Anti-stripping Performance of Magnesium-calcium brick
During the use of magnesium-calcium bricks , the working end is cracked and peeled off due to changes in furnace temperature and slag penetration. Therefore, improving the spalling resistance of magnesium-calcium bricks is also one of the main ways to increase the service life of magnesium-silica brick linings. The pores in the magnesia calcium bricks can buffer the thermal stress in the magnesia-calcium bricks, prevent cracks from being generated and further expand, and help to improve the heat-stripping performance of the magnesia-calcium bricks . However, the pores in the magnesia-calcium bricks make it easier for the slag to infiltrate into the interior of the brick, forming a thicker deteriorating layer, and accelerating the structural peeling of the magnesia-calcium brick . Therefore, in practical applications, comprehensive consideration should be given to various factors to determine the porosity of magnesium-calcium bricks. In the production of magnesium-ca...
