Inkqubo yeMveliso ye-Alloy ye-TZM

Intshayelelo

Ingxubevange ye-TZM iqhelekile iindlela zokuvelisa yindlela yesinyithi somgubo kunye nendlela yokunyibilikisa i-arc yevacuum. Abavelisi banokukhetha iindlela ezahlukeneyo zokuvelisa ngokweemfuno zemveliso, inkqubo yokuvelisa kunye nezixhobo ezahlukeneyo. Iinkqubo zemveliso ye-alloy ye-TZM zezi zilandelayo: ukuxuba - ukucinezela - pre-sintering - sintering - rolling-annealing -imveliso ye-alloy yeTZM.

Indlela yokunyibilikisa iArc yeVacuum

Indlela yokunyibilikisa i-arc ye-vacuum kukusebenzisa i-arc ukunyibilikisa i-molybdenum ecocekileyo kwaye emva koko ungeze inani elithile le-Ti, i-Zr kunye nezinye izinto ezixutywayo kuyo. Emva kokuxuba kakuhle sifumana i-alloy ye-TZM ngeendlela eziqhelekileyo zokuphosa. Inkqubo yokuvelisa i-vacuum arc smelting ibandakanya ukulungiswa kwe-electrode, iziphumo zokupholisa amanzi, ukuxuba i-arc ezinzileyo kunye namandla okunyibilika njalo njalo. Ezi nkqubo zemveliso zinefuthe elithile kumgangatho we-alloy we-TZM. Ukuze kuveliswe ukusebenza kakuhle, i-alloy ye-TZM kufuneka ifezekise iimfuno ezingqongqo kwinkqubo yemveliso.

Iimfuno ze-Electrode: izithako ze-electrode kufuneka zifane kwaye umphezulu kufuneka wome, uqaqambe, kungabikho oxidation kwaye kungabikho kugoba, iimfuno zokuthotyelwa kokuthe tye.

Isiphumo sokupholisa amanzi: kwi-vacuum consumable smelting furnace, i-crystallizer effect ikakhulu ezimbini: enye kukususa ubushushu obukhutshwe ngexesha lokunyibilika, ukuqinisekisa ukuba i-crystallization ayiyi kutshiswa; enye ichaphazela umbutho wangaphakathi we-TZM i-alloy blanks. I-crystallizer inokudlulisa ukufudumeza okunzulu kwifom engenanto ephantsi kunye nejikelezileyo, isenza iindawo ezingenanto ukuvelisa i-oriented columnar structure. Ingxubevange ye-TZM ngexesha lokunyibilika, ukupholisa ulawulo loxinzelelo lwamanzi kwi-2.0 ~ 3.0 kg / cm², kwaye umaleko wamanzi malunga ne-10mm iyona nto ingcono.

Ukuxuba i-arc ezinzileyo: I-alloy ye-TZM ngexesha lokunyibilika iya kudibanisa nekhoyili engqamene nekristaliza. Emva kombane, iya kuba yintsimi yamagnetic. Isiphumo salo mhlaba wobuzibuthe ikakhulu kukubopha i-arc kunye nokuqinisa idama elinyibilikisiweyo phantsi kokushukuma, ngoko ke isiphumo sokubopha i-arc sibizwa ngokuba “yi-arc ezinzileyo.” Ngaphaya koko, ngokuqina kwemagnethi efanelekileyo kunokunciphisa ukophuka kwekristali.

Amandla okunyibilika: umgubo onyibilikayo uthetha amandla anyibilikayo ngoku kunye nombane, kwaye yinkqubo ebalulekileyo yeeparamitha. Iiparamitha ezingafanelekanga zinokubangela ukusilela ekunyibilikiseni ingxubevange ye-TZM. Khetha amandla afanelekileyo okunyibilika asekelwe ubukhulu becala kumlinganiselo wemoto kunye nekristalizer. I-"L" ibhekisela kumgama phakathi kwe-electrode kunye nodonga lwe-crystallizer, ngoko ixabiso eliphantsi le-L, inkulu indawo yokugubungela i-arc ye-weld pool, ngoko ke kumgubo ofanayo, indawo yokufudumeza i-pool ingcono kwaye isebenza ngakumbi. . Ngokwahlukileyo koko, olu tyando lunzima.

Indlela yeMetallurgy yePowder

Indlela yesinyithi yomgubo kukuxuba kakuhle ubunyulu obuphezulu be-molybdenum powder, i-TiH₂umgubo, ZrH₂umgubo kunye nomgubo wegraphite, emva koko kusetyenzwe ucinezelo olubandayo lwe-isostatic. Emva kokucinezela, i-sintering ekukhuselweni kwegesi ekhuselekileyo kunye nobushushu obuphezulu bufumana izikhewu ze-TZM. Indawo engenanto yokwenza i-hot-rolling (i-hot forging), i-annealing yobushushu obuphezulu, ukuqengqeleka kobushushu obuphakathi (i-intermediate toging forging), i-intermediate yeqondo lobushushu eliphakathi i-annealing kuxinzelelo lwesiqabu, ukuqengqeleka okufudumalayo (ukubumba okushushu) ukufumana i-TZM ialloy (titanium zirconium molybdenum alloy). Inkqubo ye-rolling (forging) kunye nokunyangwa kobushushu obulandelayo kudlala indima ebalulekileyo kwiipropati ze-alloy.

Iinkqubo eziphambili zemveliso zezi zilandelayo: ukuxuba→ ukugawula ibhola → ukucofa okubandayo kwe-isostatic→ngehidrojeni okanye enye igesi ekhuselayo→ukuntywila kumaqondo obushushu aphezulu→iindawo ezingenanto zeTZM→ukuqengqeleka okushushu→ubushushu obuphezuluukuqengqeleka→ukuqengqeleka kobushushu obuphakathi→ubushushu obuphakathi ukunyuswa uxinzelelo→ukuqengqeleka okushushu →i-TZM ingxubevange.
