Description
Technical field
The present invention relates to a kind of aluminium alloy, more specifically the present invention relates to a kind of aluminium alloy wires, more specifically the present invention relates to a kind of production method of aluminium alloy wires, relate more specifically to a kind of aluminium alloy wires produced by CONFORM continuous squeezing method, relate more specifically to a kind of aluminium alloy CONFORM continuous squeezing method.
Background technology
Continual extruding technology be 1972 UK Atomic Energy Authority (UKAEA) Springfield institute Green (D.Green) invent, the same year applies for English Patent.Within 1975, bar uncle cock (Babcock) wire rod facility company of Britain has manufactured First CONFORM continuous extruder, drops into the industrial production of aluminium conductor.Britain's Horton (Holten) mechanical means manufacturing companies in 1984 and manufacture portion of Southwire Co. of the U.S. establish First (Castex) continuous casting and extrusion trier, and within 10 years, have manufactured the equipment with the soft aluminium of ten industrial production.CONFORM technology company and Horton mechanical means manufacturing company of Britain joint development particulate material CONFORM continuously extruded, and successfully squeezed out the Aluminum alloy pole material of φ 92mm, its advantage is:
(1) it to have energy consumption low: due to the acting in conjunction of friction and deformation heat in continuously extruded process, aluminium can be made before extrusion without the need to heating, directly feed cold burden and make the temperature of distorted area reach the extrusion temperature of aluminium, thus squeezing out hot goods.Therefore, blank heating device can be saved to Al and Alalloy CONFORM is continuously extruded, greatly reduce power consumption.Comparable conventional extrusion saves the thermoelectricity expense of about 3/4.
(2) material use efficiency is high: in continuous extrusion process of production, except the surface cleaning processing of blank, the process leakage amount of extrusion process, and tool and mould change time defective material outside, due to more than extruding pressure, crop end amount is little, thus material use efficiency is very high, and when production leadtime shows continuously extruded thin-walled soft al alloy disk tubing, material use efficiency is up to more than 96%.
(3) article length is large: as long as continuously to feeding in extruding race, just the unrestricted in theory product of length can continuously be squeezed out, on the production line being furnished with large taking-up equipment, production length can reach thousands of rice, so the soft al alloy disk tubing of the thin-walled of myriametre, electromagnetic wire, aluminium conductor and aluminum-clad steel wire etc.
(4) structure property is even: in continuously extruded, as long as continuously to feeding in extruding race, the processing parameters such as the temperature of blank in distorted area and pressure all can keep stablizing, be similar to very much a kind of isothermal or terraced warm extrusion technology, stablizing just due to processing parameters such as continuous extrusion deformation district temperature and pressure, makes extruded goods structure property uniformity.
(5) blank strong adaptability: continuously extrudedly both can make blank with the Al and Alalloy dish round bar material of continuous casting and rolling or continuous casting, also can use metallic particles or powder as the direct extrusion bar of blank; Simultaneously various continuous casting technology and continuously extruded being organically combined into one can also be formed Castex continuous casting and connect and squeeze, direct use metal melt is squeezed into goods as blank.
(6) production is flexible, efficiency is high: the continuously extruded expanded mode that can adopt squeezes out the product larger than blank specification, and need not heat separately in advance extruding tool and mould and blank in production, break(ing)-in-period is short, and thus production efficiency is high.
In continuously extruded process, the theoretical investigation of metal plastic deformation behavior is also in initial stage, and domestic and international many experts and scholars continuous research work in the experiment, theoretical investigation of continual extruding technology, has promoted the development of continual extruding technology.
CONFORM has energy-conservation, the unique advantage such as work efficiency is high, lumber recovery is high, technical process is short.But to nip the restriction of a variety of causes such as difficulty, blank tissue consistency not good, continuously extruded time length unstable and little wire diameter outlet identical tension rolling difficulty owing to being subject to blank, people, to the application of this technology in aluminium alloy wires processing, also do not carry out deep research.
