研究了用远红外线干燥氧化铀凝胶球的各种影响因素，其中包括湿球（φ１．２ｍｍ）的铺放强度。空气的对流与增湿，温控程序等。目的是获得无破裂的干球，以奠定热处理的良好基础。结果表明：远红外箱内的热空气应当对流与增湿。在温控程序中对６Ｏ℃的恒温时间应≥２．５ｈ，在该条件下，湿球的铺放强度能达到３．８ｋｇ／ｍ２。还讨论了凝胶结构、脱水及干球破裂的机理。 Various factors influencing the uranium oxide gel balls with far infrared radiation were studied, including the laying strength of wet ball (φ1.2mm). Air convection and humidification, temperature control procedures. The goal is to get a dry ball without rupture to lay a good foundation for heat treatment. The results show that the hot air in the far-infrared box should be convected and humidified. In the temperature control program of 6O ℃ constant temperature time should be ≥ 2.5h, under the conditions of wet ball laying strength can reach 3.8kg / m2. Also discussed the gel structure, dehydration and dry-bulb rupture mechanism.
