Li trè enpòtan pou detèmine rezonab debaz la endiksyon fonn gwo founo dife (furnace wall thickness). Some foundries are pursuing the life of furnace wall thickness one-sidedly, pursuing the “furnace age award”, and increasing the thickness of the crucible (furnace wall thickness) unlimitedly, which leads to an increase in energy consumption. In fact, increasing the thickness of the furnace wall can indeed extend the life of the furnace wall thickness, but it reduces the melting rate (prolongs the molten iron melting time) and increases the continuous heat loss. In order to extend the life of the furnace wall thickness when a 15-ton industrial frequency furnace was used in a domestic foundry, the furnace wall thickness was increased from the prescribed 170mm to 230mm. The life of the furnace wall thickness did increase a lot, but the electricity consumption per ton of molten iron was lower. As high as 1500KW·h, the gain is not worth the loss. Later, the factory had to restore the thickness of the furnace wall to 170mm, reducing power consumption by almost half.
