SEALING RING AND PREPARATION METHOD THEREFOR |
摘要 |
<p>A sealing ring, comprising by weight proportion: 80%-85% aluminum, 10%-15% titanium, 0.1%-1% iron filings, 4%-4.9% potassium aluminum fluoride. Also disclosed is a preparation method comprising the following steps: A: melting the aluminum in a frequency induction furnace, adding thereto the potassium aluminum fluoride, melting same, and stirring to uniformity; B: adding to the mixture titanium filings or titanium sponge, then the iron filings, then at a temperature between 800°C and 1200°C causing the mixture to achieve total fusion, stirring to uniformity and allowing to stand; C: removing surface-floating impurities; D: casting into shaping molds to obtain the sealing rings. The softening points and melting points of the present sealing rings can be regulated and the rings can be used in a variety of reactors and distillers, ensuring smooth performance in high-pressure production processes and resolving pressure-resistance problems of sealing rings associated with high temperature conditions in reactors and distillers.</p> |
