Impamvu iyi Ubuyobozi ihari (n'impamvu ugomba kubyitaho)
Niba warigeze kugura inkono y'amazi, uzi imyitozo: abatanga serivisi bakoherereza ibiciro bifite ireme ry'ibikoresho, wenda urupapuro rw'amakuru rw'ipaji imwe, n'isezerano ry'uko "iri ari ryo remezo ryiza ku itanura ryawe." Ariko iyo inkono icitse nyuma y'amezi 18, uwo mutanga serivisi avuga ati "imikorere yawe irakomeye cyane."
Twanditse iyi nyandiko kuko tubona urujijo buri munsi. Abayobozi b'inganda baratubaza bati:
● Ni irihe tandukaniro nyaryo riri hagati ya ZG270-500 na GS-20Mn5?
● Kuki ASTM A27 60-30 ihendutse ariko ikaba ifite imbaraga nke zo gutanga umusaruro?
● Ese nshobora gukoresha ibikoresho bimwe mu nkono za EAF na BOF slag?
Iyi mfashanyigisho iguha ibisubizo byumvikana - nta buswa bwo kwamamaza, nta gahunda ihishe. Tuzagereranya ibikoresho bitatu bikunze gukoreshwa mu nkono y'ibisuguti, tukubwire aho buri kimwe gikora neza, n'aho kinanirwa.
*Icyitonderwa: Ibi bishingiye ku bunararibonye bw'imyaka irenga 20 bwa Womic Steel mu gushushanya no ku bitekerezo byatanzwe n'inganda zirenga 200 z'ibyuma ku isi yose. Imiterere yawe yihariye y'imikorere ishobora gutandukana.*

| Molybdenum (Mo) | Ntabwo byagaragajwe | ≤0.10% | Ntabwo byagaragajwe |
Icyo ibi bivuze mu buzima busanzwe:
●Karuboni nke muri GS-20Mn5(0.18-0.23%) bivuze ko ubushobozi bwo gusudira neza no gukomera cyane, cyane cyane iyo ubushyuhe buri hasi. Binagabanya ibyago byo kwangirika kwa hydrogen.
●P na S bikomeye kurushahomuri GS-20Mn5 bigabanya ubushyuhe bukabije kandi bikongera ubushobozi bwo kugenda neza. Ibi ni ingenzi iyo inkono yawe y'ibisuguti ishyushye kandi ikonjeshwa kenshi - umwanda muke utuma iramba.
●Nta Cr/Ni/Mo yagenweMuri ZG270-500 na ASTM A27 bivuze ko uruganda rushobora gukoresha icyuma cya karuboni gikozwe mu buryo bwa alloy. Ibyo ni byiza mu bihe byoroheje, ariko ntabwo ari byiza mu gihe cy’ubushyuhe budashobora kwihanganira umunaniro.

Noneho reka dusobanure iyi mbonerahamwe ku mikorere yawe ya buri munsi:
●Imbaraga z'umusaruro– GS-20Mn5 ifite umusaruro mwinshi (300 vs 270 MPa), bityo irwanya guhinduka kw'amazi mu gihe cy'imizigo iremereye y'ibitaka. Ibi bigaragara iyo urenze urugero mu nkono cyangwa iyo icyuma gikoresha crane gikaze.
●Kurekura– ASTM A27 ifite uburebure bwinshi (24% ugereranije na 18%), bivuze ko ishobora kurambura cyane mbere yo kuvunika. Ariko mu nkono z'ibitaka, uburebure buri hejuru ya 18% ntabwo ari cyo kintu kigabanya ubushyuhe – umunaniro ukabije ni wo utuma ibintu birushaho kugorana.
●Ubukomere bw'ingaruka– Iyi ni yo ikomeye. GS-20Mn5 ikunze gupimwa ku gipimo cya -20°C. Niba uruganda rwawe ruri muri Siberiya, mu majyaruguru ya Kanada, cyangwa ndetse no mu majyaruguru y'Ubushinwa mu gihe cy'itumba, ibi ni ingenzi. ZG270-500 na ASTM A27 bishobora kwangirika iyo ubushyuhe buri munsi ya zeru.
l *Inkuru nyayo: Imashini ikora uruganda muri Mongolia y'imbere yakoresheje inkono za ZG270-500. Muri Mutarama, ubushyuhe bwo hanze -25°C, inkono yacitse mu gihe cy'umunsi wa mbere. Bahinduye GS-20Mn5 - nta gucika kw'imbeho ukundi.*
Ikiguzi ugereranije n'imikorere - Ni iyihe iguha inyungu nziza kurusha izindi?
Twakurikiranye amakuru y'ibiciro n'ubuzima bw'inganda 47 z'ibyuma mu myaka 5 ishize. Dore ibyo twabonye:
| Icyiciro | Igiciro cy'Icyiciro cya Mbere | Impuzandengo y'ingendo kugeza ku gutsindwa | Igiciro kuri buri ruziga 1.000 |
| ZG270-500 | Umurongo w'ibanze | Igare 4.200 | $X (ibanze) |
| ASTM A27 60-30 | + 10-15% | Igare 4,500 | 0.95X |
| GS-20Mn5 | +40-60% | Igare 7,500 | 0.85X |
Imibare ni ikimenyetso - urugendo rwawe rushobora gutandukana bitewe n'imiterere y'imikorere.
Isomo ritangaje:Nubwo igiciro cya mbere kiri hejuru, GS-20Mn5 ikunze gutangaigiciro gito cyane kuri buri ruzigakuko imara hafi kabiri y’igihe. Ariko hari ikibazo: isaba ubushyuhe bukwiye (buzimye + bushyushye). Hari abakora ubwubatsi bavuga ko batanga GS-20Mn5 ariko batanga ibikoresho bisanzwe gusa - bitazaguha ubuzima nk’ubwo.
Igihe cyo gukoresha ZG270-500:
● Igikorwa cyawe ni gito (nta gushyuha gukabije)
● Ntukora munsi ya 0°C
● Ufite ingengo y'imari nto kandi ushobora kwemera igihe gito cyo kubaho
● Usimbura inkono buri myaka 2-3 uko byagenda kose
Igihe cyo gukoresha ASTM A27 60-30:
● Ibisobanuro by'umushinga wawe bisaba ko ibikoresho bya ASTM bitangwa
● Ugomba guhaza ikigo cy’ubwubatsi cyo muri Amerika cyangwa inguzanyo
● Ntabwo ushaka kwishyura GS-20Mn5 premium ariko ushaka inyandiko nziza gato kurusha ZG270-500
Igihe cyo gukoresha GS-20Mn5:
● Ukora amasaha 24/7, ufite ubushyuhe bwinshi (EAF cyangwa LF ikoreshwa kenshi)
● Ubushyuhe bw'ikirere cyawe bugabanuka munsi y'ubukonje
● Urashaka igiciro gito cyane cy'igihe kirekire kuri toni y'icyuma gikorerwamo
● Ukeneye icyemezo cy'i Burayi (PED, EN 10204 3.2)
Ibitekerezo Bisanzwe Bitari byo – Ibyo Twumva Biturutse ku Bakiriya
Igitekerezo cya 1: "Imbaraga nyinshi zo gukurura buri gihe bivuze ko icyuma gikoreshwa mu gukurura ibintu gikozwe mu ibumba cyiza."
Si ukuri. Ingufu zo gukurura zirenze 450 MPa ntizikunze gukoreshwa mu gutanga ibikoresho byo gukurura. Igica inkono ni umunaniro w'ubushyuhe n'ingaruka, ntabwo ari ugukomera kw'umwuka gusa. GS-20Mn5 ifite imbaraga zo gukurura nkeya ugereranyije na ZG270-500 ariko irwanya umunaniro neza cyane.
Igitekerezo cya 2: “Uruganda urwo ari rwo rwose rushobora gukora GS-20Mn5 – ni ikintu gisanzwe.”
Ntibikwiye. GS-20Mn5 isaba ubushyuhe buhagije: kuzimya (amazi cyangwa umwuka uhatirwa) no gushyushya. Inganda nyinshi zikora ibyuma zisimbuka intambwe yo kuzimya hanyuma zigasubiramo ibintu bisanzwe. Ubona imiterere ya GS-20Mn5 ariko ZG270-500. Saba inyandiko zo kuvura ubushyuhe n'imiterere y'ubukomere.
Igitekerezo cya 3: “Twakoresheje ZG270-500 buri gihe kandi nta kibazo.”
Ikibazo kimwe: ese uzi ko imikorere yawe ya cycles igenda inanirwa? Imashini nyinshi zera ko cycles 3.000 ari "nziza" - ariko ushobora kubona cycles 7.000 hamwe n'igikoresho cyiza kurushaho. Birakwiye kubara ikiguzi cyawe cyihishe cyo gusimbuza hakiri kare no kudakora.
Icyo wabaza umucuruzi wawe w’inkono y’ibishishwa (Urutonde rw’ibyo ugomba gukora)
Mbere yo kurangiza gutumiza, ibaze ibi bibazo - ibisubizo bizakubwira niba umutanga ibicuruzwa azi ibyo acuruza.
1."Ni uruhe rugero rw'ubumenyi bw'imiti ukoresha kuri iyi shami, ntabwo ari imbibi zisanzwe gusa?"
Umutanga serivisi mwiza azaguha ingano nto (urugero: C: 0.30-0.35%, ntabwo ari 0.30-0.40%).
2."Ese ukora isuzuma ry'ingaruka kuri 0°C cyangwa -20°C? Ushobora kunyereka ibisubizo?"
Kuri ZG270-500, abatanga ibicuruzwa benshi ntibagerageza ingaruka na gato. Kuri GS-20Mn5, -20°C ni ibisanzwe.
3."Ni iyihe gahunda yawe yo kuvura ubushyuhe kuri iki gikoresho?"
Bisobanure neza: ubushyuhe bwo kongerera imbaraga, igihe cyo koga kuri santimetero imwe, uburyo bwo kuzimya, ubushyuhe bwo kongerera imbaraga n'igihe.
4."Ese ufite raporo y'ikizamini cy'ubushyuhe bwangiza kuri iki gikoresho?"
Abakora ubwubatsi bake cyane ni bo bakora ibi. Womic Steel itanga imwe iyo bayisabye.
5."Ese ushobora gutanga ikarita y'ubugari bw'inkuta ukoresheje raporo ya ultrasound?"
Ibi bituma habaho ubugari bumwe - ubusembwa busanzwe bwihishe mu nkono z'ibirungo.
Icyifuzo cya nyuma
Ku nganda nyinshi ziciriritse ziri mu kirere kiringaniye:Tangira na ZG270-500. Ihendutse kandi ikora akazi. Ariko sababisanzwe hamwe n'ibyizaGutunganya ubushyuhe - abatanga serivisi benshi babikora gusa, ibyo bigabanya ubukana.
Ku nganda zifite ubukonje bw'imbeho cyangwa zikora kenshi:Ishoramari muriGS-20Mn5ifite imiterere yazimye kandi ishyushye. Amafaranga y'inyongera yishyurwa mbere y'igihe mu myaka 2 binyuze mu gusimbuza bike no kugabanya igihe cyo kuruhuka.
Ku mishinga ijyanye na Amerika:ASTM A27 60-30 ni amahitamo yizewe. Ariko, niba imikorere yawe isaba imbaraga nyinshi, vugurura ukoreshe ASTM A27 65-35 (umusaruro mwinshi).
Icyo wahisemo cyose, andika byose mu nyandiko.Urusobe rw'imiti, uburyo bwo kuvura ubushyuhe, uburyo bwa NDT, n'ibipimo byo kwemerwa - ntibisiga umwanya wo kubisobanura.
Uracyari mu kajagari? Reka tuvuge ku mikorere yawe yihariye
Buri ruganda rw'icyuma ruratandukanye. Dushobora gusuzuma imikorere y'inkono yawe ya slag ubu - imikorere kuva ku gutsindwa kugera ku gutsindwa, amafoto y'uburyo yangiritse, ubushyuhe bw'imikorere, n'ubushobozi bwa crane - hanyuma tukakugira inama yo gukoresha ibikoresho n'igishushanyo mbonera cyiza.
