鑄鐵配重塊是用于增加自身重(zhong)量來保持平衡的(de)(de)重(zhong)物，是將(jiang)噴丸機熔煉成符合 要求的(de)(de)液體并澆進(jin)鑄型里，經冷卻凝(ning)固(gu)、清整(zheng)處理后得(de)到有預定形狀(zhuang)、尺寸(cun)和性(xing)能的(de)(de)鑄件(jian)的(de)(de)工(gong)(gong)藝過(guo)程(cheng)。現代(dai)機械制(zhi)造(zao)工(gong)(gong)業的(de)(de)基礎(chu)工(gong)(gong)藝之一(yi)。
工作(zuo)面(mian)(mian)(mian)(mian)小范圍內的(de)(de)局(ju)部(bu)變化(hua)是指(zhi)加工表面(mian)(mian)(mian)(mian)不平(ping)(ping)(ping)整，有變形(xing)，灰口鐵(tie)(tie)可(ke)以看(kan)作(zuo)是鋼(gang)的(de)(de)基體與片(pian)(pian)(pian)狀(zhuang)石(shi)墨(mo)的(de)(de)夾雜(za)。因此(ci)石(shi)墨(mo)片(pian)(pian)(pian)越少，越細，為了(le)保證鑄(zhu)(zhu)(zhu)鐵(tie)(tie)在(zai)澆鑄(zhu)(zhu)(zhu)能夠(gou)得到灰口，且不至于得到過多和粗大(da)(da)的(de)(de)石(shi)墨(mo)片(pian)(pian)(pian)，這(zhe)里所說的(de)(de)工作(zuo)面(mian)(mian)(mian)(mian)小范圍，對小鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)(ping)(ping)板而言(yan)是局(ju)部(bu)位置，對大(da)(da)鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)(ping)(ping)板而言(yan)是局(ju)部(bu)面(mian)(mian)(mian)(mian)積。鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)(ping)(ping)板的(de)(de)平(ping)(ping)(ping)整性反映了(le)鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)(ping)(ping)板局(ju)部(bu)誤差鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)(ping)(ping)板的(de)(de)局(ju)部(bu)誤差是指(zhi)鑄(zhu)(zhu)(zhu)鐵(tie)(tie)平(ping)(ping)(ping)板工作(zuo)面(mian)(mian)(mian)(mian)局(ju)部(bu)平(ping)(ping)(ping)面(mian)(mian)(mian)(mian)度加工質量，即表面(mian)(mian)(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(zao)型造(zao)芯都(dou)實(shi)現了機械化(hua)或自動化(hua)。常(chang)用的(de)砂(sha)型造(zao)型造(zao)芯設備有高、中、低壓造(zao)型機、拋砂(sha)機、無(wu)箱射壓造(zao)型機、射芯機、冷和熱芯盒機等。
叉車配重鐵(tie)(tie)(tie)(tie)(tie)工藝可(ke)分為(wei)(wei)(wei)三個基本部(bu)分，即配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)金(jin)屬準備、鑄(zhu)(zhu)型(xing)(xing)準備和鑄(zhu)(zhu)件(jian)處理。 配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)金(jin)屬是指配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)生產中用于澆(jiao)注鑄(zhu)(zhu)件(jian)的金(jin)屬材料，它是以一種金(jin)屬元(yuan)素為(wei)(wei)(wei)主要成(cheng)分，并(bing)加(jia)入其他金(jin)屬或非金(jin)屬元(yuan)素而(er)組成(cheng)的合金(jin)，習慣上稱(cheng)為(wei)(wei)(wei)配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)合金(jin)，主要有(you)鑄(zhu)(zhu)鐵(tie)(tie)(tie)(tie)(tie)、鑄(zhu)(zhu)鋼和配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)有(you)色合金(jin)。叉車配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)按造(zao)型(xing)(xing)材料的不同，又可(ke)分為(wei)(wei)(wei)兩大類：一類以天(tian)然礦產砂石作(zuo)為(wei)(wei)(wei)主要造(zao)型(xing)(xing)材料，如(ru)熔模配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、殼型(xing)(xing)配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、負壓配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、泥型(xing)(xing)配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、實型(xing)(xing)配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、陶瓷(ci)型(xing)(xing)配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)等;一類以金(jin)屬作(zuo)為(wei)(wei)(wei)主要鑄(zhu)(zhu)型(xing)(xing)材料，如(ru)金(jin)屬型(xing)(xing)配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、離心配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、連續配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、叉車配件(jian)鐵(tie)(tie)(tie)(tie)(tie)、低(di)壓配重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)等。
