At present, as the calcium carbide market in Wuhai, Inner Mongolia is steadily rising, the average transaction price continues to pick up. Although these carbide manufacturers that previously stopped production in Northwest China are gradually resuming production, the supply of calcium carbide goods is still tight in some areas due to the high operating load of surrounding chlor-alkali plants. In addition, the earthquake has affected Gansu and Ningxia regions, causing a basic stagnation in the transportation of calcium carbide and further resulting in a decrease in the supply of goods in the surrounding markets.
