1: Kupisa KweHastelloy B-2 alloys, zvakakosha zvikuru kuchengetedza nzvimbo yakachena uye isina tsvina isati yasvika uye panguva yekupisa. Hastelloy B-2 inoita brittle kana ichipisa munzvimbo ine sarufa, phosphorus, lead, kana zvimwe zvinosvibisa simbi inonyungudika, kunyanya kubva kumaki, tembiricha inoratidza pendi, girizi uye zvinwiwa, utsi. Iyo flue gasi inofanira kunge ine yakaderera sarufa; semuenzaniso, sulfur yemukati yegasi yegasi uye liquefied petroleum gasi haipfuure 0.1%, iyo sarufa yemhepo yemuguta haipfuure 0.25g/m3, uye sarufa yemafuta emafuta haipfuure 0.5%. Iyo gasi nharaunda inodiwa pachoto chekudziya inzvimbo isina kwayakarerekera kana mwenje inoderedza nharaunda, uye haigone kuchinjika pakati peoxidizing uye kudzikisira. Murazvo uri muchoto haugone kukanganisa zvakananga Hastelloy B-2 alloy. Panguva imwecheteyo, zvinhu zvinofanirwa kupiswa kune tembiricha inodiwa pakukurumidza kupisa kwekupisa, ndiko kuti, tembiricha yechoto chekupisa inofanira kusimudzwa kune tembiricha inodiwa kutanga, uyezve zvinhu zvacho zvinofanirwa kuiswa muchoto chekupisa. .
2: Kupisa kushanda Hastelloy B-2 alloy inogona kupisa yakashanda mukati me900 ~ 1160 ℃, uye inofanira kudzimwa nemvura mushure mekugadzirisa. Kuti ive nechokwadi chekudzivirira kwakanakisa ngura, inofanirwa kuvharwa mushure mekushanda kupisa.
3: Kutonhora kushanda Hastelloy B-2 alloy inofanira kupinda mhinduro kurapwa. Sezvo iine yakanyanya kuoma basa rekuita kupfuura austenitic Stainless simbi, iyo yekuumba midziyo inofanira kunyatsotariswa. Kana kutonhora kuumba maitiro kunoitwa, interstage annealing inodiwa. Kana iyo inotonhora yekushanda deformation inodarika 15%, kurapwa kwemhinduro kunodiwa usati washandiswa.
4: Kupisa kupisa Kugadzirisa kupisa kwekushisa kwekushisa kunofanira kudzorwa pakati pe 1060 ~ 1080 ° C, uye ipapo mvura-yakanyoroveswa uye yakadzimwa kana kana hupamhi hwezvinhu huri pamusoro pe 1.5mm, inogona kukurumidza kunyungudutswa nemhepo kuti iwane yakanakisisa yekudzivirira. Panguva ipi neipi yekushanda kwekupisa, zvidziviriro zvinofanira kutorwa kuchenesa pamusoro pezvinhu. Kupisa kupisa kwezvinhu zveHastelloy kana midziyo yemidziyo inofanirwa kutarisisa kune zvinotevera nyaya: Kuti udzivise kupisa kurapwa deformation yezvikamu zvemidziyo, mhete dzekusimbisa simbi dzinofanira kushandiswa; iyo tembiricha yevira, kupisa uye kutonhora nguva inofanira kunyatsodzorwa; Ita pretreatment kudzivirira kupisa kutsemuka; mushure mekupisa kupisa, 100% PT inoshandiswa kune zvikamu zvinopisa; kana kupisa kwemafuta kukaitika panguva yekupisa kupisa, avo vanoda kugadzirisa welding mushure mekugaya uye kubvisa vanofanira kutora yakakosha kugadzirisa welding process.
5: Descaling Maokisi ari pamusoro peHastelloy B-2 alloy uye mavara ari padyo nemusono we welding anofanira kukwenenzverwa negumbo rekukuya. Sezvo Hastelloy B-2 alloy inonzwa kune oxidizing yepakati, yakawanda nitrogen-ine gasi inozogadzirwa panguva yekunhonga.
6: Machining Hastelloy B-2 alloy inofanira kugadzirwa mune annealed state, uye inofanira kuva nekunzwisisa kwakajeka kwebasa rayo kuoma. Iyo yakaomeswa dhizaini inofanirwa kutora yakakura chiyero chekudya uye chengetedza chishandiso chiri mukuenderera kushanda mamiriro.
7: Welding Hastelloy B-2 alloy weld metal uye nzvimbo inopisa-inopisa zviri nyore kudonha β chikamu uye kutungamirira kune varombo Mo, iyo inowanzoita intergranular corrosion. Naizvozvo, iyo welding process yeHastelloy B-2 alloy inofanira kunyatsogadzirwa uye kunyatsodzorwa. The general welding process ndeiyi: the welding material is ERNi-Mo7; iyo welding nzira ndeyeGTAW; kutonhora pakati pezvikamu zvekutonga hakusi kupfuura 120 ° C; iyo dhayamita yewaya yewelding ndeye φ2.4 uye φ3.2; iyo welding ikozvino i90 ~ 150A. Panguva imwecheteyo, kusati kwave nekuputika, tambo yekutsvaira, groove yechikamu chakasungirirwa uye zvikamu zviri pedyo zvinofanira kunge zvakasvibiswa uye zvakasvibiswa. Iyo yekupisa conductivity yeHastelloy B-2 alloy idiki zvakanyanya pane iyo yesimbi. Kana imwe groove yakaita V-shaped groove yakashandiswa, groove angle inofanira kunge yakakomberedza 70 °, uye kupisa kwakadzika kunofanira kushandiswa. Post-weld kupisa kurapwa kunogona kubvisa kusara kunetseka uye kunatsiridza kushushikana ngura kupwanya kuramba.
