Selection of quality mullite castable come Tianjin Gute saving performance mullite castable with a high purity, low impurity quality synthetic mullite raw materials, and strictly control the matrix composition, forming a network skeleton mullite structure, making castable hot strength improved, enhanced anti-erosion castable performance, extended service life. Due to the thermal expansion coefficient of mullite 5.7 * 10-6 / ℃, good volume stability, so good thermal shock resistance, while the rod-like mullite crystals, anisotropic thermal expansion insulation castable, so castable During the sintering process to form a large number of internal microcracks, improve castable toughness, thermal stress buffer, terminate crack propagation. High-performance mullite castable has high thermal shock resistance and anti-structural spalling resistance, good thermal shock resistance, high load softening point, a small high-temperature creep, hardness, chemical resistance and good features. Always welcome your inquiry, castable want to know more details, please contact customer service online, you can directly call toll free Anhui insulation castable, we wholeheartedly at your service! Tianjin Gute energy saving Technology Co., Ltd. is the most professional technical service provider in Shandong refractory lining insulation castable refractories have the best and the best installation services team has extensive experience in providing customers with the best quality service . Aluminate cement varieties, different varieties, preparation of low cement castable refractory also differ. For example, in the mix and the same basic conditions, CA-50 and CA-70 cement cement consumption is 5%, the drying, 800 ℃ and 1100 ℃ after burning compressive strength, the former were 45Mpa, 51Mpa and 59 Mpa Jiangxi insulation castable, the latter corresponding to 65,70 and 74 Mpa. This shows that the use of CA-70 cement formulated low cement castable performance, superior to CA-50 low cement castable cement formulated, but the cost increase slightly. With the same basic castable, refractory powder and keep a constant amount of cement. The minimum amount of cement, should ensure that there is adequate room temperature strength, in order to meet the low cement castable form removal or lifting of the technical requirements. The compressive strength at room temperature castable were 15Mpa and 22Mpa. In 1100 ℃ before, more than the amount of cement, high strength after firing at 1400 ℃ and 1500 ℃, the two are similar, with a small amount of cement slightly higher.
