詳細介紹：

　　鑄鐵配重塊是用于增(zeng)加自(zi)身重(zhong)量來保持平衡的(de)重(zhong)物(wu)，是將(jiang)噴丸機熔煉(lian)成(cheng)符(fu)合要求的(de)液體并澆進鑄(zhu)型里，經冷卻凝固、清整處理(li)后得到有(you)預定形狀、尺寸和性能的(de)鑄(zhu)件的(de)工藝(yi)過(guo)程。現代機械制(zhi)造(zao)工業(ye)的(de)基礎工藝(yi)之一(yi)。

　　工(gong)(gong)作(zuo)(zuo)面(mian)小范圍內的(de)(de)局(ju)部(bu)變(bian)化(hua)是(shi)指(zhi)加工(gong)(gong)表(biao)面(mian)不平(ping)(ping)整(zheng)(zheng)，有變(bian)形，灰口(kou)鐵(tie)(tie)可以(yi)看作(zuo)(zuo)是(shi)鋼的(de)(de)基體與片(pian)(pian)狀石墨的(de)(de)夾雜。因(yin)此石墨片(pian)(pian)越(yue)少，越(yue)細，為了保證鑄(zhu)鐵(tie)(tie)在澆鑄(zhu)能夠得到灰口(kou)，且不至于得到過多和(he)粗(cu)大(da)的(de)(de)石墨片(pian)(pian)，這里所說的(de)(de)工(gong)(gong)作(zuo)(zuo)面(mian)小范圍，對(dui)小鑄(zhu)鐵(tie)(tie)平(ping)(ping)板(ban)(ban)而言是(shi)局(ju)部(bu)位置，對(dui)大(da)鑄(zhu)鐵(tie)(tie)平(ping)(ping)板(ban)(ban)而言是(shi)局(ju)部(bu)面(mian)積。鑄(zhu)鐵(tie)(tie)平(ping)(ping)板(ban)(ban)的(de)(de)平(ping)(ping)整(zheng)(zheng)性反映了鑄(zhu)鐵(tie)(tie)平(ping)(ping)板(ban)(ban)局(ju)部(bu)誤(wu)(wu)差鑄(zhu)鐵(tie)(tie)平(ping)(ping)板(ban)(ban)的(de)(de)局(ju)部(bu)誤(wu)(wu)差是(shi)指(zhi)鑄(zhu)鐵(tie)(tie)平(ping)(ping)板(ban)(ban)工(gong)(gong)作(zuo)(zuo)面(mian)局(ju)部(bu)平(ping)(ping)面(mian)度加工(gong)(gong)質(zhi)量，即表(biao)面(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(che)間里，造(zao)(zao)(zao)型造(zao)(zao)(zao)芯(xin)都實現了機械化或自動化。常用的砂型造(zao)(zao)(zao)型造(zao)(zao)(zao)芯(xin)設備有(you)高、中、低(di)壓造(zao)(zao)(zao)型機、拋(pao)砂機、無(wu)箱射(she)壓造(zao)(zao)(zao)型機、射(she)芯(xin)機、冷和熱芯(xin)盒機等。

　　叉車配重鐵(tie)(tie)工藝可(ke)分為三個基本(ben)部分，即配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)屬(shu)(shu)(shu)準(zhun)備(bei)、鑄(zhu)(zhu)型(xing)(xing)(xing)準(zhun)備(bei)和鑄(zhu)(zhu)件(jian)處(chu)理。配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)屬(shu)(shu)(shu)是(shi)(shi)指(zhi)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)生產(chan)(chan)中(zhong)用于澆注鑄(zhu)(zhu)件(jian)的(de)金(jin)(jin)屬(shu)(shu)(shu)材料，它是(shi)(shi)以(yi)一(yi)種金(jin)(jin)屬(shu)(shu)(shu)元素(su)為主要成分，并加入(ru)其(qi)他金(jin)(jin)屬(shu)(shu)(shu)或非(fei)金(jin)(jin)屬(shu)(shu)(shu)元素(su)而(er)組成的(de)合金(jin)(jin)，習慣上稱為配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)合金(jin)(jin)，主要有鑄(zhu)(zhu)鐵(tie)(tie)、鑄(zhu)(zhu)鋼和配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)有色合金(jin)(jin)。叉車配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)按(an)造(zao)型(xing)(xing)(xing)材料的(de)不同，又(you)可(ke)分為兩(liang)大類：一(yi)類以(yi)天然礦產(chan)(chan)砂石作為主要造(zao)型(xing)(xing)(xing)材料，如熔模配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、殼型(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、負壓配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、泥型(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、實型(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、陶瓷型(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等(deng);一(yi)類以(yi)金(jin)(jin)屬(shu)(shu)(shu)作為主要鑄(zhu)(zhu)型(xing)(xing)(xing)材料，如金(jin)(jin)屬(shu)(shu)(shu)型(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、離心配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、連(lian)續配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、叉車配(pei)(pei)件(jian)鐵(tie)(tie)、低壓配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等(deng)。
