【技术实现步骤摘要】
硬质合金脱蜡烧结炉
本技术涉及硬质合金制造设备领域,具体为一种硬质合金脱蜡烧结炉。
技术介绍
在硬质合金制品生产的压制成型中都要掺石蜡成型剂,但是,硬质合金产品烧结前必须先排除成型剂(即脱蜡),通常采用两种模式完成成型剂的排除,第一种为间歇式,即先用特定专用设备装置在600-8000C温度和氢气保护气氛下完成石蜡成型剂的脱除,随后产品冷却、再转移至烧结炉中完成烧结。第二种为连续一体式,即在专用脱蜡烧结设备中完成产品的成型剂脱除与烧结过程,成型剂脱除阶段采用负压方式,气氛介质为氮气或氢气。目前,在顶锤、轧辊等大制品的的大批量生产中多采用间歇式,但间歇式脱蜡产品“碳”量控制范围波动大,稳定性差,控制精度低。而采用连续一体的负压方式脱蜡,脱除石蜡效率低,产品碳量可控程度差。
