High-Temperature Fire-Resistant Mortar
Category:
Refractory materials for roasting furnaces
Product Description
Currently, most refractory bricks used in lining the fire channels of roasting furnaces are laid using clay-based refractory mortar, which typically contains 45–48% Al₂O₃. This type of mortar is easy to manufacture, but during high-temperature operation, it suffers from poor bonding and flexural strength—both at low and high temperatures. As a result, under continuous exposure to intense heat and high gas pressures, the brick joints gradually loosen and eventually fall apart due to the relentless impact of hot gases. This leads to damage in the brick joints, causing the fire channel walls to sag and deform, ultimately shortening the service life of the furnace's fire channel lining.
Our company has developed and engineered a high-temperature refractory mortar specifically designed for lining the flue passages of roasting furnaces. This product incorporates organic and inorganic chemical additives, combined with modified clay, enabling it to maintain exceptional chemical bonding strength (>5.0 MPa) even at 110°C. Additionally, it exhibits outstanding adhesion across all temperature ranges—from room temperature up to 1400°C.
To facilitate transportation during construction, our company has developed two categories of refractory mud—water-based and adhesive-based.
