2%, rare earth 0.2~2.5%, impurity≤1.0%;

The preparation method of above-mentioned McGill metals is: by above-mentioned Cu75~82%, Al13~16%, Mn0.8~2.5%, Fe2.5~5.0%, Co0.2~2.0%, Ni0.4~2.0%, Zn0.4~1.2%, the composition of impurity≤1.0% is prepared burden, and the starting material that prepare is packed into melt in air atmosphere in the electric furnace, stay a spot of aluminium as pre-deoxidant, molten clear back air blowing preliminary refining adds pre-deoxidant and carries out deoxidation in advance, 1250 ℃ of insulation, carry out chemical refining and add 0.2~2.5% pure rare earth carrying out final deoxygenation, slagging-off, air content added insulating covering agent after the assay was approved, 1260 ℃ of insulations 3~5 minutes, the Ex-all bits are poured into a mould between 1160~1200 ℃.

Beneficial effect of the present invention is: aluminium in its composition and iron can improve hardness, the wear resistance of alloy material, add the aluminium of excessive (surpassing solid solubility), iron can generate hard in alloy K phase particle in the copper base alloy, the refinement alloy grain improves hardness of alloy and wear-resisting, anti-attrition performance.Add pure rare earth and can purify alloy, crystal grain thinning, reinforcement steel aluminium sosoloid, improved the wear-resisting and corrosion resistance nature of alloy, and deoxidation and deslagging ability are arranged.Nickel and brill are the effective solution strengthening element of copper base alloy, have improved the obdurability of alloy effectively.Alloy because component segregation is serious, needs can make its performance satisfy processing and mould service requirements after the solid-solution and aging heat treatment when as cast condition.Invention is used for some the mirror face stainless steel plates of machining large plate-type heat exchanger sheet, kitchen tool, household electrical appliance goods and the mould of titanium steel plate, give full play to its thermal conductivity good, good, good wear-resisting, anti-attrition and corrosion resistance nature and meticulous advantages such as texture structure with the block resistance of stainless material, product surface quality reaches requirement, can save the follow-up polishing process of product, the product breakage rate is an exogenous wind.The mould loss is few, produces 20000 and repairs a die once.

Embodiment

High-strength wear-resistance aluminum alloy alloy of the present invention is measured its composition by weight percentage and is: Cu75~82%, Al13~16%, Mn0.8~2.5%, Fe2.5~5.0%, Co0.2~2.0%, Ni0.4~2.0%, Zn0.4~1.2%, rare earth 0.2~2.5%, impurity≤1.0%;

Prepare burden by above-mentioned alloying constituent, with the starting material pure electrolytic copper plate for preparing, electrolytic aluminum, electrolytic nickel, electrolytic manganese, electrolytic zinc, iron (select for use smooth finish deoil preferably iron wire or iron nail), in air atmosphere, melt (staying a spot of aluminium) in the disposable middle frequency furnace of packing into such as electrolytic cobalt as pre-deoxidant, be blown into rare gas element preliminary refining such as nitrogen after melting clearly, add the pre-deoxidant pre-deoxidation, 1250 ℃ of insulations, carry out chemical refining and add 0.2~2.5% pure rare earth carrying out final deoxygenation, carry out chemical refining, add rare earth then and carry out final deoxygenation, rake is bits to the greatest extent, air content adds the insulating covering agent insulation after the assay was approved, 1260 ℃ left standstill 3~5 minutes, scratched clean bits, poured into a mould between 1160~1200 ℃.

Foundry goods can directly use as mould after the processing through solid-solution and aging heat treatment.
