In the conventional sliding nozzle device,
When setting the bricks that would become the plates, lubricant was applied to their sliding surfaces. However, when such a lubricant is applied, the lubricant is burnt out in a short time due to the heat generated when the molten metal flows out, and the sliding lubricity deteriorates significantly in a short period of time. In addition, carbon substances such as tar, pitch, and other organic substances filled and impregnated into the pores on the plate surface are also burned away by the coating. As a result, the structure of the plate surface becomes brittle, and as a result, molten metal is easily caught in, scratched, and inserted into the base metal, and damage to the sliding nozzle is accelerated. As described above, conventional lubricant application causes a loss of damper performance and is accompanied by various problems.
本発明は、従来の潤滑剤塗布におけるこのよう

In view of such problems in conventional lubricant application, the present invention utilizes the heat of molten metal to constantly supply a damage prevention material or repair material to the sliding surface of a sliding nozzle, thereby improving the sliding surface of the sliding nozzle. The purpose is to always maintain it in good condition.

In order to achieve this purpose, the present invention provides that after a plate is attached to a molten metal container etc., a damage prevention material or a damage repair material that is softened or liquefied by the heat of the molten metal is embedded in the upper plate. It is characterized by causing a softened or liquefied damage prevention material or damage repair material to flow down toward the sliding surface. As a result, the damage prevention material or damage repair material softened or liquefied by the heat of the molten metal flows down and evenly spreads over the sliding surface.

As explained above, according to the present invention, the damage prevention material or repair material embedded in the plate of the sliding nozzle device is softened or liquefied by the heat of the molten metal and spreads over the entire sliding surface. As a result, a coating is formed on the sliding surface or a damaged portion is repaired. Then, when the plate is opened or closed in the next step, this coating or filling part functions as a damage protection membrane, preventing direct penetration and contact with molten metal and also reducing the penetration speed. The damage protection membrane may be washed away by the molten metal flow, but it protects the molten metal until it is washed away, and cushions the shock upon the initial impact of the molten metal flow. A similar effect can also be obtained by actively rinsing the area after each sliding movement. Due to the heating action, the damage prevention material of the filling part may be baked in this part to protect the sliding nozzle. In this way, the action of forming the damage-preventing film is repeatedly and continuously performed, and an excellent damage-preventing effect can be continuously obtained. In addition, when a suitable damage prevention material or repair material is selected in consideration of operating conditions, firebrick material, damage behavior, and other conditions, the damage prevention effect will be even better.

解消できる。 In addition, since damage prevention material or repair material is constantly supplied around the nozzle hole of the plate,
In the unlikely event that a drop in surface pressure occurs, metal leakage or hot water leakage can be prevented, and device failures due to inability to close can be completely eliminated.

トの損傷をも防止される。 Furthermore, gas leakage that tends to occur when blowing gas to prevent solidification of molten metal or to degas it, and damage to the plate due to the bubbling effect caused by it, are also prevented.

となり、溶融金属の凝固が防止できる。 Supplying the damage prevention material or the repair material makes it possible to cool the sliding surface, and it becomes possible to obtain a good sliding contact state without the need to excessively increase the contact accuracy of the sliding surface. Furthermore, by selecting the type of damage prevention material or repair material, it becomes possible to heat and bubble the inside of the nozzle hole and the molten metal itself, thereby preventing solidification of the molten metal.
