Mahimman bayanai da tarihin amfani da ferroboron (FeB)

Ferroboron wani ƙarfe ne na ƙarfe wanda ya ƙunshi boron da baƙin ƙarfe, galibi ana amfani da shi a ƙarfe da simintin ƙarfe.Ƙara 0.07% B zuwa karfe na iya inganta ƙarfin ƙarfin ƙarfe.Boron kara zuwa 18% Cr, 8% Ni bakin karfe bayan jiyya na iya sa hazo hardening, inganta high zafin jiki ƙarfi da taurin.Boron a cikin simintin ƙarfe zai shafi graphitization, don haka ƙara zurfin farin rami don yin tauri kuma ya sa juriya.Ƙara 0.001% ~ 0.005% boron zuwa simintin simintin gyare-gyare yana da amfani ga samar da tawada na spheroidal da inganta rarrabawa.A halin yanzu, ƙananan aluminum da ƙananan ƙarfe na ƙarfe boron sune manyan kayan albarkatun kasa don amorphous gami.Bisa ga ma'auni na GB5082-87, boron na ƙarfe na kasar Sin ya kasu zuwa ƙananan carbon da matsakaicin carbon nau'i biyu na maki 8.Ferroboron wani nau'in nau'i ne na nau'i-nau'i wanda ya hada da baƙin ƙarfe, boron, silicon da aluminum.
Ferric boron shine mai ƙarfi deoxidizer da ƙari na boron a cikin ƙera ƙarfe.Matsayin boron a cikin ƙarfe shine don haɓaka ƙarfin ƙarfi sosai tare da maye gurbin adadi mai yawa na abubuwan haɗin gwiwa tare da ƙaramin adadin boron kawai, kuma yana iya haɓaka kaddarorin injiniyoyi, kaddarorin nakasa sanyi, kayan walda da kaddarorin zafin jiki.
Dangane da abun ciki na carbon baƙin ƙarfe na boron baƙin ƙarfe za a iya raba low carbon grade da matsakaici carbon sa kashi biyu, bi da bi na daban-daban maki na karfe.An jera sinadarai na ferric boron a cikin Table 5-30.Ana samar da ƙananan ƙarfe na ƙarfe na ƙarfe ta hanyar thermit kuma yana da babban abun ciki na aluminum.Matsakaicin carbon boron baƙin ƙarfe ana samar da shi ta hanyar silicothermic, tare da ƙananan abun ciki na aluminum da babban abun ciki na carbon.Masu zuwa za su gabatar da mahimman bayanai da tarihin amfani da boron ƙarfe.
Na farko, mahimman abubuwan amfani da boron baƙin ƙarfe
Lokacin amfani da baƙin ƙarfe boride, ya kamata a lura da wadannan maki:
1. Yawan boron da ke cikin boron ƙarfe ba daidai ba ne, kuma bambancin yana da yawa sosai.Matsakaicin adadin boron da aka bayar a daidaitattun jeri daga 2% zuwa 6%.Domin sarrafa abin da ke cikin boron daidai, ya kamata a narke shi a cikin tanderun induction kafin amfani da shi, sannan a yi amfani da shi bayan bincike;
2. Zaɓi matakin da ya dace na boride baƙin ƙarfe bisa ga ƙarfe mai narkewa.A lokacin da ake narka bakin karfe mai girma-boron don masana'antar makamashin nukiliya, ya kamata a zaɓi ƙarancin carbon, ƙarancin aluminum, ƙarancin ƙarfe boron.A lokacin da ake narkewar baƙin ƙarfe mai ƙunshe da boron, za a iya zaɓar matsakaicin matsakaicin nauyin ƙarfe na ƙarfe;
3. Yawan dawo da boron a cikin baƙin ƙarfe boride ya ragu tare da karuwar abun ciki na boron.Domin samun ingantacciyar ƙimar farfadowa, yana da fa'ida don zaɓar boride baƙin ƙarfe tare da ƙarancin abun ciki na boron.
Na biyu, tarihin baƙin ƙarfe boron
Birtaniya David (H.Davy) a karon farko don samar da boron ta hanyar lantarki.H.Moissan ya samar da babban ƙarfe na ƙarfe na carbon a cikin tanderun wutar lantarki a cikin 1893. A cikin 1920s an sami haƙƙin mallaka da yawa don kera baƙin ƙarfe boride.Haɓaka alluran amorphous da kayan maganadisu na dindindin a cikin 1970s sun haɓaka buƙatun baƙin ƙarfe.A karshen shekarun 1950, cibiyar bincike kan karafa da karafa ta birnin Beijing ta yi nasarar samar da sinadarin iron boide ta hanyar amfani da makamashi.Daga baya, Jilin, Jinzhou, Liaoyang da sauran yawan jama'a, bayan 1966, galibi ta samar da Liaoyang.A shekarar 1973, an samar da boron baƙin ƙarfe ta wutar lantarki a Liaoyang.A cikin 1989, ƙananan ƙarfe na aluminum-boron an haɓaka ta hanyar wutar lantarki.
