China Steel Association, after investigation, after listening to expert advice and recommendations concerning the drafting of the "on steel industry in the country", "thinking and strategic planning draft proposal" Twelve Five, in consultation with the staff, the association will organized experts to concrete implementation, improve, in order to promote the "second five" steel industry to achieve greater development. Steel industry due to its economic and technological superiority, carbon emission reduction, recycling economy and may industrialization, industrial development, better able to adapt and meet the current needs of the national economy, it will become a huge market, many companies one of constant innovation, full of vigor and vitality of the emerging industry. Institute for Information Industry Outlook "2014-2018 China steel structure industry Market Outlook and Investment Planning Analysis Report" analysts believe that the price of steel works, "Twelve Five" period, obtain policy support steel industry is expected in the marine engineering, residential and areas of the bridge to flex its muscles to achieve doubling production. Metal surface rust methods: manual processing, mechanical treatment, chemical treatment, and flame treatment four. (1) manual handling: manual handling mainly used blade, wire brush, emery cloth, broken hacksaw and other tools by hand to knock, shoveling, scraping, brushing, sand approach to achieve remove rust, which is the traditional painting methods rust is the easiest way, without any environmental and construction conditions, but because of poor efficiency and effectiveness of the stream of steel manufacturers, only a small range of suitable rust treatment. (2) mechanical descaling method of mechanical descaling method is the use of a number of electric, pneumatic tools to achieve the clear purpose of rust. Common power tools such as electric brush, electric wheel; Fengdonggongju wind moving brush. Electric and pneumatic brush brush is to use a special circular wire brush rotation, by the impact and friction of the skin cleaned rust or oxidation, especially for surface rust, the better, but it is difficult to remove deep rust. Electric wheel is actually portable grinder, high-speed rotation can move the company in the hands of steel structure design, the use of the wheel to remove the rust, the better, especially for deep rust, its working efficiency high steel structure, construction quality is also good, easy to use, is an ideal tool rust. But in the operation should be careful not to punch through the metal skin. (3) sand blasting, shot peening method blasting, shot peening method with the former section clearance method using an old film. (4) flame treatment flame treatment method is the use of gas torch difficult to remove by hand on a small number of deep rust spots, were red-hot, so hot to make changes in the chemical composition of the oxide rust rust to achieve the purpose. So that this method should be mindful not to let the metal surface burn, and to prevent large surface heat deformation.
