Zikafika pa Mipeni ya ku Japan, aliyense amangoyang'ana mtundu wa mpeni ndi zomwe umagwiritsidwa ntchito koma palibe zambiri zokhudzana ndi zomwe zitsulo zimagwiritsidwa ntchito popanga.

Mitundu yachitsulo yaku Japan yakhala yofunika nthawi zonse, makamaka popanga lupanga.

Katana waku Japan ndi chitsulo champhamvu chomwe chimapyoza chilichonse. Japan mkulu carbon steel ndi nkhani ina yonse - imagwiritsidwa ntchito popanga mipeni yabwino kwambiri yakukhitchini.

Chitsulo chabuluu ndi chitsulo choyera ndi mitundu yachitsulo yaku Japan yomwe imagwiritsidwa ntchito popanga mipeni.

Aogami ndi mawu oti chitsulo cha pepala cha buluu pomwe shirogami amatanthauza chitsulo cha pepala loyera. Mitundu iwiriyi yazitsulo imakhala ndi mitundu yosiyanasiyana ya mankhwala ndi mpweya wa carbon koma onse ndi mitundu ya zitsulo za carbon. Aogami imagwira bwino m'mphepete mwake pomwe shirogami ili ndi tsamba lakuthwa.

Mipeni yambiri ya ku Japan imapangidwa ndi chitsulo chabuluu kapena chitsulo choyera. Kotero, ngati mukudabwa chomwe chimapangitsa mipeni yanu yakukhitchini yaku Japan kukhala yapadera komanso yakuthwa, ndichitsulo.

Mu bukhuli, ndikufotokoza kusiyana pakati pa aogami ndi shirogami kukuthandizani kupanga zisankho mwanzeru pogula mipeni.

Zitsulo za ku Japan zapamwamba za carbon

Mipeni ya ku Japan ndi yodziwika bwino chifukwa chokhala ndi mpweya wambiri.

Pamene chitsulo chimakhala ndi mpweya wambiri, tsambalo limakhala lolimba komanso lakuthwa. Koma, chitsulocho chimakhala cholimba kwambiri chikakhala ndi mpweya wambiri.

Komanso, zitsulo zolimba ndizodziwika bwino chifukwa chakuthwa kwake - ndizomwe zimadulidwa bwino komanso zimadula nyama ndi ndiwo zamasamba.

Aogami ndi shirogami zitsulo ndi zitsulo za carbon zokwera kwambiri ku Japan koma zimakhalanso zovuta kwambiri kupanga chifukwa zitsulo za carbon izi ndizodziwika bwino kuti zimakhala zowonongeka.

Zotsatira zake, tsambalo limakonda kusweka ndi kuthyoka pomwe limapangidwa ndi amisiri.

Dziwani zambiri za luso la amisiri la ku Japan lopanga mipeni pano

Kodi aogami ndi chiyani?

Aogami ndi liwu la Chijapani lotanthauza chitsulo chabuluu kapena chitsulo cha pepala cha buluu ndipo dzinali limatanthawuza kukulunga pamapepala komwe wopanga amagwiritsa ntchito.

Anthu ambiri Kumadzulo amadziwa kuti aogami ndi chitsulo chabuluu ndipo ali ndi zonyansa zochepa monga phosphorous ndi sulfure.

Koma, kusiyana pakati pa aogami, poyerekeza ndi shirogami ndikuti chitsulo chabuluu chimakhalanso ndi tungsten (W) ndi Chromium (Cr).

Mankhwalawa amawonjezedwa chifukwa amatalikitsa nthawi yowumitsa kuti kutentha kusakhale kofunikira.

Komanso, W ndi Cr imapangitsa kuti tsambalo lisawonongeke komanso kung'ambika kwa tsiku ndi tsiku ndipo tsambalo limakhala lakuthwa kwambiri.

Mitundu ya zitsulo za buluu za aogami

Monga ndanenera, chitsulo chabuluu chimatha kugwira bwino kwambiri kuposa chitsulo choyera koma sichikhala chakuthwa. Sizitsulo zonse zabuluu zomwe zili zofanana.

Nawa magulu atatu a blue steel:

• Aogami #1 - ali ndi mpweya wa 1.2-1.4% ndi kuuma kwa 64-65. Chitsulochi sichachilendo ngati Aogami #2 koma chimadziwika chifukwa chosunga bwino m'mphepete chomwe chimakhala chakuthwa kwambiri. Chitsanzo chabwino cha mipeni ya aogami ndi yanagiba sushi mpeni ndi deba mpeni.
• Aogami #2 - ali ndi mpweya wa 1.0-1.2% ndi kuuma kwa 62-64. Ndiwolimba kwambiri komanso chitsulo cholimba - ndi cholimba kwambiri pamitundu 3 yachitsulo ya buluu ya aogami. Tsambali likhoza kunoledwa mosavuta. Chitsanzo chabwino cha chitsulo cha buluu cha aogami #2 ndi mpeni wa gyuto.
• Aogami Super - ali ndi 1.45% carbon content ndi kuuma kwa 65-67. Chitsulochi chawonjezeredwa Vanadium (V) kuti chikhale cholimba komanso champhamvu. Amadziwika ndi kukana kwambiri kuvala. Komanso, mtundu uwu wa buluu wa buluu uli ndi zosungirako zabwino kwambiri komanso zazitali kwambiri pazitsulo zitatu za aogami. Popanga tsamba, molybdenum wowonjezera ndi V amapereka nthawi yayitali kuti aumitse. Choncho, chitsulo ichi chikhoza kukhazikika mu mafuta, osati madzi okha. Mipeni ina ya santoku imapangidwa ndi chitsulo ichi.

Kodi shirogami ndi chiyani?

Shirogami amatchedwa white paper steel, kapena chitsulo chophweka choyera mu Chingerezi. Ndi mtundu wachitsulo cha ku Japan chomwe chimagwiritsidwa ntchito popanga mipeni yakukhitchini yomwe imakhala yakuthwa kwambiri.

M'mphepete ukhoza kunoledwa pogwiritsa ntchito Miyala yaku Japan (mtundu wa mwala wachilengedwe).

Chitsulo cha kaboni cha shirogami chili ndi tinthu tating'onoting'ono tambiri ta phosphorous (P) ndi sulfure (S).

Kupanga masamba a shirogami ndikovuta chifukwa kuli ndi kutentha kocheperako kuti aumitse.

Yakiire ndi njira yowumitsa m'mphepete ndipo kuzimitsa ndiko kuzizira kwachitsulo (kuchitidwa m'madzi) ndipo zonsezi ziyenera kuchitidwa mofulumira kuti zitsimikizire kuuma koyenera komwe kumapangitsa kuti tsambalo likhale lakuthwa.

Mitundu yazitsulo zoyera za shirogami

Pali mitundu itatu yazitsulo zoyera zomwe zili ndi carbon:

• Shirogami #1 - ali ndi 1.25-1.35% carbon content ndi kuuma kwa 61-64. Uwu ndi mtundu wovuta kwambiri wachitsulo choyera. Mpeni wopangidwa ndi shirogami 1 umakhala wakuthwa kwa nthawi yayitali koma ndi wofewa pang'ono ndipo ukhoza kusweka ngati umagwiritsidwa ntchito podula chichereŵechereŵe kapena fupa mwamphamvu. Mipeni ina yamtengo wapatali ya Santoku imapangidwa ndi chitsulo choyera #1.
• Shirogami #2 - ali ndi mpweya wa 1.05-1.15% ndi kuuma kwa 60-63 kotero ndizochepa pang'ono. Ndiwo mtundu wofala kwambiri wazitsulo zoyera zomwe zimagwiritsidwa ntchito popanga mpeni. Tsambali lidzakhala ndi kusungirako bwino kwambiri m'mphepete, ndilosavuta kulinola, ndipo silikhala lolimba ngati Shirogami 1. Chitsanzo cha chitsulo choyera cha shirogami #2 ndi mpeni wa nakiri waku Japan womwe umagwiritsidwa ntchito kudula masamba.
• Shirogami #3 - ali ndi mpweya wochepa wa 0.8-0.9%. Nthawi zambiri amatchedwa yellow
• chitsulo kotero mwaukadaulo si kwenikweni woyera pepala chitsulo. Koma, tsamba ili ndi lolimba kwambiri komanso lokhalitsa musayembekezere kuti likhala lalitali kwambiri chifukwa limatha kufooka mwachangu.

Kungoganizira pang'ono, Chithunzi cha VG-10 kapena AUS-10 zitsulo zili pafupifupi 1% carbon.

Kodi pali kusiyana kotani pakati pa zitsulo zoyera ndi zitsulo zabuluu?

Kusiyana kwakukulu pakati pa mitundu iwiriyi yazitsulo za carbon high-carbon ndi kuchuluka kwa carbon yomwe ili nayo ndi kuuma kwake.

Kusiyanitsa pakati pa awiriwa ndi kovuta kuzindikira ndi maso koma mukhoza kumva mosiyana mukamagwiritsa ntchito.

Lingaliro lalikulu ndilakuti masamba achitsulo oyera ndi akuthwa kuposa chitsulo chabuluu koma masamba achitsulo abuluu amakhala ndi m'mphepete mwabwinoko, kutanthauza kuti amakhala akuthwa kwanthawi yayitali mukadula khitchini ndi ntchito zokonzekera chakudya.

Chitsulo cha pepala la buluu ndi chomata kwambiri komanso chosamva ma abrasion. Izi ndichifukwa choti ili ndi chromium ndi tungsten, chifukwa chake imatha kudumpha pang'ono poyerekeza ndi chitsulo choyera.

Chitsulo choyera chimatulutsa okosijeni mwachangu kuposa chitsulo chabuluu koma chonsecho chimakhala ndi m'mphepete kwambiri. Chitsulo cha buluu ndi cholimba kwambiri kuposa chitsulo choyera komanso chosavuta kuchinola chifukwa chimasunga m'mphepete mwake kwa nthawi yayitali.

Panthawi yopangira ndi kupera mphamvu, zitsulo zoyera zimatulutsa zowala zambiri pamene zitsulo zabuluu zimapanga zochepa komanso zazing'ono. Choncho, mukhoza kusiyanitsa pakati pa awiriwa molingana ndi mphezi yawo.

Kodi chitsulo chabuluu kapena choyera ndichabwino?

Chitsulo cha buluu chimadziwika kuti chimakhala ndi m'mphepete mwabwino kwambiri kuposa chitsulo choyera. Komanso imalimbana ndi dzimbiri komanso dzimbiri. Komabe, chitsulo choyera chimakhala bwino pankhani yakuthwa. Chitsulo choyera sichikhala cholimba komanso chosavuta kuchinola.

Kodi mumadziwa kuti aogami (buluu chitsulo) ndi mtundu watsopano wachitsulo kuposa shirogami?

Koma, mukawafunsa ophika ambiri a sushi, amakonda mipeni yachitsulo ya shirogami chifukwa masamba ake ndi osalimba, akuthwa, komanso osavuta kugwiritsa ntchito makamaka ngati mukudula nsomba, veggies, ndi ma rolls a sushi.

Komabe, sindinganene kuti izi ndizochitika padziko lonse chifukwa pali ophika ambiri ndi ophika kunyumba omwe amasangalala ndi mpeni wa khitchini wa buluu chifukwa chitsulochi chimapereka ntchito yodabwitsa yodula komanso kusunga bwino.

Vuto ndilakuti chitsulo chabuluu chimakhala chophwanyika ndipo chimakonda kugunda. Chifukwa chake, muyenera kukhala aluso kwambiri kuti mugwiritse ntchito masamba awa moyenera. Anthu ambiri omwe amachita masewerawa amavutika ndi mipeni yachitsulo yochuluka ya carbon chifukwa cha mapangidwe ake abwino.

Mipeni ya ku Japan ndi zida za khichini zosalimba. Muyenera kutero nthawi zonse onetsetsani kuti mwawasunga moyenera komanso motetezeka.

Koma kunena zoona, mutha kugwiritsa ntchito mipeni yonse iwiri podula khitchini, kudula, ndi kuyika zosowa zapakhitchini. Zakudya zaku Japan.

Kaya mumasankha mpeni wakukhitchini wa aogami kapena shirogami, mukupanga chisankho chabwino.
