　　鑄鐵配重塊是(shi)用于(yu)增加(jia)自身重量來保(bao)持平衡的重物(wu)，是(shi)將噴(pen)丸機熔煉(lian)成符(fu)合(he) 要求(qiu)的液體并澆進鑄型里，經冷卻(que)凝固、清整處理后得(de)到有預(yu)定形狀、尺寸和性能的鑄件的工(gong)藝(yi)過(guo)程。現代機械制(zhi)造工(gong)業的基礎(chu)工(gong)藝(yi)之一。

　　工(gong)(gong)作面(mian)(mian)小范圍(wei)內的(de)(de)局(ju)部(bu)(bu)變(bian)化(hua)是(shi)指(zhi)加工(gong)(gong)表(biao)面(mian)(mian)不平(ping)(ping)(ping)(ping)整(zheng)，有變(bian)形(xing)，灰口鐵(tie)可以看作是(shi)鋼的(de)(de)基體與片(pian)狀石(shi)(shi)墨(mo)的(de)(de)夾雜。因(yin)此石(shi)(shi)墨(mo)片(pian)越(yue)少(shao)，越(yue)細，為(wei)了保(bao)證鑄(zhu)(zhu)鐵(tie)在澆鑄(zhu)(zhu)能夠(gou)得到(dao)灰口，且不至(zhi)于得到(dao)過多和粗大的(de)(de)石(shi)(shi)墨(mo)片(pian)，這里所說(shuo)的(de)(de)工(gong)(gong)作面(mian)(mian)小范圍(wei)，對小鑄(zhu)(zhu)鐵(tie)平(ping)(ping)(ping)(ping)板(ban)(ban)而(er)言(yan)是(shi)局(ju)部(bu)(bu)位(wei)置(zhi)，對大鑄(zhu)(zhu)鐵(tie)平(ping)(ping)(ping)(ping)板(ban)(ban)而(er)言(yan)是(shi)局(ju)部(bu)(bu)面(mian)(mian)積(ji)。鑄(zhu)(zhu)鐵(tie)平(ping)(ping)(ping)(ping)板(ban)(ban)的(de)(de)平(ping)(ping)(ping)(ping)整(zheng)性反(fan)映了鑄(zhu)(zhu)鐵(tie)平(ping)(ping)(ping)(ping)板(ban)(ban)局(ju)部(bu)(bu)誤差鑄(zhu)(zhu)鐵(tie)平(ping)(ping)(ping)(ping)板(ban)(ban)的(de)(de)局(ju)部(bu)(bu)誤差是(shi)指(zhi)鑄(zhu)(zhu)鐵(tie)平(ping)(ping)(ping)(ping)板(ban)(ban)工(gong)(gong)作面(mian)(mian)局(ju)部(bu)(bu)平(ping)(ping)(ping)(ping)面(mian)(mian)度加工(gong)(gong)質量，即表(biao)面(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(xing)(xing)造(zao)芯(xin)都實(shi)現(xian)了機械化(hua)或自動化(hua)。常用(yong)的砂型(xing)(xing)造(zao)型(xing)(xing)造(zao)芯(xin)設備有(you)高、中、低(di)壓造(zao)型(xing)(xing)機、拋砂機、無箱射壓造(zao)型(xing)(xing)機、射芯(xin)機、冷(leng)和熱芯(xin)盒機等。

　　叉車配重鐵(tie)(tie)(tie)(tie)(tie)工(gong)藝可分(fen)(fen)為三個基本部分(fen)(fen)，即配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)金(jin)(jin)屬(shu)準備(bei)、鑄(zhu)型(xing)準備(bei)和(he)鑄(zhu)件處理。配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)金(jin)(jin)屬(shu)是指配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)生產中用于澆注鑄(zhu)件的(de)金(jin)(jin)屬(shu)材(cai)料，它(ta)是以(yi)一種(zhong)金(jin)(jin)屬(shu)元(yuan)素(su)為主(zhu)要成分(fen)(fen)，并(bing)加(jia)入其他金(jin)(jin)屬(shu)或非金(jin)(jin)屬(shu)元(yuan)素(su)而(er)組(zu)成的(de)合(he)金(jin)(jin)，習慣上稱為配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)合(he)金(jin)(jin)，主(zhu)要有鑄(zhu)鐵(tie)(tie)(tie)(tie)(tie)、鑄(zhu)鋼和(he)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)有色合(he)金(jin)(jin)。叉(cha)車配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)按(an)造型(xing)材(cai)料的(de)不(bu)同，又可分(fen)(fen)為兩(liang)大類：一類以(yi)天然礦產砂石(shi)作為主(zhu)要造型(xing)材(cai)料，如熔(rong)模配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、殼型(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、負壓配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、泥(ni)型(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、實型(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、陶瓷型(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)等;一類以(yi)金(jin)(jin)屬(shu)作為主(zhu)要鑄(zhu)型(xing)材(cai)料，如金(jin)(jin)屬(shu)型(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、離心配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、連(lian)續配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、叉(cha)車配(pei)(pei)(pei)(pei)件鐵(tie)(tie)(tie)(tie)(tie)、低壓配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)等。
