The specific embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Fig. 2 is the profile of the spray band pack assembly of the embodiment of the invention, Fig. 3 is the partial enlarged drawing of profile of the spray band pack assembly of the embodiment of the invention, as Fig. 2, shown in Figure 3, nozzle 202 is arranged at spray band bag 201 bottoms, molten metal 203 is ejected on the crystallization roller 204 from nozzle 202, crystallization roller 204 clockwise directions rotate, and molten metal 203 forms amorphous alloy strips through cooling off fast, and the molten metal 203 between nozzle 202 and the crystallization roller 204 is referred to as weld pool 205.When weld pool 205 is directly exposed in the air, produce bubble at the contact-making surface with crystallization roller 204 easily, thereby make the amorphous alloy strips surface produce defective, seriously reduce the toughness on amorphous alloy strips surface; Weld pool 205 very easily oxidation in air simultaneously, oxide buildup cause nozzle 202 to stop up or cause the amorphous alloy strips density not high at nozzle 202 edges, when serious even cause producing and stop.In order to solve this difficult problem, the spray band pack assembly of the embodiment of the invention arranges graphite bar 206 around nozzle 202, and graphite bar 206 plays a protective role to weld pool 205 from all around weld pool 205 being surrounded.In spray band process, under the hot conditions, 206 oxidations of graphite bar, generate reducibility gas carbon monoxide and carbon dioxide, make that the molten metal 203 of weld pool 205 is not oxidized, graphite bar 206 stops because the laminar winds that the 204 high speed rotations of crystallization roller produce enters weld pool 205 simultaneously, has significantly reduced the number of bubbles of weld pool 205 with the contact-making surface of crystallization roller 204.
Fig. 2, shown in Figure 3 for another example, see that for clearer graphite bar 206 and the position of nozzle 202 concern, only provided the graphite bar 206 of nozzle 202 left and right sides among Fig. 2, Fig. 3, omitted the graphite bar 206 of nozzle 202 back, in the profile of the spray band bag of reality, also should there be the graphite bar back of nozzle, has just omitted the graphite bar of nozzle back among Fig. 2, Fig. 3 for the ease of observation.
When crystallization roller 204 rotates along clockwise 207 directions, driving air also is to move along clockwise direction, with respect to weld pool 205, wind also is to move along clockwise direction, direction called after air inlet 208 with the wind initiation, with the direction called after air outlet 208 of wind to weld pool 205 another sides, see the concrete sign among Fig. 2 for details.If crystallization roller 204 is along counterclockwise rotating, with respect to weld pool, wind also is to move in the counterclockwise direction, then clockwise rotates with the crystallization roller and compares its air inlet and the air outlet direction is opposite.
As Fig. 2, shown in Figure 3, the graphite bar 206 of close import wind 208 is a with the distance of crystallization roller, the nozzle 202 of close import wind 208 is b with the distance of crystallization roller, the nozzle 202 of close air outlet 209 is c with the distance of crystallization roller, is d near the graphite bar 206 of air outlet 209 and the distance of crystallization roller.In embodiments of the present invention apart from a less than distance b, distance b is less than distance c, distance c is less than distance d; Concrete, the smaller the better apart from a, the wind of coming in the more little then import of a wind 208 places is more few, and then graphite bar 206 area surrounded environment are more stable, and weld pool 205 is more few with the number of bubbles of the contact-making surface of crystallization roller 204.Preferably, the value of a is between 0.5～1mm; Distance b and distance c are to determine according to the thickness of the amorphous alloy strips that sprays, when the amorphous alloy strips that will prepare is thicker, then distance b and distance c are big a little, when the amorphous alloy strips that will prepare is thinner, then distance b and distance c are smaller a little, need to prove that distance b is for the ease of forming weld pool 205 less than distance c; Distance c is less than distance d, be because the present invention also comprises a measuring height device 210, measuring height device 210 is used for measuring the height of the weld pool 205 that sprays the band process, measuring height device 210 is positioned at the one side near air outlet 209, distance c is in order not hinder measuring height device 210 to measure the height of weld pool 205 less than distance d.
Fig. 4 is the location map of the spray band pack assembly of the embodiment of the invention, as shown in Figure 4, will be along the direction called after vertical 401 of crystallization roller 204 rotations, will be perpendicular to the direction called after horizontal 402 of crystallization roller 204 rotations, graphite bar 206 is e with the distance of nozzle 202 on vertical 401, graphite bar 206 is f with the distance of nozzle 202 on horizontal 402, is f apart from e greater than the distance of graphite bar on horizontal 402 206 and nozzle 202 at graphite bar on vertical 401 206 and nozzle 202 in the embodiment of the invention, because in spray band process, on horizontal 402 namely in two short easier outflows of side wind of nozzle 202, thereby on will horizontal 402 graphite bar 206 and nozzle 202 apart from f design littler.
