Изобретение относитс к области литейногоThis invention relates to the field of foundry.
производства, в частности к составам смесей.production, in particular to the compositions of mixtures.
Известна смесь дл литейных стержней иKnown mixture for foundry rods and
форм, состо ща из цирконового порошка иforms consisting of zircon powder and
алюмофосфата.aluminophosphate.
Однако эта смесь недостаточно прочна при высоких температурах.However, this mixture is not strong enough at high temperatures.
С целью устранени этого недостатка в состав смеси предложено вводить окись магни и сподумен при следующем соотношении компонентов (в вес. %):In order to eliminate this drawback, it was proposed to introduce magnesium oxide and spodumen in the composition of the mixture in the following ratio of components (in wt.%):
Цирконовый порошок Основа Алюмофосфат1,6-1,24Zircon Powder Base Alum Phosphate1,6-1,24
Окись магни 0,1-0,6Magnesium oxide 0.1-0.6
Сподумен0,8-1,0Spodumene 0.8-1.0
Дл получени высоких физико-механических свойств смеси цирконовый порошок желательно использовать следующего гранулометрического состава (в вес. %):To obtain high physicomechanical properties of the mixture of zircon powder, it is desirable to use the following particle size distribution (in weight%):
до 20 мк40up to 20 μ40
20-301620-3016
14 3014 30
30-40 40-6030-40 40-60
При температуре 1300°С стандартные образцы имеют прочность на сжатие 240 кГ/см, 5 а при 1450°С-390 кПсм.At a temperature of 1300 ° C, standard samples have a compressive strength of 240 kg / cm, 5 and at 1450 ° С-390 кПсм.
