New ceramic sand (powder)
It is a type of new refractory material developed by Lianxin Foundry Sand Group, which includes two series namely AL-Zr series, Al-Si series. the refractory is made of high alumina ore and zircon ore as the main material, processed by raw material preparation, melting by arc furnace, crushing, washing, drying, grinding, and adding a certain proportion of functional additives. This product is a neutral refractory material with the characteristics of high refractoriness, small thermal expansion coefficient, compact structure, low content of low melting point substances, and high cost performance. the new ceramic refractory are perfectly suitable for using in investment casting process instead of zirconium sand (powder).
