Abstract
The invention aims to provide a compact continuous production system of aluminum products, which can save space, has less intermediate stock and short lead time from raw materials to finished products, and a continuous production method based on the system. The device is characterized by continuously comprising: a composition adjustment unit for adjusting the additive composition of the molten aluminum alloy; a continuous casting unit for continuously casting a cylindrical billet using the melt with the adjusted additive component; a billet cutting unit that cuts the continuously cast cylindrical billet into a predetermined length; and an extrusion molding unit that extrudes an extrusion material using the cut billet.
Description
Technical Field
The present invention relates to a continuous production system and a continuous production method for aluminum products, which can continuously perform adjustment of the composition of an aluminum alloy to extrusion molding, and further can continuously perform machining to heat treatment.
Background
Conventionally, a cylindrical billet made of an aluminum alloy is fed into an extruder, and a long extruded material is obtained by a direct extrusion method, an indirect extrusion method, or the like.
In this case, since an extrusion material having a length of several tens of meters is obtained from one billet, a large-sized roll table or cooling table having a length of 40 to 50 meters or more is required, and thus a very large extrusion apparatus or extrusion line is used.
Further, the extruded material must be a long linear material.
In addition, a cylindrical billet for extrusion molding is produced by melting an aluminum ingot (aluminum raw material) in a large melting furnace, adjusting the composition of alloy components, and producing the billet by using a solid type casting machine using a suspension casting method, a hot top casting method, or the like, and a very large casting machine and its accompanying facilities are required, and a large furnace is required because a subsequent tempering furnace is also batch-processed.
In this way, since the billet casting and extruding apparatuses require large-scale apparatuses and additional facilities, they are produced by different enterprises or at least different plants.
Further, since the extruded material is a long material up to several tens of meters, the steps of cutting to a predetermined length to a fixed length, bending, and other machining to obtain a finished product become a mass production system divided into the respective steps.
In such a conventional production mechanism, since the production is performed by division in a large-scale unit, not only a large amount of stock management is required for each process of a raw material, an intermediate product, a finished product, and the like, but also a process from a raw material to a finished product reaches several days, which causes a problem of a long lead time.

Disclosure of Invention
DISCLOSURE OF THE INVENTION
Technical problem to be solved by the invention
The invention aims to provide a compact continuous production system of aluminum products, which can save space, has less intermediate stock and short lead time from raw materials to finished products, and a continuous production method based on the system.
Means for solving the technical problem
The present invention relates to a continuous production system for aluminum products, which is characterized by continuously comprising: a composition adjustment unit for adjusting the additive composition of the molten aluminum alloy; a continuous casting unit for continuously casting a cylindrical billet using the melt with the adjusted additive component; a billet cutting unit that cuts the continuously cast cylindrical billet into a predetermined length; and an extrusion molding unit that extrudes an extrusion material using the cut billet.
Here, the composition adjusting means for adjusting the additive components is means for melting an aluminum raw material such as an ingot in a furnace, and adding a master alloy of various components such as Mg, Zn, Si, and Cu to adjust the composition of the molten metal.
For example, a melting furnace, a regulating furnace, a tapping furnace, and the like may be provided in series, and the continuous casting unit for continuously casting a cylindrical billet may be combined with a continuous casting unit for adjusting a melt in each furnace and pouring the melt from the tapping furnace to a casting die of the billet.
At present, a hard-type casting machine such as a hot-top type is used, but the present invention uses a horizontal type continuous casting machine capable of continuously casting and extruding a desired billet in the horizontal direction using a horizontal type casting die.
Thus, a billet for extrusion can be obtained by cutting a cylindrical continuous casting rod cast in the transverse direction into a desired length.
The cut billet obtained in the above manner is supplied to an extrusion press and extruded, but the billet may be homogenized by a tempering furnace before the supply.
The present invention may also have a thermal bending processing unit that directly performs bending processing in a hot state on an extrusion material extruded by extrusion molding.
Here, the bending of the extruded material directly in a hot state means that the extruded material extruded from the extrusion die is heated to a high temperature and is subjected to necessary bending before being cooled.
In this case, the high-temperature extrusion material may be cut into a predetermined length and bent by a bending machine.
Further, a roll bending device may be provided, for example, three-point roll bending, and the extruded material extruded between the rolls may be continuously bent while passing through the roll bending device in this state.
Further, in order to cut the product material while pressing, a traveling cutter may be provided, and the traveling cutter may travel the cutter to cut the material while matching the extrusion speed at which the material is extruded.
In the present invention, a machining unit that performs other machining such as punching or pressing on the bent material may be continuously provided.
Further, a heat treatment means for performing heat treatment of the machined workpiece may be provided continuously.
The continuous production method using such a production system is characterized by comprising: step (1), adjusting the composition of molten aluminum alloy; step (2), continuously casting a cylindrical billet by using the melt after the composition adjustment; a step (3) of cutting the continuously cast cylindrical slab into a slab having a predetermined length; a step (4) of extruding and forming an extrusion material by using the billet; and (5) bending the extruded material in a hot state after extrusion molding, and continuously performing the steps (1) to (5).
ADVANTAGEOUS EFFECTS OF INVENTION
The present invention relates to a system for continuously producing aluminum products, which can continuously produce aluminum materials from a melting step to an extrusion molding step of the extruded materials by a compact apparatus, and thus can save space and shorten lead time.
In addition, an intermediate stock such as storage of a conventional billet is not required.
In the present invention, if the steps of machining such as bending and hole cutting, and heat treatment of the processed product are continuously constructed, intermediate stocks are further reduced, and lead time is shortened.
