Description
Известные способы производства форстеритовых и периклазо-форстеритозых изделий ллавлением природных ;ма.пнезиальна-силикатных минералов (оливин, дунит, змеевик, тальк и т. п.), содержащих обычно довольно значительное количество (5-15%) окислов железа, не обеспечивают нужной тугоплавкости изделий .Known methods for the production of forsterite and periclase-forsteritic products for the fusion of natural; marsh-silicate minerals (olivine, dunite, serpentine, talc, etc.), containing usually quite a significant amount (5-15%) of iron oxides, do not provide the necessary refractoriness of products.
Олисываемый способ производства форстеритовых и периклазо-форстеритовых огнеупорных изделий путем плавлени таких природных магнезиальных силикатов отличаетс тем, что дл снижени содержани в издели х низкоплавких окислов железа и таким образом дл повышени тугоплавкости изделий к шихте добавл ют васстаиовители, напри.мер, кокси« , антрацит и т. п.The method of production of forsterite and periclase-forsterite refractory products by melting such natural magnesia silicates is characterized by the fact that to reduce the content of low-melting iron oxides in the product and thus to increase the refractoriness of the products, vasstani, for example, coxy, anhydrous, for example, co-powder and anhydrous, are added to the mixture. etc.
Опыты показали, что в плавленом изделии из дунита, содержащем около 12% РезОз, количество окислов железа при применении восстановител может быть снижено до 1-2%.Experiments have shown that in a dunite melted product containing about 12% ReZoz, the amount of iron oxides can be reduced to 1-2% when using a reducing agent.
Нар ду с окислами железа в процессе плавки восстанавливаетс частично также кремнезем, и получаетс ферросилиций с содержанием кремни до 10-16%.Along with iron oxides, the silica is also partially reduced during the smelting process, and ferrosilicon is obtained with a silicon content of up to 10-16%.
Литые плавленые огнезпор«ые издели форстеритового и лериклазофорстеритового типа могут найти широкой применение в ответственных част х кладки .мартеновских и. электросталеплавильных печах.Molded fused fire-resistant products of forsterite and lericlazoforsterite type can be widely used in the critical parts of the marten and. electric furnaces.
