PURPOSE:To measure the heat retained by a substance fused at high temperatures with safety by a method wherein the fused specimen is placed in a specimen tank and the rise of temperature of a water tank provided on the periphery of the specimen tank is measured. CONSTITUTION:A specimen is placed in the electric furnace of a specimen-fusing assembly A and fused in preselected temperature conditions. Then the fused specimen together with the melting pot is dropped and led to a specimen tank 7 of a measuring assembly B before being enclosed therein by instantly closing a sliding cover 8. In the measuring assembly B, an internal water tank 9 is filled with water beforehand, whereas an external tank is filled with warm water. The specimen tank 7 is heated by the dropped fused specimen as it is subjected to high temperature transferred therefore, thus the water in the internal water tank 9 is rapidly heated. A rise of the water temperature therein is detected by two pieces of sensors 12 and the calory retained by the fused specimen is computed. |
