A cikin 2015, mai ƙirƙira Cui Weihua ya bayyana alamar haƙƙin mallaka: hanya don shirya tsaftataccen tsaftataccen sinadarin calcium carbonate daga slag karfe. Shin zai yiwu a yi tsaftataccen calcium carbonate daga karfe slag ta amfani da? karfe slag nadi a tsaye?

A cewar cibiyar sadarwa ta fasahar foda ta kasar Sin, kwanan nan, an kaddamar da "100000 ton carbonization method iron and steel slag comprehensive utilization industryization show line", wani aikin da aka kulla na "sake sabunta Mongoliya ta hanyar kimiyya da fasaha", an kaddamar da shi a Baotou. Kamfanin Baotou Steel Group da Yukuang Environmental Protection Technology (Shanghai) Co., Ltd ne suka gina aikin tare. An ba da rahoton cewa aikin ya dogara ne akan sakamakon "layin tabbatar da ton 10,000 don cikakken amfani da shingen karfe ta hanyar carbonization". The karfe slag ne comprehensively carbonized, kuma a karshe samar da masana'antu ta-kayayyakin kamar high-tsarki alli carbonate da baƙin ƙarfe dauke da kayan, don gane da albarkatu sake amfani da karfe slag. Idan aka kwatanta da na gargajiya fasahar, da carbonization baƙin ƙarfe da karfe slag jiyya fasahar iya kai tsaye dauki carbon dioxide a matsayin albarkatun kasa don shiga cikin dauki yayin da rage watsi da carbon dioxide, wanda yana da dual carbon rage sakamako, cimma burin na rage greenhouse gas watsi da kuma inganta ci gaban da madauwari low-carbon. Bayan kammala aikin, 424000 ton na slag karfe za a iya bi a kowace shekara, yayin da game da 100000 ton na carbon dioxide za a iya samu carbonized (hatimi), da kuma samar da damar 200000 ton na high-tsarki calcium carbonate da 310000 ton na baƙin ƙarfe kayan za a iya cimma. Wannan aikin shine ƙarin binciken nunin masana'antu, wanda za'a iya inganta shi sosai a cikin kamfanoni iri ɗaya. Yayin biyan buƙatun cikakken amfani da ƙaƙƙarfan sharar gida, yana da amfani don cimma burin kololuwar carbon da kawar da carbon. Wannan yana nufin yuwuwar aikin samar da sinadarin calcium carbonate mai tsafta daga karfen karfe. Har ila yau, yana ba da sabuwar hanya don cikakken amfani da sharar gida na karfe slag.

Babban fasali na fasaha na samar da high-tsarki calcium carbonate daga karfe slag ne kamar haka: da farko, niƙa da karfe slag cikin foda, fallasa da free calcium oxide a cikin karfe slag zuwa saman da karfe slag, cire alli oxide a cikin karfe slag ta hanyar rigar 0.5% acetic acid, tace da kuma bayyana, sa'an nan carbonize shi da carbon sanyi gas, wanke, da kuma samar da busassun iskar gas, sa'an nan a wanke da kuma bushe bushe. high-tsarki haske calcium carbonate.

A cikin wannan tsari, niƙa fineness na karfe slag bukatar isa fiye da 400 meshes. Wani irin kayan aiki za a iya amfani da su don cimma babban sikelin samar da karfe slag micro foda? A matsayin ƙwararrun masana'anta nakarfeslag niƙa niƙa, HCMilling (Guilin Hongcheng) ya ba da shawarar cewa ka zaɓaHLM karfe slagnadi a tsaye domin samar da karfe slag foda.
