Mapoinzi akakosha uye nhoroondo yekushandiswa kweferroboron(FeB)

Ferroboron isimbi inoumbwa neboron nesimbi, inonyanya kushandiswa musimbi uye simbi yakakandwa.Kuwedzera 0.07% B kune simbi kunogona kuvandudza zvakanyanya kuoma kwesimbi.Boron yakawedzerwa ku18% Cr, 8% Ni simbi isina tsvina mushure mekurapwa inogona kuita kuti kunaya kwemvura kuome, kunatsiridza kusimba kwekushisa kwakanyanya uye kuoma.Boron musimbi yakakandwa inokanganisa graphitization, nekudaro ichiwedzera kudzika kwegomba jena kuti iite kuoma uye kupfeka kusagadzikana.Kuwedzera 0.001% ~ 0.005% boron kune inogadzika simbi yakakandwa inobatsira kuumba spheroidal inki nekuvandudza kugovera kwayo.Parizvino, yakaderera aruminiyamu uye yakaderera kabhoni iron boron ndiyo huru yezvigadzirwa zveamorphous alloys.Zvinoenderana neGB5082-87 yakajairwa, iron boron yeChina yakakamurwa kuita yakaderera kabhoni uye yepakati kabhoni mapoka maviri emagiredhi masere.Ferroboron is a multicomponent alloy inoumbwa nesimbi, boron, silicon uye aluminium.
Ferric boron ideoxidizer yakasimba uye boron kuwedzera mumiririri mukugadzira simbi.Basa re boron musimbi ndere kuvandudza zvakanyanya kuomarara uye kutsiva huwandu hukuru hwealloying zvinhu zvine huwandu hushoma hweboron, uye inogona zvakare kuvandudza ma mechanic properties, inotonhora deformation zvivakwa, welding zvivakwa uye yakanyanya tembiricha zvinhu.
Zvinoenderana nekabhoni yemukati yeboron iron inogona kukamurwa kuita yakaderera kabhoni giredhi uye yepakati kabhoni giredhi mapoka maviri, zvichiteerana kune akasiyana mamakisi esimbi.Mushonga wekemikari weferric boron wakanyorwa muTable 5-30.Yakaderera kabhoni iron boride inogadzirwa neiyo thermit nzira uye ine yakakwira aluminium yemukati.Medium carbon boron iron inogadzirwa ne silicothermic process, ine yakaderera aluminium yemukati uye yakakwira kabhoni.Izvi zvinotevera zvichasuma pfungwa huru uye nhoroondo yekushandiswa kwesimbi boron.
Kutanga, pfungwa huru dzekushandiswa kwesimbi boron
Paunenge uchishandisa iron boride, zvinotevera zvinofanirwa kucherechedzwa:
1. Kuwanda kwebhoroni musimbi boron haisi yunifomu, uye kusiyana kwakakura zvikuru.Boron mass fraction yakapihwa muyero inotangira pa2% kusvika pa6%.Kuti unyatso kudzora boron yemukati, inofanirwa kudzoserwa muvacuum induction furnace isati yashandiswa, uye yozoshandiswa mushure mekuongorora;
2. Sarudza giredhi rakakodzera resimbi boride maererano nesimbi inonyunguduka.Pakunyungudutsa high-boron Stainless simbi yemagetsi enyukireya, yakaderera kabhoni, yakaderera aluminium, yakaderera phosphorus iron boron inofanirwa kusarudzwa.Pakunyungudutsa boron-ine alloy structural simbi, yepakati kabhoni giredhi simbi boride inogona kusarudzwa;
3. Kudzoreredza kweboron musimbi boride kwakadzikira nekuwedzera kwe boron content.Kuti uwane kupora kuri nani, zvinonyanya kubatsira kusarudza iron boride ine yakaderera boron content.
Chechipiri, nhoroondo yesimbi boron
British David (H.Davy) kekutanga kugadzira boron ne electrolysis.H.Moissan yakagadzira high carbon iron borate mumagetsi arc furnace muna 1893. Mumakore ekuma1920 pakanga pane zvibvumirano zvakawanda zvekugadzira iron boride.Kuvandudzwa kweamorphous alloys uye zvisingaperi magineti zvinhu muma1970s kwakawedzera kudiwa kwesimbi boride.Mukupera kwema1950, China yeBeijing Iron and Steel Research Institute yakabudirira kugadzira iron boride nenzira yekupisa.Zvadaro, Jilin, Jinzhou, Liaoyang uye kumwe kugadzirwa kwakawanda, mushure me1966, kunyanya neLiaoyang kugadzirwa.Muna 1973, iron boron yakagadzirwa nechoto chemagetsi muLiaoyang.Muna 1989, yakaderera aluminium-boron iron yakagadzirwa nemagetsi echoto nzira.
