詳(xiang)細介紹：

　　鑄鐵配重塊是用于增加自(zi)身(shen)重(zhong)量來保(bao)持(chi)平衡(heng)的(de)重(zhong)物，是將噴丸機熔(rong)煉成符合要求的(de)液(ye)體并澆(jiao)進鑄(zhu)型里，經冷(leng)卻凝固、清整(zheng)處理后得到有預定形狀、尺寸(cun)和性能的(de)鑄(zhu)件的(de)工(gong)(gong)藝過(guo)程。現代機械制造工(gong)(gong)業的(de)基礎(chu)工(gong)(gong)藝之一。

　　工(gong)(gong)作(zuo)面(mian)小(xiao)范(fan)圍內的局(ju)部(bu)(bu)變(bian)化是(shi)(shi)指加工(gong)(gong)表面(mian)不平(ping)(ping)整(zheng)，有變(bian)形，灰(hui)口鐵可(ke)以(yi)看作(zuo)是(shi)(shi)鋼(gang)的基體與片狀(zhuang)石墨的夾雜。因(yin)此石墨片越少，越細(xi)，為了(le)保證鑄(zhu)鐵在澆鑄(zhu)能(neng)夠得到(dao)灰(hui)口，且不至于得到(dao)過多和粗(cu)大的石墨片，這里(li)所說的工(gong)(gong)作(zuo)面(mian)小(xiao)范(fan)圍，對小(xiao)鑄(zhu)鐵平(ping)(ping)板而言(yan)是(shi)(shi)局(ju)部(bu)(bu)位置，對大鑄(zhu)鐵平(ping)(ping)板而言(yan)是(shi)(shi)局(ju)部(bu)(bu)面(mian)積。鑄(zhu)鐵平(ping)(ping)板的平(ping)(ping)整(zheng)性反映了(le)鑄(zhu)鐵平(ping)(ping)板局(ju)部(bu)(bu)誤(wu)差鑄(zhu)鐵平(ping)(ping)板的局(ju)部(bu)(bu)誤(wu)差是(shi)(shi)指鑄(zhu)鐵平(ping)(ping)板工(gong)(gong)作(zuo)面(mian)局(ju)部(bu)(bu)平(ping)(ping)面(mian)度(du)加工(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(li)，造(zao)(zao)(zao)型(xing)(xing)(xing)造(zao)(zao)(zao)芯都實現了機(ji)械化(hua)或自(zi)動化(hua)。常用的砂型(xing)(xing)(xing)造(zao)(zao)(zao)型(xing)(xing)(xing)造(zao)(zao)(zao)芯設(she)備有高、中、低壓造(zao)(zao)(zao)型(xing)(xing)(xing)機(ji)、拋砂機(ji)、無箱射壓造(zao)(zao)(zao)型(xing)(xing)(xing)機(ji)、射芯機(ji)、冷和(he)熱芯盒(he)機(ji)等。

　　叉車配重鐵(tie)(tie)工藝可分(fen)為(wei)(wei)三個基本部分(fen)，即配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)準備、鑄(zhu)型(xing)準備和鑄(zhu)件(jian)處理。配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)是(shi)指配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)生產(chan)中用于澆注(zhu)鑄(zhu)件(jian)的(de)金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)材(cai)(cai)料(liao)，它是(shi)以一(yi)種金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)元(yuan)素為(wei)(wei)主(zhu)要(yao)成分(fen)，并加入(ru)其他金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)或非金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)元(yuan)素而(er)組(zu)成的(de)合(he)金(jin)(jin)(jin)(jin)，習(xi)慣上稱為(wei)(wei)配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)合(he)金(jin)(jin)(jin)(jin)，主(zhu)要(yao)有鑄(zhu)鐵(tie)(tie)、鑄(zhu)鋼(gang)和配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)有色(se)合(he)金(jin)(jin)(jin)(jin)。叉(cha)車(che)配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)按造(zao)型(xing)材(cai)(cai)料(liao)的(de)不同，又可分(fen)為(wei)(wei)兩大類(lei)：一(yi)類(lei)以天然礦產(chan)砂石作為(wei)(wei)主(zhu)要(yao)造(zao)型(xing)材(cai)(cai)料(liao)，如(ru)(ru)熔模配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)、殼型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)、負壓配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)、泥型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)、實型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)、陶瓷型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)等;一(yi)類(lei)以金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)作為(wei)(wei)主(zhu)要(yao)鑄(zhu)型(xing)材(cai)(cai)料(liao)，如(ru)(ru)金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)、離心(xin)配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)、連續配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)、叉(cha)車(che)配(pei)(pei)件(jian)鐵(tie)(tie)、低壓配(pei)(pei)重(zhong)(zhong)(zhong)鐵(tie)(tie)等。
