Lokacin da ake amfani da bututun ƙarfe na carbon, fim ɗin oxide a saman ba shi da sauƙin faɗuwa.Yawancin lokaci, ana samar da fina-finai na oxide a cikin tanderun dumama.Don haka, yadda za a tsaftace fim din oxide a saman bututun ƙarfe maras nauyi?

1. Iron oxide sikelin tsabtace inji magani

Injin tsaftace sikelin ya ƙunshi babban abin nadi na buroshi na ƙarfe, na'urar tuƙi, tsarin ruwa mai ƙarfi, tsarin ruwa mai sanyaya da na'urar matsawa.Rollers guda biyu tare da wayoyi na karfe (wanda ake kira na'urar buroshi na karfe) an sanya su akan kujerar tebur na abin nadi.The karfe goga rollers suna jujjuya a high gudun a kishiyar shugabanci na slab gudu.

Na'urar tsaftace ma'auni ya dace da ma'aunin ƙarfe da yawa, amma ba zai iya tsaftace ma'auni sosai ba.

2. Ruwa fashe tafkin

Tafkin fashewar ruwan yana amfani da ruwa mai zagayawa a yanayin zafi a matsayin matsakaicin sanyaya, yana sanya billet mai zafin jiki a cikin tafkin, kuma yana amfani da "fashewar ruwa" don cire ma'aunin oxide a saman billet.Ka'idar ita ce lokacin da ruwa ya ci karo da billet mai zafin jiki, ya yi tururi nan take, wanda ya haifar da "fashewar ruwa" da kuma babban adadin tururi mai tsanani.Ƙarfin tasirin tururi yana aiki a saman simintin simintin gyare-gyare don cire ma'auni.A lokaci guda kuma, katako da sikelin oxide a samansa suna da sauri sanyaya a babban zafin jiki, yana haifar da raguwar damuwa.Saboda damuwa daban-daban tsakanin katako da samansa, ma'aunin oxide yana karye kuma ya faɗi.

Ƙirƙirar tana da fa'idodin ƙarancin saka hannun jari, ƙarancin kulawa da ƙarancin samarwa da farashin aiki.Amma ya dace da wasu bakin karfe na austenitic, kamar 301, 304, da dai sauransu.

3. Tsaftace na'urar fashewar harbi

Ana amfani da injunan fashewar harbi sau da yawa don tsaftace ma'aunin oxide akan saman billet.Na'urar fashewar fashewar ta ƙunshi ɗaki mai harbi, kai mai harbi, tsarin isar da iska mai ƙarfi, na'urar tsaftace iska mai ƙarfi, ƙarin na'ura mai fashewa, tsarin cire ƙura, tsarin lubrication da tsarin sarrafa wutar lantarki.Ka'idar aikinsa ita ce a yi amfani da injin ƙarfe mai sauri da injin fashewar fashewar ya jefa don tasiri ma'aunin ƙarfe oxide a saman billet don sa ya faɗi.

Injin fashewar harbi yana da ƙimar aiki mai girma, kuma saurin tsaftacewa zai iya kaiwa 3m/min.Akwai nau'ikan ƙarfe da yawa waɗanda za a iya amfani da su.Tasirin cire ma'aunin ƙarfe oxide yana da kyau.Koyaya, na'urar fashewar fashewar ba zata iya ɗaukar ma'aunin zafin jiki mai zafi ba, kuma ana buƙatar yawan zafin jiki ya zama ƙasa da 80 ° C.Saboda haka, ba za a iya amfani da na'urar fashewar fashewar bam don tsaftace ma'aunin billet ɗin kan layi ba, kuma billet ɗin yana buƙatar sanyaya ƙasa da 80 ° C kafin harbin fashewar.
Ƙarfafa kiyayewabututu maras kyaua amfani iya yadda ya kamata mika rayuwar sabis na m karfe shambura.

A) Tabbatar cewa ma'ajin ko wurin da ake ajiye bututun ƙarfe maras sumul yana da tsafta da tsafta, tare da samun iska mai laushi da magudanar ruwa, kuma ƙasa ba ta da ciyayi da tarkace.
B) Tabbatar cewa ba a haɗa bututun ƙarfe mara nauyi tare da abubuwa masu cutarwa da abubuwa masu cutarwa.Idan an gauraye, halayen lalata na iya faruwa cikin sauƙi.
C) Kada a hada bututun karfe maras sumul da sauran kayan gini don gujewa gurbatar yanayi da wasu abubuwa daban-daban ke haifarwa.
D) Ba za a iya sanya manyan bututun ƙarfe maras sumul ba a cikin ɗakunan ajiya, amma kuma wurin ajiyar dole ne ya cika sharuddan da ke sama, sannan a sanya allunan katako a kasan bututun ƙarfe maras sumul don ware su daga ƙasa.
E) Tabbatar kiyaye wurin da iska mai iska da hana ruwa.
