Put the dried mafic aluminum spinel brick and the forsterite composite brick green body into a high-temperature furnace, heat up to 1550° C. and heat it for 5 hours after holding for 5 hours. The mafia-iron-aluminum spinel brick and forsterite composite brick are made, and after cooling, they are taken out for taking pictures and then tested. Ordinary fused magnesia, at different temperatures of 1500 ℃ and 1550 ℃, the linear change rate of mafia-iron-aluminum spinel and forsterite composite bricks after firing. They are the composite brick samples of fused magnesia-aluminum-iron spinel and forsterite bricks at a firing temperature of 1500°C and the composite brick samples of sintered magnesia-aluminum-iron spinel and forsterite bricks. They are the sintering temperature of 1550 ℃, the composite brick samples of fused magnesia-aluminum-iron spinel and forsterite bricks and the composite brick samples of sintered magnesia-aluminum-iron spinel and forsterite bricks. At the same sintering temperature, the linear change rate of the composite brick of fused magnesia-aluminum spinel and forsterite brick after firing is lower than that of the composite brick of sintered magnesia-aluminum spinel and olivine brick. rate. Heavy burnt magnesia manufacturers

The linear change rate of the composite brick of magnesia-aluminum-iron spinel brick and olivine of the same material increases with the increase of its firing temperature. Linear change rate after firing of magnesia-iron-aluminum-spinel and forsterite composite bricks at different sintering temperatures. Linear expansion of mafic aluminum spinel brick and high-purity forsterite brick Linear expansion of high-purity forsterite brick and mafic aluminum spinel brick. Thermal expansion curve of fused magnesia-iron-aluminum-iron spinel brick sample after firing. From room temperature to about 1500°C, the linear expansion rate gradually increases, and at about 1500°C, the linear expansion rate shows a large value without a significant drop. Therefore, the linear expansion rate of fused magnesia-iron-aluminum spinel bricks is steadily increasing from room temperature to 1500°C.
