Stainless steel is a product of “energy saving and emission reduction” with obvious benefits. It is a product that can effectively avoid “global warming and greenhouse effect”. The specific way is to replace ordinary carbon steel, and compare with ordinary carbon steel, showing the superiority of “energy saving and emission reduction” of stainless steel.
First, in the production process, stainless steel compared with ordinary carbon steel, has obvious energy saving and emission reduction benefits. Generally speaking, in the process of iron and steel production, the energy consumption per ton of steel for short process of stainless steel process from electric furnace steel to stainless steel hot rolled coil is 280 kg, and the comprehensive energy consumption of ordinary carbon steel for ordinary carbon steel is 625 kg. Short process stainless steel produces more than 55% energy savings over long process carbon steel production. The CO2 emissions per ton of steel in the short flow process of the stainless steel hot rolled coil from the start of the electric furnace to the stainless steel hot rolled coil is 507 kg, and the CO2 emission of the ordinary carbon steel of ordinary carbon steel, which includes the iron making system and the common carbon steel hot rolling, is 1860 kg. The production of stainless steel in short flow process reduces CO2 emissions by more than 72% over long process carbon steel production.
The two is in the application field, the advantage of stainless steel is more obvious. As stainless steel is a high quality steel, it has the characteristics of rust, corrosion resistance, beauty, high strength and one hundred percent recovery. In practical application, it can further show the social benefits of energy saving and emission reduction. For example, new stainless steel wagons made with stainless steel hot rolled rolls can reduce the initial steel consumption by 15% and reduce the consumption of steel by about 55% in the whole life cycle, compared with the domestic original general gondola car made of ordinary carbon steel. According to the life cycle coal consumption per ton of coal, it can save more than 75%. In this way, every additional 1 tons of stainless steel can replace 4 tons of multi carbon steel. In consideration of the factor of saving steel in the process of stainless steel manufacture and application, the energy saving of stainless steel is 84.25% than that of ordinary carbon steel, and the emission of CO2 is reduced by 87.16%.
All in all, stainless steel is a product with remarkable results in energy saving and emission reduction, and is a product that is beneficial to avoid “global warming and greenhouse effect”. The production of stainless steel products in China’s advanced enterprises is more conducive to “energy saving and emission reduction” and the avoidance of “global warming and greenhouse effect” than the production of stainless steel products in other countries and regions. Therefore, the development of the stainless steel industry in China is not only in accordance with the national interests of our country, but also in the interests of the whole human reduction of carbon dioxide emissions and the avoidance of “global warming and greenhouse effect”.
Further consideration of the application of stainless steel in nuclear energy makes it possible to promote nuclear energy, and further reduce CO emissions compared with thermal power plants. In the application of water supply and drainage systems, CO2 emissions can be further reduced by reducing water pollution and waste. In the application of water treatment, the application of water desalination, the application of clean food, the application of energy efficiency and the application of one hundred percent recyclable, the effect of “energy saving and emission reduction” and avoiding the “greenhouse effect” of stainless steel is greater.
In the past, the application of stainless steel in many aspects is from the high-end, beautiful and so on. It is the demand after the improvement of the living standard, not the necessary necessities in people’s life. Then, from the new angle of “energy saving” and “avoiding the greenhouse effect”, the stainless steel should be all human. The necessities of the continuous development of life.
