Zvidhinha Zvakanakisisa zveAOD Furnaces - Mhando, Mabhenefiti & Mashandisirwo

Choto cheAOD (Argon Oxygen Decarburization) ndicho chinhu chikuru chinoshandiswa pakugadzira simbi isina ngura uye simbi yemhando yepamusoro. Nzvimbo dzekuchenesa AOD dzine tembiricha yakakwira zvakanyanya, kupisa kwakanyanya, ngura yakasimba yealkaline slag, uye kukweshana kwemakanika. Mamiriro aya ekushanda akaomarara anoita kuti zvidhinha zveAOD zvinoramba kushandiswa muchoto zvive chimwe chezvinhu zvakakosha zvinoshandiswa mumiti yesimbi. Kusarudza mhando dzezvidhinha zvinoramba kushandiswa kunowedzera hupenyu hwekushanda kwechoto, kunoderedza mari yekutsiva inoramba kushandiswa, uye kunovandudza kugadzirwa kwesimbi.

Kana uchitsvaga nzira dzekugadzirisa midziyo yeAOD yakasimba uye isingadhuri, kunzwisisa mhando dzezvidhinha zveAOD zvinoramba kushanda kwakakosha. Pazasi tinokuzivisa nezvezvidhinha zvinoramba kushanda zvakanyanya uye zvinoshanda zvakanyanya zvemidziyo yeAOD.

Zvidhinha zvemagnesia chrome zvakasungirirwa zvakananga ndizvo zvinhu zvechinyakare uye zvakavimbika zvemachira eAOD. Zvakagadzirwa ne magnesia yakasanganiswa ne chrome ore yakachena kwazvo kuburikidza nekupisa kwakanyanya, zvidhinha izvi zvine porosity shoma, huwandu hwakawanda, uye kuramba slag kwakanyanya. Zvinoramba zvakakwana alkaline steel slag erosion uye thermal shock kakawanda, izvo zvinowanzoonekwa mukugadzirisa kweAOD. Zvakanakira nzvimbo dzekiyi dzinopfekwa zvakanyanya dzinosanganisira AOD furnace slag line, nzvimbo yetuyere uye side wall working lining, zvidhinha izvi zvinodzivirira spalling ye lining uye kukuvara kwekupinda.

Zvidhinha zveMagnesia calcium, zvinozivikanwawo sezvidhinha zvedolomite refractory, zvave nzira dzakakurumbira dzekuchengetedza nharaunda panzvimbo pezvidhinha zvemagnesia chrome. Zvisina kusvibiswa nechromium, zvidhinha izvi zvine simba rakanaka rekupisa uye zvinodzivirira alkaline slag zvakanyanya. Chikamu checalcium oxide chinogona kunyudza sarufa netsvina musimbi yakanyungudutswa, zvichivandudza zvikuru kunaka kwesimbi isingatsvedzi. Vagadziri vazhinji vanoshandisa zvidhinha izvi pasi peAOD furnace, linings dzinogara kwenguva refu uye zvikamu zvemadziro epamberi, zvichinyatsoenderana nemabasa ekugadzira simbi anoenderera mberi kwenguva refu.

Zvidhinha zvemagnesia zvinoramba kusviba zvakanyanya zvakagadzirirwa nzvimbo dzeAOD dzine ngura shoma uye tembiricha yakagadzikana. Nekusvibiswa kwakaderera zvakanyanya uye chimiro chidiki, zvinopa simba remakanika uye kudzivirira tembiricha yakakwira. Zvidhinha izvi zvinoramba kusviba zvisingadhuri zvakanyanya zvinowanzo shandiswa pakuisa pamusoro pechitofu uye machira ekuwedzera, zvichipa dziviriro yakagadzikana uye kuderedza mari yezvinhu zvinoramba kusviba.

Sei Uchifanira Kusarudza Zvidhinha Zvedu zveAOD Refractory zveNyanzvi?

Semugadziri wezvidhinha zvinoramba kushandiswa neAOD, tinodzora zvakanyanya kusarudzwa kwezvinhu zvakabikwa uye maitiro ekugadzira. Zvidhinha zvedu zvese zvinoramba kushandiswa nechoto zvine simba rekudzivirira kupisa, simba rakasimba rekudzivirira ngura uye hupenyu hurefu hwebasa. Tinopa zvidhinha zvinoramba kushandiswa nehukuru hwakajairwa uye hwakagadziriswa kuti zvienderane nemhando dzakasiyana dzechoto cheAOD nemamiriro ekushanda emaindasitiri. Zvigadzirwa zvedu zvinobatsira mafekitori esimbi kuderedza nguva yekushanda kwemidziyo, kuderedza mari yekugadzirisa uye kuwedzera mabhenefiti ekugadzira.

Pfungwa Dzekupedzisira

Nzvimbo dzakasiyana dzeAOD dzinoda zvidhinha zvakafanana zvinoramba kushanda. Zvidhinha zveMagnesia chrome, zvidhinha zvedolomite uye zvidhinha zvemagnesia zvakachena zvakakwana zvinofukidza zvese zvinodiwa pakugadzira simbi zveAOD. Kuti uwane mhinduro dzemhando yepamusoro dzeAOD furnace dzinoramba kushanda zvakanaka, inzwa wakasununguka kutibata kuti uwane makotesheni akagadzirwa uye nhungamiro yehunyanzvi.
