iindaba

Igama eliqhelekileyo lezinto zentsimbi ezinokumelana okuqinileyo, intsimbi enganyangekiyo yolona hlobo lusetyenziswa kakhulu kwizinto ezinxitywayo namhlanje.

Ukuhlelwa

Zininzi iindidi zentsimbi engagugiyo, enokuthi yahlulwe ngokoqikelelwa ukuba ibe yintsimbi ephezulu yemanganese, intsimbi ephakathi kunye nesezantsi, ichrome-molybdenum-silicon-manganese intsimbi, intsimbi enganyangekiyo kwicavitation, intsimbi engagugiyo kunye nokunxiba okukhethekileyo. -intsimbi enganyangekiyo.Ezinye iintsimbi eziqhelekileyo ze-alloy ezifana nensimbi engenasici, intsimbi yokuthwala, insimbi yensimbi ye-alloy kunye ne-alloy structural steel nazo zisetyenziswa njengentsimbi engagungqiyo phantsi kweemeko ezithile.Ngenxa yomthombo wabo ofanelekileyo kunye nokusebenza okugqwesileyo, zikwasetyenziselwa ukusetyenziswa kwentsimbi engagungqiyo.ipesenti ethile.

ukwakheka kweekhemikhali

Iintsimbi eziphakathi nezisezantsi ezikwazi ukumelana ne-alloy zihlala zinemichiza efana nesilicon, manganese, chromium, molybdenum, vanadium, tungsten, nickel, titanium, boron, copper, umhlaba onqabileyo, njl njl. eUnited States zenziwe nge-chrome-molybdenum-silicon-manganese okanye i-chrome-molybdenum steel.Uninzi lweebhola zokugaya e-United States zenziwe nge-medium and high carbon chrome molybdenum steel.Kwizixhobo zokusebenza ezisebenza phantsi kweemeko zokunxitywa kwe-abrasive kumaqondo obushushu aphezulu (afana ne-200 ukuya ku-500 ° C) okanye iindawo zokusebenza eziphantsi kobushushu obuphezulu ngenxa yobushushu obukhukhulayo, iialloyi ezifana nechrome-molybdenum-vanadium, chrome-molybdenum-vanadium-nickel okanye i-chrome-molybdenum-vanadium-tungsten alloys ingasetyenziswa.Ukugaya insimbi, emva kokuba olu hlobo lwentsimbi lucinywe kwaye lufakwe kwiqondo lokushisa eliphakathi okanye eliphakamileyo, kukho umphumo wesibini wokuqina.

isicelo

Insimbi engaguqukiyo isetyenziswa kakhulu koomatshini bemigodi, imigodi yamalahle kunye nokuthutha, oomatshini bokwakha, oomatshini bezolimo, izinto zokwakha, oomatshini bombane, ezothutho zikaloliwe kunye namanye amasebe.Umzekelo, iibhola zentsimbi, iipleyiti zentsimbi, amazinyo eebhakethi kunye neebhakethi ze-excavators, iindonga eziqengqelekayo zodaka, iipleyiti zamazinyo kunye neentloko zesando zee-crushers ezahlukeneyo, izihlangu zomkhondo weetrektara kunye neetanki, iipleyiti zokubetha ii-fan mills, iifolokhwe zikaloliwe, iifolokhwe eziphakathi. i-groove-in-plates, i-grooves, i-circular chain for scraper conveyors kwimigodi yamalahle, ii-blades kunye namazinyo e-bulldozers, ii-linings zamabhakethi eelori ezinkulu zombane, i-roller cone bits ye-oyile yokugqobhoza kunye nentsimbi ekrwada evulekileyo, njl njl. kukhawulelwe ekusetyenzisweni kwentsimbi enganyangekiyo ephantsi kokunxitywa kwe-abrasive, kwaye zonke iintlobo zezinto zokusebenza ezinentshukumo ehambelanayo koomatshini abahlukeneyo ziya kuvelisa iintlobo ezahlukeneyo zokunxiba, eziya kuphucula ukuxhathisa kwezixhobo zokusebenza.Iimfuno zokusila okanye ukusetyenziswa kwentsimbi engagungqiyo, imizekelo mininzi.Imithombo yeendaba yokusila (iibhola, iirodi kunye neeliner) ezisetyenziswa kwintsimbi ekrwada kunye nesamente ziindawo zokunxiba zentsimbi ezisetyenziswa kakhulu.EUnited States, iibhola zokusila zenziwe ngokubanzi okanye zifakwe nge-carbon kunye ne-alloy steels, ezenza i-97% yokusetyenziswa kwebhola yokugaya.ECanada, iibhola zetsimbi zibalelwa kwi-81% yeebhola zokugaya ezisetyenzisiweyo.Ngokwezibalo ngasekupheleni kweminyaka yee-1980, ukusetyenziswa kwe-China yeebhola zokusila ngonyaka malunga ne-800,000 ukuya kwi-1 yezigidi zeetoni, kwaye ukusetyenziswa konyaka kwe-linings ye-mill linings kwilizwe lonke phantse i-200,000 yeetoni, ezininzi zazo ziyimveliso yentsimbi.Umkhombe ophakathi we-scraper conveyor kumgodi wamalahle waseChina udla i-60,000 ukuya kwi-80,000 yeetoni zeepleyiti zentsimbi minyaka le.
