Way to Dry High Alumina Refractory Bricks In The Manufacturing Process
High alumina bricks are one kind of refractory bricks materials with main chemical component of Al2O3. As is proven to all that refractory bricks are made for heating equipment application such as fun time furnace and rotary kiln. Choose the right firebricks for the right position in the furnace or kiln. And the bricks' quality influences the air conditioner or kiln's service life. In order to get quality high alumina voilier application, you need to understand how to dry http://rsrefractoryfirebrick.com/high-alumina-refractory-bricks/ in the manufacturing process.
High alumina bricks can be split up into burnt high alumina brick, unburned large rock and resintering high alumina brick, which burnt high alumina brick is the refractory materials with large production and widely used. China is a great production place of uncooked materials for refractory. Rongsheng in China as a professional refractory bricks and materials manufacturer provides customers with high quality and low price high alumina brick. Now I will introduce you the developing process of high alumina brick.
Drying high alumina green brick is to eliminate physical water in the binding agent of green brick body. Mobilize the intensity of oriental brick body and reduce progressively the waste when inserting and firing large rock. High alumina brick is triggered liquefaction when drying out, that will raise the difficulty of operation. If the liquidation situation is important, the brick's bulk will expand that result the pattern damage in the process of drying. Green brick body in the process of drying, the made physical-chemical change, at the first stage, moisture of removing need better temperature, but the over high temp will speed up the body cracking. Special in the end period of drying, because the temperature and moisture transfer effect, the over temperature will not be advantage for removing the moisture. On the common condition, the air-in temperature of drying out medium should be between 100-120?, the air-out heat should be between 40-60?. Make sure the certain intensity and 0. seven percent moisture of green stone body after drying. Following drying green brick body should be put into kiln to prevent from efflorescence.
