Metal balers reduce energy consumption and reduce pollution
Since the 1980s, a large number of scrap processing equipment have been used in the whole market in China, such as metal balers, metal shears, metal vertical balers, shredders, box shears, gantry shears, etc. . But they all have their own strengths and weaknesses. Metal balers and metal shears are the most widely used equipment on the market. Due to their low price and convenient operation, they have been accepted by the majority of users, but their inefficiency has increased the cost of operators and lost the industry. Competitive advantage.
Traditional materials such as steel, non-ferrous metals and plastics have made great contributions to the rapid development of China's economy. Due to its variety, low price and high cost performance, traditional materials still show strong vitality, but there are still problems such as strong resource dependence, high energy consumption and serious pollution.
In particular, the Chinese traditional materials industry needs to address the following issues:
First, 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 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 the current 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 the statistics of 2012, chromium is almost entirely dependent on imports as the main raw material for stainless steel, and the strategic resource import rate of copper concentrate is also between 60% and 70%.
Fourth, the development of traditional materials should not be controlled. It is also necessary to grasp the trend of changes in international and domestic demand and capacity, coordinate development, and avoid duplication of construction. In addition, the development of steel, non-ferrous metals, cement, plastics and other materials should have a reasonable proportion.
