鑄鐵配重塊是用于增(zeng)加自身(shen)重(zhong)量來保持平衡的重(zhong)物，是將(jiang)噴丸機(ji)熔煉成符合 要求的液體并澆進(jin)鑄(zhu)型里，經冷(leng)卻凝固、清整(zheng)處理后(hou)得(de)到有(you)預定形狀、尺寸(cun)和性能的鑄(zhu)件的工(gong)藝過程。現代機(ji)械制造工(gong)業(ye)的基礎工(gong)藝之一。
工(gong)(gong)作面(mian)小(xiao)范圍(wei)內的局(ju)部(bu)變(bian)化是指加(jia)工(gong)(gong)表面(mian)不平(ping)整(zheng)，有變(bian)形(xing)，灰(hui)口鐵(tie)(tie)(tie)可(ke)以看作是鋼(gang)的基體(ti)與(yu)片狀石墨(mo)的夾雜。因(yin)此石墨(mo)片越少，越細，為了保(bao)證鑄(zhu)鐵(tie)(tie)(tie)在澆鑄(zhu)能夠(gou)得(de)到灰(hui)口，且(qie)不至于得(de)到過多和粗(cu)大的石墨(mo)片，這(zhe)里所說的工(gong)(gong)作面(mian)小(xiao)范圍(wei)，對(dui)小(xiao)鑄(zhu)鐵(tie)(tie)(tie)平(ping)板(ban)(ban)(ban)而言(yan)是局(ju)部(bu)位置，對(dui)大鑄(zhu)鐵(tie)(tie)(tie)平(ping)板(ban)(ban)(ban)而言(yan)是局(ju)部(bu)面(mian)積。鑄(zhu)鐵(tie)(tie)(tie)平(ping)板(ban)(ban)(ban)的平(ping)整(zheng)性反映了鑄(zhu)鐵(tie)(tie)(tie)平(ping)板(ban)(ban)(ban)局(ju)部(bu)誤差鑄(zhu)鐵(tie)(tie)(tie)平(ping)板(ban)(ban)(ban)的局(ju)部(bu)誤差是指鑄(zhu)鐵(tie)(tie)(tie)平(ping)板(ban)(ban)(ban)工(gong)(gong)作面(mian)局(ju)部(bu)平(ping)面(mian)度(du)加(jia)工(gong)(gong)質量，即表面(mian)粗(cu)糙度(du)。
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)(zao)型(xing)造(zao)(zao)芯都實現了機(ji)(ji)械化(hua)或(huo)自動化(hua)。常用的(de)砂型(xing)造(zao)(zao)型(xing)造(zao)(zao)芯設(she)備(bei)有(you)高(gao)、中、低(di)壓(ya)造(zao)(zao)型(xing)機(ji)(ji)、拋砂機(ji)(ji)、無箱射壓(ya)造(zao)(zao)型(xing)機(ji)(ji)、射芯機(ji)(ji)、冷和熱芯盒機(ji)(ji)等。
叉車配重鐵(tie)(tie)(tie)工藝(yi)可分為三個(ge)基本部分，即配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)金(jin)(jin)屬準(zhun)(zhun)備(bei)、鑄型(xing)(xing)準(zhun)(zhun)備(bei)和(he)(he)鑄件處理。 配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)金(jin)(jin)屬是指配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)生產(chan)(chan)中用(yong)于澆注鑄件的金(jin)(jin)屬材料(liao)(liao)，它(ta)是以(yi)一種金(jin)(jin)屬元素為主要成(cheng)分，并加入其他金(jin)(jin)屬或非金(jin)(jin)屬元素而組成(cheng)的合金(jin)(jin)，習慣上稱(cheng)為配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)合金(jin)(jin)，主要有鑄鐵(tie)(tie)(tie)、鑄鋼和(he)(he)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)有色(se)合金(jin)(jin)。叉車配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)按造型(xing)(xing)材料(liao)(liao)的不同，又可分為兩(liang)大類(lei)：一類(lei)以(yi)天(tian)然礦(kuang)產(chan)(chan)砂石作為主要造型(xing)(xing)材料(liao)(liao)，如(ru)熔模配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、殼型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、負壓配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、泥型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、實(shi)型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、陶瓷型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)等(deng);一類(lei)以(yi)金(jin)(jin)屬作為主要鑄型(xing)(xing)材料(liao)(liao)，如(ru)金(jin)(jin)屬型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、離心配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、連續(xu)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、叉車配(pei)件鐵(tie)(tie)(tie)、低壓配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)等(deng)。
