Изобретение относитс  к составам керамических масс дл  изготовлени  стержней литых изделий со сложной конфигурацией внутренней полости, преимущественно турбинных лопаток авиационных газотурбинных двигателей .The invention relates to compositions of ceramic masses for the manufacture of cores of molded products with a complex configuration of the internal cavity, mainly turbine blades of aircraft gas turbine engines.

Цель изобретени  - снижение температуры прокалки стержней.The purpose of the invention is to reduce the temperature of roasting rods.

Это достигаетс  тем, что в стержневую массу на основе пылевидного кварца, электрокорунда и пластификатора совместно введены окись гадолини  и материал, содержащий соединени  натри , а именно сода, при следующем соотношении компонентов, вес. %: Пылевидный кварц65-70This is achieved by the fact that gadolinium oxide and a material containing sodium compounds, namely soda, are added to the rod mass based on powdered quartz, electrocorundum and plasticizer. %: Dusty quartz65-70

кой массы (кроме пластификатора), примен ют в виде измельченных порошков. Пластификатор ПП-15 ввод т в предварительно перемешанную и подогретую навеску порошкообразных компонентов в виде расплава при 120-130°С дл  пластифицировани  массы.This mass (except plasticizer) is used in the form of powdered powders. Plasticizer PP-15 is introduced into a pre-mixed and heated sample of powdered components in the form of a melt at 120-130 ° C to plasticize the mass.

Прокалку изготовленных стержней производ т при 950°С (продолжительность процесса прокалки 40-50 :ac) в коробках, с засыпкой стабилизированным глиноземом.The roasting of the manufactured rods is carried out at 950 ° C (the duration of the calcination process is 40-50: ac) in boxes, filled with stabilized alumina.
