Description
Technical field
The utility model relates to a kind of aluminium spout.
Background technology
The aluminium spout is the critical component on the large aluminum alloy die casting production line, and it is to guarantee that high temperature aluminum liquid enters the passage of pressing the chamber smoothly.The aluminium spout often lost efficacy because of intermittently for aluminium thermal fatigue cracking taking place, about 680 ℃ of aluminium liquid pouring temperatures, when high temperature aluminum liquid passes through the aluminium spout, its working face raises rapidly because of heat conduction temperature, because the chute wall thickness is 4 mm～5 mm, exist thermograde at the chute thickness direction this moment, and the expansion of high-temperature region material is restricted, and will produce compression; After high temperature aluminum liquid passes through the aluminium spout, its working face temperature reduces rapidly, still has thermograde at the chute thickness direction, causes chute material deformation amount disunity, the contraction of low-temperature space material is restricted, to produce tension, repeat stress causes working face germinating heat fatigue cracking, and along with the increase of times of thermal cycle, crackle can further expand, finally cause the chute cracking, aluminium liquid can't be flowed into smoothly press the chamber, so just can not finish press casting procedure.Simultaneously, also have two factors to quicken aluminium spout heat fatigue and destroy, the one, chute in use oxidation is serious, the generation of top layer oxide skin with come off, and the oxidation of crackle both sides and tip materials makes the material fragility increase; The 2nd, penetrate into after aluminium liquid in the crackle solidifies oxidation, be equivalent in material, embed the impurity of high rigidity, thereby accelerated the expansion rate of crackle.
The fracture of aluminium spout and the safety of destroying meeting serious harm production equipment and operating personnel.At present, extensively the means of defence that adopts is at aluminium spout working face brush coating, play heat insulation, etch-proof effect, but this coating is difficult to stand washing away of high temperature aluminum liquid, can lose protective action very soon.According to investigations, only be 0.5～1 month aluminium spout service life of being made by homemade carbon steel, changes very frequently, influences production efficiency, and waste of material is serious; The aluminium spout of being made by the import carbon steel can reach 2 months service life, but price is more expensive, is about 4 times of homemade chute, has increased the production cost of producer.
Summary of the invention
The purpose of this utility model is at above-mentioned existing problems and deficiency, provides a kind of and has good antioxygenic property and thermal fatigue resistance, and simple and reliable for structure, easily manufactured, the low good aluminium spout of security performance that reaches of cost.
The technical solution of the utility model is achieved in that
Aluminium spout described in the utility model comprises aluminium spout matrix, is characterized in that described aluminium spout matrix is provided with some alloy bands.
In order to reach the purpose of this utility model, above-mentioned each alloy band is arranged on the working face of above-mentioned aluminium spout matrix.
In order to prevent the aluminium spout in the process of using, alloy is taken the phenomenon that now comes off out of, and above-mentioned each alloy band and aluminium spout matrix link together by the mode of metallurgical binding.
The utility model is because employing is provided with some alloy bands on aluminium spout matrix, utilize alloy band good heat-conducting and antioxygenic property, greatly improved the thermal fatigue resistance of aluminium spout, and as can be known through repeatedly test, the thermal fatigue resistance crack initiation ability of aluminium spout improves 0.5 times at least, thermal fatigue resistance crackle extended capability improves 1.5 times at least, the comprehensive life of aluminium spout improves 1 times at least like this, and use stable, can realize periodic replacement, thereby ensure the die casting production safety effectively.And between alloy band and the aluminium spout matrix is metallurgical binding, the aluminium spout in the process of using, the phenomenon that the alloy band can not occur coming off, thus guaranteed the metallurgical quality of die casting.Simultaneously, the cost amplification of alloying band can not surpass 30% of the whole cost of aluminium spout, thereby helps reducing the die casting production cost.In addition, owing to be to bring the thermal fatigue resistance that improves the aluminium spout by alloy, the material that therefore is used to make aluminium spout matrix just can be selected cheap ordinary carbon steel, thereby has guaranteed lower manufacturing cost, helps marketing.Again owing to need not brushing paint, thereby reduced working strength of workers at the working face of aluminium spout matrix.The utility model also has advantages such as simple and reliable for structure and easily manufactured.
Below in conjunction with accompanying drawing the utility model is further described.
