Abstract

The invention discloses an aluminium bronze alloy and its preparing process with the constituents (by weight percentage) of, Cu75-82%, Al 13-16%, Mn 0.8-2.5%, Fe2.5-5.0%, Co 0.2-2.0%, Ni 0.4-2.0%, Zn 0.4-1.2%, Re 0.2-2.5%, impurity <=1.0%. The preparation comprises dispensing, melting, pre-refining in inert gas, thermal insulating, deoxidizing, charging covering agent, heat preserving and casting.

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.
The high-strength wear-resistance aluminum alloy alloy 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%, Re0.2 ∽ 2.5%, impurity≤1.0%; The preparation method who went up the high-strength wearable McGill metals is: prepare burden by above-mentioned alloying constituent, the starting material that prepare are melted in air atmosphere in heating unit, stay a spot of aluminium, molten clear back air blowing preliminary refining as pre-deoxidant, add pre-deoxidant and carry out deoxidation in advance, 1250 ℃ of insulations, carry out chemical refining and carry out final deoxygenation, slagging-off, air content adds insulating covering agent after the assay was approved, 1260 ℃ of insulations 3-5 minute, the Ex-all bits were 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%, Re0.2 ∽ 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 small amount of aluminum to do pre-deoxidant) in the disposable middle frequency furnaces of packing into such as electrolysis brill, the preliminary refining of molten clear back nitrogen flushing (hydrogen) rare gas element, add the pre-deoxidant pre-deoxidation, be incubated at 1250C, carry out chemical refining and add pure rare earth carrying 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 minute, 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.
