Why Recycle Waste Graphite

Graphite electrodes have many processing processes, large demand for raw materials, and in actual production, there will be a part of waste. For example, in the production process, the blank is broken, or the physical and chemical indicators are not up to the standard, so the graphite electrodes produced will not be put into qualified products, resulting in waste. Another is that steel mills use graphite electrodes for smelting, there are furnace dropout or serious oxidation phenomenon, so that graphite electrodes can not continue to use, become waste.

1. The productivity of graphite electrode decreases year by year.

The bottom of the graphite electrode industry was in 2016. Before 2016, the price of graphite electrode fell year by year, and it has been falling for 5-6 years. A large number of graphite electrode manufacturers closed down, stopped production and reduced production, resulting in only one of the remaining big charcoal (165-175,000 tons per year) with an annual production capacity of more than 100,000 tons, and Jilin charcoal (35,000 tons per year, the limit capacity of 50,000 tons).

2. Turning Point of Graphite Electrode Industry

The turning point of the industry is in October 2016, when the government began to reform the supply side of strip steel, leading to a sharp drop in scrap prices, which led to a turning point in the comparison of economic benefits between EAF steel and blast furnace-converter steel. That is to say, since October 2016, the economic benefits of EAF steel have continued to be significantly better than that of converter steel.

3. Scrap-EAF Steel Enters Dividend Period

According to the Regulation Policy for Iron and Steel Industry (Revised in 2015) (Draft for Consultation) issued by the Ministry of Industry and Information Technology on March 20, 2015, it is clearly required, & quot; to encourage the promotion of short-process steelmaking technology and equipment using scrap steel as raw material. By 2025, the ratio of steel-making scrap to steel-making scrap in China's iron and steel enterprises will be no less than 30%, and the scrap steel processing and distribution system will be basically established-quot;.

In order to achieve this goal, the 13th Five-Year Development Plan of Scrap Iron and Steel Industry formulated by China Scrap Iron and Steel Application Association put forward that by 2020, the scrap steel ratio of steel-making in China will be quot; the 12th Five-Year-quot; and the doubling will reach 20%. In 2016, the ratio of steel scrap to steel scrap in China is 6%, which is far from the target set by the Ministry of Industry and Information Technology and the Association.

In response to China's policy of attaching great importance to resource conservation and environmental protection, the recycling and recycling of graphite electrodes not only saves costs and raw materials, but also is reused in the production of various industries, which responds to the call of the state and promotes the development of national economy. China's recycling economy technology, equipment, product trading and recycling industries are growing.
