Abstract

本实用新型是电阻感应复合加热炉，由外层的耐火保温材料、电阻加热元件、加热器皿组成，所述的电阻加热元件采用螺旋状态环在加热器皿四周，所述的电阻加热元件采用石墨棒、硅碳棒、硅钼棒或高电阻做成环状。以往的加热炉一般采用单独的电阻加热或者是中频感应加热两种独立的加热方式。本实用新型是电阻感应复合加热，当通入高频、中频电源的时候，电阻本身开始加热，而且中频电源通入电阻内形成感应电流，进行感应加热，因此在真空或者气体保护的状态下除了本身的电阻圈发热，还存在通中频、高频电源的电阻感应加热，因而形成电阻感应复合加热装置，所得的热效率高，在很多行业将被广泛应用。

Description

电阻感应复合加热炉
技术领域
本实用新型涉及一种电阻感应复合加热炉，主要用于各种金属的熔炼、保温，以及矿物质加工、精炼等过程的反应制备。 
背景技术
在加热炉领域，以往的加热炉通常使用气体燃料、重油或粉煤，有的烧块煤，此种加热炉使用电耗量大加热效果一般。现在常用的中频加热炉是一种将工频50HZ交流电转变为中频(300HZ以上至1000HZ)的电源装置，把三相工频交流电，整流后变成直流电，再把直流电变为可调节的中频电流，在感应线圈中形成感应电流，该加热方式升温速度快，材料利用率可达95％。由于该加热方式加热均匀，芯表温差极小，同时应用温控系统可实现对温度的精确控制提高产品质量和合格率，但是该种加热炉制造成本高，不能大面积普及。 
本实用新型是结合上述两种加热方式，利用自身加热和感应加热形成的一种复合加热炉，复合加热炉加热装置具有体积小，重量轻、效率高、成本低、热加工质量优及有利环境等优点，是新一代的复合加热设备。 
发明内容
本实用新型的目的是提供一种电阻感应复合加热炉。 
本实用新型要解决的技术问题是通过以下技术方案来实现的一种电阻感应复合加热炉，其特征在于：由外层的耐火保温材料、电阻加热元件、加热器皿组成，电阻加热元件采用螺旋状态环在加热器皿四周，该种电阻加热元件多采用石墨棒、硅碳棒、硅钼棒或其他高电阻做成环状。本实用新型主要是在通入中频、高频电源的时候，电阻加热元件本身作为加热元件，对物料进行加热，同时产生感应电流，进行电阻感应加热，从而形成电阻自身加热，电阻感应加热的电阻复合加热炉。 
本实用新型优点是： 
1.采用电阻加热主要是采用一些可以自身加热的元件，如石墨棒、硅碳棒、硅钼棒等做为电阻加热元件，这些元件成本低，加热效率高。 
2.通以高频、中频电源时候，电阻加热元件本身加热同时形成感应电流进行感应加热加热，从而形成电阻感应复合加热炉，双重加热，使得加热效率更高。 
3.在真空或者气体保护的状态下运行，因此可以克服各类电阻被氧化的弊端。
