Overview: in 2019, China's crude steel and steel production will be 996 million tons and 1205 million tons respectively, with a year-on-year increase of 8.3% and 9.8% respectively, and the crude steel output will reach a new record. Iron and steel has a certain scrap period, and every 10-30 years or so is a cycle cycle (the scrap cycle of general steel products is 10-30 years). After the scrap period is reached, it can be recycled as scrap, which is a kind of renewable resources and can be used indefinitely. The process of steelmaking rolling steel products using scrap recycling steelmaking rolling has the advantages of less natural consumption and high utilization rate.
From 2015 to 2019, the number of scrapped motor vehicles in China increased year by year. According to the statistics of the market system construction Department of the Ministry of Commerce, the number of scrapped motor vehicles in China will reach 2.295 million in 2019, an increase of 15.3% compared with that in 2018. At the same time, the number of existing enterprises of recycling and dismantling ELVs in China has increased rapidly. The resources obtained from the recycling and dismantling of ELVs mainly include scrap steel, scrap nonferrous metals, waste plastics (7210, - 5.00, - 0.07%), waste rubber (14895, 30.00, 0.20%), waste glass (1715, 3.00, 0.18%) and waste oil. 72.0% of waste steel and 6.0% of waste nonferrous metals can be recovered from each ton of renewable resources. The scrap iron and steel part of automobile dismantling parts is the most important crushing raw material of crushing materials. With the gradual increase of automobile scrapping and dismantling quantity in China, the usage of crushing materials is also gradually increasing.
