Ibihe bigezweho hamwe nicyerekezo cyiterambere cyo gutwara ibyuma

Imyenda ikoreshwa cyane mu mashini zicukura amabuye y'agaciro, ibikoresho bya mashini zuzuye, ibikoresho bya metallurgjiya, ibikoresho biremereye hamwe n’imodoka zo mu rwego rwo hejuru hamwe n’ibindi bikoresho bikomeye, kubyara ingufu z'umuyaga, gari ya moshi yihuta cyane na gari ya moshi hamwe n’inganda n’izindi nganda zigenda ziyongera.Ibicuruzwa byakorewe mu Bushinwa ni cyane cyane ibyuma bito bito hamwe na bito bito n'ibiciriritse, byerekana ibicuruzwa bisagutse byo hasi hamwe no kubura kurwego rwo hejuru. Ugereranije nibihugu byamahanga, hariho icyuho kinini mumitambiko yo hejuru kandi nini.

Ubushinwa bwihuta bwimodoka itwara abagenzi idasanzwe ihuza ibiziga byose bigomba gutumizwa mu mahanga.Mu bikoresho byingenzi bikoreshwa mu kirere, gari ya moshi yihuta, imodoka zo mu rwego rwo hejuru ndetse n’indi nganda, hari itandukaniro rinini hagati y’Ubushinwa na Iterambere mubyerekeranye nubuzima bwa serivisi, kwizerwa, agaciro ka Dn nubushobozi bwo gutwara.Urugero, ubuzima bwa serivise yimodoka yohereza mumodoka byibura kilometero 500.000, mugihe ubuzima bwumurimo wibikoresho bisa murugo bingana na kilometero 100.000, kandi kwiringirwa no ituze rirakennye.

1. Indege

Nkibice byingenzi bigize moteri ya aero, moteri ya kabiri ya aero-moteri ifite igipimo cya 15-20 itezwa imbere mumahanga, yiteguye gukusanyirizwa mumurwanyi wa gatanu mumwaka wa 2020.Mu myaka 10 ishize, Reta zunzubumwe zamerika zateje imbere igisekuru ca kabiri gitwara ibyuma bya moteri ya aero-moteri, ubwoko bwibyuma bihagarariye ni CSS-42L, imbaraga zikomeye zo kwangirika kwangirika kwicyuma gifite 500 ℃, na X30 (Cronidur30), azote irwanya ruswa irwanya ibyuma hamwe 350 ℃ kurwanya.Ubushinwa butezimbere igisekuru cya kabiri cyitwa aero-moteri.

2. Imodoka

Kubinyabiziga bitwara ibinyabiziga, icyuma cya mbere nicyakabiri cya hub hub (imipira yumupira) bikoreshwa cyane mubushinwa, mugihe ibyiciro bya gatatu bya hub byakoreshejwe cyane muburayi. .

3. Ibigega bya gari ya moshi

Kugeza ubu, ibyuma bikoreshwa muri gari ya moshi ziremereye mu Bushinwa bikozwe muri electroslag yo mu gihugu ikuraho ibyuma bya karubasi ya G20CrNi2MoA. Kandi umunyamahanga afite ubwiza buhebuje bwo gutwara ibyuma (EP) gushonga ibyuma hamwe na vacuum bitesha agaciro ikoranabuhanga rya homogenisation (IQ), ubuzima burebure ibyuma bya tekinoroji (TF) ibyuma, ubuziranenge bwiza, hamwe nubuhanga bwo gutunganya ubushyuhe, tekinike yo kuvura hejuru hamwe nubuhanga buhanitse bwo gusiga amavuta bikoreshwa mubikorwa byo kubyara no gukora, bityo bikazamura cyane ubuzima bwa serivisi yo kubyara no kwizerwa. Ubwiza bwa electroslag yo mubushinwa ibyuma ntabwo biri hasi gusa, ariko kandi ikiguzi ni 2000-3000 yuan / toni kurenza icyuma cyangiza.Mu bihe biri imbere, Ubushinwa bugomba guteza imbere icyuma cyangiza icyuma gifite ubuziranenge buhebuje, ubwiza bwiza, ubutinganyi hamwe n’ubuziranenge buhamye kugira ngo busimbuze imikoreshereze y’icyuma cya electroslag.

Icyerekezo kizaza hamwe niterambere ryicyuma cyo gutwara ibyuma mubushinwa

Bigaragarira cyane cyane mubice bine:

1. Isuku mu bukungu

Hashingiwe ku gutekereza ku bukungu, isuku y’ibyuma irusheho kunozwa, ibirimo ogisijeni na titanium mu byuma bigabanuka, kandi igice kinini cya ogisijeni na titanium mu gutwara ibyuma kiri munsi ya 6 × 10-6 na 15 × 10- 6.Ibirimo nubunini bwibyuma mubyuma biragabanuka, kandi gukwirakwiza uburinganire biratera imbere.

2. Gutunganya imitunganyirize no guhuza ibitsina

Binyuze mu gukoresha ibishushanyo mbonera no kugenzura gukonjesha no kugenzura uburyo bwo gukonjesha, uburinganire bwibintu hamwe na karbide birarushaho kunozwa, karbide ya reticulée na bande iragabanuka kandi ikavaho, ingano yikigereranyo nubunini bwa karbide iragabanuka, nubunini buringaniye bwa karbide ni munsi ya 1μ m. Ingano yintete yo gutwara ibyuma iranonosorwa mugutezimbere ingano yimiterere ya matrix.

3. Kugabanya inenge zingufu zingirakamaro

Komeza ugabanye icyerekezo cyo hagati, kugabanuka hagati hamwe no gutandukanya ibice hagati mugutwara ibyuma, kunoza uburinganire bwimbaraga nke.

4. Gukomera gukomeye kwicyuma

Ubukomezi bwo gutwara ibyuma byatejwe imbere nubushakashatsi bushya, uburyo bwo gushyushya ibintu hamwe nubushakashatsi bwo gutunganya ubushyuhe. (China Steel Research & Development Strategy Institute)

Inshingano: ibikoresho bishushanyo bivuye kumurongo, uburenganzira bwumwanditsi kubwumwimerere byose, nko kurenga, nyamuneka hamagara kugirango usibe.
