A design and production technology were developed for making fireclay two-piece elongated steelcasting nozzle batchers with an apparent porosity of 14-17%. The resistance of the nozzles is satisfactory and they form a satisfactory jet, despite the retarding action of the stopper plug. The nozzles are being introduced at the Novolipetsk Metallurgical Factory and their production organized at the Semiluki Refractories Factory. The use of elongated nozzles and improved insulation of the working zone in the crystallizer during the continuous casting of electrical-engineering and carbon steel permitted a substantial improvement to be made in the purity of the surface of the cast slabs and the quality of the metal, and also yielded 46,000 rubles annual savings.
