Abstract
The invention relates to a copper-based alloy and a forming method thereof, which are suitable for producing metal products with high strength and high wear resistance, in particular to the production of automobile synchronizer materials, and are characterized in that: the alloy components are reasonably designed, rare earth elements are added, a vertical continuous casting method is adopted, technological parameters are strictly controlled, and under the action of electromagnetic strong stirring, an alloy solution is solidified at a certain position in a crystallizer and is cast into a pipe, so that the technical problem of vertical continuous casting of brass alloy with more than five elements is solved, the high-quality pipe is produced in batches, the production period is shortened, the production cost is reduced, the yield reaches 80%, and the brand and specification can be changed as required.
Description
The present invention relates to the method for copper base alloy and moulding thereof, this alloy is suitable for the metal products of production high strength, high-wear resistance, especially is applied to the production of automobile synchronizer tooth ring material.
Automobile synchronizer tooth ring material research both at home and abroad is more, generally is to add Al on the brass basis, Mn, and Si, Fe, Co, the Ni element is to gain in strength and wear resisting property; Its tube forming method has centrifugal casting, extrusion process, and horizontal casting method etc., but all have weak point.As:
Japanese car company adopts the vacuum centrifugal casting method for producing wear-resistant brass pipe, this method apparatus expensive, and investment is big; German automobiles company then adopts continuous casting-hot-pressed method, long flow path, cost height; Domestic automobile manufacturer removes and adopts antivacuum centrifugal casting, outside the hot extrusion method, also adopts the horizontal casting method, see patent 93120535, but this method gravitate easily produces gravity segregation, causes composition inequality and wall thickness deviation big.
The objective of the invention is to overcome the defective of prior art, and a kind of polycomponent wearable is provided, high-intensity brass alloys and it is prepared into the method for tubing, and also this method is with short production cycle, and production cost is low, the yield rate height.
The present invention is that the technical scheme that adopts that achieves the above object is:
The appropriate design alloying constituent is added rare earth element, and alloying constituent (wt%) is: Cu56-65%, Al 0.9-6.0%, Mn 1.5-7.0%, Si 0.4-0.8%, Fe0.5-1.0%, Sn 0.1-0.3%, Pb 0.1-0.3%.
Add rare earth Re:0.05-0.4%, the adding of rare earth element to be purifying crystal boundary, and crystal grain thinning improves the tissue and the performance of wear resistant brass.
Adopt the vertical continuous casting method, the appropriate design crystallizer, control furnace temperature, hydraulic pressure, pouring temperature, and processing parameter such as speed of cooling, casting speed strengthen foreign field simultaneously, the magnetic field that ruhmkorff coil is caused reaches crystallizer, under the powerful stirring action of electromagnetism, alloy solution is solidified on certain position in crystallizer, produce high-quality tubing.
The present invention compared with prior art, its unusual effect and advantage show as:
Solved the technical barrier of five kinds of above brass alloys vertical continuous castings of element, mass-produced high-quality tubing, shortened the production cycle, reduced production cost, yield rate reaches 80%, also can change the trade mark and specification according to user's needs.
Be described further below in conjunction with embodiment.
The production technique of example 1:Hal 62-4-3-0.1 wear resistant brass pipe.
At first prepare burden
Its constituent element ingredient w t% is:
Cu：56-62 Al：2.7-4.5 Mn：2.5-3.5
Si：0.4-0.8 Fe：0.5-1.0 Sn：0.1-0.3
Pb:0.1-0.30 is rich, and Ce:0.05-0.40 Zn is a surplus.
Alloy is configured to the master alloy fusing point and just is sequentially added in the smelting furnace, through the composition adjustment, and refining, degasification, slagging-off; Melt is become brass alloys tubing by cast immediately from smelting furnace, through holding furnace, to crystallizer when temperature reaches 1100 ℃, and its pouring temperature is T
Water℃=1050 ± 5 ℃, casting speed is V
Draw=6.0-8.0cm/min.
The performance index of tubing reach:
