In May, the power supply situation in Anhui Province was suddenly severe, and the chemical companies in the province that had been suffering from power shortage for many years had accumulated practical experience in responding to the “electricity shortage.” At present, they have implemented refined power management. To reduce losses and ensure efficiency.

In mid-May, Hefei began to curtail power for some companies. Zhongyan Anhui Hong Sifang Co., Ltd. is one of the industrial pillars of the city and is also a large consumer of electricity. The reporter learned that in mid-March, due to market reasons, the company had stopped the maintenance of some of the devices, and the electricity load also dropped by about 13,000 kilowatts. Once the production is resumed, power cuts will have a greater impact on the company.

In early May, the company conducted a complete overhaul of the steam turbine of the Thermal Power Plant No. 1. The two generating units of the Thermal Power Plant No. 2 were under the unified command of the production dispatch center to control the power generation load according to the conditions of the use of steam. Accelerated the progress of overhauling some of the generator sets and ensured that they were put into use before the peak of electricity usage. While optimizing the operation of the equipment, the company adjusted the equipment operation time, and under the premise of guaranteeing full production of some products, it adjusted the working hours of the auxiliary positions and responded to the current power-restricting situation.

Before the peak of electricity supply, Luzhou City has already implemented the peak load limitation and power cuts for local companies such as Samsung Chemicals Group in advance, which has caused a certain impact on the production of the company. Samsung Chemical Co., Ltd. has established a coordination power group and designated the production vice president to be responsible for coordinating power consumption. The production scheduling communicates with the local power supply bureau in a timely manner, actively strives for the power load, and minimizes the impact. At the same time, make preparations for power cuts every day, and arrange production and overhaul work in an integrated manner in advance. In order to improve the production and utilization of electricity, the company made detailed adjustments to the production and maintenance work during the 19 to 21-hour power cut every day, and took full advantage of SAMSUNG's self-generating power to adjust the power generation at a reasonable time during the peak time of electricity consumption. Load, optimize the power generation process.

The management of the company is outstanding. The first priority is to purchase raw coal for thermal power to ensure that the generator sets can operate at maximum load. A comprehensive inspection of the company's motor-pumped motor, a reasonable adjustment of the process load, completely put an end to the "big cow pull cart" phenomenon. For high-energy-consuming motors, they have deactivated one batch, eliminated one batch, and repaired one batch to optimize the equipment structure.

In addition, they are also actively grasping the product market, fine-tuning the product structure, and calculating the profitability points of products based on the price of each product every day. With the current rise in urea prices, they timely compressed methanol, ammonia production, increase the production of urea, to maximize the interests of enterprises.

Entering May, industrial enterprises in Anqing have an average power limit of 4 to 5 hours per day. Due to the intermittent production of the cracking furnace and the shutdown of the raw materials, the Shuguang Chemical Group needs to reheat up after the raw materials are cooled, and the power consumption per unit product has increased, which has reduced the output. The Group actively took measures to comply with the requirements of the emergency plan. During the limited time period, the production equipment was reduced by approximately 20%. The company’s main responsible person and technical staff were coordinated and coordinated, according to the production situation to adjust the process parameters at any time, and take reasonable measures to ensure the production of the device. Safety.

In the face of the severe power situation, Wuhu Ronghui Chemical Co., Ltd. has focused on management to ensure the safe and stable operation of production and installations. In addition, the company combined product market information, paid close attention to the inventory of finished products and intermediate products, enhanced the scheduling of production load and production process control, and tracked the operation of high-power electrical equipment and high-energy-consuming process equipment in a timely manner to strengthen safety production. And energy saving management. Externally, it strictly implements the “Orderly Use of Electricity Agreement” signed by the company and the power supply department, avoiding peaks in a timely manner on the premise of ensuring production safety and order, adjusting the load, and maintaining close contact with the power supply department.

In addition, the reporter also learned during the interview that at present, some large chemical companies in Anhui Province have received active coordination and strong guarantees from the local government in terms of electricity consumption. If Huaihua Group took full advantage of local coal and electricity resources, Tonghua Group launched power projects.

358 Fence

The 358 fence is a dense mesh guardrail mesh. Due to its unique mesh size, it is generally used for security protection in airports, prisons and other places.
It can also called Security Anti-Climb 358 Fence,Anti Climb Prison 358 Security Fence,Barbed Wire 358 Fence

The origin of the name of the 358 fence is inseparable from its mesh size:

"3" corresponds to a 3-inch long hole, which is 76.2mm;

"5" corresponds to a short hole of 0.5 inches, which is 12.7mm;

"8" corresponds to the diameter of No. 8 iron wire, which is 4.0mm.

So to sum up, the 358 guardrail is a protective mesh with a wire diameter of 4.0mm and a mesh of 76.2*12.7mm. Because the mesh is extremely small, the mesh of the entire mesh looks dense, so it can sometimes be called It is dense mesh.

It is very suitable to be used as a fence net for safety protection. Because of the special mesh size of the 358 fence, it is difficult for ordinary climbing tools or fingers to climb, and it is difficult to cut it even with the help of large scissors, so if you It is used as a fence net for safety protection, so there is no problem in choosing it.
