A na-ahụkarị ihe mgbakwunye FeCrAl n'ọhịa ọkụ eletrik.

Maka na o nwere ọtụtụ uru, n'ezie o nwekwara ọghọm, ka anyị mụọ ya.

Uru:

1, Okpomọkụ ojiji n'ikuku dị elu.

Okpomọkụ kachasị elu nke HRE alloy na iron-chromium-aluminum electrothermal alloy nwere ike iru 1400℃, ebe nke Cr20Ni80 alloy na nickel-chromium electrothermal alloy nwere ike iru 1200℃.

2, Ndụ ọrụ ogologo oge

N'okpuru otu okpomọkụ ọrụ dị elu n'ikuku ahụ, ndụ nke ihe Fe-Cr-Al nwere ike ịdị ogologo oge karịa nke ihe Ni-Cr ugboro 2-4.

3, Ibu elu dị elu

Ebe ọ bụ na ihe mgbakwunye Fe-Cr-Al na-enye ohere maka okpomọkụ dị elu na ndụ ogologo oge ọrụ, ibu elu nke ihe mejupụtara nwere ike ịdị elu, nke na-eme ka okpomọkụ dịkwuo elu ngwa ngwa, kamakwa ọ na-azọpụta ihe ndị mejupụtara ihe.

4, Ezigbo iguzogide oxidation

Nhazi ihe nkiri oxide Al2O3 nke e guzobere n'elu ihe alloy Fe-Cr-Al dị obere, ọ na-arapara nke ọma na ihe mejupụtara ya, ọ dịghịkwa mfe ibute mmetọ n'ihi mgbasa. Na mgbakwunye, Al2O3 nwere nnukwu iguzogide na ebe ịgbaze agbaze, nke na-ekpebi na ihe nkiri oxide Al2O3 nwere ezigbo iguzogide oxidation. Nguzogide carburizing dịkwa mma karịa Cr2O3 nke e mepụtara n'elu ihe alloy Ni-Cr.

5, Obere ike ndọda kpọmkwem

Ike ndọda nke ihe mejupụtara Fe-Cr-Al pere mpe karịa nke ihe mejupụtara Ni-Cr, nke pụtara na ọ bara uru karịa iji ihe mejupụtara Fe-Cr-Al karịa ihe mejupụtara Ni-Cr mgbe a na-eme otu ihe ahụ.

6, Nnukwu iguzogide

Nguzogide nke ihe mgbakwunye Fe-Cr-Al dị elu karịa nke ihe mgbakwunye Ni-Cr, yabụ enwere ike ịhọrọ ihe mgbakwunye buru ibu mgbe a na-emepụta ihe, nke bara uru iji mee ka ihe mejupụtara dị ogologo ndụ ọrụ, karịsịa maka waya alloy dị mma. Mgbe ahọpụtara ihe ndị nwere otu nkọwapụta ahụ, ka nguzogide ahụ na-arị elu, ka ihe ahụ ga-echekwakwu, ebe ọnọdụ nke ihe mejupụtara ya dị obere ga-adị. Na mgbakwunye, nguzogide nke ihe mgbakwunye Fe-Cr-Al anaghị emetụta ọrụ oyi na ọgwụgwọ okpomọkụ karịa nke ihe mgbakwunye Ni-Cr.

7, Ezigbo iguzogide sọlfọ

Ígwè, chromium na aluminom nwere ezigbo nguzogide nchara megide ikuku nwere sọlfọ na mgbe ihe ndị nwere sọlfọ merụrụ elu ahụ, ebe nickel na chromium ga-emebi nke ukwuu.

8, Ọnụ ego dị ọnụ ala

Iron-chromium-aluminum dị ọnụ ala karịa nickel-chromium n'ihi na ọ nweghị nickel dị ụkọ.

Ihe ọghọm:

1, Ike dị ala na oke okpomọkụ

Oke ike ya na-abawanye ka okpomọkụ na-arị elu. Mgbe okpomọkụ karịrị 1000℃, ihe ahụ ga-agbatị nwayọ nwayọ n'ihi ibu ya, nke ga-akpata mgbanwe nke ihe ahụ.

2, Ọ dị mfe iji nweta nnukwu mgbawa

Mgbe ejiri ya mee ihe n'okpomọkụ dị elu ruo ogologo oge ma jụọ oyi n'ime ọkụ, ọ na-agbawa agbawa ka ọka ahụ na-eto, a pụghịkwa ịgbagọ ya n'ọnọdụ oyi.

3, Magnetik

Ngwakọta fecral agaghị enwe ike ịnweta ihe karịrị 600°C.

4, Nguzogide nrụrụ aka adịghị ike karịa alloy nicr.

Ọ bụrụ na ị nwere ozi ndị ọzọ, biko kpọtụrụ anyị.

Anyị nwere ike imepụta ihe dị ka tọn 200 nke ngwaahịa fecral alloy, ọ bụrụ na ịchọrọ, biko nweere onwe gị ịkpọtụrụ anyị.
