1. Refractoriness of fused cast azs block
Refractoriness of fused cast azs block refers to the property that refractory’s multiphase
reaches to a specific softening degree when at high temperature without any load, which
shows the ability of resistance to high temperature. It is a basic scale to measure the ability of
resistance to high temperature and basic technical index to show its high temperature
property. Meanwhile, refractoriness is an important index to judge whether this refractory
product is suitable to buyer’s high temperature furnace. One thing we need to know is that
only if the refractoriness of Inorganic non metallic materials up to 1500 can be called℃
refractory material.
Refractoriness is different from melting point, melting point is the balance temperature that
materials reach to melting point which is between solid and liquid crystal, however,
refractoriness is a process in which the solid phase of the material is gradually dissolved in
the liquid phase and finally is melted with the increasing temperature.
The chemical and mineral composition, distribution and combination of each phase have a
decisive influence on refractoriness of refractory, such as fused cast azs block. All kinds of
impurities can seriously reduce the refractoriness, so it is pretty important to improve the
purity of raw material and strictly control the content of impurity.
However, in actual application, besides the high temperature, refractory is also corrosive by
other impurity, working environment is quite complicated, so refractoriness is used as a
reference, and can not be more accurate data.
Zhengzhou Sunrise Refractory Co., Ltd. is mainly engaged in the research and development
of refractory products. Sunrise can provide fused cast AZS series block which has passed the
ISO international certified. Over 30 years producing and marketing experience, with reliable
