【正文】 representative of the temperature of the converter bath. On the basis of the converter39。s lower conical part (Fig. 1). In* The zirconiumboride cases were developed at IMSS, Academy of Sciences, Ukr. SSR, under the supervision of G. V. Samsonov, Corresponding Member, Academy of Sciences, Ukr. to test the resistance of the end caps in the metal, they were inserted through the lining at the same level betweenthe bottom and the slag. The thermoelectrodes were encased in a narrow alundum tube (Fig. 2), and the junction was place in an alundum end cap, which was protected by means of a zirconiumboride cap, after which the thermocouple was place in a metallic tube. After the first experiments, the alundum end cap was made longer in order to protect the thermoeouple from shorting by the metal that has perated the lining. The misgivings concerning the possibility of the metal escaping through the entrance opening were not justified. During the first melting after the thermocouple was installed, the molten iron perated the thermoeouple entrance opening, sometimes even appearing on the outside of the casing, but it solidified, thereby automatically sealing the thermocouple. The metallic tube protected the thermocouple from damage during the laying and heating of the lining and also from the moisture in refractory clay. A deflector (Fig. 2, 1) consisting of one or two bricks was provided above the protruding end cap in order to protect it from being damaged by a piece of brick in laying the upper rows of lining, a piece of ore, or a piece of lime when cooling additions are introduced in the bath. As was expected, the resistance of the end pieces was greater when theywere located closer to the converter39。 MEASUREMENT OF THE METAL TEMPERATURE IN 50TON CONVERTERS BY MEANS OF HERMOCOUPLES PROTECTED BY CERMET ZIRCONIUMBORIDE END CAPS S.
