清理鑄件

去(qu)除(chu)型(xing)砂(sha)：對于(yu)采(cai)用(yong)(yong)(yong)(yong)(yong)砂(sha)型(xing)鑄(zhu)造的(de)不銹鋼鑄(zhu)件，首(shou)先要(yao)(yao)去(qu)除(chu)表(biao)面的(de)型(xing)砂(sha)。可使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)振(zhen)(zhen)動(dong)(dong)落(luo)(luo)砂(sha)機，通過(guo)振(zhen)(zhen)動(dong)(dong)使(shi)(shi)(shi)型(xing)砂(sha)脫落(luo)(luo)。對于(yu)一(yi)(yi)些復雜形狀或附著較(jiao)(jiao)牢的(de)型(xing)砂(sha)部分，可能(neng)還需(xu)要(yao)(yao)借助風鏟、砂(sha)輪等工具進(jin)行(xing)清(qing)理。切(qie)除(chu)澆冒口(kou)：澆冒口(kou)是在鑄(zhu)造過(guo)程中用(yong)(yong)(yong)(yong)(yong)于(yu)澆注金屬液和(he)補縮的(de)部分，在鑄(zhu)件凝(ning)固后(hou)(hou)需(xu)要(yao)(yao)切(qie)除(chu)。可以使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)切(qie)割鋸(ju)(ju)、氣(qi)割等方法。如對于(yu)小型(xing)不銹鋼鑄(zhu)件，使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)高速切(qie)割鋸(ju)(ju)能(neng)保證切(qie)口(kou)較(jiao)(jiao)平整；對于(yu)較(jiao)(jiao)大(da)的(de)鑄(zhu)件，氧 - 乙炔氣(qi)割比較(jiao)(jiao)常用(yong)(yong)(yong)(yong)(yong)，但氣(qi)割后(hou)(hou)可能(neng)需(xu)要(yao)(yao)進(jin)一(yi)(yi)步打磨(mo)處(chu)理切(qie)口(kou)。清(qing)理毛(mao)刺和(he)飛(fei)邊：鑄(zhu)件表(biao)面的(de)毛(mao)刺和(he)飛(fei)邊會影(ying)響其外觀(guan)和(he)尺寸精(jing)度。可以用(yong)(yong)(yong)(yong)(yong)砂(sha)輪機、銼刀等工具進(jin)行(xing)打磨(mo)清(qing)理。對于(yu)一(yi)(yi)些精(jing)細部位(wei)，使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)小型(xing)手(shou)持(chi)電(dian)動(dong)(dong)工具進(jin)行(xing)精(jing)細打磨(mo)，以獲得光(guang)滑的(de)表(biao)面。

熱處理

固溶處(chu)理：目的(de)(de)是(shi)使不(bu)銹(xiu)鋼(gang)中的(de)(de)碳(tan)化物等合金元素溶解在(zai)(zai)奧氏(shi)體中。通常將鑄(zhu)(zhu)件(jian)(jian)(jian)加熱到(dao) 1050 - 1150℃（不(bu)同不(bu)銹(xiu)鋼(gang)型號溫度略有差異），保(bao)持一(yi)定時(shi)(shi)(shi)間(jian)后迅速冷卻，一(yi)般(ban)是(shi)水冷。例如(ru)，304 不(bu)銹(xiu)鋼(gang)鑄(zhu)(zhu)件(jian)(jian)(jian)在(zai)(zai)經過固溶處(chu)理后，能夠提(ti)高其耐腐(fu)蝕性(xing)和韌(ren)性(xing)。時(shi)(shi)(shi)效處(chu)理：一(yi)些沉淀硬(ying)化型不(bu)銹(xiu)鋼(gang)鑄(zhu)(zhu)件(jian)(jian)(jian)需要(yao)進行(xing)時(shi)(shi)(shi)效處(chu)理，以析(xi)出強(qiang)化相，提(ti)高鑄(zhu)(zhu)件(jian)(jian)(jian)的(de)(de)強(qiang)度和硬(ying)度。在(zai)(zai)較(jiao)低溫度（一(yi)般(ban) 400 - 600℃）下(xia)長(chang)時(shi)(shi)(shi)間(jian)保(bao)溫，使合金中的(de)(de)第二相沉淀析(xi)出，如(ru) 17 - 4PH 不(bu)銹(xiu)鋼(gang)鑄(zhu)(zhu)件(jian)(jian)(jian)經過時(shi)(shi)(shi)效處(chu)理后，其機械性(xing)能會(hui)得到(dao)顯著改善。

表面處理

拋(pao)(pao)光(guang)處理(li)(li)(li)(li)：機械拋(pao)(pao)光(guang)：利用(yong)拋(pao)(pao)光(guang)輪和拋(pao)(pao)光(guang)膏(gao)對(dui)鑄(zhu)(zhu)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)進行打(da)磨，使表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)達(da)到光(guang)亮的(de)(de)(de)(de)(de)。拋(pao)(pao)光(guang)輪一(yi)般(ban)采用(yong)布輪、氈輪等軟性(xing)材料，拋(pao)(pao)光(guang)膏(gao)根據鑄(zhu)(zhu)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)要(yao)求(qiu)選擇不(bu)同粒度和成(cheng)分的(de)(de)(de)(de)(de)產品。例如(ru)(ru)，對(dui)于要(yao)求(qiu)高鏡面(mian)(mian)(mian)(mian)光(guang)澤的(de)(de)(de)(de)(de)不(bu)銹鋼(gang)裝(zhuang)飾(shi)鑄(zhu)(zhu)件(jian)(jian)(jian)，需要(yao)經過(guo)(guo)(guo)多道精細(xi)的(de)(de)(de)(de)(de)機械拋(pao)(pao)光(guang)工序。電解(jie)(jie)拋(pao)(pao)光(guang)：以鑄(zhu)(zhu)件(jian)(jian)(jian)為(wei)陽極，在(zai)特(te)定的(de)(de)(de)(de)(de)電解(jie)(jie)液(ye)(ye)中通過(guo)(guo)(guo)電解(jie)(jie)作用(yong)，使鑄(zhu)(zhu)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)微觀凸起部分溶(rong)解(jie)(jie)，從而(er)獲得平整光(guang)亮的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)。這種方法適合處理(li)(li)(li)(li)形(xing)狀復雜的(de)(de)(de)(de)(de)不(bu)銹鋼(gang)鑄(zhu)(zhu)件(jian)(jian)(jian)，并且(qie)能夠有效去(qu)除(chu)(chu)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)的(de)(de)(de)(de)(de)微小瑕疵。鈍化(hua)(hua)處理(li)(li)(li)(li)：將不(bu)銹鋼(gang)鑄(zhu)(zhu)件(jian)(jian)(jian)浸泡(pao)在(zai)鈍化(hua)(hua)液(ye)(ye)（如(ru)(ru)硝(xiao)酸、檸(ning)檬酸等溶(rong)液(ye)(ye)）中，使鑄(zhu)(zhu)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)形(xing)成(cheng)一(yi)層致(zhi)密的(de)(de)(de)(de)(de)鈍化(hua)(hua)膜，增(zeng)(zeng)強其耐(nai)腐蝕性(xing)。例如(ru)(ru)，316 不(bu)銹鋼(gang)鑄(zhu)(zhu)件(jian)(jian)(jian)經過(guo)(guo)(guo)鈍化(hua)(hua)處理(li)(li)(li)(li)后，在(zai)一(yi)些腐蝕性(xing)環境(jing)（如(ru)(ru)海洋環境(jing)）中的(de)(de)(de)(de)(de)抗腐蝕能力提高。噴砂處理(li)(li)(li)(li)：通過(guo)(guo)(guo)壓縮(suo)空(kong)氣將磨料（如(ru)(ru)石英砂、剛玉砂等）高速噴射(she)到鑄(zhu)(zhu)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)，去(qu)除(chu)(chu)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)的(de)(de)(de)(de)(de)氧(yang)化(hua)(hua)皮、污垢(gou)等，同時可以使鑄(zhu)(zhu)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)獲得均勻的(de)(de)(de)(de)(de)粗糙度，用(yong)于一(yi)些需要(yao)增(zeng)(zeng)加涂層附著力或者有特(te)殊質感要(yao)求(qiu)的(de)(de)(de)(de)(de)鑄(zhu)(zhu)件(jian)(jian)(jian)。
