Description

1one

Изобретение относитс  к рафинированию чугуна, в частности к его десульфурации.The invention relates to the refining of cast iron, in particular to its desulfurization.

Известен способ пассивации магни , заключающийс  в его разубоживании наполнителем, например, доломитизированным известн ком. Однако известные способы не обеспечивают низкой скорости испарени  магни  в чугуне и высокой степени его усвоени .There is a method of passivating magnesium, which consists in its dilution with a filler, for example, dolomitic limestone. However, the known methods do not provide a low rate of evaporation of magnesium in the cast iron and a high degree of its absorption.

С целью увеличени  степени использовани  магни , снижени  пироэффекта при десульфурации и увеличени  степени десульфурацин по предложенному способу расплав магни  заливают на кусковой наполнитель, предварительно нагретый до 600-650° С. Причем, магний заливают в количестве 40-60% от веса исходных материалов, а в качестве наполнител  используют легирующие элементы.In order to increase the use of magnesium, reduce the pyroelectric effect during desulfurization and increase the degree of desulfuracin according to the proposed method, the molten magnesium is poured onto the lump filler preheated to 600-650 ° C. Moreover, magnesium is poured in the amount of 40-60% by weight of the starting materials, and alloying elements are used as filler.

Кусковой наполнитель, нагретый до 600- 650° С и помещенный в изложницу, заливают расплавом магни , охлаждают и подают дл  обработки чугуна.The piece filler, heated to 600–650 ° C and placed in a mold, is poured with magnesium melt, cooled, and iron is fed for processing.

Магний в процессе заливки заполн ет неплотности и пустоты между кусками наполнител .Magnesium in the process of pouring fills leaks and voids between the pieces of filler.

В качестве пассиватора может использоватьс  щлак металлургического производства, кокс и другие элементы, а также легирующие элементы.Slag of metallurgical production, coke and other elements, as well as alloying elements can be used as passivator.

Claims (3)

1.Способ пассивации магни  разубоживанием его наполнителем, отличающийс  тем, что, с целью увеличени  степени использовани  магни , снижени  пироэффекта при десульфурации и увеличени  степени десульфурацин, расплав магни  заливают на кусковой наполнитель, предварительно нагретый до 6вО-650° С.1. A method for passivating magnesium by diluting it with a filler, characterized in that, in order to increase magnesium utilization, decrease the pyroeffect during desulfurization and increase desulfuracin, the magnesium melt is poured onto a lumpy filler preheated to 6 ° C-650 ° C. 2.Способ по п. 1, отличающийс  тем, что магний заливают в количестве 40-60% от веса исходных материалов.2. A method according to claim 1, characterized in that the magnesium is poured in an amount of 40-60% by weight of the starting materials. 3.Способ по МП. 1 и 2, отличающиЛс  тем, что и качестве наполнител  используют ле1ирующие элементы.3. Method of MP. 1 and 2, characterized in that the quality of the filler is based on the use of the elements.
