Description
Technical field
The invention belongs to the technical field of rapid solidification metal, specifically a kind of rapid solidification prepares method and the device of sheet metal strip.
Background technology
Rapid solidification metal technology has obtained and has developed fast since appearance, rapid solidification can obtain high cooldown rate, significantly improve the structure and properties after liquid metal solidification, early stage fast solidifying technology is for obtaining the sheet metal of rapid solidification, this technology can realize the manufacture of metal dust, thin wire and strip at present, thus is widely used.Wherein rapid coagulation band both can be applied as the final products of direct forming, also to following process such as it are rolled further, can become the topmost application of flash set technology.Strip soon solidifying technical matters scheme is mainly divided into roll-type (single-roller method and double roller therapy) and roller belt-type etc. because of the difference of crystallizer.
Single-roller method (melt spin method), adopts the Quench round roller of High Rotation Speed aluminium alloy stream is sprawled into liquid film and realize rapid solidification under chilling action, because the method principle is simple and equipment investment is few, current most widely used general.But there is significant defect in single-roller method---when 1. producing under non-vacuum environment, the roll surface wind that roller high-speed rotation is brought causes spray liquid flow and has a strong impact on, cause technical process unstable, therefore, need to adopt single roller sheet-like flow method, rely on strict Control Nozzle and the gap (100 ~ 300 μm) of roll surface to realize the stable stream that goes out to become to be with, require extremely strict to device manufacture and adjustment; 2. after molten metal contacts to roller periphery, be subject to the effect of centrifugal force at once, be very shortly namely thrown off in the roll surface time of staying, be difficult to strengthen cooling effect.
For reducing this adverse effect of centrifugal force, also been proposed the method for the fast solidifying band of the inner headed face preparation utilizing roller, as Chinese invention patent 200410009581.1 discloses a kind of method that rapid solidification prepares amorphous thin ribbon, first cooling body is designed to cylinder annular, molten bath is placed in cooling body ring, and the liquid of melting is vertically ejected into inner wall of rotary drum; Then, in cooling body ring, install an elastic rotary axle, axle periphery is coated with a little mucus, and to cling initial strip, axle rotates with certain speed, by the strip of generation around on axle; According to the radius ratio of inner ring and rotating shaft, the relative rotation speed of both adjustments, makes injection and strip winding carry out simultaneously; Finally extract rotating shaft out cooling body, obtain fast solidifying strip.It adopts cylinder annular cooling body, the inwall of cylinder is utilized to cool, but obtain wide and long fast solidifying band, length and the diameter of requirement cylinder are all enough large, for obtaining smooth fast solidifying belt surface, require that inner wall of rotary drum surface must be refined, and, a period of time that often works also must be refined inner wall of rotary drum cooling surface and clear up, cause manufacturing, maintenance difficulties is all very large, and at drums inside, strip crimping device must be installed, operation is used all to have inconvenience, on the other hand, the bored roll that major diameter is longer again will realize stable high-speed rotation, also there is more difficulty.
Produce for adapting to broadband, someone proposes double roller therapy again, and make to complete in the gap of molten metal between two rollers and solidify and obtain fast solidifying strip, this method can produce wider strip and production efficiency is higher, obtains a wide range of applications at present in thin strap continuous casting is produced.But the method exists significantly not enough: one is the side seal problem of molten metal, production practices show, the continuous casting failure probability caused because of side seal reaches more than 60%, and the consumption of side seal material accounts for more than 20% of strip base production cost, improves production cost and destroys the stability of production process; On the other hand, the cooling velocity that the results show double roller therapy can reach is not ideal enough, there is the contradiction of production efficiency and strip quality control, enhance productivity, just need to promote bath surface height to extend the contact range (i.e. effective cooling distance) of molten metal and roll surface, but the raising of liquid level directly brings, and segregation is serious, side seal is more difficult, solidify terminating point is difficult to the problems such as control, causes the quality variation of strip base.
One of striving direction improving cooling condition with method, as SCR milling train, increase the cooling steel band that holds a wherein roller between two rolls, make motlten metal at steel band and held cooled and solidified between chill roll, improve cooling condition to a certain extent, but complex structure and there is the side seal problem of molten metal equally, and salband is in the high-tension service condition under hot conditions all the time, and service life is very short.As Chinese invention patent 00106176.3 discloses a kind of method of sheet metal strip quick solidification forming, the cooling steel band (3) (3 ') that cooling is implemented at the back side is supported by driven roller (6) (6 '), registration roller (4) (4 ') and idler roller (5) (5 '), forms cooled region; Cooling steel band moves with linear velocity 0.1 ~ 20m/s under the drive of driven roller, motlten metal (1) enters cooled region by crucible (2) under pressure, be cooled in motion process and realize quick solidification forming, preparing the solidified metal band of thickness 100 μm ~ 2mm.It adopts two closed salbands, cooled and solidified region is formed between two salbands, this can regard the distortion of double-roll type as, although adopt belt cooling to improve coagulation efficacy, but because the side seal of driving-belt is more difficult, and cooled and solidified district controls the thick in size of fast solidifying band by salband completely, because salband is difficult at the poor rigidity of thickness direction the thickness evenness ensureing fast solidifying band.
