鍛件需求每片都是一起的，沒有任何多孔性、剩下空間、內含物或其他的瑕疵。這種辦法出產的元件，強度與重量比有一個高的比率。這些元件通常被用在飛機構造中。鍛件的利益有可拓展的長度、可縮短的橫截面;可縮短的長度、可拓展的橫截面;可改動的長度、可改動的橫截面。你知道環型鍛件加工的技術要求嗎?

　　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?

　　鍛件在石油化工設備中有著廣泛的運用。如球形儲罐的人孔、法蘭，換熱器所需的各種管板、對焊法蘭催化裂化反應器的整鍛筒體(壓力容器)，加氫反應器所用的筒節，化肥設備所需的頂蓋、底蓋、封頭號均是鍛件。

　　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.

　　按設備重量計算，礦山設備中鍛件的比重為百分之十二至百分之二十四。礦山設備有：采掘設備、卷揚設備、破碎設備、研磨設備、洗選設備、燒結設備。

　　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.

　　核電分為壓水堆和沸水堆兩類。核電站首要的大鍛件可分為壓力殼和堆內構件兩大類。壓力殼含：筒體法蘭、管嘴段、管嘴、上部筒體、下部筒體、筒體過渡段、螺栓等。堆內構件是在高溫、高壓、強中子幅照、硼酸水腐蝕、沖刷和水力振蕩等嚴峻條件下工作的，所以要選用18-8奧氏不銹鋼來制作。

　　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.
