Abstract: A kind of high temperature furnace lining energy economized coating BJ-Ⅰ has been developed. The role of the blackening agent, such as SiC, was studied. It has been found that the increment in emission ratio began to show down when the blackening agent content was more then 12%. The adhesion strength and stripping and splitting prevention measure were also discussed. The results showed that BJ-Ⅰ coating possessed high adhesion strength and tenacity. It has a protective effect on the lining and can protract the service life of the lining effectively.
