Ubutandukane mu mikorere y'ubwenge
Cr15: Ivyuma bifise chromium bike cane bifise carbures bike cane. Ubukomezi buke gatoyi ariko igiciro c’ibikoresho vya mbere kiri hasi cane. Ni vyiza ku bihe vy'akazi bifise ububabare buke -bifise igiciro ca mbere.
Cr20: Urugero rwa chromium ruringaniye n’ubudandaji bwiza-off hagati y’uguhangana n’ugusambuka, ubukomezi n’igiciro. Ivyo bikoresho vy’imbere mu nzu vyemewe cane mu bikorwa vy’ubucukuzi bw’amabuye y’agaciro.
Cr26: Igitigiri kinini c’ivyuma vyitwa chromium kirongera cane igipimo ca carbide, kigatanga ubukomezi bwo hejuru-tier, ubushobozi bwo guhangana n’ugusambuka, ubushobozi bwo guhangana n’ubushuhe bwinshi n’ubushobozi bwo guhangana n’ugusenyuka kw’aside{3}}alkali. Intambamyi yonyene ni igiciro kinini c’ibikoresho vya mbere.
3. Uburyo busanzwe bwo gusukura ubushuhe (buhambaye ku buzima bw'ibikorwa)
Uburyo bwo kuzimya no gutera umuriro bushitse ni ngombwa ku bikoresho vy’ivyuma vy’agaciro kanini. Nk’uko-ibikoresho vy’ugucukura bishika gusa kuri HRC40~46, n’ubushobozi bwo guhangana n’ugusambuka buri munsi ya 60% vy’ibikoresho vy’ubushuhe-vyiza.
Cr15 (KmTBCr15Mo) Guzimya: Gufata ku bushuhe bwa 940~980 amasaha 2~4, gukonjesha n'ikizimya kigenewe; Gushushanya: Gushushanya ubushuhe buke-ku 220~280 degrees amasaha 3~6 kugira ngo umuntu akureho umubabaro wo mu mutima; Ubukomezi bwa nyuma HRC Burengeye canke bungana na 59.
Cr20 (KmTBCr20Mo) Guzimya: Gufata ku bushuhe bwa 980~1030 amasaha 2~5; Ubushuhe: Ubushuhe buke-ubushuhe ku 230~290 degre ; Ubukomezi bwiza cane HRC60 ~ 62.
Cr26 (KmTBCr26) Guzimya: Gufata ku bushuhe bwa 1010~1060 amasaha 3~6 kugira ngo bishiremwo neza ivyuma vy’ivyatsi bibiri; Gutera: Gufata ku bushuhe bwa degre 250~300 amasaha 4~8; Ubukomezi buhamye hejuru ya HRC62. Ubushuhe bwo gushushanya bushobora kuduzwa gatoyi ku bikorwa vy'ubushuhe bwinshi-kugira ngo ubushuhe bube buhagaze.
Ivyiyumviro: Gukonjesha umuyaga kamere no gukonjesha hejuru ya degre 400 birabujijwe cane, ivyo bikaba bigabanya cane ubukomezi n’ubushobozi bwo guhangana n’ugushaza.
4. Ivyangombwa vy'akazi, ibikoresho n'ibikoresho ku rwego rwose rw'indege
4.1 Cr15 Igikoresho gikomeye ca Chromium (Ikigero c'ubutunzi)
Ivyo bishobora gukoreshwa: Insyo z’umupira zifise uburebure buto, ibikoresho vyoroshe, ibikorwa bigenda bihinduka Ibikoresho: Insyo nto z’umupira Φ Ziri munsi canke zingana na 2,4m, insyo z’amakara, ibikoresho bitobito vyo gusenyura umusenyi, ibinogo vy’amabuye y’agaciro gatoyi n’ibindi bikoresho: medium{3}}low hardness ores Ivyiza: Igiciro gitoyi co kugura, uburemere buke, amahera make yo gusubirira Inyungu: Ubuzima bugufi bw’ibikorwa munsi y’amabuye y’agaciro menshi-n’ugukomeza gukora kwuzuye-; Ntibibereye gusya amazi n’amazi y’aside Ubuzima bwitezwe: imyaka 3 ~ 5, bingana gusa na 60% ~ 70% vy’ubuzima bw’ibikoresho vy’i Cr20 mu bihe bisa
4.2 Cr20 Igikoresho gikomeye ca Chromium (Igitigiri c'Isi Yose, Umugabane w'Isoko Munini)
Ivyiyumviro bishobora gukoreshwa: Gushaza hagati, ivyumye n'ibitose bibiri-intumbero, uburyo busanzwe bwo gukora simenti/ubucukuzi, uburinganire bwo guhangana n'ugusaza n'igiciro Ibikoresho: Φ2.4~3.6m insyo z'ifu y'ibitoke, insyo z'amabuye y'agaciro, insyo z'umupira w'ivyuma, insyo z'umupira w'amabuye y'agaciro, ivyuma vy'imbere vy'isima {{0}lo: Granite, ivyuma, umusenyi wa quartz, clinker ya simenti, ibuye ry’umusenyi ry’ivyuma Ivyiza: Ushobora guhangana n’ugusaza n’ugukomera, guhangana n’ibintu bikomeye, guhuye n’ugusya kwumye n’ugutose, ubushobozi bwiza bwo gusya Inyungu: Ni hasi y’ibikoresho vya Cr26 biri munsi y’amabuye y’agaciro akomeye cane {basature} n’amabuye y’agaciro akomeye cane. Ubuzima bwitezwe: Imyaka 5 ~ 8, incuro 1.5 ~ 1.8 kurusha Cr15 liners
4.3 Cr26 Igikoresho co mu bwoko bwa Chromium (Igikoresho co mu bwoko bwa Chromium gikomeye -Igikoresho co guhangana n'ugushaza cane)
Ivyo bishobora gukoreshwa: Ugushaza cane, ubushuhe bwinshi, ivyuma vy’aside, insyo nini-y’uburebure, gukomeza gukora n’ibikoresho vya mbere bikomeye cane Ibikoresho: Insyo nini zikora amabuye y’agaciro Φ Zirengeye canke zingana na 3.6m, insyo zihagaze z’uburebure bw’uburebure bw’uburebure, insyo zihagaze. chutes, ibikoresho vy'ugusya vy'amazi vyinshi-vy'ubumara Ibikoresho vya mbere: Basalt, ubushuhe bwinshi-silicon quartz, ivyuma bikomeye, ubushuhe bwinshi-ex clinker, sulfur-irimwo aside slurry Inyungu: Uguhangana n'ugushaza kw'imbere, uguhangana n'ubushuhe bwinshi{8}} ubushobozi bwo kuruha n’ubushuhe, butagiramwo ugusambuka kw’imirongo vyihuta Inyungu: Igiciro kinini co kugura imbere y’igihe; Ivyuma vy'amanganese vy'uruhome rwinshi cane bishobora gukoreshwa cane n'ibikoresho vyinshi cane.
5. Ubuhinga bwa Liner n'ubuhinga bwo gutera urufunguzo
Uburyo bwo guhingura: Gutakaza ifu y’ukuri canke gutera umusenyi w’ivyuma kugira ngo haboneke ivyuma vy’imipfunda, ivyuma vy’uguterura biteye intambwe, ivyuma vy’imipfunda n’ivyuma vy’ugupfuka iherezo. Ibikoresho vya Cr26 birafise urugero runini rwo gucika, ni co gituma ibibumbano bisaba ko umuntu agira amahera menshi yo gucika.
Igishushanyo co kurwanya-ugusaduka: Ivyuma bifise uburebure burenze 60mm bifatanywa na molybdenum na vanadium kugira ngo bitunganye imiterere y’intete. Ivyuma bikonja vyo mu mutima bishirwa ku bikoresho bininibinini kugira ngo ntihagire carbide itandukana n’ugusenyuka.
Gushiraho Guhuza: Imyobo y'amabouti yabitswe mbere-kugira ngo isubirizwe igice kimwe -. Ugereranije n’ivyuma vy’ivyuma vyinshi vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma bishobora kuba 15% ~ 25% vy’ivyuma bifise ubushobozi bwo guhangana n’ugusambuka, bikagabanya umuzigo w’insyo n’inguvu zikoreshwa.

7. Ivyiyumviro vyo gukoresha no gucungera
Ingaruka: Ivyo bipimo vyose bitatu ni ibikoresho bishobora guhangana n’ingaruka ziri hagati- zidashobora gusenyuka. Ku bikoresho vyo gusya bikomeye bifise ubunini bw’ibifungurwa birenze 100mm, ivyuma vy’ivyuma vy’i manganese canke ivyuma vy’ivyuma bibiri vy’ivyuma bibiri ni vyo bishirwa imbere kugira ngo ivyuma vy’ivyuma vy’i chromium ntibimeneke.
Ibidukikije bishobora gutera uburozi: Cr26 ni ngombwa ku mavuta y’ikibiriti-arimwo n’ay’amazi y’aside; Cr15 irashikirwa n’ugusenyuka kw’ibitobo (pitting corrosion) ivyo bikaba vyihuta gusenyuka.
Ubushuhe Bugabanywa: Cr26 yonyene ni yo iguma ikora neza mu gihe c'ubushuhe burengeye degre 350. Igihe kirekire-ubushuhe bwinshi-igikorwa kiyorosha Cr15 biciye mu gukosora, kigatuma ukubura kwambara gukubita kabiri.
Gushiramwo no Gucungera: Gusudira no guca ivyuma vy’ivyuma vy’agaciro kanini birabujijwe, kuko gusudira mu bushuhe bwinshi-bitera imivyimba. Uzuza ibihengeri hagati y'ibipfukisho n'ibikoresho bishobora guhangana n'ugusambuka-mu gihe co gushiramwo kugira ngo wirinde gusenyuka kw'ibikoresho ku mabuye.
8. Incamake y'igiciro n'inyungu zose
Cr15: Ishoramari ry’imbere ry’igihe ritoyi cane ariko ryihagarara kenshi kugira ngo risubirizwe. Ibereye amahinguriro mato-ashobora gutakaza igihe gito co guhagarara.
Cr20: Igiciro ciza muri rusangi, imiterere isanzwe y’ibigo vya simenti 80% n’amamine mato mato ari hagati-.
Cr26: Igiciro c'amasoko y'incuro imwe-kirengeye ariko n'ingendo yo gusubirira incuro zibiri. Igiciro gitoyi co gukoresha no gucungera imirongo minini y’ibikorwa ikomeza, bikagabanya cane ibihombo vy’ubutunzi bitewe n’igihe c’uguhagarara kw’ibikorwa.
