APPARATUS FOR THE ANALYSIS OF NON-FERROUS METAL ALLOYS AND PARTICULARLY FOR 'S.T.A.' TYPE ANALYSES, A SYSTEM FOR THE QUALITY CONTROL OF LIGHT ALLOYS COMPRISING SUCH APPARATUS AND A METHOD OF OPERATION OF SUCH APPARATUS

摘要

The present invention relates to an apparatus (10) for the analysis of non- ferrous metal alloys, particularly for 'S.T.A.' type analyses, comprising: - a solidification cup (11) inside which a containment compartment (12), intended to accommodate a metallic material in the molten state, is defined; - heating means (13), for heating the solidification cup (11); - cooling means (14) for cooling the solidification cup (11 ); - a protection ferrule (15), protruding inside said containment compartment (12), configured to accommodate and cover the end of a thermocouple; - a central thermocouple (16), inserted into a through-hole (17) at the bottom (11a) of the solidification cup (11), with the end positioned in said protection ferrule (15); - ejection means (19) configured to permit the ejection of a body of solidified metallic material from the containment compartment (12); - a thermocouple of the cup (24) for measuring the temperature of the solidification cup (11); - an electronic control unit (150) configured to switch on and off said heating means (13) and said cooling means (14), and to receive and transmit signals from said central thermocouple (16) and from said thermocouple of the cup (24).
