Description
турьа. рри этом степень использовани циркони возрастает до 96-98%.turya In this case, the degree of use of zirconium increases to 96-98%.
Цель изобретени достигаетс тем, что плавку ведут в две стадии. На первой стадии производ т алюминотермическое восстановление окислов Т1игкони и железа с получением циркониевого корунд и его слив. На второй стадии на оставшийс в печи металл ввод т металлодобавки-ферросилиций, силикомарганец и отходы титана в количестве 53-101% от цирконового концентрата и получают модификаторы.The purpose of the invention is achieved by melting in two stages. In the first stage, the aluminothermic reduction of Tigonium oxides and iron oxides is carried out to produce zirconium corundum and its discharge. In the second stage, metal additives-ferrosilicon, silico-manganese and titanium waste in the amount of 53-101% of zircon concentrate are added to the remaining metal in the furnace, and modifiers are obtained.
Вместо циркониевого корунда возможно получение полупродукта - сырь дл выплавки ферроалюминоциркони . В насто щее врем сырье дл получе-i ни ферроалюминоциркони служит дорогосто ща техническа двуокись циркони . С целью получени полупродукта Примеры осуществлени способа.Instead of zirconium corundum, it is possible to obtain an intermediate product - a raw material for smelting ferroaluminocirconium. At present, raw zirconia is a raw material for obtaining neither ferroaluminocirconium and zirconia. In order to obtain a semi-product Examples of the method.
из цирконового концентрата в первой стадии плавки за 5-15 мин до ее окончани на расплав ввод т известь в количестве 20-30% от цирконового концентрата и его сливают, а на оставшийс в печи металл ввод т метгиплодобавки .from the zircon concentrate in the first stage of melting, 5–15 minutes before its completion, lime in the amount of 20–30% of the zircon concentrate is introduced into the melt, and it is poured, and the additives in the remaining metal in the furnace are introduced.
Опытные плавки провод т в лабораторной дуговой печи мощностью 60 квт. Примеры осуществлени способа приведены в табл.Experimental melting is carried out in a 60 kW laboratory arc furnace. Examples of the method are given in table.
Выплавленные описываемым способом модификатора и циркониевый корунд удовлетвор ют Техническим Услови м на готовую продукцию, соответственно ТУ 14-5-46-74 и ТУ 14-5-47-74-.The modifier and zirconium corundum smelted by the described method satisfy the technical specifications for finished products, respectively TU 14-5-46-74 and TU 14-5-47-74-.
Степень использовани цирконий при выплавки модификаторов по за вленному способу возрасла до 97,2-97,9% против 88,1%The degree of use of zirconium in the smelting of modifiers according to the claimed method increased to 97.2-97.9% against 88.1%
