If the domes of large buildings such as gymnasiums and exhibition centers are all replaced with aluminum profiles, it will save a lot of annual maintenance costs. Colorful aluminum sheet scan also be used in the construction industry.
Lighter weight, more corrosion-resistant, 3 times longer lifespan, and maintenance-free. All-aluminum flyovers will become the main stream of "aluminized" cities in the future. In the field of heavy trucks, aluminum lightweight carriages are 1/3 lighter than steel. If there is one heavy truck nationwide If you replace it with an aluminum carriage, the annual oil saving is equivalent to the amount of oil my country imports from Russia every year. The per capita consumption of aluminum is 90 kilograms, while my country is only 30 kilograms. From 30 kilograms to 90 kilograms, how many occupations are involved in the colorful aluminum plate during this period use?
On the one hand, my country's electrolytic aluminum production capacity is overcapacity, and on the other hand, the aluminum industry has a huge space for imaginary use. After more than ten years of high-speed development, my country's aluminum industry is at the crossroads of difficult choices. The output value ranks first in the world. However, this dazzling effect cannot hide the increasing contradictions of the Ministry of Industry: the production capacity of electrolytic aluminum and recycled aluminum is seriously excessive, the occupational energy consumption remains high, and the emission pollution is alarming.
Under the sluggish aluminum industry situation in my country, a series of regulatory actions by the government have naturally been triggered. From the aluminum professional specification document to a new round of screening outdated production capacity, it has not been able to change this professional dilemma in the short term.
On the contrary, the negative factors continue to ferment. Due to the large investment volume of electrolytic aluminum, the low investment threshold, and the simple formation of industrial clusters, some localities regard electrolytic aluminum as a pillar industry regardless of whether they have resources and power conditions, and give enterprises more support policies such as electricity price concessions. A large number of outdated production capacity are maintained. The industry expects that by 2015, the total production capacity of new and old nationwide will reach 40 million tons, far exceeding the output value of the "Twelfth Five-Year Plan" policy of 24 million tons. In 2012, the national market consumption was 19.02 million tons, even if Primary aluminum consumption is increasing by 9% per year, and overcapacity is also extremely serious.It is welll known that a lot of slag occurs in the production process of striped aluminum sheets. Just like the cinder we use in our daily life, it is used as domestic waste and has no use value.A large amount of accumulation is very harmful to the environment. Zebra board production waste is of great economic value.Blast furnace slag powder is a new building material developed and popularized in recent years. The water-quenched blast furmace slag is crushed to a certain fineness, which promotes the increase of the activity of CaO, SiO2, and AI2O3, and the formation of calcium silicate hydrate products, and flls in the gaps of cement concrete, which can greatly improve the density of concrete; The lower-strength Ca(OH)2 crystals are converted into higher-strength calcium silicate hydrate gels, resulting in significant improvements in a range of concrete functions.Concrete mixed with slag powder has the characteristics of low heat of hydration, corrosion resistance, strong bonding force with steel bars, strong impermebility, shrinkage resistance of various functional concretes, and has excellent working viscosity, cohesion and anti-segregation functions. In many areas and regions, slag powder has been widely used in dam projects of various functional concretes, and has excellent working viscosity, cohesion and anti-segregation functions. In many areas and regions, slag powder has been widely used in dam projects underwater projects, road projects, coastal anti-corrosion projects, large-scale construction projects, etC., so it has a broad market prospect.
The blast furnace water slag to make water slag fine powder is one of the effects of blast furnace slag in the deep development and utilization of the building materials industry. The water slag fine powder directly replaces part of the cement in the concrete, which can reduce the cost of concrete production enterprises and generate direct economic benefits; Grinding equipment, directly selling and setting fine powder, can improve the economic value of blast furnace slag, expand its use, and generate greater economic benefits.
