Nyibilikisa iFayibha yeNtsimbi eNyibilikayo etsalwa ngubushushu

I-Melt-extracted steel fiber
Ifiber yentsimbi
I-fiber yensimbi engenasici

Ingcaciso emfutshane

Izinto ekrwada ziiingots zentsimbi, zisebenzisa izitovu zombane ezinyibilikisa iingcingo zentsimbi engenakutyiwa ukuba zibe ngulwelo lwentsimbi eyi-1500 ~ 1600 ℃, kwaye emva koko ngesantya esiphezulu esijikelezayo esinyibilikayo esikhupha ivili lentsimbi elivelisa iingcingo ezihlangabezana neemfuno ezithile zabathengi bethu. . Xa inyibilika ukuya kumphezulu wentsimbi engamavili, intsimbi elulwelo ivuthuza ngeslot ngamandla aphakathi ngesantya esiphezulu kakhulu nokwenziwa kokupholisa. Amavili anyibilikayo ngamanzi agcina isantya sokupholisa. Le ndlela yokuvelisa ilungele ngakumbi kwaye iphumelele ekuveliseni iifayili zetsimbi zezinto ezahlukeneyo kunye nobukhulu.

Izinto ezikrwada kunye neNkqubo yeMveliso

Usetyenziso

Ukongeza imicu yetsimbi enganyangekiyo enganyangekiyo ubushushu kwizinto ezinqandayo ze-amorphous (i-castables, imathiriyeli yeplastiki, kunye nezixhobo ezidityanisiweyo) ziya kutshintsha ukuhanjiswa koxinzelelo lwangaphakathi lwezinto eziphikisayo, kuthintele ukusasazwa kokuqhekeka, ukuguqula indlela yokuqhekeka kwe-brittle fracture kwi-ductile fracture, kwaye kuphucula kakhulu ukusebenza kwezinto eziphikisayo.

Indawo yesicelo: ukufudumeza umphezulu wesithando somlilo, intloko yesithando somlilo, ucango lwesithando somlilo, isitena somlilo, ukucofa i-groove ezantsi, udonga lomlilo lomlilo we-annular, isigqubuthelo sesithando somlilo, isitywina sesanti, isigqubuthelo se-ladle esiphakathi, indawo engunxantathu wesithando somlilo, i-ladle yentsimbi eshushu, umpu wokutshiza wangaphandle. ukucokisa, isigqubuthelo somsele wesinyithi esishushu, isithintelo se-slag, izinto ezahlukeneyo ezinqandayo ezifakwe kwiziko eliqhumayo, umnyango wesithando somlilo, njl.

Iimbonakalo

Ukuhamba kwenkqubo emfutshane kunye nefuthe elihle le-alloy;
(2) Inkqubo yokucima ngokukhawuleza yenza i-fiber yensimbi ibe nesakhiwo se-microcrystalline kunye namandla aphezulu kunye nokuqina;
(3) Icandelo lomnqamlezo wefayibha limile okwencanyana ngendlela engaqhelekanga, umphezulu urhabaxa ngokwendalo, kwaye unoncamathela olomeleleyo kunye ne-matrix ephikisayo;
(4) Inamandla alungileyo obushushu obuphezulu kunye nokuxhathisa kwi-corrosion yobushushu obuphezulu.
