    • A composition suitable for use in the plugging of tapholes of a metallurgical furnace is provided, which comprises a mixture of 60-80% refractory and erosion-corrosion resistant grain material, 12-18% binder substantially on the basis of tar products, and 4-12% bonding clay. Preferably: the binder contains 65-75% of electrode pitch, 9-11% of C.sub.2 -resins and has a viscosity less than 8000 cp. at 20.degree. C; the refractory consists 20-40% of sieve fractions of approximately 3-6 mm, the balance being of finer grains; the composition also contains ground soft coal, approximately to 10%; the refractory is burned magnesite with over 80% MgO content, or a mixture of 56-100% of Al.sub.2 O.sub.3 and from 0-44% SiO.sub.2, or a mixture containing 50-100% SiO and from 0-50% SiO.sub.2 ; and the refractory material contains impurities reducing its sintering point toward or below 1300.degree. C.

    • A sealing plug 1, consisting of fireproof material 10 located between the upper shaping plate 19 and the lower shaping plate 20, is used to seal the tap hole 3 of a tiltable converter 2. Said fireproof material 10 consists of bonding clay, water, oil and other constituents, particularly of 10-30% by weight hollow glass balls made of “foam glass” produced from recovered glass which have a rough surface suitable for binding large volumes of moisture. The sealing plug 1 thus retains the necessary stability even over longer periods and can thus be shaped in the tap hole 3 so that it is arrested against the wall 28, even after longer periods of storage. The hollow glass balls 11, 12, 13, 14 also entail a significant reduction in the weight of the entire sealing plug 1.
    • 由位于上成形板19和下成形板20之间的防火材料10组成的密封塞1用于密封可倾斜转换器2的排出孔3.所述防火材料10由粘土,水,油 和其他成分,特别是10-30%重量的由回收玻璃制成的“泡沫玻璃”制成的中空玻璃球,其具有适于粘合大量水分的粗糙表面。 因此,密封塞1即使在更长的时间内仍然保持必要的稳定性,并且因此可以在排水孔3中成形,使得即使在更长时间的储存之后它仍被阻挡在壁28上。 中空玻璃球11,12,13,14也显着降低整个密封塞1的重量。
