SINTERING MATERIAL GRANULATION METHOD USING X-RAY CT

Title:

SINTERING MATERIAL GRANULATION METHOD USING X-RAY CT

Document Type and Number:

WIPO Patent Application WO/2010/073718

Kind Code:

A1

Abstract:

A sintering material granulation method using X-ray CT comprises a granulation step, in which water is added and sintering material is granulated; a granulated material measurement step, in which the weight (M) of the granulated material is measured, and the volume (V) of the granulated material is found from a CT sectional image; a dried material measurement step, in which, after the granulated material measurement step, the granulated material is dried and the weight (m) of the dried granulated material and the true density (ρ0) of the dried granulated material are measured; and a water adjustment step, in which the water saturation (S) is found from the weight (M), the volume (V), the weight (m), and the true density (ρ0), and then the quantity of the water to be added to the sintering material is adjusted so that this water saturation (S) is not less than 0.9 and not more than 1.05.
