Njọ elu elu nke tubes enweghị nkebi (smls):

1. Ntụpọ mpịachi
Nkesa na-ezighi ezi: Ọ bụrụ na ebu slag na-anọgide na mpaghara n'elu nkedo nkedo na-aga n'ihu, ntụpọ mpịachi miri emi ga-apụta n'elu elu nke tube a na-akpọgharị, a ga-ekesa ha ogologo oge, "ihe mgbochi" ga-apụtakwa n'akụkụ ụfọdụ nke elu. . The mpịachi omimi nke akpọrepu tube bụ banyere 0.5 ~ 1mm, na nkesa mpịachi ntụziaka bụ 40 ° ~ 60 °.

2. Nnukwu mpịachi ntụpọ
Nkesa ogologo: ntụpọ mgbawa na nnukwu ntụpọ mpịaji na-apụta n'elu slab nkedo na-aga n'ihu, a na-ekesa ha ogologo oge. Ọtụtụ n'ime omimi mpịachi n'elu tubes ígwè enweghị nkebi dị ihe dịka 1 ruo 10 mm.

3. Obere ntụpọ mgbape
Mgbe ị na-anwale tubes nchara na-enweghị nkebi, enwere ntụpọ dị n'elu mgbidi dị n'èzí nke ọkpọ ahụ nke anya gba ọtọ enweghị ike ịhụ. Enwere ọtụtụ ntụpọ mpịachi dị n'elu ọkpọkọ igwe anaghị agba nchara, omimi miri emi dị ihe dị ka 0.15mm, a na-ekpuchi elu igwe nke igwe anaghị agba nchara, yana akwa decarburization n'okpuru ígwè oxide. omimi dị ihe dịka 0.2mm.

4. Mpempe mpe mpe akwa
Enwere ntụpọ ahịrị n'elu elu nke tube nchara na-enweghị ntụpọ, na njirimara ndị a kapịrị ọnụ bụ omimi miri emi, oghere sara mbara, ala a na-ahụ anya, na obosara mgbe niile. Enwere ike ịhụ mgbidi dị n'èzí nke akụkụ obe nke ọkpọkọ ígwè na-enweghị ntụpọ na ncha na omimi nke <1mm, nke dị n'ụdị oghere. Mgbe ọgwụgwọ okpomọkụ gasịrị, e nwere oxidation na decarburization na nsọtụ nke uzo nke ọkpọkọ.

5. Ụjọ ntụpọ
Enwere ntụpọ olulu na-emighị emi n'elu elu nke tube nchara na-enweghị ntụpọ, nwere nha na mpaghara dị iche iche. Ọ dịghị oxidation, decarburization, na nchịkọta na inclusions gburugburu olulu; anụ ahụ gburugburu olulu na-squeezed n'okpuru elu okpomọkụ, na plastic rheological àgwà ga-apụta.

6. Na-emenyụ mgbawa
A na-eme ọgwụgwọ okpomọkụ na-ekpo ọkụ na nke na-ekpo ọkụ na tube nchara na-enweghị ntụpọ, na ogologo mgbawa dị mma na-apụta n'elu elu, nke a na-ekesa na ibe nwere ụfọdụ obosara.

Nrụrụ elu dị n'ime nke tubes enweghị nkebi:

1. Convex hull ntụpọ
Njirimara Macroscopic: Mgbidi dị n'ime nke tube nchara na-enweghị ihe ọ bụla ekesawo obere ntụpọ ogologo ogologo oge, na ịdị elu nke obere ntụpọ convex ndị a dị ihe dịka 0.2mm ruo 1mm.
Ihe e ji mara microscopic: Enwere ntinye dị yinye-dị ka isi awọ na ọdụ, n'etiti na gburugburu convex hull n'akụkụ abụọ nke mgbidi dị n'ime nke akụkụ obe nke ọkpọkọ ígwè na-enweghị ntụpọ. Ụdị yinye ojii na-acha ntụ ntụ nwere calcium aluminate na obere ihe mejupụtara oxides (iron oxide, silicon oxide, magnesium oxide).

2. ntụpọ kwụ ọtọ
Atụmatụ macroscopic: Ụdị ntụpọ ziri ezi na-apụta na tubes ígwè na-enweghị ntụpọ, nke nwere ụfọdụ omimi na obosara, dị ka ncha.

Njirimara microscopic: Ntugharị dị na mgbidi dị n'ime nke akụkụ obe nke tube nchara na-enweghị ntụpọ dị n'ụdị oghere nke nwere omimi nke 1 ruo 2 cm. Oxidative decarburization anaghị apụta na nsọtụ nke uzo. The gburugburu anụ ahụ nke uzo nwere àgwà nke metal rheology na deformation extrusion. A ga-enwe microcracks n'ihi oke extrusion n'oge usoro nhazi.
