China ASTM A53 Gr.B na-ekpo ọkụ Rolled Carbon Steel Pipe
Nkọwa dị mkpirikpi:
Nke a Alloy Steel Pipe na 12cr1MOV Material bụ igwe anaghị agba nchara nke enwere ike iji ya na mmanụ ala, kemịkalụ, ọkụ eletrik na ngwa ọkụ.Ọ nwere njirimara nke nguzogide oyi, nguzogide okpomọkụ na nguzogide corrosion.12Cr1MoV bụ ụdị ọkpọkọ alloy.Ebumnuche bụ isi bụ ime akụkụ nhazi ígwè n'ime ọkụ ọkụ.
N'ịgbaso ụkpụrụ nke "ịdị mma, ọrụ, arụmọrụ na uto", anyị enwetala ntụkwasị obi na otuto sitere n'aka ndị ahịa ụlọ na nke mba ụwa maka China ASTM A53 Gr.B Hot Rolled Carbon Seamless Steel Pipe, Maka ajụjụ ndị ọzọ ma ọ bụ ị nwere ike ịnwe ajụjụ ọ bụla gbasara ngwa ahịa anyị, jide n'aka na ịla azụ ịkpọ anyị.
N'ịgbaso ụkpụrụ nke "ịdịmma, ọrụ, arụmọrụ na uto", anyị enwetawo ntụkwasị obi na otuto sitere n'aka ndị ahịa ụlọ na nke mba ụwa makaChina Steel Pipe na Carbon Pipe, Anyị na-amụbawanye òkè ahịa mba ụwa anyị dabere na ihe ndị dị mma, ọrụ magburu onwe ya, ọnụ ahịa ezi uche na nnyefe oge.Biko kpọtụrụ anyị n'oge ọ bụla maka ozi ndị ọzọ.
The ọrụ okpomọkụ bụ 580 ℃, na ígwè efere a chọrọ ka nwere elu okpomọkụ ntachi obi ike.A na-ebufe efere ígwè ahụ n'ọnọdụ nkịtị na nke dị ọkụ.12Cr1MoVG alloy pipe dabeere na elu-edu carbon structural ígwè, na otu ma ọ bụ ọtụtụ alloy ọcha na-agbakwunyere n'ụzọ kwesịrị ekwesị iji melite n'ibu Njirimara, siri ike na hardening nke ígwè.Ngwaahịa nke ígwè dị otú ahụ na-achọkarị ọgwụgwọ okpomọkụ (normalizing or quenching and tempering);Akụkụ na ihe ndị e mere n'ime ha na-achọkarị ka a na-emenyụ ọkụ na tempering ma ọ bụ ọgwụgwọ kemịkalụ elu (carburizing, nitriding, wdg), nkwụsị elu ma ọ bụ nkwụsị elu ugboro ugboro tupu ejiri ya.Ya mere, dị ka ihe mejupụtara kemịkalụ dị iche iche (karịsịa carbon ọdịnaya), usoro ọgwụgwọ okpomọkụ na ngwa, a ga-ekewa nchara ndị dị otú ahụ na carburized, Quenched na tempered na nitrided steels.
Nke mbụ, enwere ike ịmegharị ya 100%, nchekwa ike na nchekwa gburugburu ebe obibi.
Nke abụọ, ọ nwere nnukwu plasticity na enwere ike iji ya mee ihe maka mmepụta na nhazi nke abụọ.
Nke atọ, ọ nwere ezigbo thermal conductivity na nnukwu okpomọkụ creep ike.
Nke anọ, ọ nwere ezigbo nguzogide oxidation na nguzogide corrosion.
Nke ise, ọ nwere ezigbo ọrụ nhazi oyi na ọkụ.
12Cr1MoVG bụ ụdị chromium molybdenum alloy ígwè ọkpọkọ, nke bụ isi chemical components bụ carbon 0.08-0.15, silicon 0.17-0.37, manganese 0.40-0.70, phosphorus bụghị ihe karịrị 0.035, sọlfọ ọ bụghị karịa 0.030.0.0.9 chromium. molybdenum 0.25-0.35, alum 0.15-0.30, wdg.
Nke mbụ, a na-ejikarị emepụta tubes alloy dị elu maka ikpo ọkụ na-ekpo ọkụ nke mmiri tube na-ekpo ọkụ na nrụgide dị elu na n'elu.
Nke abụọ, a na-eji ya eme ihe na igwe ọkụ ọkụ, ndị nkụnye eji isi mee na ọwa mmiri mmiri nke nnukwu nrụgide ụlọ, nrụgide dị elu na ọdụ ụgbọ mmiri subcritical.
Nke atọ, nnukwu dayameta ọkpọkọ na-bụ-eji dị ka nkụnye eji isi mee na Main Steam Conduits na uzuoku parameters n'okpuru 565 ℃.
Mbụ, na-ekpo ọkụ rolling (extrusion enweghị nkebi nchara anwụrụ) usoro eruba:
Gburugburu tube billet → kpo oku → ịkpọpu → mpịakọta mpịakọta atọ na-atụgharị, na-agbagharị ma ọ bụ extrusion → ọkpọkọ ọkpọkọ → nha (ma ọ bụ ibelata) → jụrụ oyi → billet → ịgbatị → ule hydrostatic (ma ọ bụ nchọpụta ntụpọ) → akara → nkwakọba ihe.
Nke abụọ, oyi ịbịaru (na-atụgharị) enweghị nkebi ígwè anwụrụ usoro eruba:
Gburugburu tube billet → kpo oku → ịkpọpu → isi → annealing → pickling → mmanụ mkpuchi (ọla kọpa) → multi pass cold draw (oyi rolling) → billet tube → ọgwụgwọ okpomọkụ → ịgbatị → hydrostatic test (ma ọ bụ nchọpụta ntụpọ) → akara → nkwakọba ihe.
