I-Ferroboron iyingxube yensimbi eyakhiwe nge-boron ne-iron, esetshenziswa kakhulu ensimbi nasensimbini eyinsimbi.Ukwengeza u-0.07% B ensimbi kungathuthukisa kakhulu ukuqina kwensimbi.I-Boron yengezwe ku-18%Cr, 8%Ni insimbi engagqwali ngemva kokwelashwa ingenza imvula ibe lukhuni, ithuthukise amandla okushisa aphezulu nobulukhuni.I-Boron eku-cast iron izothinta i-graphitization, ngaleyo ndlela ikhulise ukujula kwembobo emhlophe ukuyenza ibe lukhuni futhi imelane nokugqoka.Ukwengeza u-0.001% ~ 0.005% we-boron ensimbini ethambile ethambile kunenzuzo ekwenzeni uyinki oyi-spheroidal kanye nokuthuthukisa ukusatshalaliswa kwayo.Njengamanje, i-aluminium ephansi kanye ne-carbon iron boron ephansi yizinto zokusetshenziswa eziyinhloko zama-alloys amorphous.Ngokwezinga elijwayelekile le-GB5082-87, i-boron yensimbi yaseChina ihlukaniswe ngekhabhoni ephansi nekhabhoni ephakathi izigaba ezimbili zamamaki ayi-8.I-Ferroboron iyingxube ye-multicomponent eyakhiwe ngensimbi, i-boron, i-silicon ne-aluminium.
I-Ferric boron iyi-deoxidizer eqinile kanye ne-agent yokwengeza i-boron ekwenzeni insimbi.Indima ye-boron ensimbi iwukuthuthukisa kakhulu ukuqina kanye nokushintsha inani elikhulu lezakhi ze-alloying ngenani elincane kakhulu le-boron, futhi ingathuthukisa izakhiwo zemishini, izakhiwo ezibandayo, izakhiwo zokushisela kanye nezakhiwo zokushisa okuphezulu.
Ngokusho kokuqukethwe kwekhabhoni ye-boron iron ingahlukaniswa ibe yibanga eliphansi lekhabhoni kanye nebanga eliphakathi kwekhabhoni izigaba ezimbili, ngokulandelana kumamaki ahlukene ensimbi.Ukwakheka kwamakhemikhali e-ferric boron kubhalwe kuThebula 5-30.I-carbon iron boride ephansi ikhiqizwa indlela ye-thermit futhi inokuqukethwe okuphezulu kwe-aluminium.Insimbi ye-carbon boron emaphakathi ikhiqizwa inqubo ye-silicothermic, enokuqukethwe okuphansi kwe-aluminium kanye nokuqukethwe kwekhabhoni ephezulu.Okulandelayo kuzokwethula amaphuzu asemqoka kanye nomlando wokusetshenziswa kwe-iron boron.
Okokuqala, amaphuzu ayinhloko okusetshenziswa kwe-iron boron
Lapho usebenzisa i-iron boride, amaphuzu alandelayo kufanele aqashelwe:
1. Inani le-boron ku-iron boron alifani, futhi umehluko mkhulu kakhulu.Ingxenyana ye-boron mass enikezwe kububanzi obujwayelekile isuka ku-2% iye ku-6%.Ukuze ulawule ngokunembile okuqukethwe kwe-boron, kufanele inyibilikiswe esithandweni sokungeniswa kwe-vacuum ngaphambi kokusetshenziswa, bese isetshenziswa ngemva kokuhlaziya;
2. Khetha izinga elifanele le-iron boride ngokusho kwensimbi encibilikayo.Lapho kuncibilikiswa insimbi engagqwali ene-boron ephezulu yezitshalo zamandla enyukliya, ikhabhoni ephansi, i-aluminium ephansi, i-phosphorus iron boron ephansi kufanele kukhethwe.Lapho kuncibilikiswa insimbi yesakhiwo se-boron equkethe ingxubevange, kungakhethwa i-carbon grade iron boride ephakathi nendawo;
3. Izinga lokutholwa kwe-boron ku-iron boride lehla ngokunyuka kokuqukethwe kwe-boron.Ukuze uthole izinga lokubuyisela elingcono, kunenzuzo kakhulu ukukhetha i-iron boride enokuqukethwe kwe-boron ephansi.
Okwesibili, umlando we-iron boron
UDavid waseBrithani (H.Davy) okokuqala ngqa ukukhiqiza i-boron nge-electrolysis.I-H.Moissan yakhiqiza i-carbon iron borate ephezulu esithandweni somlilo se-arc sikagesi ngo-1893. Ngeminyaka yo-1920 kwakunamalungelo obunikazi amaningi okwenziwa kwe-iron boride.Ukuthuthukiswa kwama-alloys amorphous kanye nezinto zikazibuthe unomphela ngawo-1970 kwandisa isidingo se-iron boride.Ngasekupheleni kwawo-1950, i-Beijing Iron and Steel Research Institute yaseChina yathuthukisa ngempumelelo i-iron boride ngendlela ye-thermit.Kamuva, uJilin, Jinzhou, Liaoyang nokunye ukukhiqizwa kwenqwaba, ngemuva kuka-1966, ikakhulukazi ukukhiqizwa kweLiaoyang.Ngo-1973, i-iron boron yakhiqizwa isithando somlilo sikagesi e-Liaoyang.Ngo-1989, i-aluminium-boron iron ephansi yathuthukiswa ngendlela yesithando somlilo sikagesi.
