Standard Test Method for Measuring Consistency of Self-Flowing Castable Refractories

Importancia y uso:

5.1 This test method is used to measure the consistency (degree of self-flow) that a castable refractory demonstrates at a given level of tempering liquid at specified time intervals after the liquid is added. A self-flow of 25 % has been selected as the minimum at which a mix can be poured into typical molds or forms in normal practice.

5.2 Castable refractories which are self-flowing at one level of tempering liquid will require vibration for placement at some lower level of tempering liquid. At the tempering liquid levels which require vibration or tamping for placement, the castable refractory should be characterized using test methods which are appropriate for castable refractories designed for vibration placement, such as Test Method C1445.

5.3 This test method is not appropriate for determining the pumpability of castable refractories.
