How To Make High Quality And High Yield Silicon Metal in Smelting Furnace

In addition to requiring good furnace parameters, excellent raw materials, and reasonable proportions, the quality of operating methods is a very important factor. Reasonable feeding methods play a leading role in the structure of the material layer, the stability of the electrode in the furnace, and the full utilization of heat energy. In production, feeding and ramming are combined. According to the different situations and characteristics of the smelting process, timely completion of feeding and ramming operations is necessary. In order to maintain good ventilation inside the furnace, eye piercing and furnace ramming are necessary. The small ramming furnace is carried out according to the furnace condition, while the large ramming furnace is generally carried out once every hour. The ramming furnace should be almost transparent, and the rammed blocks should be pushed towards the furnace core. During the ramming process, new materials should not be added while ramming the furnace. It is not advisable to use one electrode area and one electrode area for furnace ramming. It is necessary to concentrate and unify the furnace ramming and feeding in order to maintain a high melting temperature. The most important factor to stabilize furnace operation is to maintain a constant temperature distribution in the charge layer. If the temperature distribution in the furnace is damaged, the furnace operation will be seriously disturbed. The particle size and uniformity of the furnace charge during production, charging and discharging, and the treatment of the furnace charge surface will affect the electrode movement. Excessive electrode movement and strong ramming will make the furnace operation unstable.
