1: Gushyushya Amavuta ya Hastelloy B-2, ni ngombwa cyane kugira isuku hejuru kandi itarangwamo umwanda mbere no mugihe cyo gushyushya. Hastelloy B-2 iracika intege iyo ishyutswe mubidukikije birimo sulfure, fosifore, gurş, cyangwa ibindi byuma bidashonga cyane, cyane cyane kubimenyetso, ubushyuhe bwerekana irangi, amavuta n'amazi, umwotsi. Gazi ya flue igomba kuba irimo sulfure nkeya; nk'urugero, sulferi ya gaze gasanzwe na gaze ya peteroli yamazi ntirenza 0.1%, sulfure yumuyaga wo mumijyi ntirenza 0.25g / m3, naho sulferi irimo amavuta ya peteroli ntirenza 0.5%. Ibidukikije bya gaze bisabwa ku itanura rishyushya ni ibidukikije bidafite aho bibogamiye cyangwa ibidukikije bigabanya urumuri, kandi ntibishobora guhinduka hagati ya okiside no kugabanya. Umuriro mu itanura ntushobora kugira ingaruka ku buryo butaziguye Hastelloy B-2. Muri icyo gihe, ibikoresho bigomba gushyukwa ku bushyuhe bukenewe ku muvuduko wihuse, ni ukuvuga ko ubushyuhe bw’itanura bugomba kubanza kuzamurwa kugeza ku bushyuhe bukenewe, hanyuma ibikoresho bigomba gushyirwa mu itanura kugira ngo bishyuhe .
2: Gukora bishyushye Hastelloy B-2 ibinyobwa birashobora gushyuha bikozwe murwego rwa 900 ~ 1160 and, kandi bigomba kuzimwa namazi nyuma yo gutunganywa. Kugirango hamenyekane neza kurwanya ruswa, igomba gufatanwa nyuma yo gukora bishyushye.
3: Ubukonje bukora Hastelloy B-2 ibinyobwa bigomba kuvurwa. Kubera ko ifite igipimo cyinshi cyo gukomera kurenza icyuma cya austenitis, ibyuma bigomba kubitekerezaho neza. Niba inzira ikonje ikozwe, interstage annealing irakenewe. Iyo imikorere ikonje ikonje irenze 15%, harasabwa kuvura igisubizo mbere yo gukoreshwa.
4. Mugihe cyose cyo gushyushya, hagomba gufatwa ingamba zo gusukura hejuru yibikoresho. Gutunganya ubushyuhe bwibikoresho cyangwa ibikoresho bya Hastelloy bigomba kwitondera ibibazo bikurikira: Kugirango hirindwe uburyo bwo gutunganya ubushyuhe bwibice byibikoresho, hagomba gukoreshwa impeta zishimangira ibyuma; ubushyuhe bw'itanura, gushyushya no gukonjesha bigomba kugenzurwa cyane; Kora kwitegura kugirango wirinde gucika; nyuma yo kuvura ubushyuhe, 100% PT ikoreshwa mubice bivura ubushyuhe; niba ubushyuhe bwumuriro bubaye mugihe cyo kuvura ubushyuhe, abakeneye gusana gusudira nyuma yo gusya no kurandura bagomba gufata inzira idasanzwe yo gusudira.
5. Kubera ko amavuta ya Hastelloy B-2 yunvikana muburyo bwa okiside, gaze irimo azote nyinshi izakorwa mugihe cyo gutoragura.
6: Gukora imashini ya Hastelloy B-2 igomba gutunganyirizwa hamwe, kandi igomba kuba isobanukiwe neza nakazi kayo. Igice cyakomye kigomba gufata igipimo kinini cyo kugaburira kandi kigakomeza igikoresho muburyo bukomeza.
7: Welding Hastelloy B-2 alloy weld ibyuma na zone yibasiwe nubushyuhe biroroshye kugwa β icyiciro kandi biganisha kuri Mo ikennye, ikunda kwangirika hagati yimiterere. Kubwibyo, gahunda yo gusudira ya Hastelloy B-2 ivanze igomba gutegurwa neza kandi ikagenzurwa cyane. Igikorwa rusange cyo gusudira nuburyo bukurikira: ibikoresho byo gusudira ni ERNi-Mo7; uburyo bwo gusudira ni GTAW; ubushyuhe buri hagati yubugenzuzi ntiburenze 120 ° C; umurambararo w'insinga zo gusudira ni .42.4 na φ3.2; umuyoboro wo gusudira ni 90 ~ 150A. Muri icyo gihe, mbere yo gusudira, insinga yo gusudira, umwobo wigice cyasuditswe hamwe nibice byegeranye bigomba kwanduzwa no kwangirika. Amashanyarazi yumuriro wa Hastelloy B-2 avanze ni nto cyane ugereranije nicyuma. Niba igikoni kimwe kimeze nka V gikoreshwa, inguni igomba kuba hafi 70 °, kandi hagomba gukoreshwa ubushyuhe bwo hasi. Kuvura ubushyuhe nyuma yo gusudira birashobora gukuraho imihangayiko isigaye no kunoza imitekerereze ya ruswa.
