Description

用于镁合金熔炼的低能耗电阻炉
技术领域
本发明涉及一种用于镁合金熔炼的低能耗电阻炉。
背景技术
随着社会的发展，能源匮乏，环境污染越来越凸显，越来越受到人们的关注，以前很多企业以消耗大量的能源为代价来获得高昂的利润，然而现在，“节能降耗”逐渐成为企业增强竞争力，降低成本的重要途径，也是企业响应国家政策，造福后代的重要体现。在镁合金冶炼行业中，寻求低能耗的电阻炉，也是安全生产的重要途径。
发明内容
本发明的目的是提供一种用于镁合金熔炼的低能耗电阻炉，结构简单，操作方便，使用安全，保温绝热性能好，避免了熔炼过程中炉丝因温度过高导致的炉丝熔断，热能利用率高于80％，使镁合金的熔炼成本大大降低，节约成本。
本发明所述的一种用于镁合金熔炼的低能耗电阻炉，包括外层陶瓷珠隔热涂层和内层陶瓷珠隔热涂层，外层陶瓷珠隔热涂层和内层陶瓷珠隔热涂层之间设置陶瓷纤维模块；内层陶瓷珠隔热涂层内侧设置炉丝。
内层和外层陶瓷珠隔热涂层均由纳米氧化锆、纳米a氧化铝、纳米氧化钛、纳米氧化铈、空心陶瓷珠组成。
炉丝为扁平的带状炉丝。
炉衬采用陶瓷纤维模块，依据所需炉体尺寸定做，整体性好，有较强的绝热性能。
陶瓷纤维模块的两面涂陶瓷珠隔热涂层，进一步加强炉体的保温绝热性能。
将电阻丝制作为扁平的带状炉丝，增大炉丝的表面积，其表面能明显加大，热利用率大大增加；同时避免了熔炼过程中炉丝因温度过高导致的炉丝熔断。
在电阻炉上安装坩锅后，用陶瓷纤维模块填充炉体与坩锅的上缘间隙，使电阻炉热能利用率高于80％。
本发明所用的原料均为市售。
与现有技术相比，本发明具有以下有益效果：
本发明结构简单，操作方便，使用安全，保温绝热性能好，避免了熔炼过程中炉丝因温度过高导致的炉丝熔断，热能利用率高于80％，使镁合金的熔炼成本大大降低，节约成本。
