The metal baler can squeeze various metal scraps, steel shavings, scrap steel, scrap iron, scrap copper, scrap aluminum, aluminum shavings, disintegrated car shells, waste oil drums and other metal raw materials into various shapes such as cuboids and cylinders. Qualified charge. It is convenient for storage, transportation and recycling.
For this reason, the Chinese traditional materials industry needs to solve the following problems:
1. It is necessary to make rational use of mineral resources, especially comprehensive utilization of domestic mines. At present, the utilization rate of complex ore in my country is very low. For example, the Baiyun Obo Iron Mine is rich in rare earth resources, accounting for more than 90% of the total reserves and 5/6 of the world's total reserves. It is known as "the world's rare earth treasure house", but the current utilization rate is less than 10%.
2. Improve production process, reduce energy consumption, reduce pollution, vigorously develop circular economy, and attach importance to ecological design. Practice has proved that using 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.
3. The development of traditional materials should not be controlled. It is also necessary to grasp the trend of domestic demand and capacity changes, 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.
4. Establish a mechanism to reverse the fact that material production is heavily dependent on resource imports. China's mineral resources are largely dependent on foreign imports. According to 2012 statistics, chromium is almost dependent on imports as the main raw material of stainless steel, and the import rate of strategic resources of copper concentrate is also between 60% and 70%.
