Zitsulo Zapamwamba (HSS)

(Chitsulo chothamanga kwambiri (HSS)), chimagwiritsidwa ntchito makamaka ngati zida zodulira (zodula zida) ndipo ndi chitsulo chachitsulo chazitsulo.HSS imagwiritsidwanso ntchito pazida zopangira chifukwa ndi yabwino kwambiri pogaya (zomwe zimalolanso kubwezeretsanso zida zosamveka, mwachitsanzo).

Poyerekeza ndi zitsulo zozizira zogwirira ntchito, kudula maulendo atatu mpaka kanayi apamwamba ndipo motero kutentha kwakukulu kwa ntchito kumatha kutheka.Izi zimachitika chifukwa cha kutentha komwe chitsulo chimamangidwira pa 1,200 ° C kenako kuziziritsidwa.

HSS imapeza kuuma kwake kuchokera ku kapangidwe kake kamene kali ndi chitsulo ndi carbon.Kuphatikiza apo, zowonjezera zowonjezera zowonjezera zoposa 5% zili, zomwe zimapangitsa HSS kukhala chitsulo chapamwamba kwambiri.

Ubwino wa HSS ambiri

· Kutentha kwa ntchito kupitirira 600°C

·Kuthamanga kwambiri

· Mphamvu yayikulu (mphamvu yosweka kwambiri)

·Kugaya bwino panthawi yopanga

· Kusungidwa bwino kwa zida zosamveka

· Mtengo wotsika kwambiri

Kuchuluka kwa cobalt, kumapangitsanso chitsulo cholimba.Zomwe zili mu cobalt zimawonjezera kuuma kotentha ndipo mutha kudula bwino zida zomwe ndizovuta kuzidula.M35 ili, 4.8 - 5% cobalt ndi M42, 7.8 - 8 % cobalt.Ndi kuuma kowonjezereka, komabe, kulimba kumachepa.

Mapulogalamu

Chitsulo chothamanga kwambiri, chokhala ndi madigiri osiyanasiyana a kuuma ndi zokutira, ndizoyenera ntchito zosiyanasiyana.

Ndi chitsulo chothamanga chiti chomwe mukufuna pa ntchito yanu chimadalira momwe mukudulira, kaya mukubowola, ulusi kapena countersinking.

Mapeto ndi chidule

Zobowola zimapangidwa ndi alloyed high speed steel (HSS).Ndi chida ichi chitsulo, ntchito kutentha kwa 600 °C akhoza anafika, amene akhoza kuchitika pamene kudula mwachitsanzo zitsulo kapena zitsulo.

Pamene kuuma kwa zinthu kumawonjezeka, mungagwiritse ntchito chitsulo chothamanga kwambiri chokhala ndi cobalt yapamwamba (5% kapena kuposa).Momwe cobalt ikuyenera kukhalira zimatengera momwe mumagwiritsira ntchito.Mwachitsanzo, ngati mukufuna kubowola chitsulo chosapanga dzimbiri, nthawi zambiri mumagwiritsa ntchito chobowola chosatsekedwa cha M35.Nthawi zina zida zachitsulo za HSS zokhala ndi zokutira za TiAlN ndizokwanira.

Tsopano mutha kusankha chitsulo choyenera pakugwiritsa ntchito kwanu.
