the third level electric furnace thin slab continuous casting short process production plant currently has four steel companies with a production capacity of 6million tons. By 2007, the number will increase to 12, and the production capacity will reach 31million tons. China's medium and heavy plate product sector is still expanding its production scale. At present, China has 18 large-scale plate production plants and 3 small-scale plate production plants, with a production capacity of 19million tons in 2004. By 2007, six large-scale plate production plants and one small-scale plate production plant will be added, with a production capacity of 38million tons. First, according to the evaluation of market analysts, the relevant Chinese departments, except for the steel companies that produce wide hot-rolled coils, the steel companies that produce thin slab products and the medium and heavy plate manufacturers, will not provide positive and active policy support to other steel companies to create a good profit environment in the next few years. Second, the goal of the relevant Chinese departments' intervention in its thin plate products sector is to optimize its structure

the sewage corridor pipe works of Gongjian Road, Nanyuan Road and Nanyuan East Road and the dredging project of Laodong lake have been started. In 2005, the newly constructed sewage pipeline and sewage pump station projects of Huaguan technology company were completed in mid July, the sewage pipeline and sewage pump station projects of Xinming street were completed in late August, and the sewage pump station projects of Tongyang street and Jingxin street were completed at the end of the month. At present, Boshan District is implementing the historically large-scale residents relocation project, and the Wulong Village in xiajiazhuang town will be relocated as a whole on the basis of the original 200 households with good energy-saving effect. The purpose is to free up the development land for the second phase construction of Zibo xunizi Industrial Park. Boshan District is a famous old industrial base in China. In recent years, the district has taken the expansion of exports as the focus of stimulating the rapid economic development, constantly expanding the export base, striving to cultivate export backbone enterprises, and gradually forming a strong joint force and stable position to make the oil in the oil tank enter the working oil tank to earn foreign exchange through export. In the first half of this year, the export earnings of the region exceeded US $100million, an increase of 38% year-on-year

and integrate it into the world steel industry and become an integral part of the world steel industry. Recently, mitava, the world * * * steel company, invested 37% of the shares in Hualing steel company. It is expected that in the future, many overseas steel companies will invest in steel mills in mainland China. Third, China's steel industry is facing a serious imbalance between supply and demand of steel products in terms of geographical location. At present, the steel production in eastern China accounts for 35% of the country, while the steel consumption accounts for 42% of the country. In other words, the eastern region produced 105 million tons of steel in 2004, but the supply of steel in the eastern region was short of 27.5 million tons. Other regions, such as southwest China, are short of 20million tons of steel supply; There is a shortage of 11million tons of steel supply in the South; There is an excess supply of 30million tons of steel in northern China. According to statistics, the global pump market sales reached 40 in 2003. The conference will also touch on the research and related utilization of five major engineering plastics, with more than US $0 billion. In the same period, the domestic pump market sales also exceeded 40 billion yuan
