Steel ball is a commonly used grinding medium with the following characteristics:
1. High hardness: Grinding tool steel ball is usually made of high carbon chromium steel material, high hardness, can effectively grind hard materials.
2. Strong wear resistance: Due to the use of high hardness material, grinding tool steel ball has good wear resistance, can be used for a long time and is not easy to wear.
3. Good compression resistance: After special treatment, the steel ball of the grinding tool has high compression resistance, can withstand greater pressure, and is not easy to deformation or fracture.
4. Good grinding effect: The steel ball of the grinding tool has high grinding efficiency and grinding accuracy, which can quickly and evenly grind the surface of the object to achieve the required smoothness or accuracy.
5. Widely used: Grinding tool steel ball can be used for metal materials, ceramic materials, glass and other materials grinding processing, widely used in machining, electronic manufacturing, chemical industry and other fields.
It should be noted that the appropriate size and material need to be selected according to the specific situation during the use of the grinding tool steel ball to ensure the grinding effect and service life. In addition, pay attention to safety precautions during use to avoid damage to personnel and equipment

Zhejiang natural gas power station price is adjusted to 33.6%
A few days ago, several gas-fired power plants in Zhejiang received notifications about price hikes, as the cost of natural gas delivered to these facilities through gate stations increased sharply. Some gas companies raised their prices by as much as 33.6%, putting significant pressure on power generation companies. In response, some plants have started passing on these increased costs by raising their on-grid electricity prices, with some increases reaching up to 21.5%.
Industry experts believe that while the gate station price increase is substantial, the subsequent adjustment in on-grid tariffs reflects local government support for the natural gas industry. This move has helped ease the impact of the higher gas prices on power generation, potentially reducing losses more than expected. The development of the natural gas power sector could see a boost from this policy, which may also benefit listed companies involved in gas power equipment.
According to An Xun Sixiwang Energy, the gate station prices for gas-fired power plants in Zhejiang rose significantly starting July 10. For example, in Hangzhou, the price per party (including tax) went from 2.41 yuan to 3.22 yuan, marking a 33.6% increase. Prices varied slightly across different regions, with some plants seeing gate station prices rise to 3.28 yuan per party, though all increases exceeded 30%.
To mitigate the financial strain, the Zhejiang Provincial Government approved an increase in the on-grid tariff for gas-fired power plants to 0.904 yuan per kWh (including tax), up from 0.744 yuan per kWh, a 21.5% increase. This decision aims to help power plants manage rising costs and pass them on to consumers.
Dongdian B recently confirmed that the gate station price for natural gas supplied to its Xiaoshan Power Plant was adjusted to 3.22 yuan per cubic meter, up from 2.41 yuan, effective July 10. At the same time, the temporary on-grid tariff for the plant’s gas units was raised to 0.904 yuan per kWh, matching the new rate.
An analyst from An Xun Sixiwang Energy, Wang Ruiqi, noted that Zhejiang’s natural gas production has been operating at a loss, with limited capacity to meet demand, especially during peak times. He said the recent price adjustments are expected to keep the profitability of gas power generation relatively stable, though no formal subsidies have been announced yet.
Wang Ruiqi added that while the Zhejiang plan was anticipated, the speed and magnitude of the on-grid tariff increase caught many off guard. “The immediate response from the gas supply side was stronger than expected,†he said.
Beyond Zhejiang, other provinces like Guangdong are also considering similar gas price adjustments for power generation. Industry insiders suggest that Zhejiang’s approach may serve as a model for other regions. However, the nationwide impact remains uncertain until more details are released.
Another analyst, Zhuo Chuang Wang Xiaokun, noted that while price adjustments are being implemented across various regions, most are still in the planning stages. Industrial gas users, such as those in the fertilizer sector, have seen more immediate changes, while LNG ex-factory prices are expected to rise significantly. However, many factories have yet to announce specific pricing, with actual implementation likely to be delayed until August.
Despite the challenges, industry insiders believe that the gate station price hike could dampen enthusiasm in the already struggling natural gas power generation sector. However, the swift on-grid tariff adjustment shows local governments are willing to support the industry, potentially easing the burden more than anticipated. This could create a favorable environment for growth and benefit related listed companies in the long run.
