Abstract
The present invention relates to the preparation of massive non-crystal alloy, and the continuous casting and rolling process of massive non-crystal alloy features that according to cross section shape and length size of the massive non-crystal alloy product and the hole caliber of the water cold rollers in selected and the bite size is regulated so as to cast and roll continuously. Massive non-crystal melt is made to flow through crucible and flow rate controlling plunger and sprue to casting mouth, and then injected homogeneously and continuously into the bite between two water cold rollers rotating in opposite directions so as to produce the massive non-crystal alloy product. The present invention can realize continuous production in low cost and expand the application range of massive non-crystal alloy.
Description
Affiliated technical field
The present invention relates to the bulk amorphous alloys preparing technical field, particularly relate to the bulk amorphous alloys continuous casting rolling technology.
Background technology
Because the structural particularity of amorphous alloy material (shortrange order) makes it compare with traditional crystal alloy material and has more excellent mechanical property, resistance to corrosion, chemism, the expansion characteristics of good soft magnetism, Hard Magnetic and uniqueness etc.Just because of this, since nineteen sixties, amorphous alloy material not only is subjected to paying close attention to widely aspect civilian, and also having caused the very big attention of world military power in some military fields, each key industry power has all dropped into great amount of manpower and material resources and has carried out the research and the application and development of various amorphous alloy materials in the world.Non-crystaline amorphous metal the earliest need be in very big cooling velocity (＞10
6K/s) could obtain down, this moment, non-crystaline amorphous metal can only exist with powder, silk, strip low-dimensional forms such as (tens microns), had weakened giving full play to of non-crystaline amorphous metal performance potential greatly, had limited non-crystaline amorphous metal being extensive use of in industry.Therefore, since the eighties latter stage in last century, preparing large-sized amorphous alloy material becomes one of primary study direction in the new material research field.At present, bulk amorphous alloys technology of preparing majority still is in laboratory level, as suction pouring and die-casting technique, copper mould casting technology, shrend technology etc., prepared block non-crystalline alloy material majority is single batch, undersized rod, plate, ring etc., can't extensively popularization in industry.
Summary of the invention
Be difficult to satisfy the technical problem that commercial Application requires in order to overcome present bulk amorphous alloys single-piece preparation.The invention provides a kind of bulk amorphous alloys plate (band) material, bar vacuum continuous casting and rolling manufacturing technology, this invention is in order to adapt to industrialized mass production and to reduce production costs,
The technical solution adopted in the present invention is: under vacuum condition, adopt the casting of water-cooled roll to prepare bulk amorphous alloys plate (band) material, bar and special-shaped section bar, by regulating water-cooled roll Pass and roller gap size thereof, the bulk amorphous alloys product of preparation different length and different cross section shape.
The invention has the beneficial effects as follows that bulk amorphous alloys production serialization can reduce cost, and widen the range of application of bulk amorphous alloys simultaneously.
Description of drawings
Fig. 1 is a bulk amorphous alloys rolling casting technology schematic diagram.
In Fig. 1,1, plunger, 2, crucible, 3, the non-crystaline amorphous metal melt, 4, cast gate, 5, pouring mouth, 6, the water-cooled roll, 7, cooling water, 8, the non-crystaline amorphous metal product.
The specific embodiment
Under vacuum condition, according to the cross sectional shape and the length dimension of bulk amorphous alloys product 8, select the pass of water-cooled roll 6, suitable dimensions is adjusted in the gap of two counterrotating water-cooled rolls 6, bulk amorphous alloys is successive during with the assurance casting; The pass of water-cooled roll 6 is rectangle, circle and special-shaped.The bulk amorphous alloys melt 3 of fusing, by crucible 2, the plunger 1 of controlling its flow, cast gate 4, it is flow in the pouring mouth 5, evenly constantly inject the roll gap of water-cooled roll 6 then, and roll out corresponding bulk amorphous alloys product 8 by two counterrotating water-cooled rolls 6.Described water-cooled roll 6 can be that steel also can be a Cu alloy material, and a cavity is arranged in the water-cooled roll 6, can lead to recirculated cooling water 7 in its cavity.Plunger 1 bottom shape is identical with the shape of cast gate 4, and plunger 1 can move up and down with respect to cast gate 4, the flow of control bulk amorphous alloys melt 3; The cross sectional shape of pouring mouth 5 and length dimension depend on the cross sectional shape and the length dimension of prepared bulk amorphous alloys product, and pouring mouth 5 can be the circle mouth, also can be to twitch one's mouth; The contact shape at position of pouring mouth 5 lower ends and roll is identical with water-cooled roll 6 cylinders, and and roll between distance adjustable.
