Standard Classification of Alumina and Alumina-Silicate Castable Refractories

Fecha:
2012-04-02 /Historical
Superseeded by:
Significance and Use:

Alumina and alumina-silicate castable refractories are produced to yield property characteristics commensurate with different end use properties. Volume stability, modulus of rupture, bulk density, and lime content have become useful measures to distinguish various alumina and alumina-silicate castable formulations for initial fitness for service. This classification is considered useful for purchase specifications and for quality control.

Scope:

1.1 This classification covers alumina and alumina-silicate castable refractories that, when tempered with water, will develop structural strength by chemical action.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Keywords:
alumina; alumina-silicate; castable refractories; insulating castable refractories; low-cement castable refractories; no-cement castable refractories; regular castable refractories; ultra-low cement castable refractories
