Igiciro cyo Kugabanuka 20CrNiMo Umuyoboro wa Alloy Steel
Ibisobanuro bigufi:
20CrNiMo nicyuma cyiza cyane kivanze nicyuma cyububiko gifite ibikoresho byiza bya mashini, birwanya ruswa kandi birwanya kwambara.Ikoreshwa cyane mumashini, ubwubatsi, ubwubatsi no kurengera ibidukikije.Imbaraga zacyo nyinshi, gukomera no guhindagurika bituma ituma ubuzima bumara igihe kirekire mubidukikije kandi bikarwanya imitwaro myinshi, bitanga inkunga ikomeye mugutezimbere inganda nubuhanga bugezweho.
Gushyigikirwa nitsinda ryitumanaho ryateye imbere kandi ryinzobere, dushobora gutanga inkunga ya tekiniki mbere yo kugurisha & nyuma yo kugurisha kugiciro cyo kugabanura 20CrNiMo Ikidodo cya Alloy Steel Pipe, Tugiye kwihatira gukomeza umwanya ukomeye nkumushinga utanga ibisubizo byiza cyane. mw'isi.Mugihe ufite ikibazo cyangwa igitekerezo icyo ari cyo cyose, menya neza kutwandikira mubuntu.
Gushyigikirwa nitsinda ryateye imbere cyane kandi ryinzobere mu IT, dushobora gutanga inkunga ya tekiniki mbere yo kugurisha & nyuma yo kugurisha kuriUbushinwa 20CrNiMo Alloy Ikidodo Cyuma Cyuma, Akazi gakomeye kugirango ukomeze gutera imbere, guhanga udushya mu nganda, kora ibishoboka byose kugirango umushinga wo mucyiciro cya mbere.Turagerageza uko dushoboye kugirango twubake uburyo bwo kuyobora siyanse, twige ubumenyi bwinshi bwumwuga, dutezimbere ibikoresho byumusaruro bigezweho hamwe nuburyo bwo kubyaza umusaruro, gukora ibicuruzwa byambere byita ibicuruzwa byiza, igiciro cyiza, serivisi nziza, gutanga byihuse, kugirango tuguhe guhanga agaciro gashya.

20CrNiMo yabanje kuba ibyuma nimero 8620 mubipimo bya AISI byabanyamerika na SAE.Imikorere yo gukomera isa niy'icyuma cya 20CrNi.Nubwo Ni ibirimo mubyuma ari kimwe cya kabiri cyicyuma cya 20CrNi, bitewe no kongeramo umubare muto wa Mo element, igice cyo hejuru cya austenite isothermal ihinduka umurongo ujya iburyo;kandi kubera ubwiyongere bukwiye bwibirimo Mn, gukomera kwiki cyuma biracyari byiza cyane, nimbaraga Nayo irarenze ibyuma 20CrNi, kandi irashobora kandi gusimbuza ibyuma 12CrNi3 kugirango ikore ibice bya karubone nibice bya cyanide bisaba imikorere yibanze.20CrNiMo irashobora kwihanganira ubushyuhe runaka hiyongereyeho ibintu byiza byuzuye kuko irimo molybdenum.
1. Mu nganda zikora, akenshi zikoreshwa mugukora ibice biterwa numutwaro mwinshi, guhangayika cyane, no kwambara cyane, nka gare, shitingi, ibyuma, nibindi. Imbaraga zabo nyinshi hamwe nubukomezi bwiza bituma ibyo bice bikomeza igihe kirekire cyakazi mubuzima bubi bukora.Byongeye kandi, ifite kandi imbaraga nziza zo kurwanya umunaniro no kurwanya ruswa, ishobora kurwanya neza isuri y’ibidukikije kandi ikanakora neza ibikoresho.
2. Mu rwego rwubwubatsi, iki cyuma gikoreshwa cyane mukubaka inyubako nini nkikiraro ninyubako ndende kubera imbaraga nyinshi kandi zihindagurika.Muri izi nyubako, zirashobora guhangana n’umuvuduko mwinshi n’impagarara, bikarinda umutekano n’inyubako.
3. Byongeye kandi, hamwe no kunoza imyumvire y’ibidukikije, gusaba mu rwego rwo kurengera ibidukikije bigenda byiyongera.Kurugero, mumodoka nshya yingufu, irashobora gukoreshwa mugukora ibice byingenzi nka moteri na kugabanya, bigira uruhare mubyatsi.Ifite kandi uruhare runini mu bikoresho byo kurengera ibidukikije nko gutunganya imyanda no gutunganya imyanda, itanga inkunga ikomeye mu kuzamura ireme ry’ibidukikije.
1. Ibikoresho byingenzi byubatswe, nkibikoresho byo kuguruka byindege, tank hamwe nibikoresho byimodoka.
2. Imbaraga zikomeye zifata kandi zihuza.
3. Ibikoresho biremereye cyane.
Kuzimya 850ºC, ubukonje bwamavuta;Ubushyuhe 200ºC, gukonjesha ikirere.
Gutanga mu kuvura ubushyuhe (bisanzwe, annealing cyangwa ubushyuhe bwo hejuru) cyangwa nta buryo bwo kuvura ubushyuhe, imiterere yo kubyara igomba kugaragazwa mumasezerano.
Gushyigikirwa nitsinda ryateye imbere kandi ryinzobere, dushobora gutanga inkunga ya tekiniki mbere yo kugurisha & nyuma yo kugurisha.

Tugiye kwihatira gukomeza umwanya ukomeye nkumuti mwiza utanga ibisubizo kwisi.Mugihe ufite ikibazo cyangwa igitekerezo icyo ari cyo cyose, menya neza kutwandikira mubuntu.
Ubushinwa 20CrNiMo Alloy Ikidodo Cyuma Cyuma
Akazi gakomeye kugirango ukomeze gutera imbere, guhanga udushya mu nganda, kora ibishoboka byose kugirango umushinga wo mucyiciro cya mbere.Turagerageza uko dushoboye kugirango twubake uburyo bwo kuyobora siyanse, twige ubumenyi bwinshi bwumwuga, dutezimbere ibikoresho byumusaruro bigezweho hamwe nuburyo bwo kubyaza umusaruro, gukora ibicuruzwa byambere byita ibicuruzwa byiza, igiciro cyiza, serivisi nziza, gutanga byihuse, kugirango tuguhe guhanga agaciro gashya.
