High alumina refractory poly insulation brick
High aluminum poly light brick with a small density, low thermal conductivity, thermal insulation performance, quality and stability characteristics. Can be used for all kinds of high-temperature furnace lining or insulation layer. Using the mechanism of a molding, burned into the method of manufacturing technology, while retaining the traditional bubble to light law, casting molding, product cross-section structure is uniform, stomatal formation of complementary honeycomb, so that the product pressure strength and thermal insulation performance can reach the most Good level. All products shape all grinding and shaping, size deviation is small, to meet the special needs of furnace masonry.
