鑄鐵配重塊是用于增加自身重(zhong)量來保持平衡的重(zhong)物(wu)，是將噴丸機熔煉成(cheng)符合 要求(qiu)的液體并(bing)澆進鑄(zhu)型里，經冷卻凝固、清整處(chu)理后得到有預定形狀、尺(chi)寸和(he)性能的鑄(zhu)件的工(gong)(gong)藝(yi)(yi)過程。現代機械制造工(gong)(gong)業的基礎工(gong)(gong)藝(yi)(yi)之一。
工作(zuo)面(mian)(mian)小范圍(wei)內的局(ju)部(bu)(bu)變化是(shi)指加工表面(mian)(mian)不平(ping)(ping)(ping)整，有(you)變形，灰口鐵可以看作(zuo)是(shi)鋼的基體與片(pian)狀石墨的夾雜。因此石墨片(pian)越少，越細，為了保證鑄(zhu)(zhu)鐵在澆鑄(zhu)(zhu)能夠得到灰口，且(qie)不至于得到過多(duo)和粗大的石墨片(pian)，這里(li)所說的工作(zuo)面(mian)(mian)小范圍(wei)，對小鑄(zhu)(zhu)鐵平(ping)(ping)(ping)板(ban)而言是(shi)局(ju)部(bu)(bu)位置，對大鑄(zhu)(zhu)鐵平(ping)(ping)(ping)板(ban)而言是(shi)局(ju)部(bu)(bu)面(mian)(mian)積。鑄(zhu)(zhu)鐵平(ping)(ping)(ping)板(ban)的平(ping)(ping)(ping)整性反映了鑄(zhu)(zhu)鐵平(ping)(ping)(ping)板(ban)局(ju)部(bu)(bu)誤(wu)差(cha)鑄(zhu)(zhu)鐵平(ping)(ping)(ping)板(ban)的局(ju)部(bu)(bu)誤(wu)差(cha)是(shi)指鑄(zhu)(zhu)鐵平(ping)(ping)(ping)板(ban)工作(zuo)面(mian)(mian)局(ju)部(bu)(bu)平(ping)(ping)(ping)面(mian)(mian)度(du)(du)加工質量，即表面(mian)(mian)粗糙(cao)度(du)(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，造型(xing)(xing)造芯(xin)(xin)(xin)都實現了機(ji)(ji)械化或自動化。常(chang)用的砂型(xing)(xing)造型(xing)(xing)造芯(xin)(xin)(xin)設備有(you)高(gao)、中、低壓造型(xing)(xing)機(ji)(ji)、拋砂機(ji)(ji)、無箱(xiang)射(she)壓造型(xing)(xing)機(ji)(ji)、射(she)芯(xin)(xin)(xin)機(ji)(ji)、冷(leng)和熱芯(xin)(xin)(xin)盒機(ji)(ji)等(deng)。
叉車配重鐵(tie)工藝可分(fen)為(wei)三個基本部分(fen)，即配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)金(jin)(jin)屬(shu)(shu)準備(bei)、鑄型(xing)(xing)準備(bei)和鑄件(jian)處(chu)理。 配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)金(jin)(jin)屬(shu)(shu)是指配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)生產(chan)中(zhong)用于澆注鑄件(jian)的金(jin)(jin)屬(shu)(shu)材(cai)(cai)(cai)料(liao)，它是以(yi)一(yi)種金(jin)(jin)屬(shu)(shu)元(yuan)素為(wei)主要(yao)成分(fen)，并加入其他金(jin)(jin)屬(shu)(shu)或(huo)非金(jin)(jin)屬(shu)(shu)元(yuan)素而組(zu)成的合(he)金(jin)(jin)，習慣(guan)上稱為(wei)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)合(he)金(jin)(jin)，主要(yao)有鑄鐵(tie)、鑄鋼(gang)和配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)有色合(he)金(jin)(jin)。叉(cha)車配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)按(an)造型(xing)(xing)材(cai)(cai)(cai)料(liao)的不同(tong)，又可分(fen)為(wei)兩大(da)類：一(yi)類以(yi)天然礦產(chan)砂石作為(wei)主要(yao)造型(xing)(xing)材(cai)(cai)(cai)料(liao)，如熔模配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、殼(ke)型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、負(fu)壓配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、泥(ni)型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、實(shi)型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、陶瓷型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)等;一(yi)類以(yi)金(jin)(jin)屬(shu)(shu)作為(wei)主要(yao)鑄型(xing)(xing)材(cai)(cai)(cai)料(liao)，如金(jin)(jin)屬(shu)(shu)型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、離心配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、連續配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、叉(cha)車配(pei)件(jian)鐵(tie)、低壓配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)等。
