济南锻件用料主要是各种成分的碳素钢和合金钢，其次是铝、镁、铜、钛等及其合金。资料的初始状态有棒料、铸锭、金属粉末和液态金属。 金属在变形前的横断面积与变形后的横断面积之比称为锻压比。正确地挑选锻压比、合理的加热温度及保温时刻、合理的始锻温度和终锻温度、合理的变形量及变形速度对进步产品质量、降低成本有很大关系。

　　一般的中小型锻件都用圆形或方形棒料作为坯料。棒料的晶粒安排和机械功能均匀、良好，形状和尺度精确，表面质量好，便于安排批量生产。只需合理操控加热温度和变形条件，不需要大的锻压变形就能锻出功能优秀的锻件。

　　铸锭仅用于大型锻件。铸锭是铸态安排，有较大的柱状晶和疏松的中心。因而有必要通过大的塑性变形，将柱状晶破碎为细晶粒，将疏松压实，才干取得优秀的金属安排和机械功能。

　　经约束和烧结成的粉末冶金预制坯，在热态下经无飞边模锻可制成粉末锻件。锻件粉末接近于一般模锻件的密度，具有良好的机械功能，并且精度高，可减少后续的切削加工。粉末锻件内部安排均匀，没有偏析，可用于制造小型齿轮等工件。但粉末的报价远高于一般棒材的报价，在生产中的使用遭到必定约束。

　　对浇注在模膛的液态金属施加静压力，使其在压力作用下凝结、结晶、活动、塑性变形和成形，就可取得所需形状和功能的模锻件。液态金属模锻是介于压铸和模锻间的成形方法，格外适用于一般模锻难于成形的复杂薄壁件。

　　济南锻件用料除了一般的资料，如各种成分的碳素钢和合金钢，其次是铝、镁、铜、钛等及其合金以外，铁基高温合金，镍基高温合金，钴基高温合金的变形合金也选用锻压或轧制方法完结，只是这些合金由于其塑性区相对较窄，所以锻压难度会相对较大，不一样资料的加热温度，开锻温度与终锻温度都有严厉的需求。

　　中译英：Ji'nan forgings are mainly composed of carbon steel and alloy steel of various components, followed by aluminum, magnesium, copper, titanium and other alloys. The initial state of the material is bar material, ingot, metal powder and liquid metal. The ratio of cross-sectional area before deformation to the cross sectional area after deformation is called forging ratio. The correct selection of forging ratio, reasonable heating temperature and time of heat preservation, reasonable initial forging temperature and final forging temperature, reasonable deformation amount and deformation speed have a great relationship with the quality of the progressive products and the cost reduction.

　　In general, small or medium-sized forgings are made of round or square bar as blank. The bar's grain arrangement and mechanical function are uniform, good, the shape and scale are accurate, the surface quality is good, and it is easy to arrange mass production. Only by reasonably controlling the heating temperature and deformation conditions, we can forge excellent forgings without large forging deformation.

　　Ingots are used only for large forgings. The ingot is cast as cast, with larger columnar grains and loose centers. Therefore, it is necessary to break the columnar crystal into fine grains through large plastic deformation, and to compactness and porosity to achieve excellent metal arrangement and mechanical function.

　　The powder metallurgy precast billets made by binding and sintering can be made into powder forgings without hot flex die forging in hot state. Forgings powder is close to the density of general die forgings. It has good mechanical function and high accuracy, and can reduce subsequent cutting. The powder forgings are evenly arranged without segregation, and can be used for manufacturing small gears and other workpieces. But the price of powder is much higher than that of general bar, and the use in production is bound to be bound.

　　The mold forgings of the desired shape and function can be obtained by applying static pressure to the liquid metal pouring in the mold chamber, so that it condenses, crystallize, activity, plastic deformation and forming under the action of pressure. Liquid metal forging is a forming method between die casting and die forging. It is especially suitable for complex thin-walled parts which are difficult to be formed by general die forging.

　　In addition to general information, such as carbon and alloy steels of various components, and the next of aluminum, magnesium, copper, titanium and their alloys, the deformed alloys of iron base superalloys, nickel based superalloys and cobalt base superalloys have also been completed by forging or rolling methods, but these alloys are relatively narrow because of their plastic zones. Therefore, forging and pressing will be relatively difficult. There is a severe demand for heating temperature, forging temperature and final forging temperature.

　　Ji'nan Spring Heavy Forging Co., Ltd. 18764458888 was established in 1996 as one of the largest manufacturers of forgings in Ji'nan. The main forging, forging, forging and forging factories mainly produce all kinds of die steel, tool steel high speed steel, universal carbon billet and material processing, the maximum single piece production can reach 25 tons.
