Since the 1980s, a large number of scrap processing equipment, such as metal balers, metal shears, metal vertical balers, crushers, box shears, gantry shears, etc., have been used in the Chinese market. Antaqi. Metal balers and metal shears are the most widely used devices on the market today. Because of its low price and convenient operation, it has been accepted by the majority of users, but its low efficiency has increased the cost of operators and lost the competitive advantage of the industry. Traditional materials such as steel, non-ferrous metals and plastics have contributed greatly to the rapid development of the Chinese economy. The variety of traditional materials, low prices, high cost performance, still shows strong vitality, but there are still problems such as strong resource dependence, high energy consumption and serious pollution.
Metal balers, especially China's traditional materials industry, need to address the following issues:
The first is to improve the production process, reduce energy consumption, reduce pollution, vigorously develop circular economy, and pay attention to ecological design. Practice has proved that the use of 1 ton of scrap steel can save 1.3 tons of iron ore, reduce energy consumption by 50%, and reduce carbon dioxide emissions by 1.4 tons.
Second, we must make rational use of mineral resources, especially the comprehensive utilization of domestic mines. At present, the utilization rate of complex ore in China is very low. For example, the Bayan Obo iron ore deposit is rich in rare earth resources, accounting for more than 90% of the country's total reserves, accounting for 5/6 of the world's total reserves. It is known as the "world treasure house of rare earths", but its utilization rate is less than 10%.
The third is to establish a security mechanism to reverse the fact that material production is heavily dependent on the import of resources. China's mineral resources are largely dependent on foreign imports. According to statistics, in 2012, chromium as the main raw material of stainless steel, almost completely dependent on imports, the strategic resource import rate of copper concentrate is also between 60% -70%.
Fourth, the development of traditional materials should not be restricted. It is also necessary to grasp the changing trends of international and domestic demand and capabilities, coordinate development, and avoid redundant construction. In addition, the development of steel, non-ferrous metals, cement, plastics and other materials should have a reasonable proportion.
