1600℃高温箱式炉是以二硅化钼为发热元件的高温电阻炉。二硅化钼棒在氧化气氛下性能稳定,使用温度可达1700℃。因此这种高温箱式炉广泛应用在冶金、热处理、硅酸盐等工业中。 我国现有这种高温炉定型产品只有实验室电炉,最大功率为10瓩,炉膛尺寸仅400×200×150mm。由于炉膛温度高,所以对炉用耐火材料的材质与形式要求较高,过去一般采用重质刚玉砖。重质刚玉砖容重大,导热系数大,热膨胀系数也大,热稳定性差,因此即使用作10KW以下的小炉子炉顶也经常发生开裂,甚至有塌落现象,且蓄热大,散热损失也大。因此,在我组新设计制造的一台50瓩高温箱式
1600 ℃ high temperature box furnace is molybdenum disilicide heating element for high temperature resistance furnace. The molybdenum disilicide rod has stable performance under oxidizing atmosphere and can be used up to 1700 ℃. Therefore, this high temperature box furnace is widely used in metallurgy, heat treatment, silicate and other industries. China’s existing such high-temperature furnace stereotypes only laboratory electric furnace, the maximum power of 10 瓩, the hearth size is only 400 × 200 × 150mm. As the furnace temperature is high, so the refractory material on the furnace and the form of higher requirements in the past generally used heavy corundum brick. Heavy corundum brick capacity, thermal conductivity, thermal expansion coefficient is also large, poor thermal stability, so even if used as a small furnace below 10KW furnace roof cracking often occur, and even collapse phenomenon, and a large heat storage, heat loss is also Big. Therefore, in our new design and manufacture of a 50 瓩 high temperature box
