MELTED MODEL COMPOSITION CLEANING METHOD AND INSTALLATION Russian patent published in 2018 - IPC B22C9/04 B22C5/00 

FIELD: technological processes.

SUBSTANCE: invention relates to metallurgy. Melted model composition is supplied to the settler hopper. Mechanical impurities are heated and removed by filtration. At that, controlling the melted model composition temperature in the settler hopper and enable the settler hopper oil jacket heating control. Controlling the model composition level. Performing the rough cleaning and dehydration. Transferring the dehydrated model composition from the settler hopper to the fine cleaning vacuum filter receiving container. Holding the melted model composition on the sheet filter in the fine cleaning vacuum filter receiving container. Dehydrated model composition vacuum filtration is performed through the sheet filter with porosity of no more than 30 mcm and final dehydration in fine cleaning vacuum filter vacuum container. Purified model composition is poured into molds and cooled down.

EFFECT: enabling improvement in the composition quality and the model composition use factor.
