The technologies such as (mist) cooling press quenching extruding, efficient reversed extruding, Isothermal Extrusion.But the aluminium alloy poor for deformation performance
(as 2000 be with 7000 be alloy) and most of magnesium alloy for, because its thermoplasticity is poor, hot cracking tendency strong, Zhi Neng
Process under narrower texturing process conditions.Therefore, only using isothermal extrusion technology, structure property on length direction could be obtained
Uniform product, to meet the strict demand of high-performance squeeze wood.In recent years, the correlational study of Isothermal Extrusion technology and exploitation by
Gradually it is taken seriously.By Isothermal Extrusion, can not only obtain that size shape is stable, the product of even tissue, moreover it is possible to improve its finished product
Rate and production efficiency, meet aluminium alloy extrusions integrally possess it is high than strong, high than mould and the mechanical property of high tenacity, it is to avoid section bar goes out
Now distort, the serious phenomenon such as crackle.
At present, Isothermal Extrusion technology generally has two kinds of implementations, and one kind is using speed controlling Isothermal Extrusion, that is, to pass through
Extrusion speed is adjusted, the extrusion temperature for realizing product keeps constant, such as Chinese invention patent (publication number：CN103100575A it is) public
What is opened is a kind of equi-temperature extrusion method of speed Discrete control, but, this method by extrusion speed curve controlled, due to
In extrusion process, the relative motion extruded between room and aluminium alloy cast rod generates frictional heat to aluminium alloy cast rod, if aluminum
The temperature that alloy casting rod enters extruding room is constant along its length, and extrusion speed keeps constant in extrusion process, aluminium alloy casting
Rod back material experienced the friction process of longer path, have built up into temperature during deformed region, before causing
End exit aluminum alloy extrusion section bar temperature and mechanical property change along its length；Another kind is using temperature distribution gradient
Blank Isothermal Extrusion, i.e., using deformation thermal compensation blank afterbody low-temperature region so that temperature of the blank in mould outlet
Keep constant.Producing the blank of temperature distribution gradient has two methods, is respectively gradient temperature heat method and terraced warm water cold process.
However, research shows that frictional heat is to section bar in the Isothermal Extrusion extrusion process of the blank of temperature distribution gradient
The impact of section temperature nonunf ormity is maximum, has exceeded the heat transfer between plastic deformation heat and metal and tool and mould【Hou Wen
It is flourish. the Heat transfer of aluminium alloy extrusions extrusion process and temperature control research [D]. University of Science ＆ Technology, Beijing, 2015.】.In addition, aluminum
The extruding of alloy is studied and shown, the average friction coefficient of material raises 300 DEG C -500 DEG C with temperature, and from 2.1 1.6 are reduced to【
The equivalent characterization research of friction and wear behavior [D] in bright .6061 aluminum alloy heats extrusion process. Hunan University, 2014:22】.Friction system
Several reductions can significantly reduce equipment energy consumption, can also reduce frictional heat, so as to more accurately control the temperature in crimp region.
Therefore, impact of the frictional heat to thermograde in Isothermal Extrusion extrusion process, not only increases energy expenditure, shortens and squeeze
In the pressure cylinder life-span, also it is unable to reach the high Isothermal Extrusion effect of degree of accuracy.
