介紹了金屬擠壓技術(shù)的發(fā)展概況以及我國(guó)近十幾年來(lái)擠壓工業(yè)，尤其是重型和超重型擠壓設(shè)備快速發(fā)展的狀況。金屬流動(dòng)變形行為、分流模擠壓焊合過(guò)程與焊合質(zhì)量、組織性能演化與精確控制等基礎(chǔ)理論研究，是正確設(shè)計(jì)模具，預(yù)防缺陷的產(chǎn)生，提高產(chǎn)品質(zhì)量，提高擠壓成材率和生產(chǎn)效率的重要基礎(chǔ)，一直受到研究人員的高度重視。模具的數(shù)字化設(shè)計(jì)與數(shù)字化制造、高性能難加工材料擠壓、等溫?cái)D壓、擠壓成形-彎曲加工一體化、包芯擠壓等擠壓新技術(shù)和新工藝的開(kāi)發(fā)應(yīng)用，是目前擠壓制造技術(shù)的研究重點(diǎn)。總體而言，未來(lái)擠壓技術(shù)發(fā)展方向主要包括3個(gè)方面：一是擠壓產(chǎn)品組織性能與形狀尺寸的精確控制；二是高性能、難加工材料擠壓工藝技術(shù)開(kāi)發(fā)；三是擠壓生產(chǎn)的高效率化和低成本化。
- Abstract:

The extrusion forming technology of metals and the rapid development in extrusion industry of China， especially， in the manufacture of heavy or ultraheavy presses in recent decades are reviewed. The basic theories of extrusion technology such as metal flowing behavior， welding process and performance in porthole extrusion， the evolution and accurate control of microstructure and properties are the important foundations of die design， defect prevention and the improvement of product quality， extrusion yield and efficiency， still attracting great attention from researchers. The development and application of novel extrusion technologies are currently the research emphases， which include digitalized die design and manufacture， high performance difficulttowork materials extrusion， isothermal extrusion， integration of bending and extrusion， clad extrusion， etc. In summary， the trends of extrusion technology in future include three aspects: accurate control of the microstructure and size of the products， difficulttowork materials extrusion and lowcost and highefficiency extrusion process.
