Introduction to the improvement method of submerged arc furnace lining performance!
Submerged arc furnace has always been the main product of yunengde. We are very familiar with the knowledge of various aspects such as the performance of submerged arc furnace. Today, we should introduce to you the relevant introduction of the improvement method of submerged arc furnace lining performance according to your needs!
At present, the capacity of submerged arc furnace is increasing, generally 20000 KVA, more than 100000. However, the lining masonry technology continues the traditional technology of small capacity kiln in the past, and has not been greatly improved. This leads to frequent early damage and scrapping accidents of submerged arc furnace lining, especially ferroalloy submerged arc furnace lining, which has caused huge economic losses to enterprises and hindered the development of submerged arc furnace technology. According to the author's understanding, there are three methods of furnace lining:
1. Carbon brick wide joint method: leave a gap of about 50mm between carbon bricks, fill it with cold ramming paste of self baking carbon material, and then lay a layer of Cold ramming paste of about 10cm on it;
2. Carbon brick seamless method: there is no gap between carbon bricks. During masonry, each carbon brick is tightly bonded together with a jack, and then a layer of Cold ramming paste of about 10cm is paved on it, which is the most commonly used method at present;
3. Integral tamping method: use cold tamping paste instead of carbon brick for integral furnace pouring.
Well, to sum up, this is the introduction to the performance improvement methods of submerged arc furnace lining. For more details, please refer to the official website: http://flpx.com.cn/
