Ibisabwa muri rusange kubikoresho byangiritse kumatara ya arc amashanyarazi ni:
(1) Kwanga bigomba kuba hejuru. Ubushyuhe bwa arc burenga 4000 ° C, naho ubushyuhe bwo gukora ibyuma ni 1500 ~ 1750 ° C, rimwe na rimwe bukagera kuri 2000 ° C, bityo ibikoresho byo kwinaniza birasabwa kugira ubushake buke.
(2) Ubushyuhe bworoheje munsi yumutwaro bugomba kuba hejuru. Itanura ry'amashanyarazi rikora mugihe cy'ubushyuhe bwo hejuru, kandi umubiri w'itanura ugomba kwihanganira isuri y'ibyuma bishongeshejwe, bityo ibikoresho byo kuvunika bisabwa kugira umutwaro mwinshi woroshye ubushyuhe.
(3) Imbaraga zo guhonyora zigomba kuba nyinshi. Itanura ryamashanyarazi ryatewe ningaruka zumuriro mugihe cyo kwishyuza, umuvuduko uhoraho wibyuma bishongeshejwe mugihe cyo gushonga, isuri yimyanda yicyuma mugihe cyo kuyikubita, hamwe no kunyeganyega kwa mashini mugihe gikora. Kubwibyo, ibikoresho byo kwinaniza birasabwa kugira imbaraga zo guhonyora.
(4) Ubushyuhe bwumuriro bugomba kuba buto. Kugirango ugabanye ubushyuhe bw itanura ryamashanyarazi no kugabanya ingufu zamashanyarazi, ibikoresho bivunika birasabwa kugira ubushyuhe buke bwumuriro, ni ukuvuga ko coefficente yumuriro igomba kuba nto.
(5) Guhagarika ubushyuhe bigomba kuba byiza. Mu minota mike uhereye ku gukanda kugeza kwishyuza mu gukora itanura ry'amashanyarazi, ubushyuhe buragabanuka cyane kuva kuri 1600 ° C kugeza munsi ya 900 ° C, bityo ibikoresho byo kuvunika birasabwa kugira ubushyuhe bwiza.
(6) Kurwanya ruswa ikomeye. Mugihe cyo gukora ibyuma, slag, gaze y itanura nicyuma gishongeshejwe byose bigira ingaruka zikomeye ziterwa nisuri kubikoresho bivunika, bityo ibikoresho byo kuvunika birasabwa kugira imbaraga zo kurwanya ruswa.
Guhitamo ibikoresho byangiritse kurukuta rwuruhande
Ubusanzwe amatafari ya MgO-C akoreshwa mu kubaka inkuta zo ku ziko ry’amashanyarazi adafite inkuta zikonjesha amazi. Ahantu hashyushye no kumurongo hafite serivisi zikomeye cyane. Ntibishobora kwangirika cyane no kwangirika nicyuma gishongeshejwe nicyuma, kimwe ningaruka zikoreshwa muburyo bwa mashini mugihe hongeweho ibisigazwa, ariko kandi bigaterwa nimirasire yumuriro ituruka kuri arc. Kubwibyo, ibi bice byubatswe n'amatafari ya MgO-C hamwe nibikorwa byiza.
Kurukuta rwuruhande rwitanura ryamashanyarazi hamwe nurukuta rukonje rwamazi, kubera gukoresha tekinoroji yo gukonjesha amazi, umutwaro wubushyuhe uriyongera kandi uburyo bwo gukoresha burakomeye. Kubwibyo, amatafari ya MgO-C afite imbaraga zo kurwanya slag, guhagarika ubushyuhe bwumuriro hamwe nubushyuhe bwo hejuru bwumuriro bigomba guhitamo. Ibirimo bya karubone ni 10% ~ 20%.
Ibikoresho byangiritse kurukuta rwuruhande rwamashanyarazi yumuriro mwinshi
Urukuta rw'uruhande rw'amashyanyarazi akomeye cyane (itanura rya UHP) rwubatswe ahanini n'amatafari ya MgO-C, kandi ahantu hashyushye hamwe n'umurongo wa slag hubatswe n'amatafari ya MgO-C afite imikorere myiza (nka matrix ya karubone yuzuye MgO-C amatafari). Gutezimbere cyane ubuzima bwa serivisi.
Nubwo urukuta rw'itanura rwaragabanutse kubera kunoza uburyo bwo gukoresha itanura ry'amashanyarazi, biracyagoye ko ibikoresho bivunika byongera igihe cya serivisi ahantu hashyushye mugihe gikora mugihe cyo gushongesha itanura rya UHP. Kubwibyo, tekinoroji yo gukonjesha amazi yatejwe imbere kandi ikoreshwa. Ku itanura ry'amashanyarazi ukoresheje gukanda EBT, ahantu hakonje amazi agera kuri 70%, bityo bikagabanya cyane ikoreshwa ryibikoresho bivunika. Ikoranabuhanga rigezweho ryo gukonjesha risaba amatafari ya MgO-C hamwe nubushyuhe bwiza bwumuriro. Asfalt, amatafari ya magnesia hamwe n'amatafari ya MgO-C (ibirimo karubone 5% -25%) bikoreshwa mukubaka inkuta zomuri itanura ryamashanyarazi. Mugihe gikabije cya okiside, hiyongeraho antioxydants.
Ahantu hotspot yangiritse cyane kubera reaction ya redox, amatafari ya MgO-C hamwe na kristaline nini yahujwe na magnesite nkibikoresho fatizo, ibirimo karubone irenga 20%, hamwe na matrike yuzuye ya karubone ikoreshwa mubwubatsi.
Iterambere rigezweho ryamatafari ya MgO-C kumatanura ya UHP ni ugukoresha umuriro mwinshi hanyuma ugaterwa hamwe na asfalt kugirango ubyare amatafari ya MgO-C yatewe. Nkuko bigaragara ku mbonerahamwe ya 2, ugereranije n’amatafari atabigenewe, karuboni isigaye y’amatafari ya MgO-C yarashwe nyuma yo gutera asifalt na recarbonisation yiyongera hafi 1%, ububobere bugabanukaho 1%, hamwe n’ubushyuhe bwo hejuru bw’ubushyuhe n’umuvuduko Kurwanya ni Imbaraga zateye imbere cyane, bityo zifite igihe kirekire.
Ibikoresho bya magnesium bivunagura kumatara yumuriro wamashanyarazi
Amashanyarazi y'itanura agabanijwemo alkaline na aside. Iyambere ikoresha ibikoresho byo kwangirika kwa alkaline (nka magnesia na MgO-CaO ibikoresho byo kuvunika) nk'itanura, mugihe iyanyuma ikoresha amatafari ya silika, umucanga wa quartz, icyondo cyera, nibindi byubaka itanura.
Icyitonderwa: Kubikoresho byo gutanura itanura, itanura ryamashanyarazi ya alkaline rikoresha ibikoresho byangiza alkaline, naho itanura ryamashanyarazi rikoresha aside irike.
