Through international online retrieval, do not find and the similar document of the present invention.
Intensity of cooling is big when The present invention be directed to the existing a kind of liquid metal crystallization of producing the deficiency of aluminium Ti, B grain graining agent wire craft and designing, organize fine and closely woven, crystal grain is evenly distributed, and equipment investment is few, floor space is little, the continuous aluminium-titanium-boron wire casting and extruding process of stable and reliable product quality.
Continuous aluminium-titanium-boron wire casting and extruding process of the present invention mainly by get the raw materials ready, melting, stirring, continuous casting and extrusion (comprise cast, solidify, extrude), cooling, alignment and operation such as batch and form.Realize by smelting furnace, continuous casting and extrusion machine and coiling machine etc.The continuous casting and extrusion machine is mainly squeezed boots, material extrusion piece and extrusion die etc. and is formed by frame, chute, the crowded opinion of casting, casting.Casting is squeezed on the surface, outer garden of taking turns and is processed with the ring-shaped groove that can hold alloy liquid, squeeze the lower end of taking turns the crowded boots of casting that match with casting and be provided with extrusion die, the material extrusion piece is near the lower edge of extrusion die, being installed in casting squeezes on the boots, the end of this material extrusion piece is stretched into casting and is squeezed in the groove of wheel, and its shape and groove match.Be to reduce casting and squeeze the wearing and tearing of boots, squeeze wheel and casting in casting and squeeze groove envelope watt is housed between the boots.Wheel is squeezed in casting and the crowded boots of casting all pass through water quench.The melting in the smelting furnace of packing into of ready raw material, add alloying element on request, with the Al-Ti-B alloy liquid agitation of fusion evenly back (also can in the insulation bag, stir) casting of being injected into the continuous casting and extrusion machine by chute continuously squeeze the wheel ring-shaped groove and groove seals in the hole slot of watt formation.The size of cast flow squeezes the rotating speed of wheel according to the crowded hole slot chamber of casting cross dimensions, casting and the diameter of the crowded wheel of casting is determined.By casting the frictional force that produces between crowded rotation of taking turns and the alloy aluminum material alloy material is together rotated with the crowded wheel of casting.The alloy liquid of fusion through dynamic crystallization, semi-molten extruding and plastic deformation three phases, solidifies in the hole slot chamber of wheel and watt formation of groove envelope is squeezed in casting gradually.Control casting and squeeze the rotating speed of wheel and the flow that wheel, the crowded boots cooling water of casting are squeezed in the inflow casting, make alloy liquid enter the deformed area while lowering the temperature.Because it is less that the hole slot of wheel and watt formation of groove envelope is squeezed in casting, around it water quench arranged all, so intensity of cooling is bigger.The aluminium alloy that enters the deformed area squeezes in casting and continues under the drive of taking turns to move, and squeezes in casting under the effect of the material extrusion piece extruding force on the boots, makes alloy become the wire rod shape to extrude continuously from the mould mouth.After the water cooling alignment, batch rolling to coiling machine.The optimum temperature that the alloy liquid of fusion is poured into a mould is between 740-870 ℃; The temperature that enters deformed area extruding place is advisable between 400-500 ℃.Said dynamic crystallization, semi-molten extruding and plastic deformation three phases are meant that the alloy liquid of fusion enters the casting crowded wheel groove of rotation and the cavity of groove envelope watt formation, form the crystallization shell along the chamber wall, shell is along with the rotation of wheel produces the liquid metals friction, crystallization shell and liquid metals make shell thickening gradually in the dynamic friction process, realized the process of dynamic crystallization.Friction in the turbulent condition that alloy material is in liquid-solid phase coexistence produces makes alloy the process of constantly being destroyed again and forming, i.e. semi-molten squeezed state occur constantly forming.The rotation that alloy material after solidifying squeezes wheel along with casting transfers external friction to by interior friction, makes metal generation plastic deformation, is mixed with the generation of crystallization more simultaneously.Material after entering extrusion chamber makes alloy material extrude from the mould mouth under the effect of extruding force, obtains desired aluminium-titanium-boron wire.
Advantage of the present invention is that casting, extrusion molding are finished by an equipment as a procedure, and the intensity of cooling during the liquid metal crystallization is bigger, organize fine and closely woven, be other method produce wire rod can not compare.Continuous casting and extrusion is the continuous process that casting and extruding are combined as a whole, and the cavity cross dimensions that casting is squeezed is little, and cooling velocity is fast, and the crystallization degree of supercooling is big.Reduced the used rolling or extrusion equipment of other technology, saved the energy, reduced floor space, and can make the steady quality of product reliable.
Accompanying drawing 1 is a technological process block-diagram of the present invention.
