① Ọnụọgụ abụọ ahụ na mmalite nke nọmba ígwè na-egosi ọdịnaya carbon nke ígwè ahụ, na nkezi carbon ọdịnaya nke puku ole na ole, dị ka 40Cr, 30CrMo alloy steel pipe.
② A na-egosipụtakarị ihe ndị bụ isi alloying na ígwè, ma e wezụga ụfọdụ ihe microalloying, site na ọtụtụ pasent.Mgbe nkezi ihe alloy dị ihe na-erughị 1.5%, ọ bụ naanị akara mmewere ka a na-edekarị akara na nọmba igwe, mana ọ bụghị ọdịnaya.Otú ọ dị, n'ọnọdụ pụrụ iche, ọ dị mfe mgbagwoju anya, ọnụ ọgụgụ "1" nwere ike ịkara akara mgbe akara mmewere, dị ka nọmba ígwè "12CrMoV" na "12Cr1MoV", ọdịnaya chromium nke mbụ bụ 0.4-0.6%, na nke ikpeazụ bụ 0.9-1.2%.Ihe niile ọzọ bụ otu.Mgbe nkezi alloying mmewere ọdịnaya ≥1.5%, ≥2.5%, ≥3.5%……“, akara mmewere kwesịrị ka akara mgbe ọdịnaya, nwere ike na-egosipụta dị ka 2, 3, 4…… Etc. Dịka ọmụmaatụ, 18Cr2Ni4WA.
③ Alloy ọcha dị ka vanadium V, titanium Ti, aluminum AL, boron B na obere ụwa RE na ígwè bụ nke microalloying ọcha.Ọ bụ ezie na ọdịnaya dị ntakịrị, a ka kwesịrị ka akara ha na nọmba ígwè.Dịka ọmụmaatụ, na ígwè 20MnVB.Vanadium bụ 0.07-0.12% na boron bụ 0.001-0.005%.
④ "A" kwesịrị ịgbakwunye na njedebe nke ọnụ ọgụgụ nchara nke ígwè dị elu iji chọpụta ọdịiche dị na nchara dị elu n'ozuzu ya.
⑤ Special ebumnuche alloy structural steel, nchara nọmba nchara (ma ọ bụ suffix) na-anọchite anya ebumnuche nke akara nchara.Dịka ọmụmaatụ, nchara 30CrMnSi nke a na-eji eme ihe maka skru bụ ML30CrMnSi.
Teknụzụ nrụpụta:
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
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
