Uburyo bwo kwinjizamo ifuru
Ikoreshwa rya kaburiseri rikwiriye gushongeshwa mu itanura rikoreshwa mu gushongesha, ariko ikoreshwa ryihariye ntabwo ringana bitewe n'ibisabwa mu buryo.
(1) Mu itanura rishongeshwa hakoreshejwe icyuma gishongesha, hakurikijwe igipimo cyangwa ibisabwa bingana na karuboni hamwe n’ibikoresho byongewe mu gice cyo hasi cy’itanura, igipimo cyo kugarura gishobora kugera ku kigero kirenga 95%;
(2) icyuma gishonga mu mazi iyo ingano ya karuboni idahagije kugira ngo ihindure igihe cya karuboni, banza ukoreshe icyuma gishyushya mu itanura, hanyuma wongeremo icyuma gishyushya mu mazi, binyuze mu gushyushya mu mazi, gukurura mu mazi cyangwa gukurura mu buryo bw'ubukorano kugira ngo bishongeshe karuboni, igipimo cyo kugarura gishobora kuba hafi 90, niba uburyo bwo gushonga mu mazi mu bushyuhe buke, ni ukuvuga ko amashanyarazi ashongesha igice cy'ubushyuhe bw'icyuma gishongeshejwe ari buke, icyuma cyose gishongesha mu mazi iyo cyongewe mu mazi, Muri icyo gihe, gishyirwa mu mazi gifite amashanyarazi akomeye kugira ngo kidasohoka ku buso bw'icyuma gishongeshejwe. Ubu buryo bushobora kongera amashanyarazi mu mazi ku kigero kirenze 1.0%.
Gukoresha neza icyuma gitera kaburimbo mu itanura ry’inyongera
1, ikoreshwa ry'itanura ry'amashanyarazi rya 5T cyangwa rirenzeho, ibikoresho fatizo ni bimwe kandi bihamye, turasaba uburyo bwo kongeramo ibintu bitatanye. Dukurikije ibisabwa ku gipimo cya karuboni, dukurikije igipimo cy'ibikubiye mu bikoresho, igikoresho gitera kaburimbo n'icyuma gitera kaburimbo hamwe na buri gice cy'ibikoresho kugira ngo bihuze itanura mu gice cyo hasi, urwego rw'icyuma gitera kaburimbo urwego rw'igikoresho gitera kaburimbo, igipimo cyo kwinjiza karuboni gishobora kugera kuri 90%-95%, igikoresho gitera kaburimbo mu gushonga ntigitera kaburimbo, bitabaye ibyo byoroshye kuzingira mu myanda, bigira ingaruka ku kwinjiza karuboni;
2. Hakoreshwa itanura ripima frequency ikoreshwa rya 3T, kandi ibikoresho fatizo ni bimwe kandi bihamye. Turasaba uburyo bwo kongeramo ibintu hagati. Iyo icyuma gishongeshejwe gishongeshejwe cyangwa gisigaye mu itanura, icyuma gishongeshejwe gishyirwa ku buso bw'icyuma gishongeshejwe icyarimwe, hanyuma icyuma gishongeshejwe ako kanya. Ikigo gishongeshejwe gishyirwa mu cyuma gishongeshejwe, ku buryo icyuma gishongeshejwe gihura neza n'icyuma gishongeshejwe, kandi igipimo cyo kwinjiza kikaba kirenze 90%;
3, gukoresha itanura rito rikoresha amashanyarazi riciriritse, ibikoresho fatizo birimo icyuma cy'ingurube n'ibindi bintu birimo karuboni nyinshi, turasaba ko byatunganywa neza. Nyuma yo gushonga kw'icyuma/icyuma gishongeshejwe, hindura ingano ya karuboni, ishobora kongerwa ku buso bw'icyuma/icyuma gishongeshejwe, binyuze mu gukurura amazi y'icyuma (icyuma) cyangwa gukurura by'ubukorano kugira ngo bishonge kandi bikinjize, igipimo cyo kwinjiza karuboni ni hafi 93%.
Uburyo bwo gushyira mu gifuru kaburimbo hanze
1. Shyira ifu ya grafiti mu gafuka
Ifu ya grafiti nk'ikintu gikoresha kaburimbo, gitera ingano ya 40kg/t, byitezwe ko ingano ya karuboni mu cyuma gitemba iva kuri 2% ikagera kuri 3%. Uko ingano ya karuboni mu cyuma gitemba igenda yiyongera buhoro buhoro, niko igipimo cyo gukoresha karuboni cyagabanutse. Ubushyuhe bw'icyuma gitemba mbere yo gukoresha kaburimbo bwari 1600℃, naho ubushyuhe busanzwe nyuma yo gukoresha kaburimbo bwari 1299℃. Kaburimbo ya grafiti, muri rusange ikoresha azote nk'umutwaro, ariko mu mikorere y'inganda, umwuka ufunze woroshye, kandi ogisijeni iri mu mwuka ufunze igatanga CO2, ubushyuhe bwa shimi bushobora kwishyura igice cy'igabanuka ry'ubushyuhe, kandi ikirere cyo kugabanya CO2 kirafasha kunoza ingaruka za kaburimbo.
2, ikoreshwa ry'icyuma gitera kaburimbo
Ifu ya grafiti 100-300 ishobora gushyirwa mu ipaki, cyangwa mu mwobo w'icyuma usohokamo amazi, nyuma y'uko icyuma kivuye mu mazi gikanguwe neza, uko bishoboka kose kugira ngo karuboni ishonge, igipimo cyo kugarura karuboni ni hafi 50%.
Mu ikoreshwa rya carburizing agent, ugomba kwita ku kibazo
Iyo igihe cyo kongeramo icyuma gitera kaburimbo kiri kare cyane, biroroshye kugihambira hafi y’itanura, kandi icyuma gitera kaburimbo gifatanye n’urukuta rw’itanura ntibyoroshye kwivanga mu cyuma gitemba. Ahubwo, kongeramo igihe bitinze, bizatakaza amahirwe yo kongeramo karuboni, bigatuma igihe cyo gushonga no gushyuha gitinda. Ibi ntibitinza gusa igihe cyo gusesengura no guhindura imiterere y’imiti, ahubwo binateza ingaruka mbi ziterwa no gushyuha cyane. Kubwibyo, icyuma gitera kaburimbo cyangwa kiri mu nzira yo kongeramo icyuma gishyushya buhoro buhoro kugira ngo gihuzwe.
Nk’uko bigenda mu gihe cy’inyongera nyinshi, ishobora guhuzwa n’itanura ry’inyongera iyo icyuma gishyushye cyane gikozwe mu buryo bw’amazi, kugira ngo igihe cyo kwinjiza icyuma mu mazi cya 10Min, ku ruhande rumwe binyuze mu buryo bwo gukurura amashanyarazi bwa carburizer bukwirakwira neza, kugira ngo ingaruka zo kwinjiza zigerweho. Ku rundi ruhande, ingano ya azote yinjizwa muri carburizer ishobora kugabanuka.
Ntugashyiremo rimwe, shyiramo uduce duto, hanyuma ushonge igice, shyira igice cy'icyuma gishyushye (kigera ku gapaki) mu gikapu, hanyuma usubize muri kaburizeri y'itanura inshuro 1-2, hanyuma ushyiremo slag, ushyiremo alloy.
Hari ibintu byinshi byo kwitaho:
1. Ingufu zituma umuntu arya kaburimbo zigorana kuzikura (nta gukaraba);
2, ikwirakwizwa ry'uduce tw'ivu rikoreshwa mu gukaraba ntabwo ringana;
3. Kwinjira byatinze cyane;
4. Uburyo bwo guhuza ntabwo ari bwo bwiza, kandi hakoreshwa uburyo bwo guhuza ibintu mu byiciro. Irinde indorerwamo y'icyuma gikozwe mu mazi n'ibisigazwa byinshi iyo byongewemo;
5. Gerageza kudakoresha ibikoresho byinshi byangiritse.
Ibiranga ibikoresho byo kugabanya ubushyuhe mu mubiri (carburizing agent)
1, ingano y'uduce ni iringaniye, imiterere y'uturemangingo ni minini, umuvuduko wo kwinjiza ni wihuta.
2. Imiterere y’imiti isanzwe, karubone nyinshi, sulfure nkeya, ibice bito cyane byangiza, igipimo cyo kwinjiza ibintu kinini.
3, imiterere ya kristale ya grafiti y'ibicuruzwa ni myiza, yongera ubushobozi bwo guteranya icyuma cy'amazi. Ongera umubare w'udusimba tw'icyuma mu gutera, kandi wongere nucleus ya grafiti mu cyuma cy'amazi gikoresha amashanyarazi. Kunoza no gukwirakwiza wino y'ibisigazwa mu byuma bicukurwamo.
4. Imikorere myiza cyane no kudahungabana.
Guhitamo uburyo bukwiye bwo gushongesha ibintu bikozwe muri kaburimbo bifasha kugabanya ikiguzi cyo gukora ishongesha ibintu, kunoza ubwiza bw'ibyuma bishongesha ibintu n'ibikoreshwa mu gushongesha ibintu, bityo uruganda rushongesha ibintu, n'ibikoreshwa mu gushongesha ibintu.
