The gunning mix is prepared with magnesia and magnesia-calcium materials and binding agents and sintering agents. It is characterized by high bonding strength, strong corrosion resistance and not easy to fall off. It is suitable for spray repair of steel-making converters and electric furnace linings. Extended service life. When the hot repair temperature of the lining is greater than 1000℃, the hot spray repair effect is better, and the adhesion rate is greater than 85%.
