abrasion The Al2O3 content of the ceramic inner lining reducer is more than 95%, and the microhardness is HV1000-1500. It has high wear resistance, and the wear resistance is ten times higher than that of the quenched carbon steel, and the superior tungsten carbide bit. corrosion The ceramic material is neutral, chemical property is stable, has excellent corrosion resistance and acid resistance, resistant to various inorganic acids, organic acids, organic solvents, its stainless steel corrosion degree is more than ten times. temperature The temperature is above 2000 degrees Celsius, and it works in the range of -50celsius~900 degrees Celsius for a long time. Easy welding Ceramic adjustable pipes can be welded, flanges, flexible connectors and other fast connections, very easy to install. Clean, easy to maintain The wall is smooth, which can prevent fouling, dirt and self cleaning function. Seal.

The ceramic tube is the corundum and the inner corundum. The hardness of corundum layer Vivtorinox is 1100-1500 (Rockwell hardness 90-98), equivalent to tungsten cobalt hard gold. The high wear resistance is 20 times higher than that of the carbon steel pipe. It is superior to the ordinary corundum grinding wheel. It is still a variety of corundum grinding wheel grinding hardened steel main wheel. The ceramic Guan Gangyu corundum wear layer can be picked up. The wear-resistant ceramic tube corundum layer can be formed mainly by a few millimeters thick, the Moir hardness is 9, second only to the diamond and the silicon carbide, all oxides, this is the highest hardness. Only about 20% of alumina, most of which are SiO2, SiO2 Moir hardness is 7. rare high chromium wear resistant alloy tube or Vivtorinox hardness is about 400 (Rockwell hardness is about 50), and the hardness of corundum is third. Therefore, the wear resistance of wear-resistant alloy steel pipe and casting pipe is a qualitative leap from the composition and structure, and the thickness of ceramic tube compared with them.

President Vučić praised the acquisition of the Chinese company on day 5 for the success and progress of the Smederevo steel plant in Serbia. Vucic made the above statements during the celebration of the second anniversary of the official takeover of the Smeder Revo steel plant by Hegang Serbia. He thanked the workers for their efforts to achieve the corporate objectives and emphasized the importance of steel mills in the city of Smederevo and the entire Serbian economy.

South Korean steel pipe exports continued to decline due to US tariff measures. According to data released by the Korea Iron and Steel Association, in May, South Korean steel pipe exports fell by 28.1% to 168,517 tons, compared with 274,431 tons a year ago. In the first five months, Korean steel pipe exports totaled 10,869,48 tons, down 17.7% from 1,321,136 tons in the same period last year. Although the US shale gas development has a large demand for petroleum special pipe (OCTG), the export of Korean oil special pipe is significantly reduced by the US import quota. In May, South Korea’s oil-specific pipe exports reached 5053 tons, down 95.3% from 108,632 tons a year ago. In contrast, in May, South Korea’s wire pipe exports increased by 11.7% year-on-year, from 40,641 tons to 49,842 tons. This is because in the US anti-dumping tax items, the tax rate of line products is lower than other products. However, due to restrictions on US import quotas, future exports of line management will not be more optimistic. At the same time, in May, South Korea's large-diameter spiral pipe exports fell by 63%, from 2,297 tons a year ago to 849 tons; the output of rolled pipe increased by 4.3%, from 48,987 tons to 51,101 tons; large caliber The output of the electric resistance welded pipe also increased by 142.6%, from 3,830 tons to 9,291 metric tons.

World Steel Dynamics (WSD) held the 33rd Global Steel Survival Strategy Conference, which released the annual list of “World's Most Competitive Steel Companies”. South Korea's Pohang ranked first with 8.37 points (out of 10 points). This is the ninth time that Posco has won this award since 2010. Posco’s operating profit last year exceeded 4.62 trillion won ($3.8 billion), the highest level in six years, and its combined sales revenue was 60.66 trillion won ($54.2 billion).

In the week ending June 30, 2018, the domestic domestic crude steel output was 1.78 million short tons, and the capacity utilization rate was 76%. In the same period last year, the output was 1.747 million short tons, and the capacity utilization rate was 74.9%. Crude steel production rose by 1.9% year-on-year and rose by 0.5% on a week-on-week basis. In the week ending June 23, 2018, the domestic domestic crude steel output was 1.772 million short tons, and the capacity utilization rate was 75.6%. After adjustment, by June 30, 2018, the cumulative crude steel output in the United States was 45.514 million short tons, the capacity utilization rate was 75.5%, and the cumulative crude steel output rose by 1.7%. In the same period of 2017, it was 44.439 million short tons and 74.4%. The weekly crude steel output was divided into regions, with 215,000 short tons in the northeast region, 653,000 short tons in the Great Lakes region, 187,000 short tons in the central and western regions, 652,000 short tons in the south and 74,000 short tons in the west, totaling 17.81 million short tons.
