AN APPARATUS AND METHOD FOR DETERMINING THE PERCENTAGE OF CARBON EQUIVALENT, CARBON AND SILICON IN LIQUID FERROUS METAL

摘要

The present invention relates to an apparatus and method for determining the percentageof Carbon Equivalent, Carbon and Silicon in liquid ferrous metal. The apparatus of the present invention comprises of refractory cup structure (2), cavity (1), thermocouple wire (4), quartz tube (3), base (6), tellurium (5), holder (7), compensating cable (9), electronic device (8). The method of present invention comprises steps of a Pouring of sample in refractory cup. b. Recording maximum temperature of the sample and allowing it to cool to solidification temperature. c. Determination of liquidus temperature, this temperature being inversely proportional gives percentage of carbon equivalent using algorithm. d. determination of solidus temperature using algorithm. e. the determination of percentage of carbon and silicon using electronic device(8) based on algorithm. The present invention relates to the detection of the composition of liquid ferrous metal in a much quicker time using refractory cup.
