Calcium-free Silica Brick
Features of Calcium-free Silica Fire Brick
• Low porosity
• Good thermal shock resistance
• High load softening temperature
• Good high temperature performance
• Glass industry: commonly used in the heat storage chamber, small furnace, pool wall and other parts of glass kiln;
• Metallurgical industry: in some special metallurgical furnaces, such as reverberatory furnaces and electric furnaces used for non-ferrous metal smelting, calcium-free silica bricks can be used as lining materials for furnace tops, furnace walls and other parts;
• Other industrial kilns: in industrial kilns such as ceramics and refractory materials, calcium-free silica bricks are selected as refractory materials for some key parts.
