濟(jì)南鍛件用料主要是各種成分的碳素鋼和合金鋼，其次是鋁、鎂、銅、鈦等及其合金。資料的初始狀態(tài)有棒料、鑄錠、金屬粉末和液態(tài)金屬。 金屬在變形前的橫斷面積與變形后的橫斷面積之比稱(chēng)為鍛壓比。正確地挑選鍛壓比、合理的加熱溫度及保溫時(shí)刻、合理的始鍛溫度和終鍛溫度、合理的變形量及變形速度對(duì)進(jìn)步產(chǎn)品質(zhì)量、降低成本有很大關(guān)系。

　　一般的中小型鍛件都用圓形或方形棒料作為坯料。棒料的晶粒安排和機(jī)械功能均勻、良好，形狀和尺度精確，表面質(zhì)量好，便于安排批量生產(chǎn)。只需合理操控加熱溫度和變形條件，不需要大的鍛壓變形就能鍛出功能優(yōu)秀的鍛件。

　　鑄錠僅用于大型鍛件。鑄錠是鑄態(tài)安排，有較大的柱狀晶和疏松的中心。因而有必要通過(guò)大的塑性變形，將柱狀晶破碎為細(xì)晶粒，將疏松壓實(shí)，才干取得優(yōu)秀的金屬安排和機(jī)械功能。

　　經(jīng)約束和燒結(jié)成的粉末冶金預(yù)制坯，在熱態(tài)下經(jīng)無(wú)飛邊模鍛可制成粉末鍛件。鍛件粉末接近于一般模鍛件的密度，具有良好的機(jī)械功能，并且精度高，可減少后續(xù)的切削加工。粉末鍛件內(nèi)部安排均勻，沒(méi)有偏析，可用于制造小型齒輪等工件。但粉末的報(bào)價(jià)遠(yuǎn)高于一般棒材的報(bào)價(jià)，在生產(chǎn)中的使用遭到必定約束。

　　對(duì)澆注在模膛的液態(tài)金屬施加靜壓力，使其在壓力作用下凝結(jié)、結(jié)晶、活動(dòng)、塑性變形和成形，就可取得所需形狀和功能的模鍛件。液態(tài)金屬模鍛是介于壓鑄和模鍛間的成形方法，格外適用于一般模鍛難于成形的復(fù)雜薄壁件。

　　濟(jì)南鍛件用料除了一般的資料，如各種成分的碳素鋼和合金鋼，其次是鋁、鎂、銅、鈦等及其合金以外，鐵基高溫合金，鎳基高溫合金，鈷基高溫合金的變形合金也選用鍛壓或軋制方法完結(jié)，只是這些合金由于其塑性區(qū)相對(duì)較窄，所以鍛壓難度會(huì)相對(duì)較大，不一樣資料的加熱溫度，開(kāi)鍛溫度與終鍛溫度都有嚴(yán)厲的需求。

　　濟(jì)南泉西重型鍛造有限公司18764458888成立于1996年是濟(jì)南較大的鍛件生產(chǎn)廠家之一,主營(yíng)鍛造,鍛造加工,鍛件廠.主要生產(chǎn)各種模具鋼、工具鋼高速鋼、普碳鋼坯及來(lái)料加工,最大單件生產(chǎn)量可達(dá)25噸.

　　中譯英：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.
