Mawu akuti zida zachitsulo zokhala ndi zolimba zolimba, zitsulo zosagwira ntchito ndizomwe zimagwiritsidwa ntchito kwambiri masiku ano.

Gulu

Pali mitundu yambiri yachitsulo chosamva kuvala, chomwe chingathe kugawidwa kukhala chitsulo chachikulu cha manganese, chitsulo chapakati ndi chochepa cha alloy kuvala, chrome-molybdenum-silicon-manganese steel, cavitation-resistant steel, chitsulo chosamva kuvala ndi kuvala kwapadera. - chosagwira chitsulo.Zitsulo zina wamba monga zitsulo zosapanga dzimbiri, zitsulo zokhala ndi chitsulo, chitsulo cha aloyi ndi zitsulo zomangika zimagwiritsidwanso ntchito ngati chitsulo chosagwira ntchito pamikhalidwe inayake.Chifukwa cha gwero lawo losavuta komanso ntchito yabwino kwambiri, amagwiritsidwanso ntchito pogwiritsira ntchito zitsulo zosavala.peresenti inayake.

mankhwala opangidwa

Zitsulo zapakatikati ndi zochepa za aloyi zosamva kuvala nthawi zambiri zimakhala ndi zinthu monga silikoni, manganese, chromium, molybdenum, vanadium, tungsten, faifi tambala, titaniyamu, boron, mkuwa, nthaka yosowa, ndi zina zambiri. ku United States amapangidwa ndi chrome-molybdenum-silicon-manganese kapena chrome-molybdenum chitsulo.Mipira yambiri yopera ku United States imapangidwa ndi chitsulo chapakati komanso chapamwamba cha carbon chrome molybdenum.Kwa zida zogwirira ntchito zomwe zimagwira ntchito pansi pa ma abrasive amavala pa kutentha kwambiri (monga 200 mpaka 500 ° C) kapena zogwirira ntchito zomwe malo ake amatenthedwa chifukwa cha kutentha kwamphamvu, ma alloys monga chrome-molybdenum-vanadium, chrome-molybdenum-vanadium-nickel kapena chrome-molybdenum-vanadium-tungsten alloys angagwiritsidwe ntchito.Chitsulo chopera, pambuyo pa zitsulo zamtundu uwu kuzimitsidwa ndi kutenthedwa pa sing'anga kapena kutentha kwakukulu, palinso kuuma kwachiwiri.

ntchito

Chitsulo chosamva kuvala chimagwiritsidwa ntchito kwambiri pamakina amigodi, migodi ya malasha ndi zoyendera, makina omanga, makina aulimi, zida zomangira, makina amagetsi, zoyendera njanji ndi madipatimenti ena.Mwachitsanzo, mipira yachitsulo, mbale zomangira za mphero za mpira, mano a ndowa ndi ndowa za zofukula, makoma amatope, mbale za mano ndi mitu ya nyundo yamitundu yosiyanasiyana, nsapato za mathirakitala ndi akasinja, mbale zowombera mphero, njanji mafoloko, pakati. ma groove-in-plates, grooves, maunyolo ozungulira a zomangira m'migodi ya malasha, masamba ndi mano a bulldozers, zomangira za ndowa zazikulu zamagalimoto zamagalimoto amagetsi, zodzigudubuza zamafuta opaka mafuta ndi chitsulo chotseguka, ndi zina zambiri. zochepa pakugwiritsa ntchito zitsulo zosagwira ntchito zomwe zimavalidwa ndi abrasive, ndipo mitundu yonse ya zida zogwirira ntchito zoyenda pang'onopang'ono pamakina osiyanasiyana zidzatulutsa mitundu yosiyanasiyana ya kuvala, zomwe zimathandizira kukana kwa zida zogwirira ntchito.Zofunikira zogaya kapena kugwiritsa ntchito zitsulo zosagwira ntchito, zitsanzo ndi zambiri.Zida zogayira (mipira, ndodo ndi zomangira) zomwe zimagwiritsidwa ntchito muzitsulo za ore ndi simenti ndizovala zazitsulo zogwiritsidwa ntchito kwambiri.Ku United States, mipira yopera nthawi zambiri imapangidwa kapena kuponyedwa ndi zitsulo za carbon ndi alloy, zomwe zimapanga 97% yazomwe zimagwiritsidwa ntchito pogaya mpira.Ku Canada, mipira yachitsulo imapanga 81% ya mipira yopera yomwe imagwiritsidwa ntchito.Malinga ndi ziwerengero chakumapeto kwa zaka za m'ma 1980, China kudya pachaka akupera matani pafupifupi 800,000 kwa 1 miliyoni matani, ndi kumwa pachaka linings mphero dziko pafupifupi 200,000 matani, ambiri mwa zinthu zitsulo.Malo apakati a scraper conveyor mu mgodi wa malasha ku China amadya matani 60,000 mpaka 80,000 a zitsulo chaka chilichonse.
