Chifukwa chiyani 304 zitsulo zosapanga dzimbiri ziyenera kugwiritsidwa ntchito kukhitchini?

Kugwiritsa ntchito kwambiri zitsulo zosapanga dzimbiri ndikusintha kukhitchini.Ndi zokongola, zolimba, komanso zosavuta kuyeretsa.Iwo mwachindunji kusintha mtundu ndi kukhudza kwa khitchini.Chifukwa chake, malo owoneka bwino akhitchini asinthidwa kwambiri.
Komabe, pali mitundu yambiri yazitsulo zosapanga dzimbiri, ndipo kusiyana kwake sikochepa.Nthawi zina mafunso okhudzana ndi chitetezo amatha kumveka, ndipo zimakhala zovuta kuwasankha.

Makamaka pankhani ya miphika, tableware ndi ziwiya zina zomwe zimanyamula chakudya mwachindunji, zinthuzo zimakhala zovuta kwambiri.Kodi kusiyanitsa iwo?Sanjiangfood (ID: sanjiangfood) amakhulupirira kuti aliyense ayenera kugwiritsa ntchito zonse zomwe zili kukhitchini momveka bwino.
Kodi chitsulo chosapanga dzimbiri ndi chiyani?
Mbali yapadera ya chitsulo chosapanga dzimbiri imatsimikiziridwa ndi zinthu ziwiri, zomwe ndi chromium ndi faifi tambala.Popanda chromium, palibe chitsulo chosapanga dzimbiri, ndipo kuchuluka kwa nickel kumatsimikizira mtengo wa chitsulo chosapanga dzimbiri.

Chitsulo chosapanga dzimbiri chimatha kukhala ndi kuwala kwake mumlengalenga ndipo sichichita dzimbiri chifukwa chimakhala ndi zinthu zina za chromium alloy (osachepera 10.5%), zomwe zimatha kupanga filimu yolimba ya okusayidi pamwamba pazitsulo zomwe sizisungunuka muzofalitsa zina. .

Nickel ikawonjezeredwa, magwiridwe antchito a chitsulo chosapanga dzimbiri amawongoleranso.Ili ndi kukhazikika bwino kwamankhwala mumpweya, m'madzi, ndi nthunzi, ndipo imakhala ndi kukhazikika kokwanira mumitundu yambiri ya asidi, alkali, ndi mchere wamadzimadzi, ngakhale pa kutentha kwambiri kapena m'malo otsika kutentha, imathabe kukhalabe ndi ubwino wa dzimbiri. kukaniza.

Malingana ndi microstructure, zitsulo zosapanga dzimbiri zimagawidwa mu martensitic, austenitic, ferritic ndi duplex zitsulo zosapanga dzimbiri.Austenite ali ndi pulasitiki wabwino, mphamvu zochepa, kulimba kwina, kukonza kosavuta ndi kupanga, ndipo alibe ferromagnetism.

Chitsulo chosapanga dzimbiri cha Austenitic chinatuluka ku Germany mu 1913 ndipo chakhala chikugwira ntchito yofunika kwambiri pazitsulo zosapanga dzimbiri.Kupanga ndi kugwiritsiridwa ntchito kwake kumapanga pafupifupi 70% ya kuchuluka kwa kupanga ndi kugwiritsa ntchito zitsulo zosapanga dzimbiri.Palinso magiredi achitsulo kwambiri, kotero kuti zitsulo zambiri zosapanga dzimbiri zomwe mumaziwona tsiku lililonse ndi zitsulo zosapanga dzimbiri za austenitic.

Chitsulo chodziwika bwino cha 304 ndi chitsulo chosapanga dzimbiri cha austenitic.Muyezo wakale wa dziko la China unali 0Cr19Ni9 (0Cr18Ni9), kutanthauza kuti uli ndi 19% Cr (chromium) ndi 9% Ni (nickel).0 imatanthawuza kukhala ndi carbon<= 0.07%.

Ubwino wa chikhalidwe cha dziko la China ndikuti zinthu zomwe zili muzitsulo zosapanga dzimbiri zimamveka bwino pang'onopang'ono.Ponena za 304, 301, 202 ndi zina zotero, ndilo dzina la United States ndi Japan, koma tsopano aliyense akuzoloŵera dzinali.
