Aluminum profiles are an important part of the conductors of the sliding wires. The fluctuation of the cost of raw materials directly affects the price of the trolley wires.
Today, the domestic spot aluminum price has fallen slightly. The mainstream transaction price in the market is in the range of 15340-15450 yuan/ton. With the downward shift of the market turnover and the sufficient supply of goods in the market, the enthusiasm of the traders is acceptable, but the downstream enterprises Purchasing was cautious, and the transaction was mainly based on demand, and the overall market conditions did not change significantly.
The spot transaction price in Shanghai is in the range of 15430-15450 yuan / ton. Wuxi spot transaction price is in the range of 15410-15430 yuan / ton. The spot transaction price in Hangzhou is in the range of 15430-15450 yuan / ton. The spot transaction price in Guangdong is in the range of 15430-15440 yuan / ton. Shenyang spot transaction price is in the range of 15440-15450 yuan / ton.
It is believed that as the global economy recovers slowly, especially the demand for construction and real estate and industrial machinery industries will continue to increase, the price of aluminum profiles is expected to increase further.
Why is the sliding wire selected as an aluminum profile instead of pure aluminum as a conductor?
Why not choose pure aluminum as the conductor of the sliding wire and choose the aluminum profile as the conductor of the sliding wire. Let us explain it today.
The higher the purity, the better the corrosion resistance, mainly because pure aluminum reacts with oxygen in the air to produce a thin and dense natural oxide film on the aluminum surface, which is faster and thicker than other metal oxide films. This prevents further corrosion of harmful gases and moisture in the air and protects it.
Aluminum profiles have high mechanical strength but low corrosion resistance. Pure aluminum has good corrosion resistance, but its mechanical strength is poor and it is easy to deform. This restricts the application of aluminum to a certain extent. For this reason, people add appropriate amounts of magnesium, copper, zinc and other metals to aluminum to make each. The various types of aluminum alloys greatly improve the mechanical strength of aluminum, and the application range is greatly expanded, but the corrosion resistance is inferior to that of pure aluminum, and thus it may be corroded by oxidation. This requires a painting process to protect the aluminum profile.
In addition to high corrosion resistance, the aluminum profiles treated by the painting process also have diversified colors, which can make the layout more coordinated.
One of the impacts of the slip line industry (steel industry)
According to the Central Financial Report, this year, due to the decline in domestic and international steel prices and the sluggish demand, the performance of many domestic listed steel companies in the first half of the year dropped sharply or even lost. The total amount is as high as 10 billion yuan, and the steel industry is in an unprecedented crisis.
Large steel enterprises maintain their operations through continuous issuance of financing, and the industry is caught in a strange circle of “more losses and more investmentâ€, which has aggravated the contradiction between supply and demand and the financial pressure of enterprises. It is expected that steel prices will continue to fluctuate within a narrow range in the near future. Steel production remained high, and demand was weak and difficult to change. Steel mills lowered prices and hit market prices. Steel prices are expected to continue to bottom out, and steel companies are under pressure to lose.
At present, China's steel industry is overcapacity and concentration, and inflation is becoming more and more serious, which will further accelerate the disintegration and restructuring of steel companies.
The downturn in the steel industry has also affected the development of related industries. The slip line industry is one of them. In the early stage, in order to improve the economy, expand the plant to increase production capacity, and drive the economy to rise further. The new steel plant will generally use crane equipment as a crane equipment. The essential part of mobile power supply, the slip line industry is also divided into the industry. In the current downturn, the slip line industry has rarely received corresponding orders.
I hope that the country can come up with the corresponding adjustment plan as soon as possible. The steel we produce is mainly used by real estate developers. We must change the previous policy and produce some high-performance steel for import and use in Europe and the United States, so as to ensure that the products are not left over. Can improve the business economy. This will also bring new paralysis to our slip line industry.
The sliding contact line http:// has a wide range of applications, which has a great impact on China's machinery industry. Its quality has a very small impact on the results. Therefore, although it is a mechanical component, it can not be as important as it is. The main part of the machine, of course, only the quality of each component has been improved to drive the development of the entire machine industry, which will certainly promote the quality of life of the entire national. In order to achieve this goal, all industries are strengthening internal and external exchanges, and even earning a lot of money to learn from the ocean. After years of hard work, they have finally achieved some gratifying results, but there are still some problems, and the industry standard management work is an important one. Question.
With the development of the industry and the progress of society, people have found that the management of various industry standards needs to be continuously strengthened. Due to institutional problems and historical reasons, China has signs of backwardness relative to foreign countries in this respect, so it needs contemporary people and The diligence and dedication of the future people to make up for it, the reference is a powerful measure and a shortcut, but we must know how to master the core technology, not just fish but not fishing. Use its own real technology and system to continuously solve various problems that may exist in the future skid line industry.
