Изобретение относитс к литью металлов и сплавов, в частности к полунепрерывному и непрерывному литью алюмини и его сплавов.The invention relates to the casting of metals and alloys, in particular to the semi-continuous and continuous casting of aluminum and its alloys.
При полунепрерывном и непрерывном литье слитков рабоча поверхность кристаллизаторов покрываетс слоем защитно-смазывающей смеси. Основное назначение таких смазок - обеспечить получение гладкой и ровной поверхнос-,о ти слитка.In semicontinuous and continuous casting of ingots, the working surface of the molds is covered with a layer of protective lubricant. The main purpose of such lubricants is to ensure a smooth and even surface, about the ingot.
Известна защитно-смазывающа смесь дл непрерывного лить слитков из алюмини , состо ща из смеси вапора и.олеиновой кислоты в соотношении 15 70:30, получаема путем тщательного перемеи1ивани составл ющих компонентов lj.The known protective lubricating mixture for continuous casting of aluminum ingots, consisting of a mixture of vapor and oleic acid in a ratio of 15 to 70:30, is obtained by carefully mixing the components lj.
К недостаткам данной защитно-смазывающей смеси относитс : то, что дл 20 обеспечени процесса лить необходимо наносить смесь на рабочую поверхность кристаллизатора через каждыеThe disadvantages of this protective lubricating mixture include: that in order to ensure the process of the casting, it is necessary to apply the mixture to the working surface of the crystallizer every
200-300 мм длины слитка. В результате имеет место значительный расход смазки , а также загр знение атмосферы цеха газами, образующимис при сгорании смазки.200-300 mm ingot length. As a result, there is a significant consumption of lubricant, as well as pollution of the atmosphere of the workshop with gases generated during the combustion of lubricant.
Наиболее близким к предлагаемому вл етс способ приготовлени защитно-смазывающей смеси дл непрерывно-, го лить слитков из алюмини и его сплавов, включающий перемешивание вапора и олеиновой кислоты с алюминиевой пудрой, которую получают методом сухого размола алюминиевого порошка в пудру. Данную защитно-смазывающую смесь получают путем тщательного перемешивани смеси вапора и Олеиновой кислоты с алюминиевой пудрой , которую предварительно получают методом сухого размола алюминиевого по.рошка в пудру. Сухой размол алюминиевого порошка осуществл ют в присутствии повсрхностноактивных псщсста, например, стеарина (стеариногзой кисClosest to the present invention, there is a method for preparing a protective lubricating mixture for continuous casting ingots of aluminum and its alloys, including mixing a vapor and oleic acid with aluminum powder, which is obtained by dry grinding of aluminum powder into powder. This protective lubricating mixture is obtained by thoroughly mixing a mixture of vapor and oleic acid with aluminum powder, which is previously prepared by dry grinding aluminum powder into powder. Dry milling of aluminum powder is carried out in the presence of highly active agents, for example, stearin (stearic acid
