CNC busbar servo bending machine is the computer-controlled equipment dedicated for busbar bending, performing various bending operations through the coordination of X-axis and Y-axis movements, assisted with manual feeding. The selection of different dies can complete the plane bending, side bending and other processes of busbar. The machine can be used in combination with GJ3D software, and is able to accurately calculate the spread length of the bend. As to the frequently bent workpiece, it can automatically find the bending order to achieve programming automation, simulate the bending order to place busbar and avoid errors in determining the bending positions.

From the survey conducted by the reporters, those chemical fertilizer companies adopting new coal gasification technologies and using bituminous coal, pulverized coal, lignite, etc., are all effective, but they only use anthracite as raw materials and adopt fixed-layer intermittent gasification technology ( UGI)'s fertilizer companies have experienced rising costs due to rising coal prices and difficult survival. Therefore, companies that use anthracite as their raw materials can only have a way out if they are determined to change the route of raw materials, and such adjustments should be made sooner rather than later.
It is understood that since the beginning of this year, the prices of bituminous coal, pulverized coal, and lignite are only about half of the anthracite price, and sometimes even lower. With new technologies, the competitiveness of fertilizer companies that can use these coal types is more and more fully reflected. When companies that use anthracite as raw materials stop production by 30%, these companies can also guarantee certain benefits.
The reporter learned from Shanxi Tianji Coal Chemical Group Co., Ltd. that the coal gasification technology of the ammonia plant of the plant was introduced from the German Luqi company and that after years of digestion and innovation, it has pioneered the “Lurgi gasification lean lean coal†in the world. And "Lurgi furnace gas production of synthetic ammonia" technology, so that the company can use lean coal as raw material. Compared with high-quality anthracite, tons of ammonia can save about 500 yuan.
Shandong Luxi Chemical Group Co., Ltd. stated that their original coal gasifiers use a fixed bed process and lack cost advantages. After their newly built 200,000 tons of synthetic ammonia and 300,000 tons of urea plants were equipped with aerospace furnaces, due to the availability of multiple coal types, the cost of raw coal decreased by nearly 50%, which eased the company’s cost pressures.
Shandong Hualu Hengsheng Chemical Industry Co., Ltd. relies on its own four burners to dispose of coal-water slurry pressure gasification technology, using lower-priced bituminous coal as raw materials, and the tons of ammonia cost about 600 yuan more than using anthracite coal. By the third quarter of this year, the company has realized a net profit of 331 million yuan, and it is expected to achieve a net profit of 450 million yuan in the whole year.
Jiangsu Linggu Chemical Co., Ltd. adopts multi-nozzle coal-water slurry coal gasification technology to produce 450,000 tons of synthetic ammonia and 800,000 tons of urea technological transformation capacity expansion projects. It can use bituminous coal as raw materials, reducing the cost of urea by 30%, and save years. Standard coal is 91,300 tons and electricity is saved at 300 million kwh.
Yunnan Xiehua Group Co., Ltd. has successfully developed coal crushing slag gasification technology with independent intellectual property rights, using local lignite as raw material, and tons of synthetic ammonia to reduce the cost of about 450 yuan.
In addition, Shaanxi Weihe Coal Chemical Group Co., Ltd., Heilongjiang Haolianghe Chemical Co., Ltd., Anhui Huaihua Group Co., Ltd., Guangxi Liuzhou Chemical Industry Co., Ltd., Yunnan Tianan Chemical Co., Ltd., and Hubei Shuanghuan Technology Co., Ltd., also implemented The technological transformation of raw coal has a significant cost advantage this year, and the plant loading rate has been high, maintaining a good profit.
However, the person in charge of the technology of Shanxi Fengxi Huarui Coal Chemical Industry Co., Ltd. told the reporter that the current domestic fertilizer enterprises adopting the new coal gasification technology account for only 5% of the total number of chemical fertilizer enterprises, and enterprises using fixed-layer intermittent gasification technology (UGI) Still the vast majority, there are more than 4,000 gasifiers need to be transformed.
The person in charge reminded the company that although the fixed-bed intermittent gasification process has also seen new development in recent years, the comprehensive energy consumption is still 20% to 30% higher than that of the advanced coal gasification technology, and the raw coal used has not changed. Now the state has made it clear. The new process is forbidden. Starting from a long-term perspective, the process itself is constrained by raw materials, technology, and environmental issues, and it will eventually be replaced by new coal gasification technologies. Although China’s national conditions have determined that this process may take 10 years or more, the new project will no longer allow the ban on the fixed-bed intermittent gasifier and it has become an early warning. Enterprises should take the initiative to adjust the raw coal route, adopt clean coal gasification and energy cascade utilization technology as soon as possible, rapidly realize diversification of raw coal, and meet the challenges of price reform of resource products.
Since the beginning of this year, the price of anthracite has been at a high level, and the average annual factory price is above RMB 1,000/ton. In addition to Shanxi Province, anthracite prices in other anthracite production bases such as Inner Mongolia, Henan, Anhui, and Ningxia are also rising. In addition, due to the influence of coal enterprise reorganization and Spring Festival holiday, the future domestic coal supply will appear short-term tense situation, coupled with the increase in coal mining industry's machine extraction rate, the lump coal rate will be reduced to 20% and the winter fat coal capacity will be tight. From now to April next year The price of anthracite coal will generally rise.
