我厂原来的电极盐炉是老式的插入式电极盐浴炉,有高、中温各一台,由于升温速度慢,耗电大等缺点,我们曾先后改装成顶埋入式和侧埋入式电极盐浴炉。其炉内坩埚采用高铝砖加“701”泥浆砌筑而成。生产中,我们发现此种坩埚的砌筑方法存在如下缺点:筑炉时工作繁重,工期长,成本高;使用中砖的砌缝易开裂,漏盐严重,寿命短等。因此我们决定改革此 The original electrode salt furnace in our factory is an old-style plug-in electrode salt bath furnace with high and medium temperature each. Due to the shortcomings of slow heating rate and large power consumption, we have successively transformed into the top-buried and side-buried Electrode salt bath furnace. The furnace crucible with high alumina brick plus “701” mud masonry. In production, we found that the masonry method of this kind of crucible has the following disadvantages: heavy work, long construction period and high cost when building a furnace; easy to crack, leaky salt, short life and the like of the built-up bricks in use. So we decided to reform this
