　　鑄鐵配重塊是(shi)用(yong)于增(zeng)加自身重量來(lai)保持(chi)平衡的重物(wu)，是(shi)將噴丸機(ji)熔煉成符(fu)合要求的液體(ti)并澆進鑄型里，經冷卻(que)凝固、清整處理(li)后得到有(you)預定(ding)形(xing)狀、尺寸(cun)和性能的鑄件的工(gong)(gong)藝過(guo)程。現(xian)代機(ji)械制造工(gong)(gong)業的基礎工(gong)(gong)藝之一。

　　工(gong)作(zuo)(zuo)面(mian)(mian)(mian)小范(fan)(fan)圍(wei)內的(de)局部變(bian)化是(shi)指加工(gong)表面(mian)(mian)(mian)不平(ping)整，有變(bian)形(xing)，灰口(kou)鐵(tie)(tie)可(ke)以看(kan)作(zuo)(zuo)是(shi)鋼的(de)基體與片狀石(shi)墨的(de)夾雜。因此石(shi)墨片越少，越細，為了(le)保證(zheng)鑄(zhu)(zhu)(zhu)鐵(tie)(tie)在澆(jiao)鑄(zhu)(zhu)(zhu)能夠(gou)得到灰口(kou)，且(qie)不至于得到過多(duo)和粗(cu)大的(de)石(shi)墨片，這里(li)所說的(de)工(gong)作(zuo)(zuo)面(mian)(mian)(mian)小范(fan)(fan)圍(wei)，對小鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)板(ban)而言是(shi)局部位置，對大鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)板(ban)而言是(shi)局部面(mian)(mian)(mian)積(ji)。鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)板(ban)的(de)平(ping)整性反映了(le)鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)板(ban)局部誤差(cha)鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)板(ban)的(de)局部誤差(cha)是(shi)指鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)板(ban)工(gong)作(zuo)(zuo)面(mian)(mian)(mian)局部平(ping)面(mian)(mian)(mian)度加工(gong)質量，即表面(mian)(mian)(mian)粗(cu)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(li)，造(zao)(zao)型(xing)(xing)造(zao)(zao)芯(xin)(xin)都實現了(le)機(ji)(ji)械化(hua)或自動化(hua)。常用的砂(sha)(sha)型(xing)(xing)造(zao)(zao)型(xing)(xing)造(zao)(zao)芯(xin)(xin)設備有高、中、低壓(ya)造(zao)(zao)型(xing)(xing)機(ji)(ji)、拋砂(sha)(sha)機(ji)(ji)、無箱射壓(ya)造(zao)(zao)型(xing)(xing)機(ji)(ji)、射芯(xin)(xin)機(ji)(ji)、冷和熱(re)芯(xin)(xin)盒機(ji)(ji)等。

　　叉車配重鐵(tie)工藝可(ke)分(fen)為三個(ge)基本(ben)部(bu)分(fen)，即配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)金(jin)(jin)屬(shu)(shu)(shu)準備、鑄型(xing)準備和鑄件處理。配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)金(jin)(jin)屬(shu)(shu)(shu)是指配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)生產中用于(yu)澆注鑄件的金(jin)(jin)屬(shu)(shu)(shu)材(cai)(cai)料(liao)，它是以一種金(jin)(jin)屬(shu)(shu)(shu)元(yuan)素為主(zhu)要(yao)成(cheng)(cheng)分(fen)，并加(jia)入(ru)其他(ta)金(jin)(jin)屬(shu)(shu)(shu)或非金(jin)(jin)屬(shu)(shu)(shu)元(yuan)素而組成(cheng)(cheng)的合金(jin)(jin)，習慣上稱為配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)合金(jin)(jin)，主(zhu)要(yao)有(you)鑄鐵(tie)、鑄鋼和配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)有(you)色(se)合金(jin)(jin)。叉(cha)車(che)(che)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)按造(zao)型(xing)材(cai)(cai)料(liao)的不同，又(you)可(ke)分(fen)為兩大類(lei)(lei)：一類(lei)(lei)以天然礦產砂石(shi)作(zuo)為主(zhu)要(yao)造(zao)型(xing)材(cai)(cai)料(liao)，如熔(rong)模配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、殼型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、負壓(ya)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、泥型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、實型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、陶瓷型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)等;一類(lei)(lei)以金(jin)(jin)屬(shu)(shu)(shu)作(zuo)為主(zhu)要(yao)鑄型(xing)材(cai)(cai)料(liao)，如金(jin)(jin)屬(shu)(shu)(shu)型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、離心配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、連續配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、叉(cha)車(che)(che)配(pei)(pei)件鐵(tie)、低壓(ya)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)等。
