(54)СМЕСЬ ДЛЯ ИЗГОТОВЛЕНИЯ(54) MIXTURE FOR MANUFACTURING

ЛИТЕЙНЫХ КЕРА(ШЧЕСКИХ ФОРМ И СТЕРЛШЕЙFOUNDRY KERA (SCALE FORMS AND STERLSHI)

экономически нецелесообразно. .Введение ж в смесь порошков металлов менее 0,5% недостаточно дл  улучшени  поверхности отливок по сравнению с известными сйес ми.economically impractical. . The introduction of oil into the mixture of metal powders of less than 0.5% is not enough to improve the surface of the castings as compared to known processes.

Химическа  инертность форм достигаетс  обжигом их при температуре 950105О С , при этом порошки металлов, содержащиес  в смеси, окисл ютс  газами атмосферы печи и газами, заключенными в порах формы. Так как процессы окислени  сопровождаютс  увеличениемChemical inertness of the forms is achieved by burning them at a temperature of 950105 ° C, while the metal powders contained in the mixture are oxidized by the gases of the furnace atmosphere and gases enclosed in the pores of the mold. Since the oxidation processes are accompanied by an increase in

объема образующихс  окислов по сравнению с исходным металлом, то одновременно с уменьшением количества газов в порах формы также и уменьшаетс  и ее пористость.the volume of oxides formed in comparison with the initial metal, then simultaneously with a decrease in the amount of gases in the pores of the mold, its porosity also decreases.

Примеры составов смесей, их прочность по-сухому и по-сырому и составление поверхности опытных отливок приведены в таблице.Examples of the composition of the mixtures, their strength dry and wet and surface preparation of the experimental castings are given in the table.

Смесь предназначена предпочтительно дл  получени  отливок из титановых сплавов .The mixture is preferably designed to produce titanium alloy castings.
