Cold jawo ingancin ingancin bututu da rigakafin

Hannun sarrafa bututu mara ƙarfi mara ƙarfi:

① sanyi mirgina ② zane mai sanyi ③ juyi

a. Ana amfani da jujjuyawar sanyi da zane mai sanyi don: daidaito, bangon bakin ciki, ƙaramin diamita, ɓangaren giciye mara kyau da bututu masu ƙarfi.

b. An fi amfani da kadi don: samar da babban diamita, katangar bakin ciki ko babban diamita, bututun ƙarfe na bangon bakin ciki, kuma yana da yanayin maye gurbinsu da bututun walda (tushen ƙarfe, walda, maganin zafi, da sauransu).

Babban tsarin gudana na samar da bututun ƙarfe mara nauyi ta zane mai sanyi:

Shirye-shiryen bututu mara kyau → Zane mai sanyi na bututun ƙarfe → Kammalawa da sarrafa bututun ƙarfe da aka gama → Dubawa

Halayen bututun ƙarfe maras sumul da aka samar ta hanyar zane mai sanyi (idan aka kwatanta da mirgina mai zafi)

① Diamita na waje na bututun karfe ya zama karami har sai ana iya samar da bututun capillary

② bangon bututun ƙarfe ya fi siriri

③ Karfe bututu yana da mafi girma girma daidaito da kuma mafi ingancin surface

④ The giciye-section siffar karfe bututu ne mafi hadaddun, da m giciye-sashe da na musamman-dimbin yawa karfe bututu za a iya samar.

⑤ Aikin bututun ƙarfe ya fi kyau

⑥ Babban farashin samarwa, babban kayan aiki da amfani da ƙira, ƙarancin yawan amfanin ƙasa, ƙaramin fitarwa, da buƙatun kare muhalli mafi girma

Cold jawo bututu ingancin lahani da rigakafin su

⒈ The ingancin lahani na sanyi-zana karfe bututu, yafi hada da: m bango kauri na karfe bututu, out-of-haƙuri waje diamita, surface fasa, surface mike Lines da scratches, da dai sauransu.

①Kaurin bango mara daidaituwa na bututun ƙarfe da aka zana sanyi yana da alaƙa da kauri na bangon daidaitaccen bututu, hanyar zane, layin tsakiya na zane, siffar rami, sigogin tsari na lalata da yanayin lubrication.

a. Haɓaka daidaiton kauri na bango na bututun bututu shine muhimmin abin da ake buƙata don haɓaka daidaiton kaurin bango na bututun ƙarfe da aka zana sanyi.

b. Babban manufar extubation ba tare da mandrel shine don rage diamita da nakasawa

c. Siffar rami muhimmin abu ne da ke shafar kaurin bango mara daidaituwa na bututun ƙarfe da aka zana sanyi.

d. Hakanan hanya ce mai inganci don tabbatar da ingancin bututun mara kyau, cire ma'aunin baƙin ƙarfe oxide akan saman sa, da haɓaka ingancin lubrication.

②A yayin aikin samarwa, ya kamata a ba da hankali sosai ga lalacewa da tsagewar dacewa da tsarawa

③Domin rage tsagewar saman bututun karfe bayan an ja, sai a zabi guraben bututun da suka cancanta, sannan a kasa kasa. A lokacin da pickling da bututu blanks, shi wajibi ne don hana kan-picking don kauce wa pitting ko hydrogen embrittlement, da kuma don hana karkashin-pickling da bai cika tsaftacewa na oxide sikelin, tabbatar da annealing ingancin bututu blank lokacin amfani, rungumi dabi'ar m tube zane Hanyar, zaži dace nakasawa tsari sigogi da kayan aiki siffar, da kuma karfafa daidaitawa da kuma duba na zane cibiyar line.

④ Inganta ingancin pickling da lubrication na bututu mara kyau, tabbatar da taurin kayan aiki, daidaituwa da gamawa zai taimaka rage abin da ya faru na madaidaiciyar layi da tarkace akan bututun ƙarfe.
