The lower limit is determined by the fact that the slag that has remained after the pouring of steel may affect the resistance of the end caps. For determining the dynamic measurement error, we used the average time constant of the thermocouple, which was placed in the end cap and exposed to plex heat exchange conditions. The information on temperature is used during the second half of smelting in order to prevent overheating and to bring the metal to the assigned pouring temperature. During this period, the temperature variation rate lies within 10 40~ so that the dynamic error will be in the 7a0 ~ range. However, by feeding this information to a puter, a theoretical correction for the dynamic error can readily be introduced and the error reduced to a negligible quantity. Thermostatic control of the thermocouple39。s perimeter. With the thermocouples installed at different levels in the metal zone, we recorded the beginning and the rate of changes in the metal temperature at the moment when the cooling admixtures were added and also the rate of temperature increase during the blowingthrough process. The thermocouples were mounted at distances of 320 and 800 mm from the converter39。s bottom, the end caps lasted throughout the entire smelting process. It has been established by investigations that, in parison with the chemical action of slag, the effect of metal convection flow on the durability of end caps is negligible. The end caps fitted into the lining (Fig, 1, 3) were screened from the flow by refractory brick. This did not improve their resistance. Simultaneously with testing the resistance of end caps at the insertion place, we determined the degree to which the temperature readings were
