Description

Technical Field

[0001] The present invention belongs to the technical field of metal product production, and specifically relates to a metal product and its online solid solution deformation production line and method and application, which are particularly suitable for the production of complex structure aging-strengthened metal products. Background Art

[0002] It is very important for age-strengthening metals to carry out traditional solution-aging treatment or solution-deformation aging treatment after plastic deformation. Among them, solution treatment includes two processes: dissolution and quenching, and deformation aging includes two processes: low-temperature strong plastic deformation and aging. Traditional solution-aging treatment is usually completed by performing offline long-term high-temperature heating, dissolution and quenching, and offline aging treatment on the plastically deformed and cooled age-strengthening metal. There are problems such as insufficient amount of precipitated phases inside the metal, coarse precipitated phases at the grain boundaries, uneven distribution of precipitated phases, and poor strength improvement of the metal. It is difficult to meet the higher comprehensive mechanical properties requirements for age-strengthening metals. Solution-deformation aging treatment is usually completed by performing offline long-term high-temperature heating to dissolve and quench the aging-strengthening metal that has been plastically deformed (called "pre-plastic deformation") and cooled, offline plastic deformation again (called "post-plastic deformation"), and offline aging treatment. After the solution treatment, low-temperature strong plastic deformation is performed to introduce a large number of dislocations into the aging-strengthening metal as non-uniform nucleation sites of the precipitation phase, promote the large-scale and dispersed precipitation of the precipitation phase in the metal, thereby greatly improving the metal strength, so as to solve the above-mentioned shortcomings of the traditional solution-aging treatment; but since the pre-plastic deformation process and the solution treatment process, as well as the solution treatment process and the post-plastic deformation process are all implemented separately and discontinuously offline, there are still problems such as serious energy waste, long production cycle, low efficiency, and high cost. In particular, for complex structural metal products, since their shape and structure are already very complex after the pre-plastic deformation, it is impossible to perform post-plastic deformation after the solution treatment. Therefore, the solution-deformation aging treatment cannot be implemented at all, and only the traditional solution-aging treatment can be carried out, which makes it difficult to further improve the performance of the complex structural metal products.

[0003] Therefore, it is of great significance to develop a new method for online solid solution deformation production of metal products to obtain high-performance aging-strengthened metal products at low cost and high efficiency, especially to solve the production problems of high-performance complex structure aging-strengthened metal products. Summary of the invention

[0004] In view of the above problems, the present invention combines online solution treatment with a continuous plastic deformation production line, introduces online solution treatment between the front plastic deformation section and the rear plastic deformation section of the continuous plastic deformation production line, so that the metal billet is simultaneously and continuously subjected to online front plastic deformation, online solution treatment and online post plastic deformation, having the characteristics of full-process online and continuity, and completing the production of metal products after subsequent aging treatment, and providing a metal product and its online solution deformation production line, method and application, which effectively utilize the waste heat of online front plastic deformation to perform online short-time compensatory heating to achieve full dissolution, and then complete the online solution treatment through online quenching, and also utilize online post plastic deformation to complete the deformation after solution treatment, thereby solving the problem that traditional complex structure aging-strengthened metal products are difficult to perform subsequent deformation aging after solution treatment. By developing online solution deformation technology and combining it with offline aging treatment, an online solution deformation-offline aging (abbreviated as "solution deformation-aging") process is formed, which realizes short process, low energy consumption, high efficiency and low cost to produce metal products with excellent comprehensive performance, which is particularly suitable for the production of complex structure metal products.

[0011] Step 1: feeding the metal blank into the online front plastic deformation section for plastic processing to obtain the initial deformed metal material;

[0012] Step 2: performing an online dissolution treatment on the initially deformed metal material that has just left the online pre-plastic deformation section and entered the online solid solution treatment section, followed by an online quenching treatment, completing the online solid solution treatment to obtain a solid solution metal material;

[0020] Beneficial effects of the present invention:

[0021] 1. The online solution deformation production line for metal products of the present invention places the solution treatment of age-hardened metals between the online pre-plastic deformation and the online post-plastic deformation, forming a continuous production line consisting of the online pre-plastic deformation section, the online solution treatment section and the online post-plastic deformation section, which has the characteristics of full-process online and continuity, making its production process compact, shortening the production line length, saving site space, and being able to effectively utilize the waste heat of the online pre-plastic deformation for online rapid and sufficient solution treatment, shortening the solution time, saving energy and low carbon, short production cycle, high production efficiency, and reducing production costs. At the same time, it realizes further online plastic deformation of the metal after the online solution treatment, and can be used for secondary plastic processing of complex structure age-hardened metal products after solution treatment, breaking through the bottleneck of existing production lines for complex structure age-hardened metal products.

[0022] 2. The online solid solution deformation production method for metal products of the present invention performs online solid solution treatment between the online pre-plastic deformation and the online post-plastic deformation of the aging-enhanced metal product continuous plastic deformation production line, realizing that the online solid solution treatment is immediately performed after the online pre-plastic deformation, and the online post-plastic deformation is immediately performed after the online solid solution treatment, and the online post-plastic deformation is used as the deformation process in the traditional deformation aging treatment, thereby transforming the existing "solid solution-deformation aging" process of metal products into an "online solid solution deformation-offline aging" process, that is, the three traditional "solid solution→deformation→aging" processes are combined into one. The independent offline non-continuous process has become an independent online and continuous "solid solution deformation" process of "solid solution + deformation → aging" combined with an independent offline non-continuous "aging" process, and it also realizes the continuous implementation of pre-online plastic deformation, online solid solution treatment and post-online plastic deformation, which reduces the process, shortens the cycle, saves energy, reduces costs, and solves the problem that complex structure metal products are difficult to perform plastic deformation alone after solid solution treatment in traditional methods, resulting in the inability to perform deformation aging treatment. It is particularly suitable for the production of complex structure aging-strengthened metal products.
