Principles for Choosing Refractories for Glass Furnace

Date of release:2019-03-13 Author: Click:

The overall objective of refractory selection for glass kiln is to consider both technical and economic factors comprehensively. Based on the physical and chemical properties, structural forms and critical service performance of refractories, the operating environment parameters of various parts of the kiln and the corrosion mechanism and mutual reaction of refractories at high temperatures, the accumulated detailed knowledge and practical experience on the actual operation performance of kilns and refractories are combined. Tests show that the refractories in different parts of the furnace are selected and matched reasonably so as to achieve corrosion balance, prolong service life and reduce the cost of the best use effect. Specific requirements are as follows.



(1) To meet the necessary performance, such as high temperature performance, chemical stability, thermal stability, volume stability and mechanical strength.


(2) It does not pollute the glass liquor and has little effect on the quality of the glass liquor.


(3) As long as possible service life.


(4) There is no contact reaction between refractories made of different materials at high temperature.


Minimum material consumption and heat dissipation loss.


High quality materials are used in vulnerable parts and general materials are used in other parts to achieve "reasonable matching and kiln age synchronization".


When selecting refractories for glass furnace, the following rules should be followed:
