In August, domestic calcium carbide market prices rebounded. In the Inner Mongolia Autonomous Region, the price of calcium carbide in the domestic market was first increased by 100 yuan per ton, reaching 1,950 to 2,000 yuan per ton, and the price in the northwest region began to rise. The factory price of calcium carbide reached 2,000 to 2,050 yuan per ton. Affected by this, the market price of calcium carbide in Hebei, Henan, Hunan, and Hubei also rose by 100 yuan per ton, while the market price in the northeast was relatively stable. At present, the rise in calcium carbide prices has spread to eastern and southern China.
The main reasons for the increase in domestic calcium carbide market prices are the sharp rise in energy prices such as crude oil, coal, and electricity. At present, the international crude oil market prices are at a high level, and there is a further upward trend; the domestic coal market due to frequent production accidents, the state requires more than 7,000 coal mines to stop production, carry out safety inspections, so that coal production is affected to some extent, despite the current domestic coal prices It has declined, but market prices are still consolidating at higher prices; power shortages have led to power cuts, which have affected the production of calcium carbide, and the rise in logistics costs has prompted the market price of calcium carbide to further increase. At present, the trend of rising prices in the calcium carbide market has further developed because the existing inventory of calcium carbide manufacturers is decreasing, and the operating rate of calcium carbide production plants is generally at a relatively low level of 50% to 60%.
The current domestic mainstream price of calcium carbide is 2100 ~ 2500 yuan / ton. Among them, Inner Mongolia is about 2,100 yuan/ton, in the northwest region is about 2,200 yuan/ton, in North China, the mainstream price is about 2,350 yuan/ton, in the Northeast, the mainstream price is about 2,500 yuan/ton, and in Central China, the mainstream price is 2550 yuan/year. About tons. The mainstream prices in East China and South China are around 2,600 yuan/ton.
Although the domestic calcium carbide market conditions have improved in September, and calcium carbide manufacturers are in a more favorable market environment, the pressure on supply and demand in the market is still relatively large.
