Bwerani mudzadziwe za HSS
Chitsulo chothamanga kwambiri (HCS) ndi chida chovuta kwambiri, kuvala kwambiri kukana ndi kukana kwamphamvu, kumadziwikanso ngati chitsulo champhamvu, chimakhala chovuta ngakhale utakhazikika. Amatchedwanso chitsulo choyera.
Chitsulo chothamanga kwambiri ndi chitsulo chovuta chokhala ndi zovuta zomwe zimakhala ndi zinthu zopanga zabisi monga ma tungsten, molybdenum, chromium, vadium ndi cobada. Zokwanira zonse zoyatsira zidafika pafupifupi 10 mpaka 25%. Imatha kukhalabe kuuma kwambiri pansi pa kutentha kwambiri (pafupifupi 500 ℃) Kudula kwamphamvu kwambiri, HRC ikhoza kukhala pamwamba pa 60. Ichi ndiye chikhalidwe chofunikira kwambiri cha HSS - kuvuta kofiira. Ndipo chida cha Carbon chimakhala chitsulo chokhazikika komanso kutentha kwa kutentha, kutentha kwanyengo, ngakhale pamakhala kuvuta kwambiri, koma kutentha kudzakweranso, komwe kumalepheretsa kudula chitsulo. Ndi chitsulo chothamanga kwambiri chifukwa cha kuuma kwabwino kwambiri, kupanga zophophonya za kaboni pazidzi.
Chitsulo chothamanga kwambiri chimagwiritsidwa ntchito popanga zida zotsekemera komanso zosokoneza bongo komanso zochulukirapo komanso zowonjezera zowonjezera zimafa, zomwe zimakulitsa zida, makina, makina amawona kufa.
Bwerani mudzadziwe za zitsulo za tungsten
Chitsulo cha Tungsten (Carbide) chimakhala ndi mndandanda wazinthu zabwino kwambiri monga kuvuta kwambiri, kuvala mphamvu bwino, kukana kumenyedwa kotheratu mpaka pa 5000 ℃ ℃.
Chitsulo cha tungsten, chomwe zinthu zake zikuluzikulu ndi zigawo zazikuluzikulu ndi cobalt, maakaunti a 99% ya zinthu zonse ziwiri ndi zitsulo zina, zimadziwikanso kuti Cangding, ndipo amadziwika kuti ndi mano a mafakitale amakono.
Chitsulo cha tungsten chimakhala ndi zinthu zomveka zomwe zili ndi kapangidwe kake ka mankhwala carbidisi imodzi. Cangsten Carbide, Cobat Carbide, Niobium Carbide, calbium Carbide, ndipo tantolum carbide ndi zinthu zofala za chitsulo. Kukula kwa njere ya carbide (kapena gawo) nthawi zambiri pamitundu 0,2-10, ndipo mbewu ya carbide imalumikizidwa pogwiritsa ntchito chopondera chitsulo. Zitsulo zomangira nthawi zambiri zimakhala zitsulo zopangira zitsulo, zomwe nthawi zambiri zimakonda ndi nickel. Chifukwa chake kuli mitengo ya zipatso, tubsten-nickel emoys ndi tuwsten-tibabala-cobalt.
Kupanga uchimo wochimwa ndikukanikiza ufa mu billet, kenako kukhala ndi ng'anjo yochimwa kuti itenthe mpaka kutentha kwapadera (kusunga nthawi), kenako ndikukonzanso zinthu zofunika.
①Tungsten ndi cobabala
Gawo lalikulu ndi cangsten carbide (WC) ndi Cobar Cobalt (CO). Kalasiyo imapangidwa ndi "yg" ("zolimba, cobat" ku Hanya Pinyin) ndi kuchuluka kwa mitengo ya cobabala. Mwachitsanzo, yg8, zomwe zikutanthauza kuti pafupifupi Wco = 8% ndipo kupumula ndi carbide carbide.
②Tungsten, Titanium ndi Cobatt Center Carbide
Zigawo zikuluzikulu ndi cangsten Carbide, catbium carbide (tic) ndi cobatt. Kalasiyo imapangidwa ndi "YT" ("yolimba, titanium" ku Hanya Pinyin) ndi kuchuluka kwa carbide. Mwachitsanzo, yt15, zikutanthauza kuti gawo lalikulu = 15%, ena onse ndi cangsten ndi cobalt zomwe zili mu tumpsten titalt calbide calbide.
③Tungsten-Titanium-tantalum (Niobium) Carbide
Zigawo zikuluzikulu ndi cangsten Carbide, Titanium Carbide, tantalum carbide (kapena Niobium Calbide) ndi cobat. Carbide yamtunduwu imatchedwanso cholinga cha carbide kapena carbide wapadziko lonse lapansi. Gawoli lili ndi "yw" ("zolimba" ndi "miliri" ku Hanya Pinyin) kuphatikiza manambala otsatizana, monga yw1.
Chitsulo cha tungsten chimakhala ndi mndandanda wazinthu zabwino kwambiri monga kuvuta kwambiri, kuvala mphamvu bwino komanso kukana kwake, etc. Kulimbana kwambiri kukhazikitsidwa kwa 5000 ℃. Carbide yolumikizidwa kwambiri imagwiritsidwa ntchito ngati zida, monga zida zosiyirira, zida zothetsa, zida, zida zotopetsa, etc. Kuthamanga kwa ma carbide yatsopano.
