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 mekim 'quenching', planti papa bilong haus i ting olsem wanpela klinpela envairomen na stretpela temperaja em olgeta samting we yu 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 i no gat ol liklik hap bilong en 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 lukaut gut, dispela inap bagarapim olgeta wok bilong yu.
1. Loading rot i save givim stretpela impak long yunifomiti.
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 planti spes namel long ol hap bilong abrusim pasin bilong pas gut;
Putum ol longfala pat long senta mo ol sot pat aotsaed longbod blong mekem sua se ea i ron raon long evri kona;
Putum ol hol long trei long stret fasin blong blokem blong blokem kolkol dak.
Dispela em i no wanpela kain samting; em i wanpela proses rikwaemen.
2. Noken bihainim tumas mak bilong hatim hariap.
Long wanpela vekim, i no gat konveksen; hat trensfe em i long rediesen olgeta. Sapos temperaja i go antap hariap tumas, moa yet long tik-}wal pat o hai-alloy stiel, tempereja bilong pes i kamap hat taim insait i stap kol i stap kol- dispela ol i kolim "temal stres," we inap isi long kamapim krek long taim bilong quenching.
Rekomendasen:
Long ol mol stiel olsem Cr12MoV na H13, o 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.
Sloa hat i tru moa seif.
3. Quenching: Kenja we i kritikal mo i save feil.
Planti ol 'vacuum furnace' i save yusim 'high-'purity naitrogen o 'argon' bilong 'texing quenching', we i save kamap namel long 0.6 na 2.0 MPa. Tasol planti fektori i lukluk tasol long ol set veliu, i no ol risal tru.
Ol Hevi:
I no gat inap ges klin, oksijen o wara i stap insait long en, na dispela i bagarapim spit bilong kol na kwaliti bilong pes;
Nosel i pas o i daunim wok bilong ol fan, na dispela i mekim na kol i no wankain;
No gat strongpela presa kontrol, na dispela i kamapim bikpela presa long stat, we inap kamapim hap defomesen.
Ol tingting bilong helpim:
Testem oltaem ges dew poen blong mekem sua se i drae;
Jekem kondisen blong fan mo nosel bifo yu quen;
Long ol kompleks wokpis, yusim wanpela "stej presurisasen" mod, pre-}kulim long liklik presa pastaim long apim presa long pinisim fez transisen.
4. Noken wet longpela taim tumas pastaim long rausim wokpis long oven.
Taim oven i stop, planti manmeri i no hariap long rausim ol hap, na ol i ting olsem "longpela liklik bai mekim wok." Tasol, ol vekim oven i gat gutpela insulation, na ol hap i kol isi isi insait, inap winim gutpela pre-li tempering temperaja, na dispela i bagarapim ol risal i kam bihain.
Iven moa series, sam martensititik strakja oli stap long low- temperature rein blong longtaem tumas, we i save isi blong mekem ol krek.
Rekomendasen:
Afta we yu kilim i ded, transferem ol pat i go long oven we i mekem yu harem nogud kwiktaem; Noken larim ol i sindaun insait long vekim furnace. 5. Proses Validesen i no inap Skim
Noken ting olsem taim ol paramita i kamap pinis, ol i setim gut. Ol samting bilong ol samting, ol senis long lod bilong oven, na iven ol senis bilong humiditi bilong sisen inap afektim ol laspela risal.
Wanwan batch blong ol niu prodak mo proses i mas gotru long:
Testing bilong hatwok;
Metallurjikal analisis;
Mejamen blong defomesen;
Testing bilong stres i stap yet, sapos i gat nid.
Data i toktok long em yet.
Laswan, wan vekium furnace i givim ol gudfala samting blong wan klin envaeromen, minimal oksidesen, mo minimal defomesen, be bae i no otomatik "stretem" ol mistek.
Iven ol bes ikwipmen oli dipen long ol pipol blong yusum stret.
