Na-ere ọkụ maka 12Cr1MoV Alloy enweghị nkebi ígwè Pipe High Pressure Boiler Tube
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.
Kedu nke nwere usoro nchịkwa sayensị zuru oke, ezigbo mma na ezigbo okpukpe, anyị na-enweta aha ọma ma nọrọ n'ọhịa a maka ire ere ọkụ maka 12Cr1MoV Alloy Seamless Steel Pipe High Pressure Boiler Tube, ọ bụrụ na ị nwere ajụjụ ọ bụla ma ọ bụ chọọ itinye mbụ. zụta jide n'aka na ị gaghị echere ijide anyị.
Nke nwere usoro njikwa sayensị zuru oke, ezigbo mma na okpukperechi dị mma, anyị na-enweta aha ọma ma were mpaghara a makaChina 12Cr1MoV Igwe mmiri ọkụ dị elu, Ihe ị chọrọ bụ ihe anyị na-achụso.Anyị ji n'aka na ngwaahịa anyị ga-ewetara gị ọkwa ọkwa mbụ.Na ugbu a na-enwe olileanya ịkwalite mmekọrịta enyi gị na ụwa niile.Ka anyị jikọ aka ọnụ na-arụkọ ọrụ na uru otu!
The ọrụ okpomọkụ bụ 580 ℃, na ígwè efere a chọrọ ka nwere elu okpomọkụ ntachi obi ike.A na-ebufe efere ígwè ahụ na 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 si dị (karịsịa ọdịnaya carbon), usoro ọgwụgwọ okpomọkụ na ngwa, enwere ike kewaa nchara ndị dị otú ahụ ka ọ bụrụ 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.
