Hexiang Magnesium Oxide Manufacturer tells you the refractory degree of refractories?

Refractories are important basic raw materials to support the development of high temperature industry, and play an important role in the development of high temperature industry. However, the refractory industry in China has a series of problems, such as overcapacity, low industrial concentration, unreasonable industrial structure and poor international competitiveness. Through the establishment of strategic alliance of technological innovation in refractory industry, it is of great significance to effectively integrate the resources of technological innovation in refractory industry, to construct a successful, long-term and stable mechanism of cooperation between industry, University and research, to straighten out the chain of industrial innovation, to enhance the technological innovation ability of refractory industry, to enhance the core competitiveness of industry, and to effectively support the technological progress of high-temperature industry in China.

The refractoriness of refractories means different from melting point. The melting point is the temperature at which the liquid phase and solid phase of the crystal are in equilibrium. Fire resistance is the temperature at which the multiphase reaches a certain softening degree. For most ordinary refractories, they are heterogeneous materials without a certain melting point. It is a gradual process from liquid phase to complete melting. In a wide range of high temperature, solid and liquid coexist. Therefore, in order to characterize the softening and melting characteristics of this material at high temperature, only the refractoriness can be used to measure it.
