NKHANI

Kodi nyundo ya nyundo nthawi zambiri imapangidwa ndi zinthu ziti?

Ndi zinthu ziti zomwe zili mkati mwa nyundo? Zomwe zili mkati mwa nyundo yosweka ndi aloyi wochuluka wa chromium. High chromium alloy ndi chinthu chosamva kuvala chokhala ndi zinthu zabwino zotsutsana ndi kuvala, koma kulimba kwake kumakhala kotsika ndipo kusweka kwa brittle kumachitika. Pofuna kuwonetsetsa kuti nyundo yapamwamba ya chromium alloy ikugwira ntchito bwino, nyundo yofananira nthawi zambiri imatengedwa.

Imodzi ndikugwiritsa ntchito chogwirira cha nyundo cham'dera lalikulu kuthandizira nyundo ya chromium yapamwamba, ndipo kulimba kwa chogwirira cha nyundo kumathandizira mphamvu yayikulu pakuphwanya.

Chachiwiri ndi chophatikizika chamadzimadzi chawiri. Izi zimagwiritsa ntchito mitundu yosiyanasiyana yosakanikirana ya chromium, molybdenum, mkuwa, faifi tambala, vanadium, titaniyamu ndi ma aloyi ena komanso njira yolimbikitsira komanso yapadera yopanga. Imaphatikiza kuponyedwa kwa aloyi wapamwamba kwambiri wa chromium ndi kukana kwamphamvu kwambiri komanso kukana kutentha kwa okosijeni. , Kulimbana ndi kutopa kwamafuta (kapena kukana kwa dzimbiri) kumaphatikizidwa ndi kulimba kwabwino komanso kusinthika kwachitsulo choponyedwa, ndipo kumakhala ndi kukana kwamphamvu kwambiri komanso kukana kukhudzidwa konse komwe kumakhala kovuta kukwaniritsa ndi chinthu chimodzi chachitsulo.

Nyundo yolimba ya chromium yosamva kuvala ndi chinthu chopangira nyundo wamba yomwe imadzaza ndi zinthu zolemetsa zachitsulo cha chromium. Mbewuzo zimayengedwa pambuyo pa kusinthidwa panthawi ya smelting ndi kuponyedwa ndikupangidwa mu sitepe imodzi pansi pa zovuta zoipa. Nyundoyo imapangidwa ndi chitsulo chapamwamba cha chromium, chomwe chimakhala ndi kachulukidwe kakang'ono, chimatha kupirira katundu wambiri, komanso chimakhala ndi zinthu zokwanira zotsutsana ndi kuvala. Chogwirira cha nyundo chimapangidwa ndi chitsulo chochepa cha alloy cholimba bwino ndipo sichidzathyoka kuti chitsimikizire kuti chikugwira ntchito bwino.

Nyundo yokhala ndi chromium yosamva kuvala imagwiritsidwa ntchito makamaka kuphwanya miyala ina ndi kuuma kwakukulu, monga basalt, granite, miyala ya mitsinje, ndi zina zotero. zatukuka kwambiri, komanso zida zophwanyira zachitanso chitukuko mwachangu komanso momveka bwino, ndipo kugwiritsa ntchito nyundo, chowonjezera chachikulu cha chopondapo, chawonjezeka.

Zhejiang Jinhua Shanvim Viwanda ndi Trade Co., Ltd., yomwe idakhazikitsidwa mu 1991. Zogulitsa zazikuluzikulu ndizovala zosagwira ntchito monga malaya, mbale ya mbale, mbale ya nsagwada, nyundo, nkhonya, mphero yamagetsi, ndi zina zotero. Sing'anga ndi mkulu chromium kuponyedwa chitsulo zipangizo, etc.. Iwo makamaka umabala ndi kupereka kuvala zosagwira castings kwa migodi, simenti, zomangira, zomangamanga zomangamanga, mphamvu ya magetsi, mchenga ndi miyala aggregates, makina kupanga ndi mafakitale ena.
