Изобретение относится к металлургии, конкретно к непрерывному литью заготовок из цветных металлов и сплавов. С целью повышения срока службы графитовых кристаллизаторов, повышения качества и снижения себестоимости непрерывнолитых заготовок предложен способ непрерывного литья заготовок из цветных металлов и сплавов, согласно которому поверхность жидкого металла в миксере, соединенном с горизонтальным графитовым кристаллизатором, покрывают графитом, преимущественно из отходов производства, со сродством (активностью) к кислороду не ниже сродства к кислороду графитового кристаллизатора, что повышает защитно-восстановительные свойства покрытия. В качестве покрытия можно использовать совместно или раздельно бой отработанных кристаллизаторов, электродные огарки, графитовую стружку, графит, нарезанный в виде плит, а также графит с нанесенными на него резьбой, пазами, выемками, развивающими активную поверхность, контактирующую с жидким металлом, и способствующими повышению реакционной способности покрытия. Сверху на защитно-восстановительное покрытие в миксер можно вводить теплоизоляционное покрытие.The invention relates to metallurgy, specifically to the continuous casting of non-ferrous metals and alloys. In order to increase the service life of graphite crystallizers, improve quality and reduce the cost of continuously cast billets, a method for continuous casting of non-ferrous metal and alloy billets has been proposed, according to which the surface of a liquid metal in a mixer connected to a horizontal graphite crystallizer is coated with graphite, mainly from production waste, with affinity (activity) to oxygen is not lower than the affinity to oxygen of a graphite crystallizer, which increases the protective and restorative properties of the coated and I. As a coating, you can use together or separately the fight of spent molds, electrode cinders, graphite chips, graphite, cut into slabs, as well as graphite with threads, grooves, grooves applied on it, which develop an active surface that comes in contact with the liquid metal and contributes to reactivity of the coating. On top of the protective-reducing coating in the mixer, you can enter the insulating coating.
