配重鐵是現代機(ji)械(xie)制造(zao)工(gong)業(ye)的(de)基礎(chu)工(gong)藝之一，是用于增加自身(shen)重量來保持平衡的(de)重物，是將噴丸機(ji)熔煉成符(fu)合   要求的(de)液體并(bing)澆進鑄(zhu)型(xing)里，經(jing)冷卻凝固、清整處理后有(you)預定(ding)形(xing)狀、尺寸和性能的(de)鑄(zhu)件的(de)工(gong)藝過程。

配(pei)重鐵(tie)分為重工業(ye)配(pei)重鐵(tie)和(he)輕工業(ye)配(pei)重鐵(tie)：

重(zhong)(zhong)(zhong)(zhong)工業(ye)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)一(yi)(yi)般按造(zao)型(xing)(xing)(xing)方法來分(fen)類(lei)，習慣上分(fen)為(wei)(wei)(wei)普通砂型(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)和特重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)。普通砂型(xing)(xing)(xing)配(pei)(pei)(pei)種配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)包括濕砂型(xing)(xing)(xing)、干砂型(xing)(xing)(xing)、化學硬化砂型(xing)(xing)(xing)三類(lei)。特種配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)按造(zao)型(xing)(xing)(xing)材(cai)(cai)料的不同，又可分(fen)為(wei)(wei)(wei)兩大(da)類(lei)：一(yi)(yi)類(lei)以(yi)   礦產砂石作為(wei)(wei)(wei)主(zhu)要造(zao)型(xing)(xing)(xing)材(cai)(cai)料，如熔模配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)、殼型(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)、負壓(ya)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)、泥型(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)、實型(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)、陶瓷型(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)等；一(yi)(yi)類(lei)以(yi)金(jin)屬作為(wei)(wei)(wei)主(zhu)要鑄型(xing)(xing)(xing)材(cai)(cai)料，如金(jin)屬型(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)、離心配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)、連續配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)、壓(ya)力(li)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)、低壓(ya)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)等。 重(zhong)(zhong)(zhong)(zhong)工業(ye)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)工藝可分(fen)為(wei)(wei)(wei)三個基本部分(fen)，即配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)金(jin)屬準備、鑄型(xing)(xing)(xing)準備和鑄件(jian)處理(li)。

輕工業(ye)配重鐵(tie)(tie)分(fen)類(lei)(lei)沒(mei)有明確的界定(ding)，大(da)致也可以分(fen)為兩(liang)大(da)類(lei)(lei)。一(yi)類(lei)(lei)為板(ban)材(cai)加(jia)工成型(xing)；一(yi)類(lei)(lei)為型(xing)材(cai)加(jia)工成型(xing)。材(cai)料主(zhu)要包括(kuo)各種(zhong)板(ban)材(cai)、片材(cai)、圓鐵(tie)(tie)、扁鐵(tie)(tie)、方鐵(tie)(tie)、其(qi)它型(xing)材(cai)等(deng)。

輕重(zhong)(zhong)工(gong)業配(pei)(pei)重(zhong)(zhong)鐵(tie)(tie)可(ke)以用(yong)于不同(tong)的不同(tong)產品上(shang)面做配(pei)(pei)件，充分起到了增(zeng)(zeng)加重(zhong)(zhong)量(liang)(liang)和保持平衡(heng)的作用(yong)。配(pei)(pei)重(zhong)(zhong)鐵(tie)(tie)應(ying)用(yong)在大型機械設備上(shang)同(tong)時也廣泛應(ying)用(yong)于各個行業里，比如用(yong)在工(gong)程機械中(zhong)，例如挖(wa)掘機配(pei)(pei)重(zhong)(zhong)鐵(tie)(tie)、叉(cha)車配(pei)(pei)重(zhong)(zhong)鐵(tie)(tie)、裝載(zai)機配(pei)(pei)重(zhong)(zhong)鐵(tie)(tie)、起重(zhong)(zhong)機配(pei)(pei)重(zhong)(zhong)鐵(tie)(tie)；一(yi)般拉貨的拖拉機，貨物過沉，要在車頭或車尾放入配(pei)(pei)重(zhong)(zhong)鐵(tie)(tie)來提高輪胎(tai)的摩擦力進而增(zeng)(zeng)加牽引力。我們日常使用(yong)的固定電話聽(ting)筒里也都普(pu)遍使用(yong)配(pei)(pei)重(zhong)(zhong)鐵(tie)(tie)來增(zeng)(zeng)加手(shou)感重(zhong)(zhong)量(liang)(liang)等等。
