Tundish containing beryllium oxide coating and preparation method thereof
The invention discloses a tundish containing a beryllium oxide coating and a preparation method of the tundish, and relates to the technical field of tundish coating preparation. The preparation method comprises the following steps: S1, preparing a first mixed solution from phosphoric acid and deionized water, and then adding beryllium oxide powder and a defoaming agent to obtain a beryllium oxide dispersion liquid; s2, the tundish subjected to sand blasting treatment is immersed in the beryllium oxide dispersion liquid to be subjected to coating treatment for 2-3 times; and S3, the coated tundish is roasted, and the tundish containing the beryllium oxide coating with the thickness ranging from 1.5 mm to 2.0 mm is obtained. According to the method, firstly, phosphoric acid serves as a binder to prepare beryllium oxide dispersion liquid, then the inner wall of the tundish which is low in price is coated with the beryllium oxide dispersion liquid for multiple times, and then roasting is conducted to obtain the tundish containing the beryllium oxide coating, wherein the tundish can resist thermal shock of metal beryllium melt and can guarantee the purity of prepared beryllium powder.
本发明公开了一种含氧化铍涂层中间包及其制备方法，涉及中间包涂层制备技术领域。所述制备方法包括：步骤S1，以磷酸和去离子水制备第一混合液，之后加入氧化铍粉末和消泡剂得到氧化铍分散液；步骤S2，将经喷砂处理后的中间包浸没于所述氧化铍分散液中进行2～3次的涂层处理；步骤S3，将经涂层后的中间包进行焙烧，得到含厚度为1.5～2.0mm氧化铍涂层的中间包。本发明首先以磷酸作为粘结剂制得氧化铍分散液，之后通过在价格低廉的中间包内壁多次涂覆氧化铍分散液后焙烧的方法得到一种既能抵抗金属铍熔液的热冲击，又能保证制得铍粉的纯度的含氧化铍涂层中间包。
