Energy conservation and emissions reduction

Recently, there are merchants will scrap sales foreign bidding in public way, caused quite a stir in the industry. Coupled with the recent sales of scrap steel company constantly emerging, become the industry a scene, attract the attention of many stakeholders. In the steel industry, if the process of steelmaking as cooked porridge, compared to rice iron ore, pig iron to rice, then people will put the image of the scrap steel as "rice dumpling". Do with rice porridge, compared the new processing rice peel - washing rice cooking such a process, save time and effort degree of everyone.
Then the survival status of the current domestic steel scrap? Way out, development trend of future scrap steel? With these questions, the author interviewed LiuYing net scrap steel analyst as well as some related people in the industry.
Energy conservation and emissions reduction, scrap steel is far better than that of iron ore
As is known to all, scrap is currently the only raw material commodities can take the place of iron ore. The current our country is still in the period of industrialization and urbanization speed up the development, the demand for steel continues, demand for iron ore resources is large, but the lack of domestic mineral resources, and low taste, high iron ore external dependence, not conducive to the development of steel industry in the long run. Relative to iron ore, LiuYing said iron ore for non-renewable resources, mining resources in some countries is less part of environment pollution and destruction of at the same time also brought in high energy consumption, high pollution, and scrap steel as a recyclable must make full use of renewable resources. Relevant personage also revealed from steel - products - use - dead - recycled steel, each 8-30 years for a cycle, accumulation, generation, recycling, and natural loss is low.
How much demand from the point of the steelmaking process, scrap steel mainly depends on the discretion of the steelmaking process and precision of furnace charge and purity requirements. Steelmaking process is higher, the burden of the higher precision and purity requirements, the more demand for steel scrap. For the entire international market, LiuYing said some of the more developed countries started early industrial development, based on steel scrap cycle combined with the steel-making technology is relatively mature, has massive USES electric furnace production is given priority to with scrap materials, and our country is still in industrial development period, the domestic is still in the traditional process of converter is given priority to, status in quo of scrap cost is higher than the iron ore is an important factor. Is the present domestic steel industry, relevant personage says in the short term difficult to achieve large-scale electric furnace production replace converter technology innovation, but improve the scrap steel in converter application than, also can reduce consumption of iron ore, achieve energy conservation and emissions reduction. In steel production process, 60% energy consumption of iron and steel production are focused on sintering, coking, iron and other processes, this stage a large amount of energy at the same time also brought the pollution emissions. While recycling high-purity steel scrap is equivalent to skip these energy-intensive link, directly into the converter, electric furnace process. According to the relevant institutions, compared with the use of iron ore, scrap and can save energy 60%, water 40%, reducing emissions of waste water, waste gas, waste residue, 86% and 72% 76%. Each multi-purpose 1 tons of scrap steel, can use fewer, 1.7 tons of ore concentrate by 4.3 tons of raw iron ore mining. The comprehensive utilization of iron and steel scrap, the foot is visible in the role of energy conservation and emission reduction, green environmental protection.
Outside the scrap status quo - "warm" "hungry"
LiuYing pointed out that the scrap there are three main sources: enterprises produced mainly from scrap steel scrap, scrap society mainly includes scrap vessels, tanks, planes, houses, Bridges, cars, etc., as well as imports of scrap steel. Mills sell scrap quantity is limited, as the national enterprise constantly improve the management innovation, technology, equipment, steel mills produced per unit of production scrap will be less and less. Social scrap recycling accounted for a large proportion, but compared with developed countries, the low industrial integration, every year nearly millions of tons of gap, while filling the gap from scrap steel import.
LiuYing said although every year there are tens of millions of tons of scrap steel domestic resources, but the scrap steel resources in our country at present is not enough, most of the iron and steel enterprises is still in a state of "do not have enough to eat".
Otherwise relevant experts said, Japan earthquake in middle of march this year to import scrap steel market and the domestic steel scrap market in China has brought great influence. Japan earthquake of Japan in Tokyo bay area of five major steel mills such as Nippon steel production or BanTingChan, varying degrees of destruction of production facilities, Japan as the second steel production country, the first steel exporter, the main production of steel mills and production will promote China’s steel production, expanding steel exports, driving increased demand for China’s iron and steel scrap, promote domestic steel scrap market rally. The rising market trend, may affect the scrap steel markets work throughout the year. Japan is China’s scrap steel import country for many years, our country as well as scrap steel in Japan. 09 from Japan imported 4.46 million tons of scrap steel in China, for about a third of scrap steel imports in our country, following the second after the United States. Under normal condition, Japan has a lot of scrap steel exports, further increases the spare of the scrap steel mills cut sharply, pouring into the Chinese market, promote China’s scrap imports increase. Increased imports would curb domestic steel scrap market price growth.
Scrap prospect -- "chaoyang" government and enterprises still need to play to be completed
Scrap steel enterprise as many renewable resources recovery industry, there is a weak foundation and develops slowly, some disconnect with the modernization process, but with the development of economy, renewable resources recycling in the position and role of the national economy growing. Is someone called her in the 1980 s: abandon one of wen’s worth, the gold of two thousand, now also someone praise she is a sunrise industry.
During the "twelfth five-year" countries have the transformation of the mode of economic development and to advocate energy conservation and emissions reduction on the agenda, this year is the "twelfth five-year" the start of the implementation, scrap steel industry should seize the moment to a new level.
China association secretary-general Li Shubin scrap application was pointed out in the meeting, clearly put forward national iron and steel industry policy, gradually reduce the iron ore proportion and increase the proportion of scrap steel. Use alternative iron ore to make steel, iron and steel scrap from the source to solve the best way to iron and steel industry high pollution and high emissions.
