我公司研制開(kāi)發(fā)的高溫高鋁陶瓷是核電、高鐵、風(fēng)電鑄件專用系列產(chǎn)品，是國(guó)內(nèi)供應(yīng)核電鑄件主泵泵殼（華龍一號(hào)主泵泵殼）的鑄造輔材高溫陶瓷澆道供應(yīng)商，我公司與核電鑄件生產(chǎn)企業(yè)進(jìn)入深度合作，產(chǎn)品性能穩(wěn)定，深受客戶好評(píng)。高溫莫來(lái)石陶瓷是高溫合金鑄件專用系列產(chǎn)品，其材質(zhì)純白，透氣性更優(yōu)，適合高溫合金鑄件澆鑄要求,以上兩個(gè)系列的產(chǎn)品的主要優(yōu)點(diǎn)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℃）,耐沖刷，澆注后澆道內(nèi)表面無(wú)熔蝕，解決了澆道熔蝕物進(jìn)入鑄件本體。(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）化學(xué)穩(wěn)定性好,高溫下不與鑄件的金屬熔液發(fā)生化學(xué)反應(yīng)，解決了因澆道產(chǎn)生的金屬污染。(2) Good chemical stability. It doesn’t react with metallic solution under high temperture; and it solves metal contamination caused by pouring gate.

（3）抗熱震性能強(qiáng)，澆注過(guò)程中無(wú)炸裂，解決了澆道碎片進(jìn)入金屬熔液。(3) Strong earthquake resistance and no blasting in pouring. And it solves the problem that the debris of pouring gate enters metallic solution 。

（4）透氣性能優(yōu)，能有效排除氣體，解決了澆注過(guò)程中澆道產(chǎn)生的氣孔缺陷。(4) Good air permeability. It can effectively exhaust air and solve blow hole defects of pouring gate in pouring。
