Manufacturing nzira
1. Iyo yakawanda boiler tube tembiricha iri pazasi 450 ℃, pombi yemumba inonyanya kugadzirwa neNo. 10, kwete.20 carbon bonded simbi inopisa yakakungurutswa pombi kana inotonhora inodhonzwa pombi.
2. High-pressure boiler tubes inowanzoshandiswa pasi pekushisa kwepamusoro uye mamiriro ekudzvinyirira.Pasi pechiito chepamusoro tembiricha flue gasi uye mhute yemvura, oxidation uye corrosion zvichaitika.Iyo pombi yesimbi inodiwa kuti ive yakasimba yakasimba yakasimba, yakakwira oxidation corrosion resistance uye yakanaka microstructure kugadzikana.
3. High pressure boiler chubhu imhando yeboiler chubhu, ndeyechikamu chesimbi isina musono.Iyo nzira yekugadzira yakafanana neye seamless chubhu yakakwira pressure boiler chubhu, asi pane zvakaomesesa zvinodiwa pagiredhi resimbi rinoshandiswa kugadzira simbi chubhu.High-pressure boiler tubes inowanzoshandiswa pasi pekushisa kwepamusoro uye mamiriro ekumanikidza.High pressure boiler chubhu inonyanya kushandiswa kugadzira superheater chubhu, reheater chubhu, pombi pombi, hombe pombi yehutsi uye zvichingodaro zvekumanikidza kwakanyanya uye Ultra high pressure boiler.
4. Nokuti boiler tube inoshanda pasi pekushisa kwepamusoro uye kudzvinyirira kwakanyanya kwenguva yakareba, zvinhu zvinokambaira, plastiki uye kuoma kunoderera, sangano rekutanga rinoshanduka, kuora uye zvichingodaro.Machubhu esimbi anoshandiswa semaboilers anofanira kunge aine:
(1) Simba rinogara rakakwana;
(2) Yakakwana yepurasitiki deformation kugona;
(3) Kusanyanya kuchembera uye brittleness yekupisa;
(4) Yakakwira oxidation kuramba, marasha emarasha kuramba, yakanyanya tembiricha kuramba kune yakasikwa gasi corrosion, chiutsi uye kusagadzikana ngura kuita;
(5) Kugadzikana kwakanaka kwesangano uye kuita kwakanaka kwemaitiro.
Simbi yeyakanyanya kudzvanywa boiler chubhu ndeye kabhoni simbi uye pearlite, ferritic uye austenitic simbi isina kupisa inodzivirira kupisa.Kuti uvandudze kushanda kwemafuta emagetsi ekugadzira magetsi uye kuderedza kushandiswa kwemafuta, kusimudzira hukuru hukuru, yakakwirira parameter (yakakwirira tembiricha, yakanyanya kudzvanywa) magetsi emagetsi ekupisa (anopfuura 1000MW) anopihwa pamberi penyika.Steam pressure yakawedzera kusvika 31.5 ~ 34.3MPa, superheated steam tembiricha inosvika 595 ~ 650 ℃, kusvika pakuvandudzwa kwe-ultra-high pressure yakakosha pressure, saka high pressure boiler chubhu inoisa mberi zvinodiwa.Igiredhi nyowani resimbi rakagadzirwa kuti rizadzise kudiwa kweakakwira parameter simba rekudyara boiler.
Yakakwira yekumanikidza boiler chubhu yekugadzira nzira yekugadzira，Shandisa classification
Kune yakaderera uye yepakati kudzvanywa bhaira (kushanda kumanikidza kazhinji hakusi kupfuura 5.88mpa, tembiricha yekushanda iri pazasi 450 ℃) yekupisa pamusoro pepombi;Inoshandiswa kune yakakwira dhizaini boiler (yekushanda kumanikidza kazhinji pamusoro pe9.8mpa, tembiricha yekushanda iri pakati pe450 ℃ ~ 650 ℃) kupisa pamusoro pepombi, economizer, superheater, reheater, petrochemical indasitiri pombi, nezvimwe.
Zvinoenderana nekuumbwa kwechikamu chemidziyo inogona kukamurwa kuita 20G yakakwira-kumanikidza boiler chubhu, 12Cr1MoVG yakakwira-kudzvanya boiler chubhu, simbi yekutsvagisa 102 high-pressure boiler chubhu, 15CrMoG high-pressure boiler chubhu, 5310 high-pressure boiler chubhu, 3087 yakaderera uye yepakati kudzvanywa boiler chubhu, 40Cr yakakwira-kudzvanywa boiler chubhu, 1Cr5Mo yakakwira-kudzvanywa boiler chubhu, 42CrMo yakakwirira-kumanikidza boiler chubhu.
Yakakwira yekumanikidza boiler chubhu yekugadzira nzira yekugadzira, Mamiriro uye kutaridzika kwemhando
(1) GB3087-2008 "Seamless Simbi pombi yeYakadzika uye yepakati kudzvanywa boiler" zvigadziro.Zvinotsanangurwa zvesimbi machubhu eakasiyana dhizaini boilers, madhayamita 10 ~ 426mm, 43 marudzi ese.Kune makumi maviri nemapfumbamwe emhando dzemadziro ukobvu kubva pa1.5 mm kusvika 26mm.Nekudaro, iyo dhayamita yekunze uye kukora kwemadziro epombi inopisa inopisa, pombi hombe yeutsi, pombi diki yeutsi uye arch zvidhinha pombi inoshandiswa mulocomotive boiler inotsanangurwa neimwe nzira.
(2) GB5310-2008 "Seamless Steel Tube for High pressure Boiler" inopisa yakakungurutswa pombi dhayamita 22 ~ 530mm, rusvingo ukobvu 20 ~ 70mm.Inotonhora inodhonzwa (inotonhora yakakungurutswa) chubhu dhayamita 10 ~ 108mm, madziro ukobvu 2.0 ~ 13.0mm.
(3) GB3087-82 "Seamless simbi chubhu yepasi uye yepakati kumanikidza bhaira" uye GB5310-95 "seamless simbi chubhu yeyakanyanya kumanikidza bhaira" zvigadziro.Kuonekwa kwehutano: kuputika, kupeta, kupeta, kuputika, kupatsanurwa uye makwinya hazvibvumirwi mukati uye kunze kwepamusoro pepombi yesimbi.Izvi zvinokanganisa zvinofanira kubviswa zvachose.Kudzika kwemvumo hakufaniri kudarika kutsauswa kwakashata kwemazita emadziro ukobvu, uye ukobvu chaihwo hwemadziro pakucheneswa hahuzove hushoma pane hudiki hunobvumidzwa ukobvu hwemadziro.
