锻件需求每片都是一起的，没有任何多孔性、剩下空间、内含物或其他的瑕疵。这种办法出产的元件，强度与重量比有一个高的比率。这些元件通常被用在飞机构造中。锻件的利益有可拓展的长度、可缩短的横截面;可缩短的长度、可拓展的横截面;可改动的长度、可改动的横截面。你知道环型锻件加工的技术要求吗?

　　Each piece of the forging needs to be joined together without any porosity, space, inclusions, or other defects. The component produced by this method has a high ratio of strength to weight. These elements are usually used in aircraft structures. The interests of forgings have an extended length, a shortened cross section, a shortened length, an extended cross section, a variable length, and a variable cross section. Do you know the technical requirements for machining ring forgings?

　　锻件在石油化工设备中有着广泛的运用。如球形储罐的人孔、法兰，换热器所需的各种管板、对焊法兰催化裂化反应器的整锻筒体(压力容器)，加氢反应器所用的筒节，化肥设备所需的顶盖、底盖、封头号均是锻件。

　　Forgings are widely used in petrochemical equipment. Such as spherical tank manhole, flange, integral tube heat exchanger for tube plate welded flange, catalytic cracking reactor (pressure vessel), cylinder used in hydrogenation reactor, chemical fertilizer equipment required for top cover, bottom cover, head number is forging.

　　按设备重量计算，矿山设备中锻件的比重为百分之十二至百分之二十四。矿山设备有：采掘设备、卷扬设备、破碎设备、研磨设备、洗选设备、烧结设备。

　　According to the weight of equipment, the proportion of forgings in mining equipment is from twelve percent to twenty-four percent. Mining equipment: mining equipment, winding equipment, crushing equipment, grinding equipment, washing equipment, sintering equipment.

　　核电分为压水堆和沸水堆两类。核电站首要的大锻件可分为压力壳和堆内构件两大类。压力壳含：筒体法兰、管嘴段、管嘴、上部筒体、下部筒体、筒体过渡段、螺栓等。堆内构件是在高温、高压、强中子幅照、硼酸水腐蚀、冲刷和水力振荡等严峻条件下工作的，所以要选用18-8奥氏不锈钢来制作。

　　Nuclear power is divided into two categories: pressurized water reactor and boiling water reactor. The main heavy forgings of nuclear power plants can be divided into two major categories: pressure shell and internals. The pressure shell includes: cylinder flange, pipe mouth section, pipe mouth, upper cylinder, lower barrel, tube transition section, bolt and so on. The internals are working under severe conditions such as high temperature, high pressure, strong neutron amplitude, boric acid water corrosion, erosion and hydraulic oscillation, so 18-8 austenitic stainless steel is used.
