① Boemo ba delibari
Boemo ba thomello bo bolela boemo ba deformation ea ho qetela ea polasetiki kapa kalafo ea ho qetela ea mocheso oa sehlahisoa se fanoeng. Ka kakaretso, lihlahisoa tse fanoang ntle le phekolo ea mocheso li bitsoa boemo bo chesang kapa bo batang (ho phuthoa); lihlahisoa tse fanoang ka phekolo ea mocheso li bitsoa boemo ba phekolo ea mocheso, kapa li ka bitsoa normalizing, quenching le tempering, tharollo, annealing states. Boemo ba thomello bo lokela ho bontšoa konteraka ha o laela.
②Ho fana ka boima ba 'mele kapa boima ba 'mele
Boima ba sebele - sehlahisoa se fanoa ho ea ka boima bo lekantsoeng (ka sekala);
Boima ba khopolo - ha o fana, boima ba sehlahisoa bo baloa ho ea ka boholo ba lebitso la thepa ea tšepe. Foromo ea lipalo ke e latelang (haeba lihlahisoa li fanoa ho latela boima ba 'mele, li lokela ho bontšoa konteraka)
Foromo ea lipalo bakeng sa boima ba theoretical (tekanyo ea tšepe ke 7.85 kg/dm3) ka mithara ea tube ea tšepe:
W=0.02466(DS)S
Ka foromo:
W——tekanyo ea boima ba mithara ea tube ea tšepe, kg/m;
D--karolo e ka ntle ea bophara ba tube ea tšepe, limilimithara;
S - - botenya ba lebitso la lebota la tube ea tšepe, mm.
③Maemo a tiisetso
Tlas'a lipehelo tsa maemo a hajoale, ho lekola lihlahisoa le ho netefatsa ho latela lipehelo tsa maemo ho tsejoa e le maemo a tiisetso. Maemo a tiisetso a ka aroloa ka:
A、 Maemo a tiisetso a mantlha (a tsejoang hape e le maemo a hlokahalang). Ho sa tsotelehe hore na li boletsoe ho konteraka ke moreki, u lokela ho hlahloba ntho ena ho latela lipehelo tse tloaelehileng, 'me u netefatse hore liphetho tsa liteko li kopana le lipehelo ka maemo. Mohlala, libopeho tsa lik'hemik'hale, thepa ea mochini, ho kheloha ha maemo, boleng ba bokaholimo, ho lemoha tšenyo, tlhahlobo ea khatello ea metsi kapa liteko tsa theknoloji tse kang ho hatella bataletseng le ho atolosoa ha tube kaofela ke maemo a hlokahalang.
B, Tumellano e tiisa maemo: ho phaella ho maemo a motheo a tiisetso, ho ntse ho e-na le "ho ea ka litlhoko tsa moreki, maemo a lokela ho buisanoa le mahlakore ka bobeli, 'me maemo a lokela ho bontšoa ka konteraka" kapa "haeba moreki a hloka ..., e lokela ho bontšoa konteraka”; bareki ba bang ba na le litlhoko tse thata ho latela maemo a tloaelehileng a tiisetso (joalo ka lipina, thepa ea mochini, ho kheloha ha litekanyo, joalo-joalo) kapa ba eketsa lisebelisoa tsa tlhahlobo (tse kang ellipticity, botenya bo sa lekaneng ba lebota, joalo-joalo). Ka holim'a lipehelo le litlhoko li lokela ho buisanoa ke mahlakore ka bobeli a mofani oa thepa le moreki, Tumellano ea Theknoloji ea Availability e lokela ho saenoa, 'me litlhoko li tlameha ho bontšoa konteraka. Ka hona, maemo ana a boetse a bitsoa maemo a tiiso ea tumellano. Ka kakaretso, litheko tsa lihlahisoa tse nang le maemo a tiisetso ea tumellano li lokela ho eketseha.
④"Batch" ho "batch standard" e bolela karolo ea tlhahlobo, ke hore. sehlopha sa tlhahlobo. Sehlopha se arotsoeng ka yuniti ea phano e bitsoa "delivery batch". Haeba palo ea palo ea ho fana e le khōlō, sehlopha sa ho fana se ka kenyelletsa lihlopha tse 'maloa tsa tlhahlobo; haeba palo ea beche ea thomello e le nyane, sehlopha sa tlhahlobo se ka kenyelletsa lihlahisoa tse 'maloa tsa thomello. Liqapi tsa "batch" hangata li laoloa ka tsela e latelang (sheba maemo a amanang):
A、Mong le e mong beche e lokela ho bopilwe ka li-tubes tšepe ea mohlala e tšoanang (tšepe kereite), e tšoanang boiler (tanka) nomoro kapa tšoanang' mè boiler palo heaters, litlhaloso tse tšoanang le oona tsamaisong mocheso mocheso (nomoro boiler).
B, Ha e le boleng k'habone tšepe phala le mokelikeli tube, sehlopha ka 'na a qapa ea mohlala e tšoanang, tlhaloso e tšoanang le oona tsamaisong mocheso mocheso (nomoro boiler) ea boilers fapaneng (litanka).
C, E 'ngoe le e' ngoe ea li-tubes tse entsoeng ka tšepe tse cheselitsoeng li lokela ho etsoa ka mokhoa o tšoanang (lihlopha tsa tšepe) le litlhaloso tse tšoanang.
⑤Tšepe ea boleng bo holimo le tšepe ea boleng bo holimo
Ka litekanyetso tsa GB / T699-1999 le GB / T3077-1999, tšepe eo mohlala oa eona o tsamaeang le "A" ke tšepe ea boleng bo phahameng, ho fapana le hoo, tšepe ke tšepe ea boleng bo akaretsang. Ts'epe ea boleng bo holimo e etelletsoe pele ke tšepe ea boleng maemong a latelang kapa ka botlalo:
A, Fokotsa mefuta e fapaneng ea dikahare tsa tlhamo;
B, Fokotsa litaba tsa lintho tse kotsi (tse kang sebabole, phosphorus le koporo);
C, Netefatsa bohloeki bo phahameng (litaba tsa li-inclusions tse seng tsa tšepe li lokela ho ba tse nyane);
D, Netefatsa thepa e phahameng ea mochini le thepa ea mahlale.
⑥Tsamaiso ea longitudinal le tataiso e tšekaletseng
Ka mokhoa o tloaelehileng, tataiso ea longitudinal e tsamaisana le tataiso ea ts'ebetso (ke hore, hammoho le tataiso ea ts'ebetso); karohano e tšekaletseng e otlolohile ka tataiso ea ts'ebetso (tataiso ea ts'ebetso ke tataiso ea axial ea tube ea tšepe).
Nakong ea tlhahlobo ea phello, ho robeha ha mohlala oa longitudinal ho lokela ho ba holimo le tataiso ea ts'ebetso, kahoo e bitsoa fracture e fapaneng; ho robeha ha mohlala o pota-potileng ho lokela ho tsamaisana le tataiso ea ho sebetsa, kahoo e bitsoa ho robeha ha longitudinal.
