鑄造分為哪幾種？

主要有砂型鑄造和特種鑄造2大類(lèi)。

1、普通砂型鑄造，利用砂作為鑄模材料，又稱(chēng)砂鑄，翻砂，包括濕砂型、干砂型和化學(xué)硬化砂型3類(lèi)，但并非所有砂均可用以鑄造。好處是成本較低，因為鑄模所使用的沙可重復使用；缺點(diǎn)是鑄模制作耗時(shí)，鑄模本身不能被重復使用，須破壞后才能取得成品。

2、特種鑄造，按造型材料又可分為以天然礦產(chǎn)砂石為主要造型材料的特種鑄造（如熔模鑄造、泥型鑄造、殼型鑄造、負壓鑄造、實(shí)型鑄造、陶瓷型鑄造等）和以金屬為主要鑄型材料的特種鑄造（如金屬型鑄造、壓力鑄造、連續鑄造、低壓鑄造、離心鑄造等）兩類(lèi)。

鑄造分為哪幾種？

（1）砂型鑄造（sand casting）

砂型鑄造：在砂型中生產(chǎn)鑄件的鑄造方法。鋼、鐵和大多數有色合金鑄件都可用砂型鑄造方法獲得。

技術(shù)特點(diǎn)：

1、適合于制成形狀復雜，特別是具有復雜內腔的毛坯；

2、適應性廣，成本低；

3、對于某些塑性很差的材料，如鑄鐵等，砂型鑄造是制造其零件或，毛坯的唯一的成形工藝。

應用：汽車(chē)的發(fā)動(dòng)機氣缸體、氣缸蓋、曲軸等鑄件

（2）熔模鑄造（investmentcasting）

熔模鑄造：通常是指在易熔材料制成模樣，在模樣表面包覆若干層耐火材料制成型殼，再將模樣熔化排出型殼，從而獲得無(wú)分型面的鑄型，經(jīng)高溫焙燒后即可填砂澆注的鑄造方案。常稱(chēng)為“失蠟鑄造”。

優(yōu)點(diǎn)：

1、尺寸精度和幾何精度高；

2、表面粗糙度高；

3、能夠鑄造外型復雜的鑄件，且鑄造的合金不受限制。

缺點(diǎn)：工序繁雜，費用較高

應用：適用于生產(chǎn)形狀復雜、精度要求高、或很難進(jìn)行其它加工的小型零件，如渦輪發(fā)動(dòng)機的葉片等。

（3）壓力鑄造（die casting）

壓鑄：是利用高壓將金屬液高速壓入一精密金屬模具型腔內，金屬液在壓力作用下冷卻凝固而形成鑄件。

（4）低壓鑄造（low pressure casting）

低壓鑄造：是指使液體金屬在較低壓力(0.02～0.06MPa)作用下充填鑄型，并在壓力下結晶以形成鑄件的方法。

技術(shù)特點(diǎn)：

1、澆注時(shí)的壓力和速度可以調節，故可適用于各種不同鑄型（如金屬型、砂型等），鑄造各種合金及各種大小的鑄件；

2、采用底注式充型，金屬液充型平穩，無(wú)飛濺現象，可避免卷入氣體及對型壁和型芯的沖刷，提高了鑄件的合格率；

3、鑄件在壓力下結晶，鑄件組織致密、輪廓清晰、表面光潔，力學(xué)性能較高，對于大薄壁件的鑄造尤為有利；

4、省去補縮冒口，金屬利用率提高到90%～98%；

5、勞動(dòng)強度低，勞動(dòng)條件好，設備簡(jiǎn)易，易實(shí)現機械化和自動(dòng)化。

應用：以傳統產(chǎn)品為主（氣缸頭、輪轂、氣缸架等）。

（5）離心鑄造(centrifugal casting)

離心鑄造：是將金屬液澆入旋轉的鑄型中，在離心力作用下填充鑄型而凝固成形的一種鑄造方法。

優(yōu)點(diǎn)：

1、幾乎不存在澆注系統和冒口系統的金屬消耗，提高工藝出品率；

2、生產(chǎn)中空鑄件時(shí)可不用型芯，故在生產(chǎn)長(cháng)管形鑄件時(shí)可大幅度地改善金屬充型能力；

3、鑄件致密度高，氣孔、夾渣等缺陷少，力學(xué)性能高；

4、便于制造筒、套類(lèi)復合金屬鑄件。

缺點(diǎn)：

1、用于生產(chǎn)異形鑄件時(shí)有一定的局限性；

2、鑄件內孔直徑不準確，內孔表面比較粗糙，質(zhì)量較差，加工余量大；

3、鑄件易產(chǎn)生比重偏析。

應用：

離心鑄造最早用于生產(chǎn)鑄管，國內外在冶金、礦山、交通、排灌機械、航空、國防、汽車(chē)等行業(yè)中均采用離心鑄造工藝，來(lái)生產(chǎn)鋼、鐵及非鐵碳合金鑄件。其中尤以離心鑄鐵管、內燃機缸套和軸套等鑄件的生產(chǎn)最為普遍。

（6）金屬型鑄造（gravity die casting）

金屬型鑄造：指液態(tài)金屬在重力作用下充填金屬鑄型并在型中冷卻凝固而獲得鑄件的一種成型方法。

優(yōu)點(diǎn):

1、金屬型的熱導率和熱容量大，冷卻速度快，鑄件組織致密，力學(xué)性能比砂型鑄件高15%左右。

2、能獲得較高尺寸精度和較低表面粗糙度值的鑄件，并且質(zhì)量穩定性好。

3、因不用和很少用砂芯，改善環(huán)境、減少粉塵和有害氣體、降低勞動(dòng)強度。

缺點(diǎn)：

1、金屬型本身無(wú)透氣性，必須采用一定的措施導出型腔中的空氣和砂芯所產(chǎn)生的氣體；

2、金屬型無(wú)退讓性，鑄件凝固時(shí)容易產(chǎn)生裂紋；

3、金屬型制造周期較長(cháng)，成本較高。因此只有在大量成批生產(chǎn)時(shí)，才能顯示出好的經(jīng)濟效果。

應用：

金屬型鑄造既適用于大批量生產(chǎn)形狀復雜的鋁合金、鎂合金等非鐵合金鑄件，也適合于生產(chǎn)鋼鐵金屬的鑄件、鑄錠等。

（7）真空壓鑄（vacuumdie casting）

真空鑄造：通過(guò)在壓鑄過(guò)程中抽除壓鑄模具型腔內的氣體而消除或顯著(zhù)減少壓鑄件內的氣孔和溶解氣體，從而提高壓鑄件力學(xué)性能和表面質(zhì)量的先進(jìn)壓鑄工藝。

優(yōu)點(diǎn)：

1、消除或減少壓鑄件內部的氣孔，提高壓鑄件的機械性能和表面質(zhì)量，改善鍍覆性能；

2、減少型腔的反壓力，可使用較低的比壓及鑄造性能較差的合金，有可能用小機器壓鑄較大的鑄件；

3、改善了充填條件，可壓鑄較薄的鑄件。

缺點(diǎn)：

1、模具密封結構復雜，制造及安裝較困難，因而成本較高；

2、 真空壓鑄法如控制不當，效果就不是很顯著(zhù)。

（8）擠壓鑄造（squeezing die casting）

擠壓鑄造：是使液態(tài)或半固態(tài)金屬在高壓下凝固、流動(dòng)成形，直接獲得制件或毛坯的方法。它具有液態(tài)金屬利用率高、工序簡(jiǎn)化和質(zhì)量穩定等優(yōu)點(diǎn)，是一種節能型的、具有潛在應用前景的金屬成形技術(shù)。

（9）消失模鑄造（Lost foam casting）

消失模鑄造（又稱(chēng)實(shí)型鑄造）：是將與鑄件尺寸形狀相似的石蠟或泡沫模型粘結組合成模型簇，刷涂耐火涂料并烘干后，埋在干石英砂中振動(dòng)造型，在負壓下澆注，使模型氣化，液體金屬占據模型位置，凝固冷卻后形成鑄件的新型鑄造方法。

技術(shù)特點(diǎn)：

1、鑄件精度高，無(wú)砂芯，減少了加工時(shí)間；

2、無(wú)分型面，設計靈活，自由度高；

3、清潔生產(chǎn)，無(wú)污染；

4、降低投資和生產(chǎn)成本。

應用：

適合成產(chǎn)結構復雜的各種大小較精密鑄件，合金種類(lèi)不限，生產(chǎn)批量不限。如灰鑄鐵發(fā)動(dòng)機箱體、高錳鋼彎管等。

（10）連續鑄造（continual casting）

連續鑄造：是一種先進(jìn)的鑄造方法，其原理是將熔融的金屬，不斷澆入一種叫做結晶器的特殊金屬型中，凝固（結殼）了的鑄件，連續不斷地從結晶器的另一端拉出，它可獲得任意長(cháng)或特定的長(cháng)度的鑄件。
