Gịnị bụ nso nke usoro arụmọrụ n'ịme tungsten ígwè ebu?

①Na-arọ nrọ. GCr15 ígwè nwere mma forging arụmọrụ na forging okpomọkụ nso nketungsten ígwè ebuobosara. The forging usoro ụkpụrụ bụ n'ozuzu: kpo oku 1050 ~ 1100 ℃, mbụ forging okpomọkụ 1020 ~ 1080 ℃, ikpeazụ forging okpomọkụ 850 ℃, na ikuku jụrụ mgbe forging. Ihe owuwu a kpụrụ akpụ kwesịrị ịbụ ezigbo ahụ spheroidal flake. Ụdị dị otú ahụ nwere ike spheroidized na annealed na-enweghị normalize.

②Hazie ọkụ. The normalizing kpo oku okpomọkụ nke GCr15 ígwè bụ n'ozuzu 900 ~ 920 ℃, na obi jụrụ ọnụego apụghị ịbụ ihe na-erughị 40 ~ 50 ℃ / min. Enwere ike ime ka obere ihe na-akpụ akpụ dị jụụ n'ikuku; Enwere ike ime ka ntọala buru ibu dị jụụ site na mgbawa ikuku ma ọ bụ ịgba; Enwere ike ime ka nnukwu ihe na-akpụ akpụ nke nwere dayameta karịa 200mm dị mma na mmanụ ọkụ, ma wepụ ya maka ikuku jụrụ oyi mgbe elu okpomọkụ dị ihe dịka 200 ° C. Nchegbu dị n'ime ahụ nke usoro nju oyi nke ikpeazụ nke tungsten steel kpụrụ dị oke ma dị mfe ịgbawa. Ekwesịrị ịgbatị ya ozugbo ma ọ bụ tinye usoro mgbakasị ahụ.

③Spheroidizing annealing. The spheroidizing annealing usoro nkọwa maka GCr15 ígwè bụ n'ozuzu: tungsten ígwè ebu kpo oku okpomọkụ 770 ~ 790 ℃, ejide okpomọkụ 2 ~ 4h, isothermal okpomọkụ 690 ~ 720 ℃, isothermal oge 4 ~ 6h. Mgbe annealing, ihe owuwu ahụ dị mma na edo edo pearlite nwere ike nke 217 ~ 255HBS na ezigbo ịkpụ ọrụ. GCr15 ígwè nwere ezigbo hardening (oke ike siri ike maka mmanụ quenching bụ 25mm), na omimi nke oyi akwa siri ike enwetara n'okpuru mmanụ quenching yiri nke carbon ngwá ọrụ ígwè site na mmiri quenching.
