High Aluminum Insulating Castable Refractory for High-temperature Industrial Kilns

The main material of our high alumina insulating castable refractory is Al2O3—SiC—C,there’s 2 types including baking casting material and free baking material, the width of iron runner is required above 2.4 meter, the depth is above 1.7 meter, it has a good performance in site operation, with easy repair, tapping iron is allowed after pouring finished. Although the invest is more higher for once time, but it will be with a longer service life and a few mending work.
