The present invention relates to a castable block for a coke oven door and a coke oven door.
The glaze is fired by heating at a high temperature of 0 ° C.
Since the heating temperature is as high as 1320 ° C., short metal fibers added to the castable block for the purpose of providing an anchor metal as holding means and reinforcing means or for improving strength, toughness and spalling resistance are oxidized and used. In addition, the castable block may be damaged due to factors such as oxidative expansion. For this reason, short metal fibers are not added, and an anchor metal cannot be provided. Therefore, the castable block has a complicated structure that is difficult to hold the castable block. Further, the cost and time required for heating the entire block and firing the glaze are enormous.

っている。For example, JP-A-6-60354 relates to a castable block provided with a glaze layer for a gas cooling chamber of a refuse incinerator, and a glaze is applied only to the surface of the castable block which is the inner surface of the gas cooling chamber of the refuse incinerator. Layers are provided and the entire block is heated to 1200 ° C. to fire the glaze. In this case, it is impossible to provide an anchor metal or to dispose short metal fibers for the reason described in the previous section because the entire block is heated. For this reason, it is a castable block having a complicated structure that is difficult to maintain.

する。In castable blocks subjected to thermal spalling, there are many demands for castable blocks containing short metal fibers in order to improve spalling resistance. However, in the current castable block with a glaze layer, the glaze is baked by heating the entire block. Therefore, the short metal fibers arranged in the block are oxidized due to the high temperature (about 1200 ° C) when the glaze is baked. There is a technical problem that cannot be achieved.

However, a castable block provided with a current glaze layer is obtained by firing a glaze by a method of heating the entire block. There is a technical problem that the anchor metal provided in the above cannot be oxidized due to the high temperature (about 1200 ° C.) at the time of firing the glaze and the initial purpose cannot be achieved.

術課題とする。The castable block for the coke oven door is
During operation, the castable block surface facing the furnace has a temperature gradient from the surface in contact with coke to the surface attached to the furnace door hardware. The temperature range from 1000 ° C to 1100 ° C in contact with coke and 200 ° C to 400 ° C near the surface attached to the furnace door hardware is wide.
It is unreasonable to provide a high temperature glaze layer on the entire castable block surface facing the furnace. Therefore, it is an object of the present invention to provide a plurality of glaze layers having different melting temperatures and establish a method for firing the glaze.
