In recent years, the reform of supply and demand system of scrap steel industry in China has achieved initial results, but it is far from the goal of modernization, scale and standardization of scrap steel processing and distribution system matching China's iron and steel industry.

The national policy support system and technical support system are still weak;

The total amount of scrap consumption increases sharply year by year, but the growth rate of scrap supply is much lower than that of crude steel production, which keeps the scrap ratio at a low level.

The production of domestic scrap steel resources has increased every year, but it is not self-sufficient, the resource gap is still large, and the overall market pattern is in short supply;

The level of industry technology and equipment is still in the initial stage, the quality of scrap steel needs to be improved, and it can not meet the needs of "concentrate into the furnace".

Among the large number of metal renewable resources, the wide range of sources should be scrap steel.

There are three sources of scrap steel:

One is the return of scrap steel from inside steel enterprises;

Second, processing scrap steel from metal machining enterprises;

Third, depreciated scrap steel and steel from various sectors of society, such as scrap equipment, vehicles, ships and civil steel products.

According to the statistics of experts over the years, the annual output of scrap steel in China is about 42% of the annual output of steel, in 1995, China's steel production has reached 94 million tons, the existing scrap steel resources of nearly 40 million tons, of which 75% need to be broken and processed by crusher.

Scrap iron and steel is an important renewable resource, the use of scrap iron and steel resources development and utilization is an important branch of the field of recycling, in the steel industry in an increasingly important position, with broad prospects for development. Scrap steel is an important raw material in iron and steel industry. Using Shende scrap crusher to extract and treat scrap steel materials is a common and effective method in China's iron and steel industry.

From all walks of life of scrap steel variety, complex structure shape, physical and chemical properties vary, must go through a variety of professional metal crusher processing, in order to be converted into qualified raw materials. China has nearly 30 million tons of scrap iron and steel resources every year need to be processed by crusher. With the development of low-carbon economy, scrap steel will increasingly highlight its resource advantages and trends.
