In recent days, major cities across China have been experiencing varying degrees of smog, causing significant disruptions to daily life and travel. Officials have emphasized the need for effective measures to accelerate industrial restructuring, promote energy conservation and emission reduction, and build a more sustainable ecological civilization. They also called for stricter enforcement of environmental protection laws and urged the public to take personal precautions. Addressing this issue requires a collective effort from all citizens and a widespread awareness of environmental responsibility.
The ongoing smog has not only raised public concerns about pollution but also sparked discussions among steel traders. Many are wondering whether the current weather conditions could lead to another round of incomplete energy-saving and emission-reduction targets, similar to what happened in 2010 or 2011. Questions have also arisen about the recent shutdowns of steel mills in Hebei, with industry experts suggesting that the government may implement temporary plant closures or impose stricter regulations on pollution levels.
As a high-energy-consuming and high-pollution sector, the steel industry plays a significant role in air pollution. Emissions of sulfur dioxide (SO₂) and particulate matter are major contributors to smog formation. According to data from Haixin Steel Network, in 1999, the steel industry ranked third in SO₂ emissions nationwide, while smoke and dust emissions accounted for 6.2% of total industrial emissions, placing it fourth. Dust emissions reached 20%. By 2010, the national steel industry emitted 1.7665 million tons of NOx, 931,000 tons of nitrogen oxides, 562,800 tons of dust, and 934,700 tons of particulate matter—accounting for 9.5%, 6.3%, 9.3%, and 20.7% of total industrial emissions respectively. These figures highlight the critical need for improved pollution control in the sector.
While some argue that the steel industry is not the main cause of smog, many believe that the concentration of steel plants in northern China contributes significantly to haze formation. In the long run, the severe smog in Beijing and other northern cities is likely to trigger major policy changes that could negatively impact traditional energy-intensive and polluting industries, including steel production.
Hazy weather results from a combination of natural and human factors. The steel industry must continue efforts to reduce its environmental impact, and the possibility of government intervention remains real. Even without smog, domestic steel mills already face intense pressure to cut emissions, and the current weather conditions may just serve as a catalyst for further regulatory action.
Polishing Buffing Wheel
Bias Airway Buffing Wheel, also called as airway buffs, airflow buffs, Ventilated buffs. The special air folded structure brings bias airway buffing polishing wheel strong cutting force, high brightness, fine finishing, can cool the workpiece surface at a very short time. Make airway buffing polishing wheel widely use on metal and non metal products polishing, such as wood, stainless steel, aluminum, copper etc. Involved in variety of industries: furniture, automobile spare part, hardware, building materials,etc.Â
Airway buffs are a type of buffing and polishing wheel that is made up of multiple plys of cotton Cloth attached to a steel center plate. Each cloth layer of these 16-ply wheels is attached to the steel plate in a way that forces the cotton to form pleats.
High-speed buffing and polishing wheels can create a lot of heat from the constant friction of the wheel, surface being buffed, and Polishing Compound grinding at the same time. The fold are designed to increase airflow so that you can buff and polish at a lower temperature. This allows you to work continuously longer than traditional polishing wheels, extends the overall serving life of the airway buff, and lowers the chance of causing damage or burn to the object you are polishing.
The different colors of airway buffs are not there to let you work with your favorite color. Each of these colors has a different firmness/softness of the cloth pieces which are meant for different steps in the polishing process. You should also consider pairing each color buffing wheel with the appropriate color buffing compounds.
