工业热处理设备中目前大量使用的电阻炉炉衬大多是由粘土砖、硅藻土砖等砌筑而成,炉体笨重、蓄热量多、散热损失大,因此耗电大生产率低。近年来很多使用单位在自己原有的电阻炉中采用了新型保温材料——耐火纤维,在节省电力、升温快、节省工时、降低生产成本等方面取得了明显效果。 Industrial heat treatment equipment used in most of the resistance furnace lining is mostly made of clay brick, diatomaceous earth brick masonry, furnace bulky, heat storage, heat loss, so the power consumption of large production rate is low. In recent years, many units used in their own resistance furnace with a new type of insulation material - refractory fiber, saving electricity, heating up fast, save time and reduce production costs and achieved remarkable results.
