Description

Известные смеси дл  изготовлешг  лите&иых стержней с неорга1ническими св зующими имеют недостаточно хорошую выбиваемость. что снижает производительность труда is обрубных отделени х литейных цехов.Known mixtures for the fabrication of casting rods with inorganic binders have insufficiently good knockability. which reduces the productivity of labor is the chaff branches of foundries.

В предлагаемой смеси этот недостаток устранен тем, что в состав смесей ввод т компоненты, образующие двойную, тройную или четверную системы, как например: окись алюмини , глину и др., в которых температура образовани  жидкой фазы превышает температуру прогрева стержн  при заполнении формы металлом. Такие смеси улучшают выбиваемость стержней из оТоТивок.In the proposed mixture, this disadvantage is eliminated by the fact that components that form a double, triple or quadruple system, such as alumina, clay, etc., are introduced into the mixture, in which the temperature of formation of the liquid phase exceeds the heating temperature of the rod when the form is filled with metal. Such mixtures improve the knockout of the rods from the coolants.

Смеси составл ютс  на основе тройных или четверных систем, причем в качестве третьего или четвертого компонента выби-раетс  любой из тех, который обеспечивает надлежащее передвижение вправо по оси абсцисс точки, отвечающей максимальной работе, затрачиваемой на выбивку стержн . Таким компонентом может служить окись алюмини  или глина, содержаща  соответствуюи1.ее количество окиси алюмини , окиси кальци  или окиси магни . Во всех случа х применени  указанных смесей резко расшир етс  зона, обеспечивающа  совершенно свободную выбивку стержн  из от.тивок, а также снижаетс  величина работы, необходимой на выбивку стержней.The mixtures are based on triple or quadruple systems, with the third or fourth component choosing any of those that provide proper movement to the right along the abscissa axis of the point corresponding to the maximum work expended on knocking the rod. Such a component can be alumina or clay containing the corresponding amount of alumina, calcium oxide or magnesia. In all cases of the use of these mixtures, the zone drastically expands, ensuring a completely free knockout of the rod from the valve, and also reduces the amount of work required for knocking the rods.
