Mgbidi ígwè ọkpọkọ nke 20-426
Iwebata ngwaahịa:
Dịka ọmụmaatụ, 40Cr.(Ọdịnaya carbon nke 35CrMo alloy ígwè ọkpọkọ bụ 0.32 ~ 0.40, silicon 0.17 ~ 0.37, manganese 0.40 ~ 0.70, molybdenum 0.15 ~ 0.25, chromium 0.80 ~ 1.10)
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.
Alloy tube na enweghị nkebi tube ma nwere mmekọrịta na iche, enweghị ike mgbagwoju anya.
Alloy pipe bụ ọkpọkọ ígwè dị ka ihe mmepụta ihe (ya bụ, ihe) si kọwaa, dị ka aha na-egosi na ọ bụ ọkpọkọ alloy;Na enweghị nkebi ọkpọkọ bụ ígwè anwụrụ dị ka mmepụta usoro (enweghị nkebi) kọwaa, dị iche iche si enweghị nkebi ọjà bụ welded ọkpọkọ, gụnyere ogologo onuete welded ọkpọkọ na gburugburu ọkpọkọ.
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
