鑄鐵配重塊是(shi)用于增加自(zi)身(shen)重(zhong)量(liang)來保持平(ping)衡的重(zhong)物，是(shi)將噴丸機熔煉(lian)成(cheng)符(fu)合(he) 要求的液體并澆進鑄型里，經(jing)冷卻凝固、清(qing)整處理(li)后(hou)得(de)到有預(yu)定形狀(zhuang)、尺寸和性能的鑄件的工藝過程(cheng)。現(xian)代機械制(zhi)造工業的基礎工藝之一。
工(gong)作(zuo)(zuo)面(mian)(mian)小(xiao)范(fan)(fan)圍內(nei)的(de)局部(bu)變化是(shi)(shi)指加(jia)工(gong)表面(mian)(mian)不(bu)平(ping)(ping)(ping)整，有變形(xing)，灰(hui)口鐵(tie)(tie)(tie)可以看作(zuo)(zuo)是(shi)(shi)鋼的(de)基體與片狀石墨(mo)的(de)夾雜。因此石墨(mo)片越少，越細，為了(le)(le)保證鑄(zhu)鐵(tie)(tie)(tie)在(zai)澆(jiao)鑄(zhu)能(neng)夠(gou)得到灰(hui)口，且不(bu)至于得到過多和粗大(da)(da)的(de)石墨(mo)片，這里所說的(de)工(gong)作(zuo)(zuo)面(mian)(mian)小(xiao)范(fan)(fan)圍，對(dui)小(xiao)鑄(zhu)鐵(tie)(tie)(tie)平(ping)(ping)(ping)板(ban)(ban)而言是(shi)(shi)局部(bu)位置，對(dui)大(da)(da)鑄(zhu)鐵(tie)(tie)(tie)平(ping)(ping)(ping)板(ban)(ban)而言是(shi)(shi)局部(bu)面(mian)(mian)積。鑄(zhu)鐵(tie)(tie)(tie)平(ping)(ping)(ping)板(ban)(ban)的(de)平(ping)(ping)(ping)整性反映了(le)(le)鑄(zhu)鐵(tie)(tie)(tie)平(ping)(ping)(ping)板(ban)(ban)局部(bu)誤差鑄(zhu)鐵(tie)(tie)(tie)平(ping)(ping)(ping)板(ban)(ban)的(de)局部(bu)誤差是(shi)(shi)指鑄(zhu)鐵(tie)(tie)(tie)平(ping)(ping)(ping)板(ban)(ban)工(gong)作(zuo)(zuo)面(mian)(mian)局部(bu)平(ping)(ping)(ping)面(mian)(mian)度加(jia)工(gong)質量，即表面(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(jian)里，造型(xing)造芯(xin)都實現(xian)了(le)機(ji)械化或(huo)自(zi)動化。常用的砂型(xing)造型(xing)造芯(xin)設備有高、中、低壓(ya)造型(xing)機(ji)、拋(pao)砂機(ji)、無箱射(she)壓(ya)造型(xing)機(ji)、射(she)芯(xin)機(ji)、冷和熱芯(xin)盒機(ji)等。
叉車配重鐵(tie)(tie)工藝(yi)可分(fen)為(wei)(wei)三個基(ji)本部分(fen)，即配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)屬(shu)(shu)準(zhun)備、鑄型準(zhun)備和鑄件處理。 配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)屬(shu)(shu)是指配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)生產中(zhong)用(yong)于澆注鑄件的金(jin)屬(shu)(shu)材(cai)料，它是以(yi)(yi)一(yi)(yi)種金(jin)屬(shu)(shu)元素為(wei)(wei)主(zhu)要(yao)成分(fen)，并加入其(qi)他金(jin)屬(shu)(shu)或非金(jin)屬(shu)(shu)元素而組成的合金(jin)，習慣上稱為(wei)(wei)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)合金(jin)，主(zhu)要(yao)有(you)鑄鐵(tie)(tie)、鑄鋼和配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)有(you)色合金(jin)。叉(cha)車配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)按(an)造型材(cai)料的不同，又(you)可分(fen)為(wei)(wei)兩大類：一(yi)(yi)類以(yi)(yi)天(tian)然礦產砂石作(zuo)為(wei)(wei)主(zhu)要(yao)造型材(cai)料，如熔模配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、殼型配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、負壓配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、泥型配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、實型配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、陶瓷型配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等(deng);一(yi)(yi)類以(yi)(yi)金(jin)屬(shu)(shu)作(zuo)為(wei)(wei)主(zhu)要(yao)鑄型材(cai)料，如金(jin)屬(shu)(shu)型配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、離心配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、連續配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、叉(cha)車配(pei)件鐵(tie)(tie)、低壓配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等(deng)。
