我公司研制开发的高温高铝陶瓷是核电、高铁、风电铸件专用系列产品，是国内唯一供应核电铸件一级主泵泵壳（华龙一号主泵泵壳）的铸造辅材高温陶瓷浇道供应商，我公司与核电铸件生产企业进入深度合作，产品性能稳定，深受客户好评。高温莫来石陶瓷是高温合金铸件专用系列产品，其材质纯白，透气性更优，适合高温合金铸件浇铸要求,以上两个系列的产品的主要优点有：High-temperature and high-alumina ceramics developed by our enterprise is the specialized series products for nuclear power, high speed rail and wind power casting. As the only domestic provider of high-temperature ceramics pouring gate, as the auxiliary material of nuclear power casting class 1 case of main pump (case of Hualong No.1 pump), we deeply cooperate with nuclear power casting manufacturer to produce the products with stable performance which are appraised by customers. High-temperature mullite ceramics is the specialized series products for high-temperature alloy casting. Owing to its features of pure white texture and better breathability, it meets the casting requirements of high-temperature alloy casting. The above two series products have the following advantages:
（1）耐火度高（＞1750℃）,耐冲刷，浇注后浇道内表面无熔蚀，解决了浇道熔蚀物进入铸件本体。(1) High fire-resistant degree (>1750℃), washing-out resistance, no corrosion in the internal surface of pouring gate after pouring. It solves the problem that corrosives enter casting。
（2）化学稳定性好,高温下不与铸件的金属熔液发生化学反应，解决了因浇道产生的金属污染。(2) Good chemical stability. It doesn’t react with metallic solution under high temperture; and it solves metal contamination caused by pouring gate.
（3）抗热震性能强，浇注过程中无炸裂，解决了浇道碎片进入金属熔液。(3) Strong earthquake resistance and no blasting in pouring. And it solves the problem that the debris of pouring gate enters metallic solution 。
（4）透气性能优，能有效排除气体，解决了浇注过程中浇道产生的气孔缺陷。(4) Good air permeability. It can effectively exhaust air and solve blow hole defects of pouring gate in pouring。
