Aluminum-carbon integral stopper rod and preparation method thereof
The invention particularly relates to an aluminum-carbon integral stopper rod and a preparation method thereof. The method comprises steps as follows: in percentage by mass, subjecting 30-40% of large-particle fused corundum (5-1mm), 20-30% of small-particle fused corundum (1-0.088 mm), 10-20% of activated aluminum oxide, 10-15% of carbon, 0-2% of an antioxidant, 2-5% of a binder and 5-10% of silicon waste to mixing, molding and carrying out heat treatment; and finally, in a carbon burying atmosphere, keeping the temperature at 1400-1600 DEG C for 4-6 hours to prepare the in-situ reinforced aluminum-carbon integral stopper rod material. The silicon carbide whiskers generated in situ can effectively enhance the mechanical and thermal shock resistance of the stopper rod. The special additiveis obtained by treating industrial waste, and is low in cost and simple in process. And the method has the possibility of being amplified to industrial production.
本发明具体涉及了一种铝碳质整体塞棒及其制备方法。具体制备方案为：按质量分数配料：30%~40%大颗粒电熔刚玉（5~1 mm），20%~30%小颗粒电熔刚玉（1~0.088 mm），10%~20%活性氧化铝，10%~15%碳素，0%~2%抗氧化剂，2%~5%粘结剂，5%~10%硅废料，混炼，成型，热处理。最后在埋碳气氛下，1400~1600℃保温4~6 h制成原位增强的铝碳质整体塞棒材料。原位生成的碳化硅晶须可有效增强塞棒的力学及抗热震性能。本发明的特殊添加是工业废料处理而来，成本低廉，工艺简单。具备放大到工业生产中的可能性。
