改进智能高温高效节能电炉及耐火材料

Improving the Intelligent High-Temperature and High-Efficiency Furnace and Refractories

为了解决电炉工作时耗能高的问题,对我所自行研制的智能高温电炉做进一步改进。改进后的电炉选用氧化铝纤维耐火材料作为炉材,以二硅化钼作发热元件,选用了以工业PC为核心的电流反馈系统作电气控制。经过有关部门测试,其性能指标高于JB4311.7-91标准。能耗低于普通电炉的50%,工作省时,工作效率高于普通电炉5倍以上,长期工作温度1650℃,最高使用温度为1700℃,耐急冷急热性好,寿命为普通电炉的3倍,正常工作时炉体表面温度低,工作环境好。

In order to reduce the energy consumption, we improved the in-house developed high-temperature furnace by selection of the EAF alumina refractory fiber as the furnace material, MoSi2 as the heating elements, and PC as the core of the current feedback control system. The improved performance was higher than the JB4311.7-91 standards, with the electric energy consumption less than 50% of the ordinary furnace. It can save time, works more efficiently, and be operated long-term at the temperature high to 1650 ℃ with the maximum service temperature of 1700 ℃. It also can be rapid heated and cooled, its service life is three times that of ordinary EAF and it has low temperatures on surface of the furnace.
