Sintering muchina furidza Kuumbwa uye jira kuwedzera majoini

Sintering Machine pamwe mhepo iridzwe kuburikidza batch mangé rukoko (Figure 3,6.) Uri kuvakwa uye kushanda seizvi. In kamera ane nhoo rukoko mutariri dzinoshandisa vakamanikidzwa mhepo. Kubata kose bazi sintering mumuchina vakapakata utiziro kuunganidzwa kwemari chomubisiro magasi uye pakusika zvakanaka utsanana basa muchitoro. The nzvimbo pasi yokuvanda conditionally kuva zvikamu zviviri: akapfuma gasi (zvikuru rinopfuta mapazi), uye murombo (shure) gasi. Ari 9 akapfuma gasi mapazi rakamiswa ichivhuvhuta makamuri jira kuwedzera majoini umo mhepo iri yaipiwa pasi kumanikidzwa yoga dzinoshandisa 3-4 kPa, mu dzakaonda gasi - 6 vachiridza makamuri pamwe yoga feni. Magasi yokuvanda vakanwa yoga mafeni zviviri kupa pokugara pasi Vacuum vanenge 20 kPa. Rich magasi 5-7% sarufa yakasviba inoendeswa kugadzirwa sulfuric acid. In haizoshandisi izvi 55-60% of nesarufa huri mutariri. Murombo magasi 2-2.5% sarufa yakasviba kana zvishandiswezve kuti kuridza munzvimbo yokutanga makamuri 9 (kushanda pamwe recirculation) kana pashure kutonhora kuti 450-500 ° C 80 ° C anotumwa kuti muguruva muunganidzwa bhegi filters uye asunungurwa mumhepo. We vachiridza agglomachines siyana raiva pedyo nebundu vesa mhosva. Ichivhuvhuta sintering Machine inopiwa vatatu inosimbisa hoppers nekuti mubhedha rukoko uye chinoumba incendiary vebasa. Kukwirira mubhedha rukoko iri 15-20 neMM, 20-25 mm incendiary rukoko nechigadziko paiva 200-250 mm. The mubhedha yakagadzirirwa kubvira achiparadzira agglomerate PARTICIPLE kukura 8-15 mm. Incendiary rukoko chinhu chiduku icho akaparadzaniswa mune ruzha asati rokukwidza mutariri kuti sinter beach. Incendiary nyanga uye zvinyama compensators vane gasi kana mafuta burners iri pakati feeder rukoko uye chinoumba incendiary vebasa. Akatungidza rukoko chichifamba pamwe Ribbon, vachisiya marongera huru vebasa. Under gomo iri chete Vacuum kamuri, sezvamakaropafadzwa Vacuum ndiyo 1-1.5 kPa. Dzakananga zvibereko agglomachines vachiridza Kuumbwa ndiyo 13-18 t / (m2sut). Murombo nesarufa yakasviba gasi sinter kunze kushandisa sezvo achiparadzira mu recirculating nematunhu vanogona pasi pashure nokubviswa guruva yoga kubudiswa, semuenzaniso, citrate nzira, sezvo rakatangwa muna kugadzwa kutungamirira US zvinomera. Gas (Figure 3.8.) Ko zvokudya kuna Absorção de Água mbiru ane kamwene uye kunoita countercurrently ine mhinduro pamusoro cucumber acid. The kunyatsoshanda kuti Absorção de Água rwesarufa yakasviba kuti cucumber asidhi ndiyo 96-99%. The mhinduro mushure Absorção de Água ikarapwa pamwe rehydrogen sulfide kune zvokuvamba nesarufa. Pulp pashure kupatsanurwa nesarufa iri pumped kuva kamuri chaiyo apo eparafini inowedzerwa sarufa flotation. The akapora sarufa yanyungudika uye akadurura kuva Kudzingwa uremu kg 45. Regenerated mhinduro kubva cucumber asidhi kubva flotation muchitokisi iri vakadzokera Absorção de Água mbiru. Inogona gasi ndiyo 2.8-4.2 m3 / Maminitsi gasi Sarufa - 816 makirogiramu / zuva.
