Ukwenza ngcono nokwenza kahle inqubo yokuncibilikisa insimbi engagqwali ye-ultra-low carbon

Insimbi engagqwali ye-Ultra-low carbon martensitic (06Cr13Ni46Mo kanye ne-06Cr16Ni46Mo) yinto ebalulekile evame ukusetshenziselwa umqhele ongaphezulu, iringi ephansi, izindwani kanye nezinkomba zokuhola zezingxenye ezibalulekile zama-turbines wokubacindezela. Lolu chungechunge lwezinto zensimbi engagqwali lunzima ekuncibilikiseni ubuchwepheshe futhi lunezidingo eziphezulu zekhwalithi yomkhiqizo. Ikakhulukazi lapho kukhiqizwa i-Three Gorges hydropower unit, izinkampani ezintathu ezinkulu ezikhiqiza imishini yokuphehla ugesi zasekhaya sezisungule ubuchwepheshe namazinga okukhiqiza amandla aphehlwa ngamanzi ngokwethula ubuchwepheshe namazinga okukhiqiza ugesi wasekhaya nowangaphandle. Izinga le-Three Gorges lezinto ezisemqoka zemishini yamandla kagesi (izidingo ezibonakalayo ezithintekayo kuleli zinga zimelela izinga eliphakeme kakhulu embonini yasekhaya). Izidingo zokwakheka kwensimbi encibilikile yilezi: ω (C) ≤0.05%, ω (P) ≤0.028%, ω (S) ≤0.015%, ω (Si) ≤1.00%, ω (Mn) ≤1.00%, ω ( Cr) -12.45%, ω (Ni) = 3.5 ～ 4.5%, ω (Mo) = 0.40 ～ 1.00%, ω (O) ≤80 × 10-6, ω (N) -150 × 10-6, ω ( H) ≤3 × 10-6.

Ukuze kukhiqizwe ukukhishwa kwensimbi engenasici esezingeni eliphakeme, abakhiqizi basekhaya nabangaphandle basebenzisa kakhulu isithando somlilo kagesi + sokucwenga (i-AOD, VOD, LF, njll.) Ukukhiqiza. Phakathi kwabo, ukusetshenziswa kwe-AOD ukuncibilikisa insimbi engagqwali sekuyinto ehamba phambili yokuhluza insimbi engagqwali. Njengamanje, lapho abakhiqizi basekhaya nabangaphandle bekhiqiza lolu chungechunge lwezinto zensimbi ezingenasici, imifantu kungenzeka kakhulu ngesikhathi sokukhiqizwa nasekucutshungweni okulandelayo, futhi imifantu ivela ngezikhathi ezithile ngesikhathi sokusetshenziswa. Ngakho-ke, ukuze kuthuthukiswe ikhwalithi yalolu chungechunge lokusakazwa kwempahla, kuyadingeka ukwenza ngcono ukusebenza okuphelele kokuphonswa ngokuthuthukisa ikhwalithi yemvelo yensimbi encibilikisiwe.

Abasebenzi bezobuchwepheshe be-MINGHE Group babhekane nezinkinga zesikhathi eside se-decarburization, ukusetshenziswa okukhulu kwe-oxygen, izinga lokushisa eliphakeme lokushisa, nesikhathi eside sokuhlala esinezinga lokushisa eliphezulu enkambisweni yokuqala yokuncibilikisa insimbi engagqwali. Ngokuthuthuka kwenqubo nokusetshenziswa kwesithando sokucwenga se-AOD, ikhwalithi yensimbi encibilikisiwe ithuthukisiwe.

Njengoba sonke sazi, ukhiye wokushaywa komoya-mpilo kanye ne-decarburization ukulawula ukusabela kwe-oxygen ensimbi encibilikisiwe nge-carbon, chromium, silicon, manganese nezinye izinto. Ngokususelwa kumgomo wensimbi yokusansimbi, kuhlanganiswe nokusetshenziswa kwe-AOD, ochwepheshe bathuthukise futhi balungiselela inqubo eyinhloko yenqubo yokuncibilikisa insimbi engagqwali yokuqala.

Indlela ye-AOD isebenzisa igesi ye-argon ne-oxygen ukushaya insimbi encibilikile echibini elincibilikisiwe ohlangothini lwesithando somlilo ngesimo segesi elixubekile. Ngesikhathi senqubo yokushaya, ingcindezi engaphelele ye-CO ihlanjululwa yi-argon futhi yehlisiwe, okusiza kakhulu ukwenziwa kwe-decarburization nokulondolozwa kwe-chromium yensimbi engagqwali ngesikhathi sokuncibilikisa. Esigabeni sokuncishiswa kokucwengwa kwe-AOD, ngenxa yokwengezwa kwe-ferrosilicon ne-limestone slag ye-deoxidation, kanye nokuxokozela okukhulu kwe-argon, insimbi encibilikisiwe ingachithwa ngokujulile; ukuvusa okukhulu kwe-argon ngesikhathi sokucwengwa kwe-AOD kungakhuthaza ukuhlukaniswa kwama-oxide ensimbi encibilikisiwe, Kukhuphuka, ukuhlanzeka kwensimbi encibilikisiwe kuyathuthukiswa, ngakho-ke okuqukethwe kokufakwa kwensimbi encibilikile kuncane, futhi cishe akukho izinhlayiya ezifakiwe. Ifomu eliyinhloko lama-inclusions lishintshile ukusuka kusithando somlilo sikagesi se-manganese silicate saba yi-calcium silicate.

Ngaphezu kwalokho, indlela ye-AOD futhi ingasusa ukuhola kusuka ensimbi ngesikhathi senqubo yokushaya. Ucwaningo lukhombisile ukuthi inani elithile lomthofu engagqwali lizothinta ukusebenza kwalo okushisayo, kepha ngemuva kokushaywa yi-AOD, i-ω (Pb) ensimbi eqediwe ingaphansi kuka-10 × 10-6, engeke ithinte ukusebenza kwensimbi kube bonke.

Ngokuthuthuka kwenqubo nokusetshenziswa kwe-AOD, kutholakala insimbi ephezulu encibilikisiwe. Usebenzisa ukwakheka kwe-Si-Ca ne-Si-Fe, insimbi encibilikisiwe ω (O) yehliselwa ku-80 × 10-6; umcako osetshenzisiwe usetshenziselwa ukuqinisa ukungcola, ukuze i-ω (S) yehliswe ibe ngaphansi kuka-0.015%, okuthuthukisa kakhulu ukuhlanzeka kwensimbi encibilikisiwe, futhi ihlangabezane nezidingo zokuncibilika kokwakheka kanye nezinkomba ezahlukahlukene zomzimba nezamakhemikhali; okuqukethwe kwezingxenye zegesi eziyingozi kanye nokufakwa kwe-oxyde eyindilinga ngensimbi encibilikisiwe (isilinganiso esiyindilinga se-oxide singeqi ku-2.0) kuncishisiwe kakhulu; Ukuthuthuka kokuhlanzeka kwensimbi encibilikisiwe kuthuthukisa ikhono le-matrix yokukhipha ukumelana nemifantu

Sicela ugcine umthombo nekheli lale ndatshana ukuze uphinde uprintwe: Ukwenza ngcono nokwenza kahle inqubo yokuncibilikisa insimbi engagqwali ye-ultra-low carbon
