Изобретение относится к черной металлургии, в частности к теплоизолирующим смесям, применяемым при разливке спокойной стали. Предложена тeплоизолирующая смесь, содержащая пыль газоочисток производства ферросилиция. Отличие смеси заключается в том, что смесь дополнительно содержит технический углерод или технический углерод в сочетании с аморфным графитом или/и с молотым коксиком, или/и с молотым углем, или /и с молотым боем графитовых электродов при следующем соотношении ингредиентов, об.%: пыль газоочисток производства ферросилиция 60 - 95; технический углерод или технический углерод в сочетании с аморфным графитом или/и с молотым коксиком или/и с молотым углем или/и с молотым боем графитовых электродов 5-40. Предложенная теплоизолирующая смесь позволяет получить новый технический результат, заключающийся в улучшении качества поверхности и макроструктуры слитка.The invention relates to ferrous metallurgy, in particular to insulating mixtures used in the casting of mild steel. A heat-insulating mixture containing dust of gas purification from the production of ferrosilicon is proposed. The difference of the mixture is that the mixture additionally contains carbon black or carbon black in combination with amorphous graphite and / or with ground coke, or / and with ground coal, and / or with ground battle of graphite electrodes in the following ratio of ingredients, vol.% : dust gas purification production of ferrosilicon 60 - 95; carbon black or carbon black in combination with amorphous graphite and / or with ground coke and / or with ground coal and / or with ground battle of graphite electrodes 5-40. The proposed heat-insulating mixture allows to obtain a new technical result, which consists in improving the surface quality and macrostructure of the ingot.
