Description
Technical field
The utility model belongs to technical field of metallurgical equipment, particularly a kind of aluminium alloy wires continuously-casting system.
Background technology
Aluminium alloy wires refers generally to the aluminium alloy wires of below diameter 6mm, also has the wire rod reaching 8-10mm.Aluminium alloy wires general reference below 10mm alleged by the utility model, thin and long aluminium alloy material.This rank aluminium alloy wires both can be used as common product and had used, and also can be used as the wire rod of more minor diameter or the raw material of silk material production.Because it is of many uses, obtain a large amount of production at present.Its production technology general comprises the multiple tracks processes such as casting, heat treatment, machined, hot extrusion, cold extrusion; Also required diameter wire rod can be formed via the one-shot forming of continuous casting and extrusion technology.But the former relates to heating for multiple times, heat treatment and extrusion process in process of production, cause energy waste, environmental pollution, production efficiency is not high.And continuous casting and extrusion process is not high owing to make use of intensity in aluminium alloy semi-solid process, aluminium alloy melt is set in squeezing groove, and it is extruded to carry it into press shoe.This technology has two main points, and the first, melt needs coagulation forming in squeezing groove, ensures that semi-solid blank can rotate to press shoe along with squeezing groove; The second, the intensity of aluminum alloy after coagulation forming can not be too high, because the extruding force in press shoe derives from the frictional force between squeezing groove and aluminium alloy material.Therefore, its operating temperature range is limited, should ensure melt forming, again can not temperature too low.For these reasons, the restricted application of aluminum alloy cast extruding process, be difficult to application, or the rate that manufactures a finished product is too low in a lot of extraordinary aluminium alloy is produced.
Aluminium alloy continuous casting rolling technology is the sixties in last century, originates from an aluminum alloy slab forming technique of Regius professor, gets a lot of applications in the whole world at present.Aluminium alloy melt to be dispersed on roll surface by the lip of a particular design by this technology to be solidified, and reaches given thickness and be shaped to sheet material after roll-in.Because aluminium alloy melt direct pouring is solidified by this technology on roll surface, be difficult to the one dimension wire rod accurately controlling to form required cross section, or different in nature sheet material, therefore this technology still just uses as the production technology of plate in a large number.
Utility model content
The purpose of this utility model is to provide a kind of aluminium alloy wires continuously-casting system, for the deficiency of existing aluminium alloy wires production equipment, a kind of economy of proposition, easy, is applicable to the continuously-casting system that aluminium alloy wires is produced.
The technical solution of the utility model is, a kind of aluminium alloy wires continuously-casting system, and this system comprises the tundish for transporting aluminium alloy melt, below described tundish, be connected with crystallizer, below described crystallizer, be provided with twin-roll cast-rolling mill,
Described aluminium alloy wires continuously-casting system also comprises the seeding mechanism be positioned at below twin-roll cast-rolling mill, before casting starts, by seeding mechanism, seeding head is sent in described crystallizer through twin-roll cast-rolling mill, after aluminium alloy melt pours into tundish, after crystallizer cooling, above seeding head, form solidified shell, solidified shell enters the Casting Roller of twin-roll cast-rolling mill under seeding mechanism pulling function, forms required profile after roll rolipass design rolling.
The outside of described tundish has Tundish Heating device, and can guarantee that the homogeneous temperature of aluminium alloy melt in tundish is stablized, the cooling in tundish holding process is no more than 5 DEG C.
Described crystallizer is water mold, comprises water collar, aluminium sleeve and graphite cannula from outside to inside.
The internal diameter of described water mold is greater than the 5-10% of produced gauge or diameter of wire.
Described seeding mechanism, the seeding head external diameter of its seeding bar is identical with produced gauge or diameter of wire, and pulls control by seeding mechanism.
Described twin-roll cast-rolling mill is water-cooled twin-roll cast-rolling mill, and the synchronous opposite direction rotating of two roller, roll surface is processed with groove.
The roll surface of described water-cooled twin-roll cast-rolling mill is processed with semi-circular recesses, and groove internal diameter is identical with processed gauge or diameter of wire.
The utility model provides a kind of continuous casting rolling technology of aluminium alloy wires, by tundish, and crystallizer, double-roll rolling mill and crystallization device composition.Belong to metal material processing and field of metallurgical equipment.After aluminium alloy melt after refining degasification proceeds to holding furnace, tundish is being entered to fixed temperature casting, the crystallizer similar with wire rod external diameter is connected with below tundish, melt is scull in a crystallizer, and under the pulling force effect of seeding mechanism, enter into water-cooled double-roll rolling mill cooling forming further.This system architecture is simple, and easy and simple to handle, safe and reliable, cost is low, can the following aluminium alloy wires of one-shot forming 10mm.Avoid conventional aluminum alloy wire production process through multi-pass processes such as casting, heat treatment, machined, hot extrusion, cold extrusions, save a large amount of energy, and decrease the environmental pollution in production process.
