Description
技术领域
本发明涉及熔炉发热体材料技术领域，尤其涉及一种电磁熔炉发热体用复合材料。
背景技术
电磁感应工业炉是在感应炉中的感应线圈交变电磁场作用下，发热体内部产生涡流，发热体发热，发热体将热量传输至金属物，从而达到加热或着熔化的效果。
现有的发热体在实际应用中，由于发热体杂质较多，电阻较大，其发热效率非常低，且由于电磁熔炉一般是对金属进行熔融，发热体温度需要特别高，在高温下，现有的发热体在发热的同时，由于不能耐高温，自身也在熔融，强度也不高，造成其使用寿命大大缩短，熔融的金属物也混入杂质。
发明内容
有鉴于此，本发明提供了一种电磁熔炉发热体用复合材料。
一种电磁熔炉发热体用复合材料，按质量份数其原料组份包括：石墨36-44份，碳化硅28-36份，二氧化硅14-22份，硅酸铝4-9份，氧化铝15-25份，烧结剂8-15份。
优选地，按质量份数其原料组份包括：石墨38-41份，碳化硅31-34份，二氧化硅16-21份，硅酸铝5-8份，氧化铝17-23份，烧结剂9-13份。
优选地，按质量份数其原料组份包括：石墨40份，碳化硅32份，二氧化硅18份，硅酸铝7份，氧化铝21份，烧结剂11份。
优选地，所述石墨为稳晶质石墨。
优选地，所述二氧化硅为纳米二氧化硅。
优选地，所述烧结剂为硼酸与硅酸盐水泥中的一种或两种。
优选地，所述烧结剂为硼酸。
本发明的有益效果在于：电磁熔炉发热体用复合材料，将复合材料制成电磁熔炉的发热体，主要以石墨和碳化硅为主体原料，由于石墨和碳化硅的电阻随温度的升高阻值减小，在高温下，其发热效率越高；且与其他材料形成无机复合材料，其强度高，耐高温，使得其使用寿命大大延长。

根据性能测试表中的数据可以看出，实施例1-5的复合材料，其抗折强度可以达到45Mpa，常温下，其电阻率约为7×10-6，但是在高温1000℃下，其电阻率可以达到0.32×10-6，且耐火度平均可以达到1750℃。
以上是对本发明所提供的具体实施例。
说明书对本发明进行了详细的介绍，本文中应用了具体个例对本发明的结构原理及实施方式进行了阐述，以上实施例只是用于帮助理解本发明的方法及其核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本发明的限制。
