Kupanga zitsulo zinyalala

Mmodzi mwa zigawo zikuluzikulu za chuma ndi zitsulo. Amatipatsa zopangira, zina zambiri mafakitale. Ferrous ndi zitsulo sanali akakhala zofunika kulikonse. Ndi mitengo ya zipangizo zopangira ndi kuwonjezeka tsiku ndi tsiku. mitengo mphamvu, ndithudi, ndi zotsatira kwambiri pa mtengo wa katundu zitsulo. Koma yofunika kwambiri mu mapangidwe ndi kupanga zinyalala masewero mitengo.

Ndipo mu zitsulo awo makamaka lalikulu. Iwo amakhala m'madera ambiri chotero kuipitsanso mpweya poizoni mankhwala, madzi ndi nthaka. Ndipo pa nthawi yomweyo pa malawi ndalama zawo, yosungirako ndi mayendedwe a kukopa kwambiri pa mitengo ya zinthu amakampani zitsulo. Koma zakudya zimenezi zimakhala zambiri zinthu zimene zingagwiritsidwe ntchito ngati zipangizo sekondale yaiwisi. Ndipo pamene njira Ambuye, ngati zinyansi zitsulo akhoza lidzasanduka yopezera ndalama.

zinyansi izi n'chiyani pa yadothi cha chitsulo, chitsulo kuponyedwa kapena ferroalloys. Ndipo zili mwa zigawo zosiyana mchere, amene akhoza monga chitsulo, angakhale ochuluka kuposa kuposa mofanana ores achilengedwe. Ndipo chifukwa kuphunzira osakwanira ya kapangidwe ndi katundu wa sludges pali vuto ndi zingagwiritsidwenso ntchito zawo.

Pezani osachepera steelmaking slag. Izi recyclable zinyalala kupanga mu mphero ambiri zitsulo ndi mafakitale n'kukhala Polemeretsedwa slag. Chifukwa chaichi, "youma" maginito katundu kulekana analandira pambuyo kotheratu kwa slag lapansi. A mankhwala othandiza analandira pambuyo mankhwala, malalanje magazi ankaona zikuluzikulu zitsulo ndi aggregates wa zitsulo ndi galasi silika. Iron wabwino slag zikuchokera ndi zochepa. Ndipo chifukwa cha patsogolo pa zomera sinter wa matani slag opangidwa 40 makilogalamu zitsulo. Otsala muli, amene ali akagwidwa ndi zikanga chabe kapena chitsulo okusayidi zimalowa tsamba.

Koma pali luso zosavuta kwa patsogolo kwa slag zitsulo. Mothandizidwa ndi zinyansi awa akhoza kupeza mankhwala atatu. Woyamba ndi mankhwala zitsulo. Zingakhale pafupifupi 10% ya slag misa. Ndi kusiya zachitsulo chitsulo, muli zosafunika zazing'ono galasi, silicates ndi carbonates. Wake briquetted ndipo anatumizidwa ku ng'anjo sekondale. The chachiwiri ndi laimu zitsulo okusayidi mankhwala. Ndi 22% wa chonse pamodzi. Chitsulo mankhwala pang'ono. Nthawi zambiri, tichipeza mchere zosiyanasiyana. Izi wustite, magnetite, maghemit, goethite, hematite, hydrated laimu, chitsulo ndi calcium carbonates, komanso magnesium ndi kashiamu ferrites. mankhwala angagwiritsidwe ntchito ngati mkulu khalidwe chakudya nkhani yopanga sinter chitsulo fluxed. Ndipo otsala, ndiwo za 68% imagwera pa mankhwala silika. mbali yake yaikulu imakhala mchere: silicates, spinels, tridymite, silicate galasi ndi mankhwala laimu hydration. muli iwonso sikuli chabe. mankhwala silicate ntchito makamaka zomangamanga, simenti kapena mankhwala ena cementitious.

Mukhozanso kutenga kupanga slag ferromanganese, amene ali zigawo zambiri zamtengo wapatali. Izi malalanje magazi ferromanganese ndi zachitsulo chitsulo, silicates, hydroxides, oxides aggregates, manganese ndi carbonates chitsulo, silicate magalasi, ndi malonda a crystallization ake. Asayansi atulukira njira ina imene khalidwe youma yokoka ndende ya poizoni izi. Chifukwa cha mankhwala zinyalala athe kupanga mankhwala atatu.

Choyamba mwa zinthuzi ndi chitsulo manganese maganizo. Ya misa okwana slag angathe kutenga 17%. mankhwala lili mbali maginito ndipo sanali maginito ya chitsulo, manganese, Cohen chitsulo ndi kasakaniza wazitsulo zosiyanasiyana yosiyana nkhani za manganese ndi chitsulo, ndi oxides awo ndi hydroxides. Gwiritsani ntchito mankhwala Zimenezi zingakhale kwa kupanga ferromanganese.

The mankhwala yachiwiri ndi mchenga silicate. Theka la okwana slag kulemera imagwera pa iye. Silicate mchenga Amakhala makamaka wa khwatsi, cristobalite, tridymite, galasi ndi silicates. Kuyambira inu zingabweretse silicomanganese kapena ntchito monga chuma nyumba.

Otsala 33% amachokera ku fumbi dongo-carbonate. Iwo wapangidwa ndi silicates finely wogawanika, carbonates, galasi ndi mchere. fumbi ili ntchito yopanga simenti. Pali ambiri a mtundu umenewu zinyalala zomwe angapindule anthu.
