Description
Предметом изобретени вл етс обработка чугуна лкимие.м дл получени сфероидальной формы гра ()ита.The subject of the invention is the treatment of cast iron with lmii.m to obtain a spheroidal gra () ita.
При вводе в чугун чистого твердого магни или его лнгатуры с железом и.чи кремиием осваиваетс только до от введеиного машн , и расход его очень всл1п. Кроме того, развиваюнсинс при этом значительный пиротехнический эффект весьма затрудн ет работу.With the introduction of pure solid magnesium or iron with iron and chi cremium into the cast iron, it is mastered only up to the introduction of the machine, and its consumption is very high. In addition, the development of a significant pyrotechnic effect in this case makes work very difficult.
Особенность оиисьн аемого способа состоит в предварительном окислеи1П1 чугуна и раскислении его иос.те обработки магнием.The peculiarity of this method consists in the preliminary oxidation of pig iron and deoxidation of its ion treatment with magnesium.
(Содержание кислорода в жидком чугуне, т. е. в окис.лах железа (FcO ), недостаточно дл сжнганп магпи ; это вл етс средством ctniженн расхода магни . Предварительное окисление жидкого чугуна увеличивает содержание кислорода в нем и обесиечивает сгорание вводимого магип в окись маг}иш по реакции FcO - Mg-Fc MgO -Q(The oxygen content in liquid iron, i.e., in iron oxides (FcO)) is not enough for gas; it is a means of reduced magnesium consumption. Pre-oxidation of liquid iron increases the oxygen content in it and depletes the combustion of the injected oxide into the mag } ish by the reaction of FcO - Mg-Fc MgO -Q

No. 95348 The subject matter of the invention is 1. A method for producing pig iron with its spheroidal form of graft by introducing magnesium, so that liquid iron is pre-oxidized to form refractory centers of crystallization in the form of particles of magnesium oxide, in order to intensify the formation of spheroidal particles of graft, but one of the cast iron is deoxidized. 2.lipMeM Implementation of the method UO p. 1, - that is, with what, for the oxidation of cast iron used forge scale. 3. Acceptance of the method of PP. 1 and 2, characterized in that blacksmith dross is introduced into the molten iron in a furnace or ladle. 4. Acceptance of the sioosob according to claim 1, characterized in that the cast iron after treatment with magnesium is reduced by ferrosilicon.
