大家(jia)(jia)好(hao)本期小(xiao)編給大家(jia)(jia)帶來(lai)新的(de)內容(rong)，希望(wang)對大家(jia)(jia)有所幫(bang)助(zhu)：鍛件批發價格(ge)

提(ti)高筒類鍛(duan)件表面質(zhi)量的措施？

筒(tong)類(lei)鍛(duan)件(jian)(jian)是(shi)壓(ya)力容器中重要的(de)組(zu)成部分，筒(tong)節(jie)質(zhi)量(liang)的(de)好壞(huai)直接關系到整臺反應器的(de)好壞(huai)。由于筒(tong)節(jie)大部分都需(xu)要鐓(dui)粗(cu)沖孔(kong)、芯棒拔(ba)長、擴孔(kong)等工(gong)序 ，所以在生產過程中容易出(chu)現飛邊、折傷(shang)、橢(tuo)圓等質(zhi)量(liang)問題(ti)而導致(zhi)鍛(duan)件(jian)(jian)報廢。本文(wen)結(jie)合筒(tong)類(lei)鍛(duan)件(jian)(jian)的(de)生產工(gong)序分析總結(jie)了(le)筒(tong)類(lei)鍛(duan)件(jian)(jian)的(de)幾種(zhong)質(zhi)量(liang)問題(ti)，針對這(zhe)幾種(zhong)質(zhi)量(liang)問題(ti)提出(chu)了(le)解(jie)決方案以及預(yu)防措施。

筒類鍛件的(de)幾種(zhong)質量問題

通過長期的生(sheng)產跟蹤，筒類鍛件(jian)容易出現以下幾種質(zhi)量問題：

(1) 內(nei)外(wai)表面(mian)出現凹(ao)坑、折(zhe)傷；

(2) 端(duan)面長(chang)短不(bu)齊(qi)、壁厚不(bu)均(jun)勻；

(3) 筒(tong)節端面出現折傷以及飛(fei)邊開裂、飛(fei)邊折疊進入(ru)筒(tong)身內部；

(4) 出成品后(hou)橢圓度較大。

鍛(duan)(duan)造鍛(duan)(duan)件時(shi)常見的低(di)倍缺陷有哪些？

殘(can)余(yu)(yu)縮(suo)(suo)孔(kong)(kong)是(shi)鋼材中不(bu)允許的(de)(de)(de)冶金缺(que)(que)陷(xian)。因為殘(can)余(yu)(yu)縮(suo)(suo)孔(kong)(kong)是(shi)夾(jia)雜和(he)氣體聚集的(de)(de)(de)地(di)方，在(zai)進一步熱(re)加工中往往擴展成裂紋，破壞(huai)了(le)鋼材的(de)(de)(de)連(lian)續(xu)性。在(zai)澆鑄鋼錠(ding)時(shi)采取措施，使縮(suo)(suo)孔(kong)(kong)集中在(zai)鋼錠(ding)冒口(kou)部位，并且在(zai)鑄錠(ding)開坯(pi)時(shi)保(bao)證足夠的(de)(de)(de)切頭(tou)率，即(ji)可避免鋼材上的(de)(de)(de)殘(can)余(yu)(yu)縮(suo)(suo)孔(kong)(kong)缺(que)(que)陷(xian)。 

鑄錠內部(bu)通常是不致(zhi)密的(de)，湖南(nan)鍛(duan)件批發價格，往往存在著很(hen)多(duo)因(yin)收縮(suo)或其他原因(yin)而(er)引起的(de)細小孔隙，稱為疏(shu)(shu)松(song)(song)(song)(song)。疏(shu)(shu)松(song)(song)(song)(song)多(duo)位于鋼(gang)錠的(de)上部(bu)和中(zhong)(zhong)部(bu)，縮(suo)孔附近常存在較(jiao)多(duo)疏(shu)(shu)松(song)(song)(song)(song)。鋼(gang)材(cai)在熱加工過程中(zhong)(zhong)，疏(shu)(shu)松(song)(song)(song)(song)可得(de)到很(hen)大程度的(de)改善；但若原鋼(gang)錠的(de)疏(shu)(shu)松(song)(song)(song)(song)較(jiao)為嚴重、壓縮(suo)比不足，則在熱加工后疏(shu)(shu)松(song)(song)(song)(song)還會(hui)存在。鋼(gang)材(cai)中(zhong)(zhong)如存在疏(shu)(shu)松(song)(song)(song)(song)，會(hui)降(jiang)低其力學性(xing)能，特別是塑性(xing)

鍛(duan)件(jian)缺陷與(yu)材料特(te)性不同而引起的超聲波變化。

通過(guo)分析超聲波(bo)(bo)在介質中的(de)(de)傳播特(te)性以(yi)及大型(xing)鍛件內部缺(que)陷(xian)的(de)(de)聲學(xue)特(te)性可知，各種(zhong)缺(que)陷(xian)的(de)(de)邊(bian)界(jie)特(te)性均可歸(gui)納為(wei)兩大類(lei):裂紋、白點、縮孔、氣(qi)泡、非金屬夾(jia)(jia)雜物的(de)(de)邊(bian)界(jie)屬于“軟”邊(bian)界(jie)，超聲波(bo)(bo)垂直入射(she)(she)在這(zhe)種(zhong)界(jie)面(mian)(mian)上時反射(she)(she)回波(bo)(bo)的(de)(de)相(xiang)位(wei)(wei)改(gai)變180度;高密(mi)度金屬夾(jia)(jia)雜物的(de)(de)邊(bian)界(jie)屬于“硬”邊(bian)界(jie)，超聲波(bo)(bo)垂直入射(she)(she)在這(zhe)種(zhong)界(jie)面(mian)(mian)上時其反射(she)(she)回波(bo)(bo)的(de)(de)相(xiang)位(wei)(wei)與(yu)入射(she)(she)波(bo)(bo)相(xiang)位(wei)(wei)相(xiang)同(tong)。

對于裂(lie)紋(wen)、白(bai)點、縮孔(kong)、氣泡以及非(fei)金屬夾雜物，盡管其(qi)聲(sheng)阻(zu)(zu)抗(kang)不相(xiang)同，但都可以通過式( 1)和式( 2)計算(suan)出其(qi)反射(she)率(lv)和透射(she)率(lv)，這2個參數(shu)反映了(le)超聲(sheng)回波(bo)(bo)信號的幅度衰減(jian)(jian)水平。非(fei)金屬夾雜物與基(ji)體組織的聲(sheng)阻(zu)(zu)抗(kang)差(cha)異小，透射(she)率(lv)高，因(yin)此其(qi)回波(bo)(bo)衰減(jian)(jian)非(fei)常(chang)嚴(yan)重，表(biao)現(xian)為檢測(ce)時(shi)底波(bo)(bo)幅度小甚(shen)至沒有底波(bo)(bo);白(bai)點反射(she)波(bo)(bo)很強，但由(you)(you)于其(qi)成(cheng)群(qun)出現(xian)，故(gu)(gu)在檢測(ce)時(shi)波(bo)(bo)形表(biao)現(xian)為缺陷信號清晰(xi)而群(qun)集(ji);裂(lie)紋(wen)缺陷的反射(she)波(bo)(bo)強烈且(qie)單一存在，非(fei)常(chang)清晰(xi);縮孔(kong)缺陷由(you)(you)于其(qi)周圍有大量夾雜物，同時(shi)其(qi)表(biao)面非(fei)常(chang)粗(cu)糙(cao)，故(gu)(gu)反射(she)波(bo)(bo)會(hui)產生(sheng)了(le)較大的衰減(jian)(jian)。
