How to molten steel carbon content is measured with a thermocouple

Using thermocouple measurement of molten steel in the initial solidification temperature, thus learned that the carbon content of molten steel, the new USES of the thermocouple in metallurgical testing techniques.

by metallography of the iron carbon equilibrium diagram shows: when the carbon content of less than 4. Of 32 cases, including the carbon in the molten steel at the higher, began to analysis the body of excessive degree is lower, and is a single value corresponding relation. Molten steel continuous cooling to a certain temperature will gradually solidified, the solidification due to the release of latent heat of crystallization in & other; Time & ndash; Temperature throughout the &; Characteristic curve appears on the obvious turning point, the inflection point said initial solidification temperature. Due to the carbon in the molten steel containing s different, it is its initial solidification temperature is different, so using thermocouple to measure initial solidification temperature of molten steel in the cooling process, according to initial condensate 161 A degree and the relationship between the carbon content, can learn this furnace carbon content of molten steel. It must be pointed out that in the molten steel in addition to iron, carbon, silicon, manganese, phosphorus, sulfur, oxygen, nitrogen, hydrogen and other elements, they reduce the solidification temperature of the molten steel respectively, should be appropriately modified.

2, measuring method has ap, upi, magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer measured

your solidification degree is a specially made miniature thermocouple, it is composed of a & other; U 'type quartz tube, tube wear has a diameter of 0. The platinum guy 10-1 mm Platinum and platinum guy a platinum rhodium thermocouple fixed 0 to 30 of refractory base, as shown in figure 7 32.

the measurement, the carbon head first love in the lower part of the special ceramic or cast iron sample cup, plug wire. After using samples are taken from the furnace of molten steel, aluminum deoxidation, immediately quick pour molten steel into the sample cup. Display instrument ( Electronic potentiometer or digital instrument) Immediately instructed and record the molten steel in the sample cup A& Degree and its change, when the cooling curve appeared inflection point, you can know that the carbon content of molten steel. Steel setting for the relationship between temperature and carbon content as shown in figure 7 33. Figure 7 - 34, FIG. 7 35 is the record of the measured curve. This method can also be used on the oxygen top-blown converter of sublance ( As mentioned above) , in the process of converting the M - The carbon content of molten steel.
