After the coal price fell for 6 weeks, it began to increase Shenhua Group's weekly coal price.
In the current period, the average price of thermal coal around the Bohai Sea rose slightly by 1 yuan per tonne, or 0.13%. Excluding the 5,000 kcal thermal coal price at Qinhuangdao Port, the price of thermal coal was lowered by RMB 5/ton, and the remaining coal prices remained unchanged. The Qinhuangdao Port thermal coal prices remained stable overall.
Industry analysts pointed out that this year's coal prices tend to oscillate upward overall. The further westward shift in the focus of coal production leads to an increase in transportation costs, which will inevitably support coal prices. The loose monetary policies in major advanced economies have led to an increase in the prices of bulk commodities in the international market, increasing input pressure on domestic coal prices, and controlling the market power of coal companies. The continuous improvement of coal prices has made it more and more vulnerable to falling.

The following are some key points for purchasing a hydraulic cylinder sealing kit:
1. Determine the model and specification of the hydraulic cylinder: The size and model of the hydraulic cylinder sealing kit must be completely matched with the hydraulic cylinder, otherwise it may cause poor sealing or damage to the sealing components.
2. Choose appropriate sealing materials: The sealing materials for the hydraulic cylinder sealing kit should be selected based on factors such as the type of hydraulic oil, temperature, pressure, etc. The commonly used sealing materials are fluororubber, Butyl rubber, polyurethane, etc.
