In the context of downward fluctuation of the surrounding market during last weekend, the calcium carbide enterprises have suffered sales difficulties in Ningxia, sone of whom had to further lower their ex-factory price, making it difficult to stop the decline of the average transaction price. At this stage, while the mainstream ex-factory price of local first-class carbide is 3350-3450 yuan/ton, a lower price is about 3300 yuan/ton. Based on the analysis of the supply and demand relationship in the current domestic carbide market, although the excessive supply has been alleviated with the continuous decline of prices, it is not easy for the carbide market to pick up.
