Dryer furnace temperature can reach 2100 degrees, before the use of refractory cement + quartz sand mixed furnace. Dryer in the continuous work 4-5 hours after the furnace part of the melt, need to cool the furnace and then paste the paste above the refractory material, dry before they can continue to use, so seriously affect the efficiency of the dryer. Is there any refractory material that can replace the combination of refractory cement + quartz sand so that the dryer can not be used for continuous use. It was suggested to build refractory bricks, refractory bricks of the upper limit temperature is not 1500 +? If this is the case, I can not solve the problem. Please all the way to high, we thank you! More
2100 degrees, what do you use? The The The And is the dryer? You are using low-melting substances are 1000 degrees can not carry. "The upper limit temperature of the refractory bricks is not 1500+?" You refer to refractoriness or use temperature. First of all you have a dryer can not reach 2100 if it is true, the oxidizing atmosphere suggests you use high chrome brick with high zircon brick. Nonwoimous atmosphere with silicon nitride brick. But it is estimated that you use clay brick on the line, but the price difference of hundreds of times! The The
Does the temperature measurement of 2100? At present, the longest temperature of the most resistant refractory bricks is around 1800 ℃. There are materials can be resistant to 2100 ℃, but the insulation performance is slightly worse than ordinary materials, and the price is more expensive,
Refractory refractoriness: magnesia bricks: more than 2000 degrees dolomite brick: more than 2000 degrees cast corundum brick: greater than the 1990 degree of the edge of the gallop of the old insects tame the paste as you described, the use of quartz sand and refractory cement mixed furnace Can work at 200 degrees for some time. But the fire resistance of quartz sand products generally only about 1600-1700. Then more than three kinds of refractory fire resistance are higher than the quartz sand about 300 degrees, you should be enough to use.
Combined with the first floor, the second floor of the point of view!
