<p><P>PROBLEM TO BE SOLVED: To provide a stave in which poor abrasion resistance is improved while maintaining excellent thermal conductivity, and the heat removal amount is stably suppressed small to achieve life extension. <P>SOLUTION: The stave includes: a stave body 1 made of copper or a copper alloy and having a plurality of horizontal grooves 1a formed on the front surface to be used as a furnace inner side; and metal block materials 2 inserted into the horizontal grooves 1a of the stave body. The block material 2 has such a height that when it is inserted into the stave body 1 with gaps 8a on the upper and lower surfaces, it forms a flat surface with the front surface of the stave body 1, and it has a shape of trapezoid which is in agreement with the horizontal groove 1a of the stave body 1 and in which at least one of the upper and lower surfaces is inclined. Further, the block material 2 can be stably fixed with an insert bolt to further enhance the cooling effect of the block material 2. Combining the metal block material on the front surface can prevent the contact wear, the crack, and damage of the stave body with a filling materials in a furnace. In addition, the block material can properly suppress the heat removal amount and prevent the deterioration of the fuel consumption rate due to an excessive heat removal amount. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
