Description

Technical Field

At present, the sleeping material method of production enterprises is the traditional static sleeping material, that is: various raw materials are measured and put into the mixer according to the designed proportion, water is added and stirred, and the discharged materials are piled on the ground in a circular pile, and the surface is covered with plastic film and then left to sleep. However, this static sleeping material The water absorption rate of the upper and lower layers of the trapped material method is different. The bottom layer material that absorbs enough water can fully expand, while the upper layer material has water sinking, and it is difficult for the upper and lower layers to have the same expansion results in the same period of time. Therefore, during the subsequent high-temperature sintering, the performance of various raw materials cannot be fully reacted, and the new material crystal phase is unevenly distributed, resulting in insufficient material toughness and low flexural strength. For this reason, it is necessary to improve the uniformity of water absorption of refractory materials to achieve uniform and sufficient expansion effect. At the same time, it is necessary to improve the operational flexibility of processing and use, and to facilitate adjustment according to the operating volume of different refractory materials.
