詳細介(jie)紹：

　　鑄鐵配重塊是(shi)用于增加自(zi)身重量來(lai)保持平衡(heng)的(de)(de)(de)重物，是(shi)將噴(pen)丸機(ji)熔(rong)煉成符合要求的(de)(de)(de)液體并澆進鑄(zhu)型里，經冷卻凝固、清(qing)整處(chu)理(li)后(hou)得到(dao)有預定形狀、尺寸(cun)和(he)性能的(de)(de)(de)鑄(zhu)件的(de)(de)(de)工(gong)藝過程。現代機(ji)械制造工(gong)業的(de)(de)(de)基礎(chu)工(gong)藝之一。

　　工(gong)作面(mian)小范圍內的(de)(de)局(ju)(ju)部(bu)(bu)(bu)(bu)變化是指加工(gong)表面(mian)不(bu)平(ping)(ping)(ping)整(zheng)，有變形，灰口鐵可以(yi)看(kan)作是鋼的(de)(de)基體與片狀石墨的(de)(de)夾雜。因(yin)此石墨片越少，越細(xi)，為了(le)保證鑄(zhu)(zhu)鐵在(zai)澆(jiao)鑄(zhu)(zhu)能(neng)夠得(de)到灰口，且不(bu)至(zhi)于(yu)得(de)到過多(duo)和粗大(da)的(de)(de)石墨片，這里(li)所說的(de)(de)工(gong)作面(mian)小范圍，對小鑄(zhu)(zhu)鐵平(ping)(ping)(ping)板(ban)而(er)言是局(ju)(ju)部(bu)(bu)(bu)(bu)位(wei)置(zhi)，對大(da)鑄(zhu)(zhu)鐵平(ping)(ping)(ping)板(ban)而(er)言是局(ju)(ju)部(bu)(bu)(bu)(bu)面(mian)積。鑄(zhu)(zhu)鐵平(ping)(ping)(ping)板(ban)的(de)(de)平(ping)(ping)(ping)整(zheng)性反映了(le)鑄(zhu)(zhu)鐵平(ping)(ping)(ping)板(ban)局(ju)(ju)部(bu)(bu)(bu)(bu)誤(wu)差鑄(zhu)(zhu)鐵平(ping)(ping)(ping)板(ban)的(de)(de)局(ju)(ju)部(bu)(bu)(bu)(bu)誤(wu)差是指鑄(zhu)(zhu)鐵平(ping)(ping)(ping)板(ban)工(gong)作面(mian)局(ju)(ju)部(bu)(bu)(bu)(bu)平(ping)(ping)(ping)面(mian)度(du)加工(gong)質量，即表面(mian)粗糙度(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)型(xing)造(zao)(zao)芯都實現了(le)機(ji)(ji)械化(hua)或自動化(hua)。常用的砂(sha)型(xing)造(zao)(zao)型(xing)造(zao)(zao)芯設備有高、中(zhong)、低壓造(zao)(zao)型(xing)機(ji)(ji)、拋砂(sha)機(ji)(ji)、無箱(xiang)射壓造(zao)(zao)型(xing)機(ji)(ji)、射芯機(ji)(ji)、冷和熱芯盒機(ji)(ji)等。

　　叉車配重鐵(tie)(tie)工藝(yi)可分(fen)為(wei)三個基本部分(fen)，即配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)屬準備、鑄(zhu)(zhu)型(xing)(xing)準備和鑄(zhu)(zhu)件處理。配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)屬是指(zhi)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)生(sheng)產中用于澆(jiao)注鑄(zhu)(zhu)件的金(jin)屬材(cai)料，它是以(yi)一種(zhong)金(jin)屬元素為(wei)主(zhu)要(yao)成分(fen)，并加入其他金(jin)屬或非金(jin)屬元素而組成的合金(jin)，習慣上(shang)稱為(wei)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)合金(jin)，主(zhu)要(yao)有(you)鑄(zhu)(zhu)鐵(tie)(tie)、鑄(zhu)(zhu)鋼(gang)和配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)有(you)色合金(jin)。叉車(che)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)按造型(xing)(xing)材(cai)料的不同，又可分(fen)為(wei)兩大類(lei)：一類(lei)以(yi)天(tian)然礦產砂石作為(wei)主(zhu)要(yao)造型(xing)(xing)材(cai)料，如熔模配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、殼型(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、負壓(ya)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、泥型(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、實(shi)型(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、陶瓷型(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等;一類(lei)以(yi)金(jin)屬作為(wei)主(zhu)要(yao)鑄(zhu)(zhu)型(xing)(xing)材(cai)料，如金(jin)屬型(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、離心配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、連續配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、叉車(che)配(pei)(pei)(pei)件鐵(tie)(tie)、低壓(ya)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等。
