Dry Barrier Mix (DBM) is a refractory material made from a blend of high quality raw materials. It is mainly used to form a barrier between the surface of molten metal or slag and the refractory lining of the furnace.
Dry Barrier Mix (DBM) is a refractory material made from a blend of high quality raw materials used to form a barrier between the surface of molten metal or slag and the refractory lining of furnaces or other high temperature equipment.DBM is typically applied as a thin coating on top of the refractory lining to act as a barrier to prevent damage from molten metal or slag penetrating the lining.
Excellent moisture resistance
DBM is highly resistant to wetting by molten metal and slag, which helps prevent damage to the underlying refractory lining The barrier formed by DBM prevents molten metal or slag from penetrating into the refractory lining and causing damage.
High Temperature Resistance
DBM can withstand extremely high temperatures, up to 1800°C (3272°F). It is suitable for use in furnaces, ladles, intermediate ladles and other high-temperature equipment.
Easy to apply
DBM can be applied using a variety of techniques, including troweling, spraying and tamping. It creates a thin, uniform coating on top of the refractory lining.
You can contact us to customize the composition of DBM to meet the specific requirements of different applications. This allows you to optimize performance and cost-effectiveness for each specific use.
Good bond strength
DBM has good bond strength to the underlying refractory liner, helping to ensure a secure and long-lasting barrier layer.
DBM has a low shrinkage rate after installation and curing, helping to maintain the integrity of the thermal barrier and reducing the risk of cracking or other damage.
DBM is used in steelmaking to protect the refractory lining of ladles, intermediate ladles and other high-temperature equipment from corrosion by molten steel and slag.
Non-Ferrous Metal Production
DBM is used in the production of non-ferrous metals such as copper, aluminum and nickel to protect the refractory linings of furnaces and other processing equipment from corrosion by molten metal and slag.
Foundries use DBM to protect the refractory linings of ladles and other equipment from corrosion by molten metal and slag.
DBM is used in glass manufacturing to protect the refractory lining of glass furnaces from molten glass and slag.
Petrochemical and Chemical Processing
DBM is used in the petrochemical and chemical industries to protect refractory linings of process equipment from chemicals and high temperature processing.
