Method and apparatus for testing of materials using measures of differential temperatures.

摘要

Method and apparatus for testing of materials using measures of temperature differentials.The invention relates to a method and a device for convenient and precise measure of parameters of materials are described.A test sensor (30) measures the temperature of a sample of material as it is heated and / or cold.A reference sensor (20) is used to obtain measures of temperature differentials in the measure in which the temperature of the test specimen is varied.A trace of the temperature differential is generated and analyzed to determine various characteristics of the material under test.In one implementation,The relationship of sodium fluoride to aluminium fluoride (NaF: ALF ~ 3 ~) and the concentration of alumina in a merger of aluminium in a hall are determined to control efficientlyThe fusion of metallic aluminum.In this implementation,The temperature of the bath and the liquid temperature can be measured and compared to determine the degree of superheat of the bath and to prevent operation of the casters at higher temperatures thanThe necessary.
