The invention solidifying a melt, as a clot prognosis device for predicting the solidification of water state, located in the vessel upper side the melt accommodated, elevating is possible and is provided with a refrigerant flow path for the refrigerant is moved to the inside, wherein the surface is installed so as to surround the inner body in the inner body, the outer side of the inner body melts, this coagulated clot is formed to have an area to be formed to expose at least a portion of said inner body surface, elevating possible outside the body, the inner is connected to a body side that are formed extending in the width direction of the vibrating device, inside the body for generating a vibration to the inner body, at least a portion is provided inserted in the inner body so as to be positioned in the inner body, measuring the temperature inside body warmth, calculating the heat flux in the inner body using a measured temperature from the warm side, and by using the calculated heat flux values ​​comprises a module for predicting the prognosis of coagulation water quality conditions coagulation inside the body surface.
Therefore, by, according to the embodiment of the present invention and to the casting condition of the continuous casting process, applied to the simulator forming the clot, prognosis coagulation water quality state formed by calculating the heat flux of this time, water coagulated in a simple way compared to the prior Wisdom can be a quality status. Therefore, there is an advantage which can shorten the time and the process of analyzing the solidified water quality through a clot simulator.
