AB - GAS-PERMEABLE BLOCKS MADE FROM SILICATE LIQUIDS V. P. Nemchenko, D. V. Kotsyuba, UDC 666.651.2:669.184.224.3 A. V. Mokrinskii, and D. M. Galant Extensive use is made in modern steel-melting practice of buckets, converters, and arc furnaces in which gas is supplied to the metal through the bottom lining. There is fairly rapid wear on the bottom lining, which requires techniques for periodic hot repair (e.g., lining) with the retention of gas permeability in the repaired layer. One approach is to freeze a layer of liquid slag there with continuous gas blowing [1]. The scope for this method is examined here. The laboratory experiments were performed with a resistance furnace (Fig. 1) having a tubular carbon heater. The crucible was placed in the isothermal zone, with the walls provided by a graphite robe. The cylindrical periclase bottom had one axial hole with diameter 1-2 mm or was formed from a porous material having a gas permeability coefficient of 22/xm 2, open porosity 25%, and mean pore radius 70-100 ~m. We melted 450 g of the silicate Na20-SiO2, melting point about 800~ in the crucible and superheated it to 1300~ This layer of liquid with diameter and depth of 60 mm was
