Description

一种电磁感应内加热可抽屉式出渣的镁真空还原炉
本申请要求以下中国专利申请的优先权，其全部内容通过引用结合在本申请中。中国申请号：2022216463200，中国申请日：2022年06月29日，发明创造名称：一种电磁感应内加热可抽屉式出渣的镁真空还原炉。
技术领域
本发明涉及镁金属冶炼工艺技术领域，尤其是一种电磁感应内加热可抽屉式出渣的镁真空还原炉。
背景技术
在现代社会，金属镁由于其优异的性能和大的储存量，获得了非常广泛的应用。我国金属镁的生产，绝大多数使用的是一个意大利人发明的皮江法，也就是通过加热耐热钢制造的还原罐中的原料，再加上对还原罐的抽真空，在高达1200摄氏度的时候，使原料中的金属镁成为镁蒸气，然后凝结结晶在外面有冷却水的凝结室里，从而实现从矿石原料到金属镁的冶炼过程。皮江法炼镁包括白云石煅烧、粉磨与压球、真空热还原等过程，对于皮江法来说，其工艺流程和设备较简单、建厂投资少、生产规模灵活、成品镁的纯度高等特点，其炉体小、建造容易、技术难度小，并且可以直接利用资源丰富的白云石作为原料，所以在我国得到了快速的发展。
目前在使用皮江法对还原炉中的镁进行还原后，需要操作工人使用工具在还原炉内扒出废渣，在清渣的过程中，存在粉尘的飞扬，另外，镁渣和还原炉的热辐射也比较严重，这导致工人劳动环境较为恶劣，不符合环保理念，采用人工清渣无法实现自动化生产，此外，目前对还原炉中镁铝球团的加热方式多采用火焰加热结构，加热效率低、能源利用率低，不便对加热过程进行控制，严重降低了镁生产的效率，为此急需一种电磁感应内加热可抽屉式出渣的镁真空还原炉，来解决上述出现的问题。
