Malinga ndi zomwe mafakitale amapanga, msika wapadziko lonse wa yothamanga zitsulo (HSS) zida zodulira zikuyembekezeka kukula mpaka $ 10 biliyoni pofika chaka cha 2020. Jackie Wang-General Manager wa Shanghai Histar Metal, akuwona chifukwa chomwe HSS idakhalabe njira yotchuka, nyimbo zosiyanasiyana zomwe zidalipo komanso momwe zinthuzo zasinthira makampani osintha mwachangu.

Ngakhale mpikisano womwe ukukula kuchokera ku carbide wolimba, HSS ikupitilizabe kutchuka ndi opanga chifukwa chazida zake zolimba komanso kuwuma kwakukulu komanso kulimba. Zida zodulira HSS ndizoyenera kwambiri pakupanga zinthu zambiri komwe zida zamoyo, kusinthasintha, zokolola komanso mtengo wazida ndizofunikira kwambiri kwa ogwiritsa ntchito kumapeto. Izi zimagwirabe gawo lalikulu pakupanga makina odalirika komanso odalirika pazinthu zambiri.

Komanso, zomwe zikuyang'ana pakadali pano pazabwino pazogulitsa, zomwe zikukwaniritsa zofunikira pakasitomala pamtengo wotsika mtengo, zikuwoneka zokongola munyengo yazachuma yapadziko lonse lapansi.

Kuthandizira kuchuluka kwakukula padziko lonse lapansi kwa HSS, opanga zida zopangira apereka zida zochulukirapo ku gawo ili. Izi zikuphatikiza kuwonjezeka kwa ndalama osati kungopanga zatsopano komanso ntchito zofufuza ndi chitukuko, zomwe zapangitsa kuti zida za HSS zikhale zodalirika ndikuchepetsa zolakwika, kutsitsa mitengo yopanga komanso nthawi yayifupi yotsogola. Kuphatikizidwa kwa magawo apamwamba, kuphatikiza ufa wamafuta ndi zokutira zathandiza kwambiri pakukweza magwiridwe antchito.

Shanghai Histar Metal imapereka pepala lothamanga kwambiri, bala yozungulira komanso bar. Zipangizozi zimagwiritsidwa ntchito pobowola, makina ozimitsira, ogwiritsanso ntchito, matepi komanso odulira mphero.

Kulemba kwa HSS

Zolemba za HSS zimakhala ndi chromium (4%), tungsten (pafupifupi 6%), molybdenum (mpaka 10%), vanadium (pafupifupi 2%), cobalt (mpaka 9%) ndi kaboni (1%). Mitundu yosiyanasiyana yamakalasi imadalira magawo osiyanasiyana azinthu zowonjezera.

Chromium imathandizira kulimba kolimba ndikupewa kukula. Tungsten imapereka kudula kocheperako komanso kukana kutentha, komanso kuuma bwino komanso kutentha kwambiri. Molybdenum - chopangidwa ndi mkuwa ndi tungsten - imathandizanso kudula bwino komanso kuuma, komanso kukana kutentha. Vanadium, yomwe imapezeka mumchere wambiri, imapanga ma carbides olimba kwambiri pakukana kwamphamvu, kumawonjezera kutentha ndi mphamvu, komanso kusunganso kuwuma.

Cobalt imathandizira kukana kutentha, kusungika kwa kulimba ndikusinthasintha pang'ono kutentha, pomwe kaboni, kumawonjezera kukanika ndipo imayambitsa zovuta (pafupifupi 62-65 Rc). Kuphatikiza kwa 5-8% more cobalt ku HSS kumalimbitsa mphamvu komanso kuvala kukana. Nthawi zambiri, mabowola opangidwa ndi kuwonjezera kwa cobalt ambiri amagwiritsidwa ntchito muntchito zina.

Ubwino

Zida za HSS zimatha kulimbana ndi kugwedezeka, kaya makina amtundu wanji, ngakhale kukhazikika kwataika pakapita nthawi komanso mosasamala kanthu kogwirira ntchito. Ikhoza kuteteza magwiridwe antchito pamankhwala opangira mavitamini ndikuthana ndimakondedwe amitundu yosiyanasiyana omwe angapangitse kusintha kwamafuta.

Komanso, chifukwa cha mphamvu ya HSS, opanga zida amatha kupanga mdera lakuthwa kwambiri. Izi zimapangitsa kuti makina azikhala ovuta kugwiritsa ntchito, amapereka ntchito yocheperako yolimba yazitsulo zosapanga dzimbiri zosungunulira ndi ma nickel, ndipo zimapereka mawonekedwe abwinoko komanso kulolerana kwa zida zamagetsi.

Chitsulo chimadulidwa osang'ambika, chimakhala ndi chida chotalikirapo chotsika pang'ono. Ikufunikanso mphamvu zochepetsera, zomwe pamapeto pake zimatanthauza kugwiritsa ntchito mphamvu zochepa pazida zamakina. Kuchokera pamawonekedwe azida, HSS imagwira bwino ntchito ndikudula kwapakatikati.

Chidule

M'nthawi yomwe ogwiritsa ntchito amafunikira zida zodalirika, zosasinthasintha, zogwiritsira ntchito pamtengo wotsika mtengo, zitsulo zothamanga kwambiri akadali chisankho choyenera pazinthu zambiri. Mwakutero, imatha kukhala yokha pamsika motsutsana ndi zida zazing'ono komanso zapamwamba kwambiri.

Ngati pali chilichonse, HSS Kwa zaka zambiri wakhala wolimba podzikongoletsa ndi zokutira zatsopano, kusintha kapangidwe kake ndikuwonjezera ukadaulo watsopano, zonse zikuthandizira kuti zisunge ngati chinthu chofunikira pamsika wazitsulo.

Makampani azida zodulira nthawi zonse amakhala opikisana ndipo HSS imakhalabe gawo lofunikira pakupatsa makasitomala zomwe zakhala zofunikira nthawi zonse: kusankha bwino.
