Description
кускового материала, что видно из следующих выше температуры его плавлени ):bulk material, as can be seen from the following above its melting point):
40-6040-60
Фракци наполнител , ммFraction filler mm
Оптимальна температура подогрева 300-350 наполнител , СOptimum temperature of heating 300-350 filler, C
По предложенному способу осуществл ют перегрев расплавленного магни , например до температуры 900°С. Расплавленный магний выливают в изложницы, заполненные кусковым наполнителем (например обожженным доломитом) фракции 20-40 мм, нагретым до температуры 150°С. После затвердевани слитки пасснвированного магни удал ют из изложниц и используют дл обработки жидкого металла . При перегреве магни на 150°С выше точки его плавлени , температура подогрева кускового наполнител должна быть не менее ЗОр°С.According to the proposed method, the molten magnesium is overheated, for example, to a temperature of 900 ° C. Molten magnesium is poured into molds filled with lump filler (for example, calcined dolomite) of a fraction of 20-40 mm heated to a temperature of 150 ° C. After solidification, the ingested magnesium ingots are removed from the molds and used to treat the liquid metal. When magnesium is overheated by 150 ° C above its melting point, the temperature of heating of the bulk filler should be at least ZOR ° C.
Предложенный снособ дает возможность улучшить распределение магни в межкусковых пустотах наполнител и повыситьThe proposed method provides an opportunity to improve the distribution of magnesium in the intercellular cavities of the filler and increase
