Vata metallurgy samarwa

Daya daga cikin manyan sassa na tattalin arziki ne metallurgy. Yana samar da albarkatun kasa, da yawa wasu masana'antu. Ferrous da kuma wadanda ba ferrous karafa da ake bukata kusan ko'ina. Kuma farashin wadannan albarkatun kasa na kara kowace rana. Energy farashin, ba shakka, da wani gagarumin sakamako a kan farashin karfe kayayyakin. Amma muhimmiyar rawa a cikin samuwar da kuma samar da sharar gida taka farashin.

Kuma a cikin metallurgy na musamman manyan. Sun riga sun mamaye manyan yankunan da haka sama da iska mai guba mahadi, ruwa da kuma ƙasa. Kuma a lokaci guda a kan su masauki halin kaka, ajiya da kuma harkokin sufuri da wani gagarumin tasiri a kan kudin samarwa na metallurgical Enterprises. Amma wadannan abinci dauke da wani yawa na abubuwa da cewa za a iya amfani da a matsayin na biyu raw kayan. Kuma a lokacin da maigidansa m, irin metallurgical tõzarta za a iya juya a cikin wani tushen samun kudin shiga.

Wadannan tõzarta haifar daga cikin smelting na karfe, jefa baƙin ƙarfe ko ferroalloys. Kuma abun ciki na daban-daban ma'adinai aka gyara, wanda zai iya hada baƙin ƙarfe, yana iya zama ma fi a su fiye da a cikin wannan halitta ores. Kuma saboda da kasa nazarin tsarin da kuma kaddarorin sludges akwai matsala tare da su sake amfani.

Samun a kalla da steelmaking slag. Wadannan recyclable sharar samarwa a da yawa karfe Mills da kuma masana'antu tuba a cikin wadãtar slag. A saboda wannan dalili da "bushe" Magnetic rabuwa kayayyakin samu bayan crushing na slag. A amfani samfurin samu bayan wannan magani, jini lemu dauke fi girma karfe da kuma aggregates na karfe da kuma silica gilashi. Iron-wadãtar slag abun da ke ciki shi ne in mun gwada kadan. Kuma a sakamakon enrichment a sinter shuke-shuke da ton na slag samar game da 40 kg na karfe. Sauran sharar kayayyakin, wanda dauke da kawai kananan blotches ko kuwa baƙin ƙarfe oxide an ciyar a cikin ruwa.

Amma akwai wani da ya fi dacewa da fasaha ga enrichment na karfe slag. Da taimakon wadannan wastes iya samun uku kayayyakin. Na farko shi ne wani karfe samfurin. Yana zai zama game da 10% na slag taro. Shi ne, kuma ƙarfe baƙin ƙarfe, ya ƙunshi qananan impurities gilashi, silicates da carbonates. Ya briquetted da kuma aika zuwa secondary smelter. Na biyu shi ne lemun tsami-baƙin ƙarfe oxide samfurin. Shi ne game da 22% na jimlar. Iron a cikin wannan samfurin kadan. Domin mafi part, shi kunshi daban-daban ma'adanai. Wannan wustite, magnetite, maghemit, goethite, hematite, hydrated lemun tsami, da baƙin ƙarfe da alli carbonates, kazalika da magnesium da alli ferrites. Wannan samfurin za a iya amfani da a matsayin high quality feed abu a samar da baƙin ƙarfe sinter fluxed. Kuma da saura, wanda shi ne game da 68% da dama a kan silica samfurin. Its main kashi kunshi ma'adanai: silicates, spinels, tridymite, silicate gilashin da lemun tsami hydration kayayyakin. Wadannan sharar kayayyakin ma ba a banza. Silicate samfurin da aka yi amfani da yafi a yi, ciminti ko wasu cementitious kayayyakin.

Zaka kuma iya daukar wani slag ferromanganese samar, wanda dauke da yawa m aka gyara. Wannan jini lemu ferromanganese da kuma ƙarfe baƙin ƙarfe, silicates, hydroxides, oxides aggregates, manganese da na baƙin ƙarfe carbonates, silicate gilashi, da kuma kayayyakin da ta crystallization. Masana kimiyya sun ɓullo da wani tsari ne da abin da hali bushe nauyi taro na wadannan gubobi. A sakamakon wadannan sharar kayayyakin taimaka wajen samar da uku kayayyakin.

A farko daga cikin wadannan ne baƙin ƙarfe manganese tattara. Daga cikin jimlar taro na slag shi iya samun up to 17%. Wannan samfurin ƙunshi Magnetic da kuma wadanda ba Magnetic sassa na baƙin ƙarfe, manganese, Cohen baƙin ƙarfe da daban-daban gami da sãɓãwar launukansa abinda ke ciki na manganese da baƙin ƙarfe, da kuma su oxides da hydroxides. Amfani da wannan samfurin iya zama domin samar da ferromanganese.

Na biyu samfurin ne a silicate yashi. Rabin na jimlar slag nauyi da dama a kan shi. Silicate yashi kunshi yafi na ma'adini, cristobalite, tridymite, gilashin da silicates. Daga shi ba za ka iya sarrafa silicomanganese ko amfani da shi a matsayin wani gini abu.

Sauran 33% zo daga lãka-carbonate ƙura. Yana da aka hada da finely raba silicates, carbonates, gilashin da sauran ma'adanai. Wannan kura da ake amfani da ciminti samar. Akwai su da yawa fiye da na da irin wannan sharar gida, wanda zai iya amfana mutane.
