Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of complex al-brass of high-strength wearproof corrosion-resistant is provided.
For achieving the above object, the present invention takes following technical proposals to realize:
A kind of high-strength abrasion-proof complex al-brass has following moiety (weight ratio): the copper of 66.0%-71.5%, and the aluminium of 2.0%-7.5%, the iron of 2.5%-5.0%, the manganese of 0.3%-0.7%, the silicon of 0.2%-1.1%, surplus is the impurity under zinc and the preparation condition.
Preferably, a kind of high-strength abrasion-proof complex al-brass has following moiety (weight ratio): the copper of 68.5%-71.0%, the aluminium of 3.5%-4.5%, the iron of 3.0%-4.0%, the manganese of 0.4%-0.6%, the silicon of 0.7%-0.8%, surplus are the impurity under zinc and the preparation condition.
Among the present invention, described high-strength abrasion-proof complex al-brass alloy is produced qualified bar through following process.
A kind of method of producing high-strength abrasion-proof complex al-brass bar, concrete steps are: adopt first underflow type horizontal continuous casting machine continuous casting aluminum brass ingot, by the take-up of large-tonnage indirect extrusion machine, by Shu Gema associating drawing unit, realize follow-up drawing, sawing chamfering, flaw detection, packing at last again.
In the present invention, described high-strength abrasion-proof complex al-brass preferably is used for the manufacturing of the component such as engine valve guide, bearing or selector fork, is used in particular for above-mentioned parts in the automobile.
Compared with prior art, the present invention has the following advantages: rational proportion has added the elements such as aluminium, iron, manganese, silicon, prepares the high strength degree, and wear resisting property is good, and corrosion resistance is good, and processing characteristics is excellent, the complex al-brass that cost is relatively cheap; Adopt underflow type horizontal continuous casting copper ingot, then large-tonnage indirect extrusion machine take-up, Shu Gema on-line Control associating drawing unit is realized follow-up drawing, the sawing chamfering, flaw detection and packing, on-line automatic control, labour intensity is low, production efficiency is high, and Product Precision is high, has reduced simultaneously energy consumption.
Description of drawings
Fig. 1 is the production unit synoptic diagram of high-strength abrasion-proof complex al-brass of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with the technological process of production and embodiment.
The technological process of production of high-strength abrasion-proof complex al-brass is as shown in Figure 1:
Step a adopts the horizontal continuous caster 1 continuous production of copper ingot blank of undercurrent type environment-friendly type.
The horizontal continuous caster of described undercurrent type environment-friendly type comprises melting mechanism 11, haulage gear 12 and saw cutting mechanism 13.
Melting mechanism stove group is conjuncted furnace, and the metal chute has been cancelled in the transhipment of undercurrent type metal melt, directly connect by totally enclosed valve formula water conservancy diversion secret tunnel between smelting furnace and the holding furnace, air-breathing and oxidation when having prevented the metal transhipment reduces the volatilization of zinc oxide, has reduced the loss of Metal Melting.In better embodiment of the present invention, single ingot metal wastage reduces by 0.5%.
Haulage gear and saw cutting mechanism are realized the serialization production of copper ingot base by the control of PLC Controlling System.
Step b extrudes copper rod by large-tonnage indirect extrusion machine 2 again.
Described indirect extrusion machine is compared with the forward extrusion machine, has reduced the frictional force between copper ingot base and the container, and the required squeeze pressure of reverse extrusion only has 2/3 of forward; Metal flow nonaffine deformation district is less, can effectively reduce contracting tail phenomenon, reduces process residue about 15%, has improved the extrusion bar rate.
Step c, the copper ingot base after the extruding are by Shu Mage associating drawing unit 3, and on-line automatic control realizes follow-up drawing, sawing chamfering, flaw detection, packing.
The above-mentioned drawing of traditional complete processing, sawing chamfering, flaw detection, each operation of packing work alone, and labour intensity is large, and the bar size precision of production is not high.Among the present invention, on-line automatic control, labour intensity is low, and production efficiency is high, shortens man-hour, and the bar size precision is high simultaneously.Preferably among the embodiment, the bar size precision of producing reaches 0.01mm one of the present invention, and linearity reaches 0.3mm/m.
Embodiment one, and the high-strength abrasion-proof complex al-brass bar that adopts the above-mentioned technical process of the present invention to produce has following moiety (weight ratio): 66.0% copper, 2.0% aluminium, 5.0% iron, 0.3% manganese, 1.1% silicon, surplus are the impurity under zinc and the preparation condition.
