　　鑄鐵配重塊是(shi)用于增加(jia)自身重(zhong)量來保持平衡的(de)(de)(de)重(zhong)物，是(shi)將噴丸機熔煉(lian)成符(fu)合要求的(de)(de)(de)液(ye)體并(bing)澆進(jin)鑄型里，經冷卻凝固、清整處理(li)后得到有預定形(xing)狀、尺寸和性能(neng)的(de)(de)(de)鑄件的(de)(de)(de)工(gong)藝過(guo)程(cheng)。現代(dai)機械制造工(gong)業的(de)(de)(de)基礎工(gong)藝之一。

　　工(gong)(gong)作面(mian)(mian)(mian)小范圍內的(de)局(ju)部(bu)變化是(shi)(shi)指加工(gong)(gong)表面(mian)(mian)(mian)不平(ping)整(zheng)，有變形，灰口(kou)鐵(tie)(tie)(tie)(tie)可以看作是(shi)(shi)鋼的(de)基體(ti)與片(pian)狀(zhuang)石墨(mo)的(de)夾雜。因此(ci)石墨(mo)片(pian)越少，越細，為了保證鑄鐵(tie)(tie)(tie)(tie)在(zai)澆(jiao)鑄能夠得(de)到灰口(kou)，且不至于(yu)得(de)到過(guo)多和粗大(da)的(de)石墨(mo)片(pian)，這里所說的(de)工(gong)(gong)作面(mian)(mian)(mian)小范圍，對(dui)小鑄鐵(tie)(tie)(tie)(tie)平(ping)板(ban)(ban)(ban)而言(yan)是(shi)(shi)局(ju)部(bu)位置(zhi)，對(dui)大(da)鑄鐵(tie)(tie)(tie)(tie)平(ping)板(ban)(ban)(ban)而言(yan)是(shi)(shi)局(ju)部(bu)面(mian)(mian)(mian)積。鑄鐵(tie)(tie)(tie)(tie)平(ping)板(ban)(ban)(ban)的(de)平(ping)整(zheng)性反映了鑄鐵(tie)(tie)(tie)(tie)平(ping)板(ban)(ban)(ban)局(ju)部(bu)誤差鑄鐵(tie)(tie)(tie)(tie)平(ping)板(ban)(ban)(ban)的(de)局(ju)部(bu)誤差是(shi)(shi)指鑄鐵(tie)(tie)(tie)(tie)平(ping)板(ban)(ban)(ban)工(gong)(gong)作面(mian)(mian)(mian)局(ju)部(bu)平(ping)面(mian)(mian)(mian)度加工(gong)(gong)質量，即(ji)表面(mian)(mian)(mian)粗糙度。

　　鑄件的精度和生產過程的經濟表現，主要取決于這道工序。在很多現代化的配重鐵車間里，造(zao)型造(zao)芯都實現了機(ji)械化或自動化。常用(yong)的砂(sha)(sha)型造(zao)型造(zao)芯設(she)備有(you)高(gao)、中(zhong)、低(di)壓造(zao)型機(ji)、拋砂(sha)(sha)機(ji)、無(wu)箱射壓造(zao)型機(ji)、射芯機(ji)、冷和熱(re)芯盒機(ji)等。

　　叉車配重鐵(tie)(tie)工藝可(ke)分(fen)(fen)為(wei)(wei)(wei)三個基(ji)本部分(fen)(fen)，即配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金屬(shu)(shu)(shu)(shu)(shu)準備(bei)、鑄型(xing)(xing)(xing)(xing)準備(bei)和(he)鑄件(jian)(jian)處理。配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金屬(shu)(shu)(shu)(shu)(shu)是指配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)生產(chan)中用于澆注鑄件(jian)(jian)的(de)金屬(shu)(shu)(shu)(shu)(shu)材(cai)料，它(ta)是以一種(zhong)金屬(shu)(shu)(shu)(shu)(shu)元素(su)為(wei)(wei)(wei)主(zhu)要成分(fen)(fen)，并加入其他金屬(shu)(shu)(shu)(shu)(shu)或非金屬(shu)(shu)(shu)(shu)(shu)元素(su)而組(zu)成的(de)合(he)金，習慣上稱(cheng)為(wei)(wei)(wei)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)合(he)金，主(zhu)要有鑄鐵(tie)(tie)、鑄鋼和(he)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)有色合(he)金。叉(cha)車配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)按造型(xing)(xing)(xing)(xing)材(cai)料的(de)不同，又(you)可(ke)分(fen)(fen)為(wei)(wei)(wei)兩大類：一類以天(tian)然礦(kuang)產(chan)砂石作(zuo)為(wei)(wei)(wei)主(zhu)要造型(xing)(xing)(xing)(xing)材(cai)料，如熔模配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、殼型(xing)(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、負壓(ya)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、泥型(xing)(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、實型(xing)(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、陶瓷型(xing)(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等;一類以金屬(shu)(shu)(shu)(shu)(shu)作(zuo)為(wei)(wei)(wei)主(zhu)要鑄型(xing)(xing)(xing)(xing)材(cai)料，如金屬(shu)(shu)(shu)(shu)(shu)型(xing)(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、離(li)心配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、連續配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、叉(cha)車配(pei)(pei)(pei)件(jian)(jian)鐵(tie)(tie)、低壓(ya)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等。
