Property

1.Chemical compose : main component determine quality and characteristics of refractory material.

2.Bulk density : density large, good compactness, high strength, may a large thermal conductivity .

3.Apparent porosity : non-specific request, but must be strictly controlled as apparent porosity for manufacturer.

4.RUL : high temperature resistant ability.

5.Resistant thermal shock performance : resistance to sudden temperature change capacity without being destroyed.

6.Compression resistance : bear ( room temperature ) maximum pressure capability.

7.Breaking strength : ability to withstand the shear stress.

8.Linear rate of change : refer to the expansion and contraction in volume occurs at the same temperature change , if each same , we define such change is zero.

Physical and Chemical Indication

1.Wear : it is one of the best indicators to ensure quality for refractories.

2.Thermal conductivity : heat flow rate in per unit area.

3.Impact resistance: good impact resistance, long service life.

4.Slag resistance : ability to resist high temperature and a small role in the erosion of slag without being destroyed.
