Carbon Steel enweghị nkebi ígwè tube - Royal Group

1. Hot Rolling (extrusion enweghị nkebi ígwè ọkpọkọ): gburugburu tube oghere → kpo oku → perforating → atọ elu diagonal rolling, na-aga n'ihu rolling ma ọ bụ extrusion → ịdọpụ → size (ma ọ bụ ibelata) → jụrụ → ịgbatị → hydrostatic ule (ma ọ bụ nyocha) → marking → nchekwa
Ngwa ngwa nke tube na-enweghị nkebi bụ okirikiri tube okirikiri, a na-egbutu nwa embrayo gburugburu wee hazie ya site na igwe na-eto ihe dị ka mita 1 oghere, wee ziga ya na ọkụ site na kpo oku ebufe eriri. A na-etinye billet ahụ n'ime ọkụ ma kpoo ya ihe dịka 1200 degrees Celsius. Mmanụ bụ hydrogen ma ọ bụ acetylene. Njikwa okpomọkụ dị na ọkụ bụ isi nsogbu. Mgbe billet okirikiri ahụ pụtachara, ọkpọ nrụgide na-agba ya. N'ozuzu, onye na-agbapụkarị bụ conical mpịakọta perforator. Ụdị perforator a nwere nrụpụta mmepụta dị elu, àgwà ngwaahịa dị mma, nnukwu oghere na-agbapụta ma nwee ike iyi ụdị ígwè dị iche iche. Mgbe a gbasasịrị ahụ, a na-akpụgharị billet okirikiri ahụ site na diagonal atọ dị elu, mkpụgharị na-aga n'ihu ma ọ bụ extrusion. Mgbe extrusion gasịrị, a ga-ewepụ ọkpọkọ maka nha. Caliper na-atụgharị n'ime ẹmbrayo nchara site na mkpụgharị conical na oke ọsọ iji tụọ oghere wee mepụta ọkpọkọ ígwè. A na-ekpebi dayameta dị n'ime nke ọkpọkọ ígwè site na dayameta dị n'elu ogologo nke ntanye caliper. Mgbe emechara ọkpọkọ ígwè ahụ, ọ na-abanye n'ụlọ elu dị jụụ ma mee ka ọ dị jụụ site na ịgbanye mmiri. Mgbe emechara ọkpọkọ ígwè ahụ, a ga-agbatị ya.
2. oyi-adọkpụ (akpọrela) enweghị nkebi ígwè ọkpọkọ: gburugburu tube oghere → kpo oku → perforation → isi → annealing → pickling → mmanụ (ọla kọpa plating) → multi-agafe oyi ịbịaru (oyi Rolling) → oghere tube → okpomọkụ ọgwụgwọ → ịgbatị → ule hydrostatic (nleba anya) → akara → nchekwa.
Ụzọ ntụgharị nke ịbịaru oyi (na-agbagharị) ọkpọ ígwè na-enweghị ihe ọ bụla dị mgbagwoju anya karịa nke ọkụ na-ekpo ọkụ (extrusion) nchara nchara. Nzọụkwụ atọ mbụ nke usoro mmepụta ha bụ otu ihe. Ihe dị iche site na nzọụkwụ nke anọ, tube gburugburu oghere mgbe ọkpọchara, na isi, annealing. Mgbe ọ gbasasịrị, a na-eji mmiri mmiri acidic pụrụ iche maka pickling. Mgbe a kpochara, a na-etinye mmanụ. Nke a na-esote ọgwụgwọ okpomọkụ pụrụ iche nke tube rebillet mgbe ọtụtụ eserese oyi (mgbagharị oyi). Mgbe ọgwụgwọ okpomọkụ gasịrị, a na-agbatị ya.
