采用国产立式氢气中频感应烧结炉进行钨板坯烧结，研究了钨压制坯的装炉方式、装炉量以及高温段保温时间等工艺参数对钨板坯质量的影响。研究结果表明：（1）钨压制坯烧结过程中，装炉方式的变化会影响板坯热传递效率和温度均匀性，根据设备特点选择恰当的装炉方式，确保烧结晶粒和密度的均匀性；（2）装炉重量是影响钨板坯烧结质量的重要因素，在相同烧结设备和烧结工艺条件下，装炉量越大，烧结后钨板坯密度越低，晶粒度越大；（3）高温烧结阶段，随着保温时间的延长，钨板坯致密化过程持续进行，其密度增加，晶粒度减小。

The Vertical hydrogen IF induction sintering furnace was applied for sintering tungsten slab. The effects of processing parameters, including installation way, installed furnace capacity and high-temperature section holding time on the quality of tungsten slab were tested. The results show that different furnace installation technologies affect the heat transfer efficiency and temperature uniformity during the sintered process; proper furnace installation guarantees the uniformity of sintered grains and density. The installed furnace capacity, being proportional to the grain size of sintered tungsten slab, is inverse proportional to the product density under the same sintering conditions and sintering equipments. With the extended holding time in its high temperature sintering stage, tungsten slab densification process continues with increased density and decreased grain sizes.
