Vakum Furnace Quenching I No Stret Long Putum long Furnace Mo i Kamaotem Mo i Stap Kamdaon.

Em i no ol samting i gat bikpela pe olsem i as bilong hevi, tasol ol rabis wokmansip-defomesen, kreking, i no wankain hat. Wanpela lain samting tasol inap kostim planti handet tausen yuan, tasol wanpela samting ol i no skelim gut inap bagarapim olgeta samting. Moa yet taim ol i yusim ol 'vacuum furnaces' bilong kilim i dai, planti papa bilong haus i ting olsem wanpela klinpela envairomen na stretpela tempereja em olgeta samting ol i nidim. Tasol taim ol hap i kamap long paia, pes i luk olsem i lait, tasol taim ol i glasim, ol i soim olsem i no gat inap hat, ol liklik samting i no stret, na ol krek i stap long ples tu... Wanem hevi? Inap tru, pasin bilong daunim 'vacuum quenching' i luk olsem wanpela isipela wok: hatim → holim → quenching, tasol wanwan step i gat ol trap bilong en. Sapos yu no was gut liklik inap bagarapim olgeta wok bilong yu bilong . 1. pasin bilong Lodim ol samting i save givim stretpela samting long yunifomiti bilong yu. Planti manmeri, kisim isi rot bilong lusim, bungim tasol wanpela basket bilong ol hap na subim ol i go insait. Tasol yu bin tingim: olsem wanem ol i tilim win i ron? I no gat wok long mekim kol i min olsem tempereja long sedo eria i go daun isi isi, na as maikrostraksa i go insait long transfomesen i no gutpela olgeta, na dispela i mekim na i no gat strong. Stretpela rot: Lusim bikpela spes namel long ol hap bilong abrusim pasin bilong no inap bruk; Putum ol longfala pat long senta mo ol sot pat aotbod blong mekem sua se ea i ron raon long evri kona; Mekem trei long stret fasin blong no blokem dak blong mekem man i kolkol. Dispela em i no samting bilong laik; em i wanpela proses rikwaemen. 2. Noken bihainim tumas wanpela hariap hat reit. Long wanpela vekim, i no gat konveksen; hat trensfe i save kamap olgeta long rot bilong rediesen. Sapos tempereja i go antap hariap tumas, moa yet wantaim tik-}wal pat o hai-alloy stiel, tempereja bilong pes i kamap hat taim insait i stap kol i stap kol-} dispela ol i save olsem "termal stres," we inap isi long kamapim krek long taim bilong kilim i dai. Rekomendasen: Long ol mol stiel olsem Cr12MoV na H13, o bilong ol bikpela wokpis, givim ol step bilong holim namel (olsem, 800 digri inap 30 minit) long larim ol tempereja insait na ausait i wankain. Hitim gut na no ken kalapim ol step. Go slou em i sef moa =. 3. Kensing na kol: em i bikpela samting tru na em i save feil tru. Planti ol 'vacuum furnace' i save yusim 'high-}li naitrojen o argon bilong presurized quenching, wantaim ol presa i save stat long 0.6–2.0 MPa. Tasol planti fektori i lukluk tasol long setpoint, i no trupela pefomens. Ol Problem blong ol Komon: Fasin blong stap klin long ges i no inaf, oksijen o wetwet konten i afektem kolkol spid mo kwaliti blong fes blong hem; Nosel blok o daunim fan efisiensi i save kamapim kol i no wankain; No gat step-by-pesen presa kontrol, we i kamapim bikpela presa long stat, inap kamapim hap defomesen. Ol tip: Oltaim sekim ges dew poin bilong lukim olsem yu drai; Jekem kondisen blong fan mo nosel bifo yu quenching; Long ol kompleks wokpis, ol i ken yusim wanpela "stej presaisasen" mod: pre-}kulim long liklik presa pastaim long apim presa long pinisim fez transisen. 4. Noken wet longpela taim tumas long rausim wokpis long furnace. Taim ol i stopim pinis dispela paia, planti manmeri i no save hariap long rausim ol hap, na ol i ting olsem "longpela liklik taim bai mekim wok." Tasol, ol vekim oven i gat gutpela insulet, na ol hap i save kol isi isi insait, na inap winim gutpela pre- pilim temperaja, na dispela i daunim wok bilong tempering bihain. Wanem samting i bikpela moa em olsem sampela martensitik straksa i save stap long liklik tempereja zon inap longpela taim tumas na ol i save kisim bagarap.
