Zvinhu zvinoramba zvichishandiswa mumutsara we slag wepakutanga ladle zvakabatanidzwa zvakananga ne magnesia-chrome zvidhinha, kunyunguduka kwemagetsi uye zvino zvakasanganiswa ne magnesia-chrome zvidhinha uye zvimwe zvidhinha zvepamusoro zve alkaline. Mushure mokunge MgO-C zvidhinha zvakashandiswa zvakabudirira pavashanduri, zvidhinha zveMgO-C zvakashandiswawo mumutsetse we slag wekunatsa ladle, uye zvibereko zvakanaka zvakawanikwa. nyika yangu neJapan kazhinji vanoshandisa resin-bonded MgO-C zvidhinha zvine kabhoni ye12% kusvika 20%, nepo Europe ichinyanya kushandisa asphalt-bonded MgO-C zvidhinha, ine kabhoni inokwana 10%.
Iyo Kokura Steel Works yeSumitomo Metal Corporation muJapan yakashandisa zvidhinha zveMgO-C zvine MgO zve83% uye C zvemukati zve14-17% kutsiva zvakasungwa zvakananga magnesia-chrome zvidhinha mumutsara weVAD slag, uye hupenyu hwebasa re slag. mutsara wakawedzerwa kubva pamakumi maviri kusvika ku30-32 nguva [9]. Iyo LF yekunatsa ladle yeSendai Steel Plant muJapan yakashandisa MgO-C zvidhinha kutsiva magnesia-chrome zvidhinha, uye hupenyu hwebasa reiyo slag mutsara hwakawedzerwa kubva ku20-25 nguva kusvika makumi mana, kuwana mhedzisiro yakanaka. Osaka Ceramics Refractory Co., Ltd. yakadzidza mhedzisiro yekabhoni yemukati uye antioxidant mhando pane oxidation kuramba, slag kuramba uye tembiricha yekuchinjika kusimba kweMgO-C zvidhinha. Chidzidzo chacho chinoratidza kuti MgO-C zvidhinha zvakagadzirwa nemusanganiswa we fused magnesia uye sintered magnesia, ine 15% phosphorus graphite uye shoma shoma ye magnesium-aluminium alloy se antioxidants, ine basa rakanaka rekushandisa. Kana ichishandiswa mumutsara we100-ton LF ladle slag, huwandu hwekukuvadza hunoderedzwa ne20-30% zvichienzaniswa neMgO-C zvidhinha zvine kabhoni ye18% uye isina antioxidant, uye avhareji yekukukurwa kwevhu i1.2-1.3 mm / choto [1].
Sezvo nyika yangu yakacheneswa ladle slag line zvidhinha zvakatora MgO-C zvidhinha pachinzvimbo che magnesia-chrome zvidhinha, mhedzisiro yekushandisa yave pachena. Baosteel Group Corporation's 300t ladle slag line yakatanga kushandisa MT-14A magnesia-carbon zvidhinha muna Chikunguru 1989, uye hupenyu hwemutsetse we slag hwakaramba hunopfuura ka100; iyo 150T electric furnace ladle slag line inoshandisa yakaderera-kabhoni magnesia-kabhoni zvidhinha kunyungudutsa tambo yesimbi, ine tembiricha yekurova ye1600 ℃ ~ 1670 ℃, iyo yakawana mhedzisiro iri pachena.
Kambani yedu inyanzvi mukugadzira magnesia kabhoni zvidhinha, aluminium-magnesia kabhoni zvidhinha, zvisiri-kabhoni zvidhinha zveladles dzakanatswa, aluminium-silicon carbide kabhoni zvidhinha zvematangi etorpedo, uye zvidhinha zvitsva zvisina kabhoni magnesia uye akasiyana amorphous refractories, sekugadzirisa. uye pfuti zvinhu zvevashanduri, mavira emagetsi uye marashi. Isu tinopawo zvigadzirwa zvakaumbwa-kuzunguzika, senge ladle mhepo zvidhinha, mhepo-inopindika nozzle chigaro zvidhinha, nozzle chigaro zvidhinha uye prefabricated zvinhu. Isu takagadzira kuita bhizinesi rakazara refractory rinobatanidza tsvakiridzo yezvinyorwa, kugadzirisa kwakadzama uye kutengeserana. Rabhoritari yedu ine yakazara seti yekuyedza uye yekuongorora michina. Midziyo yedu inogona kugadzira zvigadzirwa, zvigadzirwa zvapera, kuyedza uye kuongorora, uye kugadzira zvigadzirwa zvitsva. Isu tinotenda kuti sainzi uye tekinoroji ndiyo gwara redu. Naizvozvo, takawana tekinoroji yepamusoro kumba nekune dzimwe nyika, tichiramba tichivandudza mhando yechigadzirwa, zvesainzi uye tekinoroji uye kugadzikana kwemukati, nekudaro tichivandudza tekinoroji yekugadzira uye kugara tichivandudza michina yedu yekugadzira. Isu tinopa huwandu hwakazara hwehunyanzvi masevhisi zvichienderana nehukuru uye tekinoroji paramita yevashanduri, emagetsi arc furnaces uye ladles zvinoenderana nezvinodiwa nevatengi.

/ Muna 2006, fekitori yedu yakavambwa muYuzhou, iyo mbishi base.High bauxite ore isanganiswa yakakamurwa colloidal inoumbwa nealuminium hydroxides uye mareshiyo akasiyana. High-alumina bauxite muindastiri refractory inowanzoreva bauxite ore ine calcined Al₂O₃ yemukati yakakura kupfuura 48% uye yakaderera Fe₂O₃ yemukati.
