CARBON-CONTAINING REFRACTORY, METHOD FOR MANUFACTURE THEREOF, AND PITCH-CONTAINING REFRACTORY RAW MATERIAL
A configuration in which particles of pitch 2 having a softening point in the range of 70 to 200°C and a diameter equal to or smaller than 30 µm are held on the surfaces of particles of a refractory raw material 3 having a diameter equal to or smaller than 50 µm is employed. This pitch-containing re...

| description | A configuration in which particles of pitch 2 having a softening point in the range of 70 to 200°C and a diameter equal to or smaller than 30 µm are held on the surfaces of particles of a refractory raw material 3 having a diameter equal to or smaller than 50 µm is employed. This pitch-containing refractory raw material 1 can be used with the pitch being in a fine-particle form without any aggregation even after the long-term storage. Using it as a part of a raw material formulation allows the fine particles of pitch to be uniformly dispersed during the mixing or kneading process. The resulting carbon-containing refractory has an excellent corrosion resistance. It also provides suppressed increase in the Young's modulus while maintaining the level of strength, thereby being excellent in thermal spalling resistance even with the carbon content ratio being low. |
