Inenge zisanzwe nuburyo bwo kuzikumira?
Inenge zikunze kugaragara mu gukora disiki ya feri: umwobo wo mu kirere, kugabanuka kwinshi, umwobo wumucanga, nibindi;Hagati na ubwoko bwa grafite muburyo bwa metallografiya burenze ibisanzwe, cyangwa urugero rwa karbide;Gukomera cyane kwa Brinell biganisha ku gutunganya bigoye cyangwa gukomera kutaringaniye;Imiterere ya grafite ni ntoya, imiterere yubukanishi ntabwo igera ku gipimo gisanzwe, ubukana ni bubi nyuma yo gutunganywa, kandi ububobere bugaragara hejuru ya casting nabwo bubaho rimwe na rimwe.
1. Gushiraho no gukumira ibyobo byo mu kirere: umwobo wo mu kirere ni imwe mu nenge zikunze kugaragara kuri disiki ya feri.Ibice bya feri ni bito kandi binini, gukonjesha no gukomera byihuta, kandi haribishoboka bike ko imvura igwa hamwe nu mwobo wangiza.Ibinure byamavuta ahuza umucanga bifite gaze nini.Niba ibumba ryibumba ryinshi ari ryinshi, ibi bintu byombi akenshi biganisha ku myenge itera muri casting.Byagaragaye ko niba ubuhehere bwumucanga ubumba burenze, igipimo cyibisigazwa byiyongera cyane;Mubice bimwe byoroheje byumucanga, kuniga (kuniga imyenge) hamwe nuduce twinshi (shelling) bikunze kugaragara.Iyo uburyo bwa resin butwikiriwe n'umusenyi ushyushye agasanduku k'uburyo bukoreshwa, imyenge irakomeye cyane kubera kubyara gaze nini;Mubisanzwe, disiki ya feri ifite umusenyi mwinshi ntibikunze kugira inenge yumwuka;
2. Imiterere yumwobo wumwuka: gaze itangwa numusenyi wa disiki ya feri ya feri itera ubushyuhe bwinshi igomba gutembera hanze cyangwa imbere muri horizontalale binyuze mu cyuho cyumucanga mubihe bisanzwe.Disiki yumucanga iba yoroheje, inzira ya gaze iba nto kandi irwanya umuvuduko wiyongera.Igihe kimwe, iyo icyuma gishongeshejwe vuba na bwangu umusenyi wa disiki, gaze nyinshi izaturika;Cyangwa ubushyuhe bwo hejuru bwashongeshejwe nicyuma gifite amazi menshi yumusenyi (kuvanga umucanga utaringaniye) ahantu runaka, bigatera guturika gaze, gucika umuriro no gukora imyenge yunamye;Mu rundi rubanza, gaze yumuvuduko ukabije wibasiye icyuma gishongeshejwe hanyuma ireremba irahunga.Iyo ifumbire idashobora kuyisohora mugihe, gaze izakwirakwira mubice bya gaze hagati yicyuma gishongeshejwe hamwe nubuso bwo hasi bwububiko bwo hejuru, bigatwara igice cyumwanya hejuru ya disiki.Niba icyuma gishongeshejwe kirakomera, cyangwa ibishishwa binini kandi bigatakaza amazi, umwanya ufashwe na gaze ntushobora kuzuzwa, Uzasiga imyenge yo hejuru.Mubisanzwe, niba gaze itangwa ninturusu idashobora kureremba no guhunga ikoresheje icyuma gishongeshejwe mugihe cyagenwe, izaguma hejuru yubuso bwa disiki, rimwe na rimwe igaragara nkicyorezo kimwe, rimwe na rimwe igaragara nyuma yo guturika kugirango ikureho urugero rwa oxyde, kandi rimwe na rimwe biboneka nyuma yo gutunganya, bizatera guta amasaha yo gutunganya.Iyo feri ya feri yibyibushye, bisaba igihe kirekire kugirango icyuma gishongeshejwe kizamuka kinyuze muri disiki hanyuma kijugunye intoki.Mbere yo kurohama, gaze itangwa ninturusu ifite igihe kinini cyo gutembera mu bwisanzure hejuru y’imbere binyuze mu cyuho cy’umucanga, kandi kurwanya gutembera hanze cyangwa imbere mu cyerekezo cya horizontal nabyo ni bito.Kubwibyo, ubuso bwa pore yubuso ntibukunze kubaho, ariko imyenge yitaruye nayo irashobora kubaho.Nukuvuga ko, hari ubunini bukomeye bwo gukora imyenge yunamye cyangwa imyenge yo hejuru hagati yubugari nubunini bwumusenyi.Iyo umubyimba wumucanga umaze kuba munsi yubunini bukomeye, hazabaho impinduka zikomeye za pore.Urwego rukomeye rwiyongera hamwe no kwiyongera kwurwego rwa radiyo ya disiki ya feri hamwe no kunanuka kwa disiki.Ubushyuhe ni ikintu cyingenzi kigira ingaruka mbi.Icyuma gishongeshejwe cyinjira mu cyuho kivuye mu isoko y'imbere, kizenguruka intangiriro yo hagati iyo cyuzuza disiki, kandi gihura n'ikinyuranyo cy'imbere.Bitewe nuburyo burebure buringaniye, ubushyuhe buragabanuka cyane, kandi ubukonje bwiyongera kubwibyo, igihe cyiza cyo kubyimba kureremba no gusohora ni gito, kandi icyuma gishongeshejwe kizakomera mbere yuko gaze isohoka burundu, bityo imyenge iroroshye bibaho.Kubwibyo, igihe cyiza cyo kureremba no gusohora kirashobora kuramba mukongera ubushyuhe bwicyuma gishongeshejwe kuri disiki ihabanye nisoko yimbere.
