である。[Prior art/problems] Refractories for sliding nozzles consist of an upper nozzle, a fixed plate, a sliding plate, and a lower nozzle, and these refractories are made of high alumina, magnesia, or alumina-carbon. ing. Plate bricks are used after being subjected to pitch impregnation treatment. However, all of these refractories lack spalling resistance and cracks occur radially toward the nozzle hole during use.
Molten steel is inserted into this crack, causing localized melting loss. In addition, since the sliding plate shields the molten steel, the molten steel solidifies on the stop surface, causing the sliding surface to seize and peel off. In order to suppress these losses fJ7j, the pitch is impregnated especially for play 1 bricks, but since this pitch emits smoke during use, environmental improvement is required. It has been previously discussed that the wear caused by the above-mentioned cracks is influenced by the bond strength, structure, elastic modulus, and expansion coefficient of the refractory, but it is clear that the wear caused by the force L1 on the sliding surface is The reality is that no countermeasures have been taken.

し、カーボンの酸化防止にも効果がある。[Function] By distributing fused silica to the conventionally used refractory for sliding nozzles made of alumina and carbon, the expansion coefficient and elastic modulus of the refractory can be reduced, thereby making it possible to This makes it possible to suppress cracks that tend to form radially. Furthermore, on the operating surface, this molten silica absorbs F in the molten steel due to the lifting force that comes into contact with the molten steel.
Since it reacts with the eO component and the MnO component to form a glass layer, it improves the releasability of the solidified base metal and is classified as Class 1.
Ten damage can be reduced. In addition, fused silica reacts with carbon and CO gas during use, decomposes and evaporates into SiO gas, and condenses around alumina particles and carbon as Sing, contributing to improving the strength of refractories for sliding nozzles. It is also effective in preventing oxidation.

に好ましくない。The alumina used as a refractory aggregate can be, for example, fused alumina, sintered alumina, or temporary T/J alumina.Alumina is an aggregate necessary to maintain corrosion resistance, and the addition of alumina 55 to 89% by weight of E is suitable. If the amount of alumina added is less than 55% by weight, it is undesirable because the corrosion resistance will decrease,
Exceeding this is not preferable because the amounts of fused silica, carbon and sintering aid added will be insufficient, resulting in problems with spalling resistance.

ために好ましくない。Any vitrified (amorphous) fused silica containing 90% or more of 5iQz can be used as the aggregate, and fused silica is preferred, for example. The addition ratio of fused silica is preferably 3 to 20% by weight. If the amount of fused silica added is less than 3% by weight, it is undesirable because it has no effect on improving durability and preventing molten steel from burning, and if it exceeds 20% by weight, too much 5i02 volatilizes. This is undesirable because pores are formed and corrosion resistance deteriorates.

If the amount of the sintering aid added is less than 1×26, the effect of the addition will be insufficient, which is undesirable, and if it exceeds 5% by weight, the strength and elastic modulus of the refractory will become too high. Metal silicon powder, metal aluminum powder, or boron carbide powder, which is undesirable because it causes a decrease in spall resistance, is 1
