Description
Изобретение относитс к области черной металлургии, в частности к производству ферросплавов.The invention relates to the field of ferrous metallurgy, in particular to the production of ferroalloys.
Известен способ дефосфорашш марганцевых ферросплавов, основанный на обработке расплава в ковше перед разливкой дефосфорирующим реагентом, например углекислым натрием в смеси с сернокислым натрием. Недостатками этого способа вл ютс дефицитность предложенных реагентов и большие потери марганца вследствие его окислени l.The known method of dephosphoric manganese ferroalloys, based on the processing of the melt in the ladle before pouring the dephosphorizing reagent, such as sodium carbonate in a mixture with sodium sulfate. The disadvantages of this method are the deficiency of the proposed reagents and the large losses of manganese due to its oxidation.
Цель изобретени - снижение содержани фосфора в силикомарганце в.жидком состо ниии устранение указанных недостатков.The purpose of the invention is to reduce the phosphorus content in silicomanganese in the liquid state and to eliminate these drawbacks.
Поставленна цель достигаетс путем присадки стандартного силикокальии 20-25 кг/т сплава в разогретый ковш с последующим переливом к нег-о жидкого сипнкомарганца после скачивани шлака.The goal is achieved by adding a standard silicocalcium of 20-25 kg / ton of alloy into a heated ladle, followed by overflow to a neg-liquid manganese syrup after slag loading.
Пример, После вь.птуска сппава из печи в ковш произвошгтс скачиваниеExample, After spinning from the furnace into the ladle, download
шлака, а затем жидкий силикомарганец переливаетс в разогретый ковш от предыдушей плавки, куда предварительно присаживаетс стандартный силикомарганец в количестве 2О-25- кг/т сплава. Разливка силикомарганца после обработки сипи- кокальцием производитс по обычной технологии .slag, and then liquid silico-manganese is poured into the heated ladle from the previous melt, where the standard silico-manganese in the amount of 20-25 kg / ton of alloy is previously set. The casting of silicomanganese after treatment with dipocalous calcium is carried out according to the usual technology.
При присадке силикокальци растворенный в сплаве фосфор взаимодействует с кальцием с образованием термодинамически прочных тугоплавких и имеюших малый удельный вес фосфидов по реакции.With the addition of silicocalcium, the phosphorus dissolved in the alloy reacts with calcium to form thermodynamically strong refractory and having a small proportion of phosphides by reaction.
